How it Works

The thermal actuator inside Circuit Solver modulates the valve between open and closed in response to changing water temperature caused by heat loss, water demand, or any other reason. This constant, automatic response to water temperature enables each hot water branch to quickly and consistently deliver the right temperature of hot water to each connected fixture. The valve is constructed entirely of stainless steel, and is certified to NSF/ANSI 61 and Section 116875 of the California Health & Safety Code.

Recirculation Pump Size Selection

For recirculation pump sizing, Circuit Solver allows the pump(s) to be sized exactly without any need to oversize to account for typical manual balancing problems. ThermOmegaTech recommends using established industry standard pump sizing procedures. For example, the ASPE Design Handbook and ASHRAE Handbook both have established methods for recirculation pump sizing. To aid in calculating the pressure loss across the Circuit Solver valve, refer to the following guidelines, Circuit Solver Design Guide.
