The CircuitSolver® Union Assembly’s primary component is the CircuitSolver® which is a self-acting thermostatic recirculation valve that automatically and continuously maintains a set temperature at the end of each branch or riser in a domestic hot water system. Since the CircuitSolver® responds to water temperature and controls flow to the return, it eliminates the need to manually balance the system.
