WHP 130 MBH Water Heater Pump Panel with DHW Priority

The WHP Water Heater Pump Panel’s primary application is as a flow activated DHW priority switched pump. Intended to be used with DHW tanks as a heat source, the pump is activated once every 24 hours, for 15 minutes, to ensure that potable water in the piping is not stagnant. The flow activated DHW priority switch turns off the primary pump when there is flow in the regular DHW line.
