How CircuitSolver Valves Work
Traditional manual balancing valves often fall short of meeting the dynamic hot water needs of domestic hot water recirculation systems. Manual balancing is typically achieved by combining the efforts of several contractors balancing and re-balancing the system over and over to achieve the required flow in a static environment during start-up. This balancing process results in hefty labor costs and frequent callbacks as the dynamics of system usage render the initial balancing inadequate.
While manual balancing methods are good in theory, they flounder in practice. Inflated labor costs and the inability to react to dynamic changes in the Domestic Hot Water System (DHWS) highlight these inefficiencies.
Thermostatic Balancing – Install it and Forget it!
To conquer the challenges inherent to traditional manual balancing methods, ThermOmegaTech® invented the CircuitSolver®, the market’s first thermostatic balancing valve. The CircuitSolver® automatically balances a 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.
Using our patented Thermoloid® blended paraffin wax actuator, the CircuitSolver® continuously monitors the water temperature and automatically adjusts flow through the system to send hot water where it is needed to accommodate demand variations.
Installed in-line at the end of each branch before the return, the CircuitSolver® utilizes a thermal actuator to modulate the valve open and closed in response to temperature variations to control water flow through the CircuitSolver®. When the water temperature falls below the valve’s set-point, the CircuitSolver® modulates open to allow more water to flow to the return. As the water approaches the valve’s set-point temperature again, the CircuitSolver® automatically modulates towards its closed position.
During the initial start-up of a DHWS, this modulation will allow additional flow to the branches still in need of hot water, ensuring a thermally balanced system. During post-startup operation, each valve operates independently, establishing flow as needed to meet the system’s variable hot water demands throughout the day. To avoid dead-heading the recirculation pump during times of low usage, the valve will never fully close, always allowing a small amount of bypass flow to the return.
CircuitSolver® thermostatic balancing valves can also be used to balance the return flow between the master mixing valve and water heater. To learn more about this application go to the Balancing a DHWS Return with CircuitSolver page.
