Circuit Solver THERMOSTATIC RECIRCULATION VALVE FOR DOMESTIC HOT WATER SYSTEMS TM The Problem The Solution Install a Circuit Solver™ on each hot water supply branch line immediately downstream of the last runout to a hot tap. 1 Water fmows to the path of least resistance. 2 Many buildings require multiple branches off the hot water supply line. 3 Hot water use is hyper-dynamic, so the path of least resistence constantly changes. 4 Manual fmow control valves cannot effjciently resolve these issues. When entering water temperature is below the Circuit Solver™ setpoint, the thermal actuator will begin to open the valve to establish a fmow rate that will achieve the set point. If the water temperature exceeds the set point by 3°F , the valve will begin to throttle back to fjnd the current equilibrium point. Continuously operating at the optimum temperature minimizes system heat-loss thereby saving energy. 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 fjxture.
