Watts heat H2O hot water recirculation system provides hot 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. Caution: This system is not designed for tankless water heaters.
- Includes two 12 In. supply line, two reducing fittings from 1/2 In. FTP to 3/8 In. MPT and two mounting screws
- Must be used in conjunction with Watts hot water recirculation systems, models 500800, 500805 and HWRS-WH
- Can also be installed parallel to existing sensor valves to increase the speed water recirculation
- A kit may be needed for each hot water loop, valve should be located at the faucet furthest from the water heater in each loop
