Hot water recirculating systemwith dedicated return line

Rinnai’s Recirculation Push Button accessory activates the tankless water heater recirculation pump by simply pressing the button.

If your home does not have a dedicated return line, select Rinnai tankless water heaters can offer faster hot water without adding an additional cold return line. This technology allows for the simple installation of a thermal bypass valve at the fixture farthest away from the water heater. Once installed, the unit temporarily uses the cold water line for recirculation.
