HWRS
heat H2O Hot Water Recirculation System
Watts heat H2O Hot Water Recirculation System, model HWRS-WH, provides water to a faucet or shower instantly, eliminating water waste caused by waiting for water to heat up. This pump offers quiet, maintenance-free operation and includes a programmable timer that can be set to activate the pump only when needed or set it to run 24-hours a day. The device uses the pump at the water heater and a patented under-sink sensor valve to create a pressure differential. The pressure differential allows the cold and cool water in the hot water supply line to bypass into the cold water supply line at a low volume through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a NO WAIT temperature throughout the home.
The Sensor Valve Kit (sku #0955801) works only with Hot Water Recirculation System models 500800, 500803 and HWRS-WH. Kit comes complete with one sensor valve, two 12-inch supply lines with fittings. The valve kit is designed for a branched hot water line to ensure hot water gets to all areas of the home. Not to be used with a dedicated return line to the water heater.
Caution: The system and sensor valve kit are not designed for tankless water heaters.
