Traditional domestic hot water recirculation system balancing is time-intensive, laborious, and expensive. For decades, balancing has been the combined effort of several contractors spending a lot of time manually balancing and rebalancing the domestic hot water system (DHWS) to achieve the required flow needed to obtain the same temperature in each branch.
While manual balancing methods are good in theory, they flounder in practice resulting in hefty labor costs and frequent callbacks due to a manual balancing valve’s inability to react to dynamic changes in the system.
To conquer the challenges inherent to conventional manual balancing methods, ThermOmegaTech® invented the CircuitSolver®, the market’s first thermostatic balancing valve for a DHWS.
How It Works:
Installed at the end of each branch before the return, the CircuitSolver® uses our unique Thermoloid® wax thermal actuator to modulate the valve open and closed in response to temperature variations to maintain a specified temperature at the end of each branch. During the initial start-up of a DHWS, the valve is wide open and will begin to close once the system temperature requirements are met.
Once the system is balanced, the valve will remain in its closed* position to keep hot water in the line and only modulate open to establish flow when the water temperature drops below the valve’s set-point. Once the temperature rises back up to the valve’s set-point again, the CircuitSolver® automatically modulates back towards its closed* position. This automatic response to temperature allows the balancing valve to dynamically adjust to the varied usage rates in a DHWS throughout the day. No manual balancing is required, simply install the valves and watch them work!
*Note: The valve will never fully close, always allowing a small bypass of flow to the return to avoid dead-heading the recirculation pump. The limited flow to your return line will reduce system wear, electricity, and water usage and improve overall system operation.
The CircuitSolver® thermostatic balancing valve is comprised of 100% high-quality stainless steel components – a valve body, valve plug, spring, carrier, and thermal actuator.

CircuitSolver® can be used in any building with a domestic hot water recirculation system to maintain a thermally balanced system and have hot water readily available at each fixture. Used in commercial buildings of all sizes and DHWS’ with varying complexity, CircuitSolver® installations often include hospitals, schools, hotels, high-rise buildings, and multi-family apartment buildings.
