The Opportunity

6673049234a230.10962743961 300x225 - A Quick Take: A First-Time CircuitSolver User

Luke Paschall, owner of Aquious, a family-owned plumbing business in Reno, Nevada, faced the challenge of balancing the domestic hot water recirculation system (DHWS) at the newly constructed Canyon’s Edge Apartments.

This residential complex, consisting of two three-story buildings with a mix of one-, two-, and three-bedroom units, required a reliable and efficient solution to ensure consistent hot water delivery to all apartments.

Aquious, known for its expertise in plumbing and tankless water heater services for residential and commercial properties, is led by Paschall, a third-generation plumber. Regarding this project, Paschall turned to his long-time friend and business associate, Matt Reilly of Zurier Company in Livermore, California, for advice. Reilly recommended using CircuitSolver thermostatic balancing valves, a suggestion Paschal was eager to explore.

The Solution

Canyon’s Edge Apartment complex.

The Canyon’s Edge Apartments complex has two buildings, each housing 24 units. To achieve optimal balance in the DHWS, Paschall installed eight ½” CircuitSolver thermostatic balancing valves in each building.

The first phase of the apartment complex was completed in May 2024, and Paschall was immediately impressed by the ease of installation and the effectiveness of the valves.

Paschall remarked that the installation process was incredibly straightforward. “I turned on the hot water, waited a bit, and everything was automatically balanced. I walked away happy! I would tell [contractors] to install and walk away; no training or special equipment is needed.”

Paschall noted that the CircuitSolver valves eliminated the need for manual adjustments, which had been a challenge with previous projects.

“We have used manual valves before; typically, we would set each one to 1 gpm and let it run. However, in larger systems, we do have to go back and adjust them if it seems like the flow isn’t proper or there are temperature variations,” he explained. “It is not the most scientific way of doing it. With CircuitSolver, we did not have to set flow rates – we could plug and play.”

The Outcome

Six months after the installation, the Canyon’s Edge Apartments have been fully leased, and residents have not complained about hot water availability. The system has performed flawlessly, reinforcing Paschall’s confidence in the CircuitSolver solution.

Paschall and his team at Aquious plan to continue using CircuitSolver thermostatic balancing valves in future projects, and they are confident in their ability to provide reliable, dynamic balancing. “We have bid on several multi-family and commercial properties using CircuitSolver. It has become our go-to solution for balancing hot water recirculation systems,” Paschall stated.

What is a Tempering Valve Used For, and Why Do I Need One?

A tempering valve is used for tempering the hot condensate or hot water discharge from commercial or industrial equipment going to a drain to comply with local, national, and international plumbing codes. According to the IPC (International Plumbing Code) and most state codes, the maximum allowable temperature entering a sewer system is 140°F (60°C) to avoid damage to existing piping.

commericial kitchen dishwasher AdobeStock 470994545 300x183 - What is a Tempering Valve Used For, and Why Do I Need One?

Commercial dishwashers, humidifiers, sterilizers, boiler blowdown lines, and autoclaves produce 180°F+ (82.2°C+) wastewater.

This high-temperature discharge damages PVC piping, which can cause failed inspections, costly fines, interruptions to day-to-day business operations, and damage to personnel.

Tempering valves mix cold water into the equipment discharge to reduce the temperature to acceptable levels before it reaches any PVC piping or public sewers.

How Does a Tempering Valve Work?

Thermostatic drain tempering valves monitor water temperatures and control the cold water supply that mixes with the hot discharge, eliminating the risk of water or waste exceeding 140°F (60°C) going down the drain. If the hot effluent is above the specified set point of the valve (offered in 5-degree increments from 120°F to 140°F), the actuator senses the rising temperature. It signals the valve to open to allow cold water to temper the discharge fluid.

The drain tempering valve (DTV) is a mechanical valve that eliminates the need for electrical solenoid valves or thermostats. It is open only when the effluent exceeds the specified set-point temperature, usually 10°F below the full open temperature, so it conserves water by automatically turning off cold water when not needed.

Where is the Tempering Valve Located? 

The tempering valve’s inlet is connected to the cold water supply and installed into the drain line of commercial or industrial equipment. Hence, the flow passes over the thermal actuator to sense the temperature of the water going to drain and prevent over-temperature conditions.

What Are Common DTV Applications?

Industries such as restaurants, hospitality, healthcare, and manufacturing have equipment that requires tempered water before draining. A steam condensate drain cooler, or Drain Tempering Valve (DTV), is typically used in commercial dishwashers, boiler blowdown drain lines, humidifiers, autoclaves, sterilizers, automatic cleaning equipment, or any application discharging scalding water.

In the News: Legionella & the Cold Water Problem in Plumbing Engineer

Prepare Your Cold-Water Circulation System and Battle Against Legionella

The COVID-19 pandemic has brought attention to vulnerabilities in plumbing systems, including cold-water systems. Stagnation and warming of unbalanced cold-water systems during building closures have raised concerns about Legionella growth.

When cold water flow is minimal or stopped altogether, as seen during the recent lockdowns that left buildings unoccupied for long periods, disinfectant levels evaporate, and temperatures gradually rise to Legionella’s growth range (77–113°F, 25–42°C), leading to bacteria colonization and uneven free chlorine distribution throughout the system.

Legionella causes a pneumonia-type illness called Legionnaires’ disease and a mild flu-like illness called Pontiac fever. Legionella bacteria can grow and thrive in plumbing systems. When water containing Legionella is used for showers or water fountains, people can inhale or ingest and aspirate tiny droplets of contaminated water, which can lead to infection if the bacteria are present in a dangerous amount.

While much attention has been given to mitigating Legionella in hot water systems, there is a need for proactive measures in cold water systems. “There has been a heightened awareness in the industry focusing on Legionella Mitigation, particularly in domestic water systems,” explains Tom Ruggierio, Director of Sales, Commercial Plumbing, ThermOmegaTech.

The Veterans Health Administration (VHA) has taken a proactive approach in addressing Legionella mitigation in cold water plumbing systems at their Department of Veterans Affairs (VA) medical facilities by planning for “periods of low flow or non-use.”

The VHA 1061(1) directive states, “The use of piping system insulation, automatic drain devices, and recirculation to limit the rate and duration of an increase in cold water temperature in combination with appropriate biocide levels can effectively prevent Legionella growth.”

The Solution: Cold-Water Recirculation

Recirculating cold water eliminates stagnation, which promotes harmful bacteria growth, and provides consistent distribution of residual chlorine throughout the domestic cold-water system.

  • Keeps water moving
  • Maintains water quality to reduce stagnation
  • Ensures residual chlorine is distributed throughout the cold water system
  • Keeps water temperature in branches and risers evenly distributed, minimizing heat gain
  • VHA Directive

Balancing Cold Water Systems

CS CW Button 400x185 RGB 300x139 - In the News: Legionella & the Cold Water Problem in Plumbing Engineer

“The CircuitSolver® was designed to balance domestic cold-water systems (DCWS) and reduce the risk of bacterial growth,” Ruggierio explains. “Our engineers developed a valve that can dynamically react to the ever-changing conditions that systems may experience. This includes changes in building occupancy, expansion, reduced utilization, and other variables affecting system balance.”

The CSU-CW valve utilizes the same reliable and precise thermal actuator technology as the original CircuitSolver®. It addresses critical issues related to Legionella mitigation in cold water recirculation systems by maintaining a stable temperature. It accomplishes this by continuously monitoring the water temperature and modulating flow to maintain a set temperature at the end of each branch or riser.

The valve operates over a 10°F temperature range. For example, a valve specified for a desired return temperature of 60°F will open at 70°F (10°F above the desired return temperature). At 60°F, the valve is in its closed position. A bypass in the design always allows water to flow back to the pump so that the pump is never dead-headed.

The Use of Thermostatic Technology

ThermOmegaTech® is a world leader in designing and manufacturing self-actuating thermostatic valve technology. They recently turned their attention to battling the Legionella risk in cold water systems.

“The Cold-Water Balancing Valve (CSU-CW) from CircuitSolver® is the market’s first cold water thermostatic balancing valve,” Ruggierio says. “Manual balancing valves could be used, but they are not dynamic and won’t respond to the changing conditions experienced in both hot and cold domestic water systems.”

“CircuitSolver® technology was already an innovative balancing method for domestic hot water recirculation systems, and now there is a solution for cold water systems, too. It’s another step in the right direction to improve plumbing system designs,” Ruggierio says.

“To date, we have provided thermostatic cold water balancing for three VA facilities, with interest from a few others. The more we investigated it, the more we recognized the importance of recirculating cold water. This technology helps to mitigate not only Legionella but also other bacteria and water-borne pathogens from growing. Implementing a cold-water recirculation system is not a nominal task, but what price can one put on a person’s health and safety?” Ruggierio explains. “We are in the early stages of this process. I see interest in this growing over the next several years, expanding from the VA into other healthcare facilities and the hospitality industry.

To achieve stability, system balancing must continually address the ongoing changes occurring within a building. Thermostatic balancing valves adjust dynamically, providing the best opportunity for sustainability and Legionella mitigation.

Case Study: Valve Retrofit Eliminates Manual Balancing for Hot Water on Demand at Assisted Living Facility

David Texter, Lead Plumbing Engineer at Browne Engineering, discusses the benefits of specifying CircuitSolver® Thermostatic Balancing Valves for an installation project at the Twin Lakes Assisted Living Facility in Montgomery, Ohio.

Twin Lakes Senior Living Community FB 300x240 - Case Study: Valve Retrofit Eliminates Manual Balancing for Hot Water on Demand at Assisted Living FacilityThe two-story building was new, but the balancing valves were installed incorrectly, and Texter’s team had to retrofit the valves.

Texter stated that before using CircuitSolver®, the system was experiencing hot water issues. One portion of the building would get plenty of hot water, and another would not have any hot water.

The balancing issues for this project were easy to identify because there was a lack of installed balancing valves on all the loops. CircuitSolver® valves were chosen to help minimize the amount of individual balancing in the system.

Since CircuitSolver® is a thermostatic balancing valve, it automatically adjusts to temperature changes, making balancing an intricate design much more straightforward.

The team experienced significant time savings during installation by not needing a third-party balancer to balance the system. The contractor installed 20 CircuitSolver valves and turned on the system, and it automatically started to balance itself.

Texter said he didn’t hear from the contractor after the installation. It comes back to the balancing contractor and the extra effort they must put into starting the system. CircuitSolver® sped up the installation significantly by saving them the time typically set aside for balancing.

“CircuitSolver® has always been a leader in the industry,” Texter says. “The ease of balancing these valves far outweighs any benefit of a manual balancing valve.”

He emphasizes that the CircuitSolver® team facilitates easy purchases, specifications, installations, and technical support.

In the News: PHCP Pros Q&A with Director of Sales for Commercial Plumbing, Tom Ruggierio

The CircuitSolver thermostatic balancing valve has been overcoming water balancing issues for over a decade.

More than ten years ago, ThermOmegaTech developed the CircuitSolver, the first thermostatic balancing valve used in domestic hot water systems to overcome the challenges inherent in traditional manual balancing methods.

This year, ThermOmegaTech is celebrating this milestone.

PHCP Pros recently spoke with Tom Ruggierio, Director of Sales for Commercial Plumbing at ThermOmegaTech and the subject matter expert on thermostatic balancing valve technology and the CircuitSolver thermostatic balancing valve.

CS Angled 1500x884 RBG 300x177 - In the News: PHCP Pros Q&A with Director of Sales for Commercial Plumbing, Tom Ruggierio

PHCP Pros: Who proposed the idea of the thermostatic balancing valve?

Tom Ruggierio: A plumbing sales rep in Texas named Bob Anderson presented the concept of using thermostatic technology to balance domestic hot water systems. That was the genesis of this product.

PHCP Pros: How does CircuitSolver differ from manual or pressure-independent balancing valves?

TR: The manual balancing valves and the pressure-independent valves are both flow devices; the challenge is determining how much flow is required in a branch or riser to offset the heat loss. Building engineers constantly try to determine how much flow they need to cancel the heat loss by manipulating the manual balancing valve or selecting specific flow cartridges with pressure-independent valves.

Two characteristics separate CircuitSolver from the other types of balancing valves. First, it is inherently a temperature device solving a temperature problem. The other two devices are flow devices trying to solve a temperature problem indirectly. Second, CircuitSolver is dynamic, continuously changing the flow rate to maintain a constant temperature. The other types are fixed devices; once you set them, they do not react to changing conditions that may require re-balancing.

PHCP Pros: How does CircuitSolver address the temperature loss problem?

TR: With temperature loss, you’re trying to figure out how much flow you need in a branch or riser. The higher the flow rate, the faster that water will get from point A to point B. CircuitSolver will dynamically adjust the valve’s position to increase or decrease the flow as required to offset the heat loss and maintain a constant temperature.

PHCP Pros: ThermOmegaTech is celebrating CircuitSolver’s 10-plus years of active use in the plumbing and construction industry. How has CircuitSolver evolved over the years?

TR: We have enhanced the product by adding different features based on the feedback from engineers and contractors. We added an integrated union and check valve to CircuitSolver about five years ago. Combining these elements into one valve provides a solution with a better cost-benefit and a more integrated solution with fewer leak points.

In addition, we started creating assemblies with ball valves, strainers, and thermometers, providing temperature measurement capability to the CircuitSolver. We also added several different types of end connections.

Engineers and contractors prefer these assemblies because the trades are hurting for qualified plumbers. Having these assemblies already premanufactured and tested at our Bucks County facility gives the engineer the comfort that when they specify the solution, it will be installed as they designed it; contractors like it because they don’t need to worry about leaks in the assembly.

PHCP Pros: How many variations of the CircuitSolver are out there?

TR: The basic CircuitSolver, which has no union or check valve, ranges from 1/2 inch to 2 inches. The CircuitSolver with the union and check valve comes in 1/2-inch, 3/4-inch, and 1-inch sizes. The assemblies are combined with our union and ball valves with optional strainers and thermometers; all those can be combined with different end connections.

There are a large number of combinations. The enhancements we’ve added over the last ten years result from us listening to the plumbing community and responding to their needs.

PHCP Pros: What’s the latest evolution of the CircuitSolver?

TR: Within the last year, we released a CircuitSolver thermostatic cold water balancing valve used for balancing cold water in domestic water systems.

This product is still in its infancy but has been installed in several VA hospitals to recirculate cold water. This reverse-acting valve works the opposite of a hot water valve because it starts closing its position based on cooling water. Recirculating the cold water in the system eliminates stagnant lines and helps mitigate Legionella and other waterborne pathogens that can develop in the plumbing system, creating health risks.

It also helps keep chlorine distributed throughout the system since the chlorine can start dissipating if it’s not recycled throughout the cold water, and it keeps the temperature of the system more uniform.

PHCP Pros: What would you tell someone specifying a large building on why they should use the CircuitSolver?

TR: Compared to other balancing valves, this system is automatically balanced based on the water’s temperature.

Imagine having a large hotel or a hospital with up to 200 balancing valves. To try and manually balance the system and do it correctly, as well as be able to react to system changes, would be a daunting task. CircuitSolver does it effortlessly. In addition, it eliminates callbacks, which contractors generally think is its most significant advantage.

CircuitSolver is the best solution for anyone challenged with trying to balance a hot water system with a large number of balancing valves. That’s what contractors like about it; they install it and walk away, and the system balances itself within a few hours.

PHCP Pros: Reflecting, what has the uptick been for this technology?

TR: The plumbing industry is very conservative and unwilling to make changes, so you can imagine what it was like when we introduced this new technology ten years ago. We were a new company in the plumbing industry. We had a lot of resistance from plumbing engineers to try our CircuitSolver because it was an unproven technology for balancing domestic hot water systems, which is understandable.

The primary way we got our start early on was strictly out of desperation! There would be situations where people had hot water issues and couldn’t balance the system. They tried all different types of things — changing pumps, water temperature, rebalancing, and rebalancing — to no avail.

They turned to the internet and Googled balancing valves. CircuitSolver appeared in their search. By that point, they were willing to try anything. So, after speaking with us, they tried CircuitSolver, which proved successful. That’s how we started building our success — one installation at a time.

It’s how we overcame the resistance from the plumbing industry to try new technology. Now, our thermostatic balancing valves are the solution of choice when balancing hot water systems.

PHCP Pros: How does CircuitSolver comply with codes or standards?

TR: CircuitSolver has NSF 61 certification. Most states mandate that components used in domestic hot water systems have NSF 61 certification. This certification covers two significant areas: having metal components within the valve that have low/no lead, such as stainless steel, and ensuring that other types of components used in the valves, such as plastic parts, O-rings, and sealants, will not leach harmful chemicals into the potable water system.

This past year, we worked with IAPMO and ASSE to create a thermostatic balancing valve standard. We’re working to get that standard into code to be mandated. It is a big step for the industry, which presently has no standards for any balancing valves. Our goal is to keep everyone safe and comfortable.

PHCP Pros: Is there anything you’d like to add?

Tom Ruggierio headshot1 238x300 - In the News: PHCP Pros Q&A with Director of Sales for Commercial Plumbing, Tom Ruggierio
Tom Ruggierio, Director of Sales for Commercial Plumbing

TR: I want to thank those in the plumbing community for their confidence in our products over the past 10-plus years. We have loyal customers who were naysayers ten years ago; now, they won’t use anything else but CircuitSolver.

We’re very grateful for all the effort our sales reps have put in to help promote this innovative solution and for the engineers and contractors who adopted our CircuitSolver products and used our thermostatic balancing valves religiously.

We thank you!

New E-Commerce HQ Install CSUAS for Hot Water on Demand

Joe Sargent, Onsite Plumbing Superintendent of W.E. Bowers of Beltsville, Maryland, recently completed a project where he installed CircuitSolver balancing valves in the hot water recirculating system of a large e-commerce company’s headquarters in Arlington, Virginia. This new construction project began in June 2020 and consisted of two 22-story office buildings. The first phase of the project opened to the public earlier this year.

“I chose CircuitSolver valves because of the ease of installation and the lack of maintenance needed for this product,” Sargent explains. “We installed around 70-80 CSUAS.”

AdobeStock 342515250 breaking fround for ecommerce site 300x200 - New E-Commerce HQ Install CSUAS for Hot Water on Demand
The site for the new e-commerce HQ2 in Arlington, Virginia.

The CircuitSolver® Union Assembly with Strainer (CSUAS) features a union with an optional check valve built into the body of the CircuitSolver, particulate filter, and isolation ball valves on either side to reduce the number of system components to be installed and minimize potential leak points.

“I like that they come fully assembled, so there’s not much that my guys or I have to do to install them in-line in the piping,” he says.

Sargent explains that the valves were installed quickly and balanced the system quickly. “Once the rough-in was done and all the equipment was energized, we could circulate hot water immediately,” he said. “They eliminate extra work, extra time, and extra walking around and coordination. I haven’t had any problems with them at all; it’s hard to mess up. Just look at the direction of the flow.”

Before using CircuitSolver balancing valves, he and his team would have to wait for the water balancers to go to every location and balance the circulating water. Now, they can skip that step of the process.

About eight years ago, Sargent learned about CircuitSolver when he first saw them in a water piping submittal. He now recommends them due to their ease of installation, plus lack of maintenance.

“I have installed them on my last three projects in the past eight years. I would recommend CircuitSolver to anyone who wants to listen to me! They won’t be disappointed. Once they are installed, there will be no reason to go back to them for maintenance,” he notes. “CircuitSolver eliminates the amount of work you must do in the field.”

Drain Tempering Case Study: California Laboratory Remodel

A three-story pharmaceutical laboratory in La Jolla, California, underwent a complete remodel in 2017. The rooftop HVAC unit was replaced, and humidification was required, which presented the need to cool the drainage water.

Lab image AdobeStock 616453370 300x200 - Drain Tempering Case Study: California Laboratory Remodel

“The roof was constructed oddly. Due to where the drain had to terminate, we had minimal fall to work with,” said Ed Parisi, Plumbing Design Manager at ICS (Industrial Commercial Systems), the contractor on this project.

“I had to get on the roof of the building to see what conditions we had to deal with. It was tough logistically to get the slope from the unit to the receptor; we had about eighty feet to travel.” Parisi needed an eighth of an inch per lineal foot to complete the drainage and had about nine and a half inches of fall available.

“We had been using typical devices for cooling humidifier drain water. Some had a tank or odd configurations, but none would fit correctly.” Parisi notes. He needed a better solution.

Parisi was previously introduced to the CircuitSolver product line by Chrissy Hamm of Specification Sales in Southern California. When Parisi was investigating other drainage devices, she suggested the DTV (Drain Tempering Valve). This was Parisi‘s first time using a DTV from ThermOmegaTech. “I didn’t even know it was available!” he said.

“Because [the DTV] just slips into the bottom of the pipe, it made it easy to overcome the lack of fall. Previously, there had been no device for the condensate drain for the steam humidifier at this location. The DTV worked perfectly because it’s such a compact installation. The DTV fits into a tee with the sensor probe extending into the drain flow at the bottom of the drainpipe,” says Parisi.

“The compactness of the DTV makes it a good solution. The technology is more complex but a simpler installation,” said Hamm.

Parisi’s team installed three Drain Tempering Valves for this project. “We installed one DTV on the roof and one in the first-floor laboratory ceiling for a humidifier with limited fall. A DTV was also installed for the lab’s autoclave in their wash/wear room,” he said.

The whole renovation project took about a year. “It was very complex, with eleven different piping systems,” he explains. “The three DTVs worked well. The lab had no issues with drain water that would have been too hot for the drainage piping systems,” Parisi says.

Parisi was very fascinated by this Drain Tempering Valve. “It is one of those valves nobody else would appreciate without understanding the simplicity of this solution and installation,” Parisi explains. “…the DTV is our automatic solution for these systems.”

Compared to other options on the market, Parisi says ThermOmegaTech’s DTV is his favorite. “Their products are first class, extremely reliable, well-engineered, and well-manufactured.”

“I would recommend the DTV for the ease of installation and the lack of needing special conditions (like extra space) or other equipment. [You can] thread it into the drainpipe, connect the water supply, and it’s complete,” Parisi added. “The availability and convenience of getting the product from ThermOmegaTech are also well appreciated.”

Case Study: A Magical Castle Comes to Life With the Help of CircuitSolver

Deep in the heart of Southern California, there resides a castle. At the LEGOLAND® Castle Hotel at LEGOLAND California Resort, 250 deluxe LEGO Castle rooms with themes like Knights & Dragons, Royal Princess or Magic Wizard host many visitors from far-off lands, and CircuitSolver had a hand in delighting children of all ages.

Hotel at LEGOLAND® California Resort (Image via LOCK + LAND, Chip Litherland for LEGOLAND®)

At this magical 3-story hotel in Carlsbad, California, Ed Parisi, Plumbing Design Manager at ICS (Industrial Commercial Systems) installed CircuitSolvers in this construction project. “At ICS, CircuitSolver is our standard balancing valve for all projects,” Parisi notes.

The 250-room hotel is a U-shaped building and required exactly 99 3/4″ CSUA CircuitSolvers. ICS ordered these through Todd Pipe (now Reece) in San Diego.

“This is a typical installation with the CircuitSolvers installed at the end of each DHW branch before it ties into the circulating main,” Parisi says. “In this project, the furthest CircuitSolver was approximately 650 feet of piping away from the Mechanical Room.”

In the LEGOLAND® Castle Hotel, the domestic hot water mains followed the 1st floor corridor through the building and the branches served two or three-story stacks of rooms throughout the building.

“Time to tap, I have never seen a building so consistently deliver hot water that fast!” Parisi explains. “I’m impressed with the whole system.”

“Ordering the assembled CircuitSolvers allowed ICS to use less jobsite manpower and also enabled us to install every balancing valve correctly. There were no leaks, and I never had a callback during the warranty period. Nothing but hot water!” he says. “It’s a pleasure to use.”

“ICS used a Grundfos Magna3 circulator pump with an ECM motor set for proportional pressure control. This pump used with the CircuitSolvers provided an extremely efficient circulation system. The commissioning agent complimented the Domestic Hot Water System saying that he had never experienced a system with such consistently low “time to tap” readings. The owner’s maintenance supervisor also complimented the system,” Parisi explains.

The LEGOLAND® Castle Hotel project was completed in April of 2018 and was open to the public that same month.

Parisi was introduced to CircuitSolver in 2012 by Chrissy Hamm from Specification Sales in Ontario, CA. “Chrissy guided me through my first couple of orders and I have only ordered CircuitSolvers since then.

“CircuitSolvers are the premier balancing valves available. Reliable, stainless-steel construction, variable temperature settings available, and all the necessary components to satisfy the most stringent specifications and details. All that plus no manual setting required makes CircuitSolvers a great solution,” he says.

ThermOmegaTech Launches Exciting New Video Featuring How CircuitSolver Drastically Changed the Plumbing Landscape

CircuitSolver, a brand of ThermOmegaTech®, is excited to launch its newest Talking With TOTs video. Director of Sales for Commercial Plumbing Tom Ruggierio is featured as the subject matter expert on the inner workings of this thermostatic balancing valve.

ThermOmegaTech® is a leader in the design and manufacture of self-actuating thermostatic temperature control technology. Using their trademarked Thermoloid wax actuator, CircuitSolver® continuously monitors the water temperature and automatically adjusts flow as conditions change to send hot water where needed to accommodate demand variations.

“CircuitSolver thermostatic balancing valves have been installed into thousands of domestic hot water recirculation systems since their introduction to the market in 2012,” says Ruggierio, “This year we are celebrating CircuitSolver’s 10 years of active use in the plumbing and construction industry!”

A Temperature Solution to a Temperature Problem

WEB CSCutaway left 300x236 - ThermOmegaTech Launches Exciting New Video Featuring How CircuitSolver Drastically Changed the Plumbing Landscape

Balancing a Domestic Hot Water System (DHWS) has used the time and energy of many contractors manually balancing and rebalancing to achieve the required flow needed to obtain the same temperature in each branch.

Requiring no power source, CircuitSolver® balances a system based solely on temperature as opposed to pressure or flow.

“During the start-up of a hot water recirculation system, the valve is wide open and will gradually close once the system temperature requirements are met. The valve remains in its closed position to keep hot water in the line, opening as needed when the water temperature drops below the valve’s set-point,” Ruggierio explains. “It takes away a lot of headaches.”

This allows a system to be initially balanced in hours, not days, and to stay balanced even as conditions change. To prevent deadheading the recirculation pump, the valve never fully closes, always allowing a small bypass of flow to the return.

Benefits of Recirculating Cold Water in VA Facilities to Discourage Legionella Growth

Legionella in Non-Recirculated Cold Water Systems

Stagnant, warm water in a plumbing system increases the risk of Legionella bacteria growth. In cold water systems, adequate flow through high fixture usage and low water temperatures discourage the growth of Legionella and other biofilms. However, in the event flow throughout the system or part of the system is insufficient, standing water can drastically increase the likelihood of bacteria colonization.

When cold water flow is minimal or stopped altogether, as seen during the recent COVID-19 lockdowns that left buildings unoccupied for long periods of time, disinfectant levels evaporate, and temperatures gradually rise in the Legionella growth range, leading to bacteria colonization and uneven free chlorine distribution throughout the system.

Legionella bacteria causes Legionnaires’ disease, a type of pneumonia infecting the lung. People can get sick when they breathe in water droplets or accidentally swallow water containing Legionella.

The CDC says Legionella grows best in a building’s cold water distribution system within a specific temperature range of 77°F-113°F (25°C-45°C). Cold water temperature throughout the system should be maintained at or below 77°F (25°C) to the greatest extent possible to inhibit growth.

CSU CW 1521X685 CMYK 300x135 - Benefits of Recirculating Cold Water in VA Facilities to Discourage Legionella Growth
CircuitSolver® Union Cold Water Balancing valve.

To discourage Legionella bacteria growth, cold water systems need to be recirculated. They must be balanced appropriately to establish continuous flow and keep line temperatures below 68°F (20°C), the point at which Legionella can begin to colonize.

The Veterans Health Administration (VHA) aims to prevent the spread of healthcare-associated Legionella disease and scald injury from water systems in VHA buildings where patients, residents, or visitors stay overnight with the VHA Directive 1061(1).

The directive states, “The use of piping system insulation, automatic drain devices, and recirculation to limit the rate and duration of an increase in cold water temperature in combination with appropriate biocide levels can be effective at preventing Legionella growth.”

The Need for Dynamic Balancing

In order to achieve stability, system balancing must be dynamic – continually addressing the ever-changing conditions. Thermostatic balancing valves adjust dynamically, providing the best opportunity for sustainability and Legionella mitigation. Traditional manual balancing valves could provide a solution to cold water balancing, but their static operation inherently does not factor in nor adapt to the realities of everyday system operation & changes, which may render the balancing obsolete over time.

CircuitSolver® Union Cold Water (CSU-CW) Balancing valve will automatically keep cold water moving and maintain water quality, reducing stagnation and the growth of bacteria.

Utilizing our proprietary thermal actuator as the controlling element, the valve should be installed at the end of each branch or riser in a cold water recirculation system. It will modulate open or closed in response to the water temperature to maintain a specified temperature in the line.

The CSU-CW valve features a union with an optional check valve built into the body of the CircuitSolver® to reduce the number of system components installed and minimize potential leak points.

CSU-CW benefits:

  • Stainless Steel, which is highly resistant to scaling in high mineral content environments
  • High thrust actuator keeps orifice free of debris
  • Union with integrated O-ring for a leak-free seal
  • Keeps water temperature in branches/risers evenly distributed, minimizing heat gain
  • Never fully closes, some water always passing through
  • Provides even distribution of residual chlorine levels

These systems have become more prominent in VA hospitals because of the VHA 1061(1) directive; however, any commercial building such as schools, hotels, high-rise, and multi-family apartment buildings can benefit from implementing a cold-water recirculation system to protect the water lines from the risk of bacteria colonization during periods of low flow or non-use.

Watch how it works and see how the CircuitSolver® Union Cold Water thermostatic balancing valve automatically and continuously balances your cold-water recirculation system to discourage Legionella bacteria colonization and reduce stagnation.

Eric McTee of ME Engineers, Inc in Boulder, Colorado 

As a Project Manager at ME Engineers, Plumbing Designer Eric McTee, CPD, is responsible for all aspects of a plumbing system’s design for new constructions and remodeling projects. In domestic hot water recirculation systems, McTee specifies CircuitSolver® thermostatic balancing valves. “I try to have CircuitSolver specified on as many jobs as possible due to its simplicity of it,” states McTee.

Some notable projects where he specified CircuitSolver® are the Laurel Cherry Creek Condominiums in Denver, the Broomfield Service Center, the Tupelo Honey Cafe in Denver, and Lucky Strike Bowling Centers in multiple locations.

McTee, an ASPE Denver Chapter member, first learned of CircuitSolver® from a manufacturer’s representative in 2014. “Straight from the beginning, I liked how it was a simple product that makes balancing a domestic hot water recirculation system really easy; it’s easy for the contractor and easy for the owner,” McTee says. “You install the CircuitSolver®, set it, and forget it. You do not have to worry about the system accidentally being knocked out of balance. I enjoy having a product that allows the system to work seamlessly,” McTee states.

McTee points out that once installed, the system is balanced. There is no way for the owner or a maintenance worker to adjust the valve accidentally and then need to call a balancing contractor to get the system back in line. “That is the number one cause of hot water circulation failures that I have seen,” states McTee.

“The initial cost of the CircuitSolver® is a little higher than a traditional balancing valve, but installation is faster and cheaper.

The system is already balanced and does not require a balancing contractor. [With CircuitSolver®,] you get a better-performing system that you do not have to worry about,” McTee emphasized.

“Any owner planning to hold onto a building for a long time needs to look past the initial cost and look at life-cycle cost. CircuitSolver® would save them money in the long run.” McTee typically specifies the CircuitSolver® assemblies with check valves because it makes it super easy for the contractors to install.

When asked what he likes most about these balancing valves, McTee said, “Compared to manual balancing valves, it is just a superior product. You will get better performance and system longevity out of it since you do not have to worry about rebalancing in the future. I really like the valves…because it makes [the system] easy to control. It is a product I will continue to specify for the rest of my career.”

See the Comparable Cost Savings of Thermostatic Balancing Valves vs. Manual Balancing Valves

When balancing a Domestic Hot Water System (DHWS), the goal is to ensure hot water is consistently available at every fixture throughout a building on-demand.

Circuit Solver Diagram 01 242x300 - See the Comparable Cost Savings of Thermostatic Balancing Valves vs. Manual Balancing Valves

This can be difficult with manual balancing methods, which can deplete time, money, and labor resources.

Multiple contractors must manually balance one valve at a time, often revisiting the same valve several times to adjust for inadequate flow or temperature throughout the system.

The manual balancing process is both laborious and time-consuming. In the end, it may still result in future callbacks as system demands evolve because they cannot react to dynamic changes in the DHWS.

In comparison, thermostatic balancing valves like ThermOmegaTech’s CircuitSolver® valves use thermal actuator technology to automatically and continuously adjust flow through a domestic hot water recirculation system.

These self-actuating valves are installed at the end of each branch or riser before the return line to monitor the water temperature and will modulate open and closed to maintain a set temperature in each supply line.

How CircuitSolver® Thermostatic Balancing Valves Operate:

During the initial start-up of a DHWS, the valves are wide open and will begin to close once the system temperature requirements are met. During post-startup operation, each valve operates independently, establishing flow as needed to meet the system’s variable hot water demands throughout the day.

The valves will never fully close, always allowing a small amount of bypass of flow to the return to avoid dead-heading the recirculation pump during low usage.

CircuitSolver® is a temperature device that solves a temperature problem.

CSU Banner 300x120 - See the Comparable Cost Savings of Thermostatic Balancing Valves vs. Manual Balancing Valves

Through this entirely hands-off method, a DHWS using CircuitSolver® valves is balanced in a short time and can dynamically adapt to evolving system needs.

Compared to these thermostatic balancing valves, manual valves are simplistic, antiquated, and produce high labor costs.

The Savings

We surveyed plumbing contractors nationwide on domestic hot water system balancing costs and determined that CircuitSolver® thermostatic balancing valves generate significant cost savings by eliminating manual balancing labor.

The survey collected data on total costs associated with balancing a system, including labor time, employee salaries, required contractors per job, frequency of callbacks, and materials used. Below are the findings on the average cost of balancing the DHWS of a 10-story building.

The Opportunity

Cody Cline, Vice President of GW Mechanical, had the opportunity to use ThermOmegaTech’s thermostatically controlled Drain Tempering Valves (DTV) in the new construction of the Wyoming Life Resource Center in Lander, Wyoming.

These Drain Tempering Valves (DTVs) are typically used in applications where a high-temperature discharge flow to a drain or sewer must be tempered with cold water to meet plumbing code requirements and prevent PVC piping damage due to over-temperature conditions.

“This healthcare facility has 14 separate buildings where we used the drain tempering valves (DTVs)” said Cline. “All the buildings have commercial dishwashers [installed] underneath the counters because we are working with limited space, [all the DTVs were] installed within cabinetry underneath the kitchen sinks.”

Each new building has one commercial dishwasher with discharge flow to a drain that needs to be tempered down; therefore, one DTV was installed in each location.

The Installation

“We had used [DTVs] on another application, and we liked it because we could modify the piping to work for the application. For this installation, I think [the engineer] chose [DTV] because it was so small and had to fit under the counter, in a very limited space,” explained Cline. “I would have chosen these DTVs anyway because it is the right application for the space.”

The dishwashers’ discharge temperature is 180 (degrees) Fahrenheit, so the water needed to be cooled down before reaching the PVC piping underground to comply with the plumbing codes.

The DTVs installed had a set point of 120 (degrees) Fahrenheit. These valves will automatically open to allow the injection of cold water to temper down the discharge fluid before it reaches the drain if the valves sense fluid temperatures above 120 (degrees) Fahrenheit.

The Result

“In this specific job, the DTV sped up the process because of its size and adaptability to that space. It made it easy. Other than that, the only way I know [how to temper the water is by] using a drain cooler. Drain coolers are big and bulky, you need the space to put them in, and there are more requirements,” Cline mentioned.

When asked what advantages the DTV has compared to other options on the market, Cline said, “Size and simplicity.” DTVs are small, have minimal moving parts, and are easy to maintain.

“It comes down to space and the fact that [the DTV] is mechanical; there are no moving parts, which is nice. There is nothing really to maintain,” said Cline.

“I recommend the product for functionality and space requirements. The DTV works great,” said Cody Cline, Vice President of GW Mechanical.

CircuitSolver® to Release Brand New Thermostatic Cold Water Balancing Valve at AHR

Warminster, PA – ThermOmegaTech: CircuitSolver, a ThermOmegaTech brand, announced its CircuitSolver Cold Water Balancing Valve (CSU-CW) this month, and will be displaying the valve with a live demo at the AHR tradeshow in Las Vegas from January 31st to February 2nd. The CSU-CW is a dynamic valve designed to automatically balance cold water recirculation systems utilizing the same reliable and precise thermal actuator technology as the original CircuitSolver for balancing recirculating hot water systems.

This unique valve will effectively mitigate the risk of Legionella bacteria growth in a domestic cold-water system (DCWS) by continuously monitoring water temperatures and modulating flow to maintain a set temperature at the end of each branch or riser. This automatic response to water temperature balances the cold water throughout the system, reduces stagnation, and ensures “residual chlorine” is distributed throughout the system.

“Every day, the topic of Legionella mitigation is becoming more frequently discussed within the plumbing industry.” Tom Ruggierio, National Business Development Manager at ThermOmegaTech, says. “For domestic water systems, most of the focus has been on the hot water portion. However, over the past few years, the Veterans Health Administration (VHA) has taken a more proactive approach in addressing Legionella mitigation in domestic cold-water systems.”

To achieve stability, ThermOmegaTech’s engineers have worked diligently to develop a dynamic design that continuously addresses the ever-changing conditions often associated with cold water systems, including changes in building occupancy, building expansion, reduction in utilization, and other variables that may disrupt the balance of a system.
CSU CW - CircuitSolver® to Release Brand New Thermostatic Cold Water Balancing Valve at AHR
The Covid-19 pandemic has impacted the plumbing industry in many ways and domestic cold-water systems have been a weak point in many buildings. “Reopening buildings found that their unbalanced cold-water systems had sat stagnant and warmed, leading to dangerous Legionella bacteria growth,” Ruggierio comments. “The CircuitSolver Cold Water valve automatically balances the DCWS and mitigates Legionella risk”.

Case Study: University of South Florida Fixed Hot Water Wait Times & Saved BIG

USF Email Header 3 - Case Study: University of South Florida Fixed Hot Water Wait Times & Saved BIG

INSTALLATION SITE OVERVIEW

University of South Florida (USF)

The USF is a public university with its main campus located in Tampa. About 10% of the school’s almost 40,000 undergraduate students live in one of the 44 on-campus dormitories. After temporarily shutting down during the height of the coronavirus pandemic in 2020, dorms reopened to students in the Fall of 2021.

THE OPPORTUNITY

Beacon Hall, the newest addition to the university’s on-campus dormitory buildings, opened in August of 2017. A coed, six-story construction, the dorm houses 378 residents in a mix of traditional and suite-style rooms.

Since opening, the 5th-floor gang shower, which is located in the center of the floor with student rooms lining the exterior of the building, had experienced a lot of hot water issues.

Beacon Hall - Case Study: University of South Florida Fixed Hot Water Wait Times & Saved BIG

Mike Bishop, VP of Engineering at RGD Consulting Engineers stated: “Students used to turn on the showers, go to breakfast for 30 minutes, then come back to shower when the water was hot. Otherwise, they were taking a cold shower.”

A major inconvenience to students and a huge waste of water for the university, the system’s hot water demands needed to be re-evaluated.

THE INSTALLATION

After unsuccessful attempts to rectify the hot water supply and balancing issues, the developer contacted RGD Consulting Engineers.

Mike Bishop discovered that the manual balancing valves were a major roadblock in the DHW system functioning correctly due to its inability to adapt to changing system demands, and, with no question, recommended CircuitSolver thermostatic balancing valves.

Working with Spirit Group, a CircuitSolver representative in Florida, thirteen ½” CircuitSolver valves were installed at the end of each branch and one ½” CircuitSolver was placed on the return line to the water heater.

HOW THE CIRCUITSOLVER WORKS

The CircuitSolver® is a thermostatic balancing valve that automatically and continuously adjusts flow through a DHW system to maintain a specified temperature at the end of each hot water supply line. This keeps the system fully balanced with hot water available at all times and on all floors, even with variable and intermittent demands.

On startup, the system automatically balanced itself in under 3 hours, all without manual labor. “In the meantime, the plumber actually went out a did another job,” Bishop mentions, “Then they went and got breakfast, and when they came back [the DHW system] was balanced.”

THE RESULT

Since the installation of CircuitSolvers, all balancing issues in the Beacon Hall dormitory have been resolved. Students are able to take hot showers without 30-minute wait times, and complaints have ceased. Water usage has plummeted, and the extra recirculation pump was removed, effectively reducing utility usage.

As for Mike Bishop, in this balancing case study, he says that the contractor on the job reported a favorable experience. “He was ecstatic! This was his first CircuitSolver job, but he’s going to start using it everywhere.”

CircuitSolver Questions: Asked & Answered

top 5 faqs - CircuitSolver Questions: Asked & Answered

We’ve compiled a list of some Frequently Asked Questions (FAQs) regarding the CircuitSolver product line to answer your questions.

1. My lines are prone to calcium buildup; will CircuitSolver clog?
No, it won’t. The CircuitSolver actuator’s modulation is powerful enough to force out any buildup in its path, developing over 40 lbs. (18kg) of thrust, which is more than enough to break loose any mineral buildup.

Note that mineral buildup is unlikely to occur in CircuitSolver since it mainly occurs where there is a heating surface or a very small leak.

2. Does CircuitSolver shut off tightly?
No. A small leakage (0.2 GPM) is built into CircuitSolver valves even when “closed” to avoid dead-heading the distribution branches.

In some applications where the water distribution piping is occasionally chemically or thermally sterilized, the leakage allows enough of this flow through the system to sterilize the line, regardless of temperature.

3. How much does CircuitSolver cost?
Compared to traditional manual balancing methods, CirucuitSolver reduces overall costs by 44% by saving money on components and labor. See our study here.

4. Where has CircuitSolver been installed? 
All over the place! Take a look at our installation map to see where CircuitSolvers are installed near you.

5. How do you select the correct set-point for CircuitSolver?
As described in the product sheets, the “XXX” in the model number is the desired return line temperature. For example, you want the return temperature to be 110°F, and the line size is 3/4”, you would select a CS-3/4-110.

DHWS Practices: Pump Size Calculations and Other Design Considerations

To ensure a supply of hot water is provided at every fixture in a timely manner, buildings typically utilize a domestic hot water recirculation system in their plumbing design. DHWR systems are considered a best practice in commercial, multi-family, and institutional buildings, especially if designed with thermostatic balancing technology and accurate pump size calculations and other considerations, as listed in this article.

Such recirculation systems should guarantee occupant comfort, safety, and code compliance, as well as water and energy conservation.

DHWS - DHWS Practices: Pump Size Calculations and Other Design Considerations

When designed properly, a DHWS will provide adequate amounts of water at the prescribed temperature to all fixtures and equipment during all times of use while ensuring a cost-effective, efficient, and lasting installation.

How to Improve Your DHWS Design with Thermostatic Balancing Valves

Understand the Importance of Balancing Domestic Hot Water Recirculation Systems 

A DHWS needs to be properly balanced to ensure hot water is readily available on-demand, on all floors, and at every fixture.

Water is “lazy” and will flow to the path of least resistance. To ensure there is no short-circuiting and all branches have adequate hot water, a restriction point is needed to create only the flow required to offset heat loss in each branch or riser.

Typically relying on multiple branches off the hot water supply line, domestic hot water systems need a device that can respond dynamically to changing needs.

Traditional balancing valves require manual adjustment to create the flow rate needed in each branch.

Challenges associated with manual balancing:

  • Iterative and time-consuming
  • Difficult to properly set to the correct parameters
  • Static and unable to adjust to the changing conditions of a dynamic system.

DHWS are balanced when unoccupied, so “callbacks” are common to rebalance the system when the building becomes occupied.

Implement Thermostatic Balancing Valves

CircuitSolver® self-actuating, thermostatic balancing valves automatically and continuously adjust the flow of DHWR systems to maintain a specified temperature at the end of each branch.

Dynamically designed, these valves adjust in response to heat loss and demand fluctuations without the need for manual balancing, which ultimately reduces labor time and costs and eliminates hot water complaints.

Calculate Flow Rate to Offset Heat loss 

When designing a DHWS, you should calculate the flow required to offset heat loss at the system level. Balancing flow will eliminate the risk of short-circuiting.

Minimizing flow velocity should also be considered to prevent any erosion in copper piping. Erosion can occur when high water velocities and hot water mix in the copper piping.

Ensure Accurate Pump Size Calculations

Inaccurately sizing the recirculation pump in your DHWS can result in many problems that will waste time and money in the long run.

Sizing Too Small can result in not enough flow to maintain temperature throughout the system.

Sizing Too Big tends to be unnecessarily expensive due to the need for larger pumps and wasted energy. Oversized recirculation pumps can wear out copper piping and cause pinhole leaks as well.

To ensure an efficient and economic thermostatically balanced DHWS system, follow ASPE guidelines to determine the recirculation flow rate needed to offset heat loss.

For more information on recirculation pump sizing and demonstration examples of heat loss calculations, check out our Recirculation Pump Sizing Guide.

CircuitSolver Balancing Valve Passes The Hard Water Test – Yet Again

To determine the possible effects of hard water on CircuitSolver’s longevity, ThermOmegaTech has been conducting an ongoing hard water test on the same balancing valve at their headquarters in Warminster, PA since 2013.

A single valve was installed in the facility’s hard water on January 15, 2013, with its performance and appearance evaluated annually. 2021 is the 8th consecutive year that the test CircuitSolver has continued to operate efficiently, with no signs of mineral deposits, wear or fatigue in the installation.

Ongoing Effects of Hard Water Study

To determine exactly how hard the water was before the valve was installed, QC Laboratories, a certified test laboratory in Warminster, PA, analyzed collected water samples and found the hardness of ThermOmegaTech’s water to be 229 mg/L – this is considered “very hard” water.

Typical effects of hard water are often damaging and can include mineral deposits, scale buildup on plumbing fixtures, impaired flow rates, and stained appliances.

Cases of Legionnaires’ Disease Are Rising in the U.S.

Since its discovery in the summer of 1976, Legionella bacteria has been an ever increasingly hot topic in the plumbing industry, seeming to lurk in pipes and water systems, waiting to strike in a moment of lapsed attention or vigilance.

According to Smithsonian Magazine, the CDC reports that as of 2018, cases of Legionnaires’ Disease, pneumonia caused by aspirating the Legionella bacteria, have risen significantly. With nearly 10,000 cases reported in 2018 alone, Legionnaires seems to be running rampant in modern water systems.

legionnaires Report 1024x678 - Cases of Legionnaires' Disease Are Rising in the U.S.

While some attribute the sharp rise in case numbers to improved reporting, awareness, and testing methods, it has also been suggested that aging infrastructure and climate change could be contributing factors.

Read the full report here.

Reducing The Risk with System Design

While prevalent in modern plumbing systems, Legionella bacteria only presents a risk when able to colonize, typically in stretches of piping with warm, stagnant water. For many buildings, simple changes to system design and management procedures can significantly reduce the prevalence of Legionella bacteria and inhibit growth before it can begin.

1. Avoid “Dead Legs” in Piping Design
Minimizing the distance between supply lines and fixtures in your system design can reduce areas of stagnation in the hot water piping which could accumulate scale and biofilm buildup, a prime location for Legionella bacteria to set up shop.

2. Maintain Water Temperature Control
Legionella bacteria flourishes in warm water with comfortable temperatures ranging from around 70°F to 115°F. Storing water at temperatures above 120°F will generally help prevent colonization.

To prevent bacteria growth, specify hot water tanks that store water above 140°F (60°C) and use a mixing valve to recirculate it to the fixtures at 120°F (48.9°C) to comply with anti-scalding regulations.

Legionella Growth - Cases of Legionnaires' Disease Are Rising in the U.S.

3. Keep Pumps Running Continuously
Keeping your recirculation pumps running at all times will keep water flowing and prevent bacteria from grouping together and adhering to pipe walls.

4. Perform Routine Maintenance of Equipment
The CDC recommends cleaning water tanks routinely including periodically draining the system to remove scale and sediment. This will prevent biofilm, organic debris, and corrosion from contaminating your water system.

PHCP Pros CircuitSolver Feature: The Future of Balancing

CircuitSolver and thermostatic technology was featured in the PHCP Pros January issue, with three plumbing industry professionals weighing in on the future of domestic hot water recirculation system balancing technology.

Instant hot water at the turn of a tap is a luxury that many in developed countries take for granted, with little thought spared to exactly how it is available on the 50th floor.

For decades, this feat of engineering has resulted from the many hours spent manually balancing and rebalancing domestic hot water recirculation systems, often performed several times to accommodate flow as system demand evolved. While effective enough in principle, manual balancing flounders in practice, with inflated labor costs and inflexibility in the face of usage variations.

To conquer the challenges inherent to traditional manual balancing methods, ThermOmegaTech invented the CircuitSolver® thermostatic balancing valve. It automatically balances the DHWS by adjusting flow through the system to maintain a set temperature at the end of each supply branch, eliminating the need for manual balancing while ensuring instant hot water delivery to each fixture and accommodating flow to meet demand variations.

Since its debut in 2012, the CircuitSolver has been installed in thousands of domestic hot water recirculation systems throughout the United States and Canada.

ThermOmegaTech caught up with three plumbing engineers for their opinion on the valve: Joper Tupas, PE, CPD, from the Murray Co. Engineering Department, Rancho Dominguez, Calif.; Rick Sawyer from BMA Mechanical+, San Luis Obispo, Calif.; and Scott Fawkes and Michael Washburn from Architectural Resources Inc., New York, N.Y.”

Top 5 CircuitSolver FAQs

CircuitSolver FAQs

Top 5 CircuitSolver Frequently Asked Questions

To answer your CircuitSolver questions, we put together a list of some of our common CircuitSolver FAQs (Frequently Asked Questions) regarding the CircuitSolver product line. 

d4d84f58 dd4d 4331 8919 38fe931a52c8 - Top 5 CircuitSolver FAQs

1. What is the GPM when the valve is closed?
When CircuitSolver is closed it does not shut off completely and still allows a fraction of a gallon per minute flow. This allows it to better sample upstream water temperature changes, as well as better facilitate high temperature sanitizing cycles of the domestic hot water system. To determine the GPM, multiply the square root of the pressure differential across the valve by the Cv.

For example, if pressure differential is 4 psi, square root of 4 is 2, and 2 X Cv = GPM.

2. What is the full open rate of CircuitSolver?
The published Cv flow coefficient for each valve size allows calculation of the full open flow rate. Multiply the square root of the pressure differential across the valve by the Cv to get GPM. For example, if pressure differential is 4 psi, square root of 4 is 2, and 2 X Cv = the full open GPM.

3. What is the highest temperature CircuitSolver can handle?
CircuitSolver is rated to a maximum temperature of 250°F (121°C). All the valves can easily handle more than 212°F (100°C) which is the boiling point of water and higher than any water temperature in a domestic hot water system.

4. What is the pressure drop across a CircuitSolver?
The basic approximation for the pressure drop across the CircuitSolver within a given branch utilize the following equation where Cv = design Cv and flow is the estimated flow to offset heat loss in the branch:

For this example – Cv = .85 (design Cv for ¾” CircuitSolver)
Flow = 1 GPM (estimated flow to offset heat loss in a given branch)

ΔP = [GPM/Cv]2  = [1/.85]2  = 1.4 psi

5. Is there a warranty offered with the valve?
Yes, the CircuitSolver product line offers a 3-year warranty.

Balancing Cost Savings with CircuitSolver®

Balancing Cost Savings

Don’t Pay More When You Can Pay Less!

Traditional manual balancing is labor-intensive and time-consuming, requiring several contractors to balance one valve at a time, often revisiting valves over and over to adjust for inadequate flow or temperature. Due to this, manual balancing inevitably leads to hefty labor costs and frequent callbacks to accommodate for the changing demands of a dynamic system.

The CircuitSolver® Solution

The CircuitSolver® thermostatic balancing valve automatically adjusts flow through a domestic hot water recirculation system to maintain a set temperature at the end of each supply branch.

Dynamic and self-modulating, CircuitSolver® balances a system in minutes and automatically directs hot water where it is needed, dynamically adjusting to satisfy changing system needs. CircuitSolver® effectively eliminates the need for manual balancing labor and callbacks, saving a substantial amount of time and money.

Cost Savings

In the Spring of 2020, CircuitSolver® conducted a nationwide survey of plumbing contractors to quantify the cost savings of replacing manual balancing valves with the CircuitSolver® thermostatic balancing valve. Data was collected on total costs associated with balancing a system including total labor time, employee salaries, required contractors per job, frequency of callbacks, and materials used.

The survey concluded that, when directly comparing the total manual vs. thermostatic balancing costs of a 10-story DHWS, implementing the CircuitSolver® balancing valve would reduce total costs by 44%. Click here to see the balancing cost savings calculations!

Instead of implementing an army of traditional hot water heaters to supply the sprawling facility, IUSMQ’s water supply is heated by a hospital-owned power plant and distributed throughout its wings and floors.

To account for the heat loss that occurred as the hot water traveled through the building’s long recirculation lines, the power plant had to intentionally “overheat” the water being delivered to IUSMQ.

However, as a result of new standards and regulations, the hospital was required to adjust the temperature of incoming water to a safer level.

According to the building’s consultant, André Renaud, this resulted in the hospital experiencing a lack of hot water in some areas.

The Installation

Renaud initially reviewed the recirculation system to determine the fixed flow rate needed to offset heat loss and consumption. According to his calculations, the main recirculation piping would not be able to withstand the high flow rate required due to the risk of premature erosion of the copper piping.

Due to this, the consultant chose to replace the system’s fixed flow valves with 108 CircuitSolvers. sizes 300x131 - Case Study: CircuitSolver Install at the Mental Health Institute of Quebec
Installed in-line, CircuitSolver is a self-actuating, thermostatic recirculation valve that automatically and continuously adjusts flow to maintain a specified temperature at the end of each domestic hot water supply line.

CircuitSolver bases dynamic flow rates solely on fluid temperature, easily accommodating for passive system heat loss and demand fluctuations, with no need for re-balancing.

By switching to the CircuitSolver, Renaud eliminated the labor and guesswork associated with the manual balancing of fixed flow valves.

The Result

After a quick and easy install and almost instantaneous automatic balancing, hot water is now available throughout the entire main pavilion on demand.

Code Compliant DTV – Simplify By Plumbing For Compliance

As a component of their normal operation, commercial equipment such as dishwashers, combi ovens, and steam humidifiers discharge superheated steam and water. This effluent needs to be tempered down before going to the drain and entering public sewers.

ThermOmegaTech® offers the drain tempering valve (DTV) to simplify this process and comply with drain temperature limitations of international plumbing codes.

See some FAQs about the DTV below.


bd33d443 ac22 4ea3 ae49 9694fdbd4e07 1024x410 - Code Compliant DTV - Simplify By Plumbing For Compliance

FAQ #1: When should the DTV be used?

A DTV should be used in any application where drain effluent with temperatures exceeding 140°F must be cooled prior to entering a public sewer in accordance with plumbing codes.

Failure to comply with these temperature limitations may lead to failed inspections, fines, and damage to PVC piping or equipment.

FAQ #2: How does the DTV work?

The DTV is installed into the drain line so that the hot effluent passes over the thermostatic actuator to constantly monitor drain water temperature. When effluent temperatures rise above the valve’s set-point, the valve will automatically modulate open to allow cold water to flow into the drain, cooling the effluent.

Once the effluent’s temperature falls below the set-point, the DTV modulates closed, cutting off cold water flow to conserve water.

FAQ #3: Can the DTV handle steam?

Yes, the DTV can handle fluid temperatures up to 250°F.

FAQ #4: What sizes are available?

The DTV is offered in 1/2″, 3/4″, and 1″ sizes in both brass and stainless steel.

Guaranteed Drain Effluent Compliance with the DTV

Guaranteed Drain Effluent Compliance with the DTV

Temperature is often a subjective experience – how cold is jacket weather, how hot is too hot for a shower, etc.

What is never subjective? Drain effluent temperature restrictions.

Drain water from commercial equipment exceeding the 140°F cut-off point can significantly impact a business’ operations due to failed inspections, fines, and damaged PVC piping.

To simplify compliance with international plumbing codes governing effluent flow, ThermOmegaTech offers the drain tempering valve (DTV). Compact and effective, the DTV is 100% self-operating and is incredibly easy to install on new or pre-existing commercial equipment set-ups.

DTVs2 1024x410 - Guaranteed Drain Effluent Compliance with the DTV

The DTV is installed into the equipment’s drain line so the hot effluent flows over the valve’s thermal actuator, with a cold water supply on the valve’s inlet. While there, the DTV continuously monitors effluent temperatures.

When the effluent’s temperature reaches the DTV’s set-point, the valve will automatically open to mix in cold water and temper down the effluent into compliance range.

Once the effluent temperature has fallen to the DTV’s set-point, the valve will shut off the cold flow to conserve water.

Installation Site Overview

Inspira Health operates a variety of healthcare facilities throughout southern New Jersey, including Inspira Health Center Mullica
Hill Commons in Mullica Hill, NJ.

Opened in November of 2019, the 5-floor Mullica Hill Commons facility is a state-of-the-art general medical and surgical center, featuring specialized obstetrics and gynecology services.

inspira mullica hill medical center outisde 1 750xx4576 2574 434 0 300x168 - Case Study: Inspira Health CircuitSolver Installation
Inspira Health Mulica Hill Commons


The Opportunity

A new construction, Mullica Hill Commons’ contractors relied on the expert advice of the design engineers to specify products that would meet the needs of a dynamic healthcare DHWR system. The CircuitSolver® Union Assembly Strainer (CSUAS) balancing valve was specified at 140°F to satisfy the design’s hot water requirements and reduce installation time. The CSUAS comes preassembly with the CircuitSolver® thermostatic balancing valve with an integrated union, two ball valves on either side and an integrated strainer.

 

The Installation

In accordance with the project specifications, MMC Contractors installed 102 CircuitSolver® Union Assembly Strainers throughout the system saving significant time by not having to manually install each component. CircuitSolver® valves were installed at the end of each domestic hot water branch in place of manual valves to provide a balanced system. “There was no balancing necessary because these valves are self-adjusting,” Mike Formica of MMC Contractors commented. “The CircuitSolver® is the fastest and easiest way to balance a system.”

These self-actuating, thermostatic valves automatically and continuously adjust system flow to maintain a specified temperature at the end of hot water supply line by monitoring water temperature, eliminating manual balancing as well as the possibility of callbacks for adjustments to meet changing system demands.

 

The Result

Soon after startup, the facility was supplied with hot water throughout the building without any balancing procedures. Inspira Health Center Mullica Hill Commons opened on November 8, 2019 to much fanfare and celebration and, thanks to CircuitSolver®, the staff of Mullica Hill Commons will be spending many years caring for their patients with instant hot water at the turn of a tap.

Your CircuitSolver® FAQs – Answered!

Your CircuitSolver® FAQs – Answered!

We frequently receive questions about DHWS design, CircuitSolver® applications, and our other plumbing products during calls with our representative agencies. Below are some of the most commonly asked questions:

Q1: Do you have to use CircuitSolver® with a variable speed recirculation pump?

A1: No, CircuitSolver®s may be installed in systems using standard fixed speed or variable speed recirculation pumps. However, some features of a variable speed pump, also known as a “smart” pump, can be an excellent match with CircuitSolver®s.

Q2: What happens during system start-up when using a fixed speed pump and CircuitSolver®?

A2: At startup, CircuitSolver® is fully open, therefore GPM is high and head loss is low, allowing the system to balance quickly. As water temperature rises to CircuitSolver® set-point the valve modulates “closed”, adding friction/heat loss and reducing the flow from the pump. As a result, the flow required to offset heat loss will be satisfied.

Q3: How do you size the recirculation pump in systems with CircuitSolver®?

A3: Pumps should be appropriately sized to offset total system heat loss, whether it is a fixed speed or variable speed pump. Systems should not be sized for start-up, they should be sized for normal operation of the recirculation system. The CircuitSolver® Design Guide can help you calculate flow, pressure loss, and the recirculation pump size of your system. The design guide is available on our website’s plumbing specs page here.

Q4: Can CircuitSolver® work in the same recirculation system as an aquastat?

A4: Yes, CircuitSolver® can function in systems with aquastats, however ASHRAE, ASPE, and OSHA strongly advise against turning off recirculation pumps with aquastats.

Q5: Do you have BIM and Revitt files on your website?

A5: Yes! CircuitSolver® BIM and Revitt files are available on our website’s plumbing specs page here: https://circuitsolver.com/plumbingspecs/.

CircuitSolver Case Study: Bringing An Edge To St. Elizabeth Healthcare

St. Elizabeth Healthcare operates five facilities throughout Northern Kentucky, including St. Elizabeth Healthcare Edgewood, a state-of-the-art general medical and surgical facility.

As a healthcare facility serving the larger Cincinnati metro area, there is a constant flow of patients, visitors, and medical personnel through their halls. Unfortunately, the hot water was not flowing quite so quickly. For years the hospital had dealt with an unreliable and unbalanced hot water supply. The domestic hot water system’s (DHWS) return runs were operating inefficiently, leaving some of the hospital wings completely without hot water at times.

healthcare 300x188 - CircuitSolver Case Study: Bringing An Edge To St. Elizabeth Healthcare
St. Elizabeth Healthcare

To address this problem, MarkCo Plumbing installed around 90 CircuitSolver® balancing valves in their DHWS. CircuitSolvers were installed at the end of each hot water branch in the system, replacing the manual balancing valves.

These self-actuating, thermostatic recirculation valves automatically and continuously adjusted the flow to maintain the specified temperature at the end of each domestic hot water supply line. No manual balancing was required.

After the successful CircuitSolver® installation, St. Elizabeth Healthcare Edgewood now has access to an on-demand hot water supply in all wings, on every floor, at every fixture. CircuitSolver® was able to balance the system when engineers could not.

Where manual balancing fails, CircuitSolver® delivers.

About CircuitSolver®:

The CircuitSolver® is a thermostatic, self-actuating balancing valve that continuously and automatically adjusts the flow through each branch of a domestic hot water recirculation system to maintain the specified temperature at the end of each branch, regardless of fluctuations in hot water demand. It is a direct replacement for manual balancing valves and eliminates balancing labor and callbacks.

CircuitSolver® Union Thermal Disinfection Solves Bacteriological Problems

Q&A with ThermOmegaTech® about the new automatic DHWS balancing valve – CircuitSolver® Union Thermal Disinfection

Being “first” often sets the bar high. As one of the first manufacturers of a thermostatic balancing valve for domestic hot water recirculation systems, The ThermOmegaTech® commitment has not just been to set the bar but also to raise the bar. Since the introduction of its CircuitSolver® in 2012, the company has frequently added components, including ball valves, strainers, check valves, and ProPress ends, to meet customer demand.

In April 2018, the innovation continued with the launch of the CircuitSolver® Union Thermal Disinfection thermostatic balancing valve for domestic hot water systems. The union is integrated with the valve body, which has an optional integral check valve. A vital feature of the CircuitSolver® Union Thermal Disinfection is the new capability to automatically balance a domestic hot water system during a thermal disinfection procedure.

In the following Q&A with ThermOmegaTech®, Plumbing Engineer explores the new product’s features, including its ability to mitigate Legionella and other bacteriological problems.

PE: What makes CircuitSolver® Union Thermal Disinfection different from other valves on the market?

TOT: It has all-stainless steel construction for maximum corrosion resistance and durability. It is NSF61, and NSF372 certified — even though it seems that all components in a domestic hot water system (DHWS) should be certified and most plumbing codes and specifications say they must be, not all balancing valves are certified. The valve is completely automatic, thermostatically balancing the standard recirculation temperature and the high-temperature thermal disinfection cycle. No power, signal, or powered actuators are required, as in other balancing valves.

ThermOmegaTech® design is highly resistant to mineral buildup and the adverse effects of debris in the piping system. It is the only tamper-proof thermostatic balancing valve on the market. Other competitive devices are adjustable for several reasons: those manufacturers don’t manufacture their thermal actuators as ThermOmegaTech® does. They aren’t as flexible and offer all the setpoint variations we can, so their valve is adjustable, making it prone to tampering and/or being set to a temperature other than what the designer specified.

With this valve, the plumbing system designer specifies the desired temperature, and the valves are factory-set to that exact setting.

PE: What are the benefits or special features of the CircuitSolver® Union Thermal Disinfection specific to those designing and specifying thermostatic balancing valves for DHWS?

TOT: CircuitSolver® Union Thermal Disinfection brings the benefits of the standard CircuitSolver® into thermal disinfection applications. There is no manual balancing required. It can simply be installed once the system is turned on, and within minutes the building’s DHWS is balanced. Unlike manual balancing valves or fixed-flow devices, CircuitSolver® Union Thermal Disinfection will automatically go to full open when high-temperature water is being supplied, providing maximum flow for thermal disinfection processes.

Balancing From Coast to Coast With CircuitSolver®

For nearly a decade, CircuitSolver® has exceeded the standard for balancing domestic hot water systems. The thermostatic self-actuating balancing valve controls temperature and ensures hot water is delivered consistently to all fixtures without the need for manual balancing. The simple design combined with the unique technology of the valve has transformed the future of domestic hot water balancing.

To date, there are thousands of CircuitSolver® installed in buildings across the country with more being spec’d into projects every day. More and more contractors are realizing the convenience the valve creates by eliminating the need for time-consuming and expensive manual balancing labor and equipment.

ThermOmegaTech® interviewed a few contractors to hear about their experiences using CircuitSolver®. Below are the responses from three plumbing contractors: E.M. Duggan Inc, Pan-Pacific Mechanical, and Production Plus Plumbing Inc.

E.M. Duggan Inc. – Boston, Massachusetts

Overview of the project

Founded in 1891, E.M. Duggan Inc. is a full mechanical contractor specializing in commercial plumbing, HVAC and sprinkler systems in and around Boston, Massachusetts. Stephen Thompson, who has been working for E.M. Duggan for 30+ years, talks about the recently completed Avalon North Station high-rise apartments, right next to the home of the Boston Celtics, and the installation of CircuitSolver®.

Installation

This newly constructed 38-story luxury apartment building with 537 units used CircuitSolver® to balance its domestic hot water system. The system was broken into three zones of water — low, medium, and high — and required roughly 100 Circuit Solvers.

Results

The contractor was pleased with how quickly the system was balanced. It usually takes two to three days to balance a system manually, but by using CircuitSolver®, this process was done instantly. This translated into huge savings in terms of time and effort that is usually devoted to the balancing process. There was no scaling or gumming up of the system either, which is sometimes an issue when using manual valves. They experienced no problems or call backs.

When asked how CircuitSolver® compares to other balancing valves, Thompson says, “It’s hard to compare to since there really isn’t anything else like it on the market.”

2017 September PHC Balancing Coast to Coast USC Village - Balancing From Coast to Coast With CircuitSolver®Pan-Pacific Mechanical – Los Angeles, California

Overview of the project

For 60+ years, Pan-Pacific Mechanical has been a family-owned mechanical contractor in California. Richard Parker talks about the USC Village project at University Park Campus Los Angeles, and his experience with installing CircuitSolver®.

Installation

This construction project consisted of five buildings — five stories, at 750,000 square feet a piece. Each building required 110 Circuit Solvers totaling 600 valves for the whole project.

Results

Normally it takes a long time to balance a system. A project this size would take three or four plumbers per building at least two weeks to get the system perfectly balanced. With CircuitSolver®, the contractor was able to start up the system, and it was balanced automatically.

This saved them both time and money, plus made the whole process easier. They have had to make zero adjustments and haven’t had any clogging issues that can be a problem when using other valves. Since CircuitSolver® automatically adjusts to the changing water temperatures, the system doesn’t becomes unbalanced and hot water will be at the branch when you need it, so there won’t be any long wait times.
