The TWH Tankless Water Heater Mixing Panel’s primary application is as a multizone mixing device for tankless DHW heaters. Both the primary and secondary pumps are activated once every 24 hours, for 15 minutes, to ensure that potable water in the piping is not stagnant.
When the panel receives a call for heat, both pumps are activated, and the thermostatic control head in the 3-way mixing valve will automatically regulate the water temperature in the secondary circuit. The TWH070XPZ is designed for applications where there is an extremely high flow resistance in the heat source.
