CircuitSolver® opens when the water temperature drops below the set-point of the valves. This creates a path of least resistance inducing flow until the temperature reaches the valve’s set-point again, then the CircuitSolver® closes. The valve modulates based on temperature differential from set-point so there is never a sudden closing which could create a water hammer. Since the valve movement is automatic, manual adjustment is not required. This eliminates the typical testing and balancing procedure that is needed to adjust valves that restrict flow based on pressure differential. By allowing only fluid that cools below the valves’ set-point to flow to the return, CircuitSolver® valves minimize heat loss by reducing the average temperature and GPM of the return line. This eliminates the need for oversized recirculation pumps, reducing pipeline erosion and energy waste. If you are adjusting pressure regulating valves for your pressure booster pumps in a multi-story building, be sure the hot water system is full of cold water. Then, all of the CircuitSolvers will be in the full open position.
