Ensure You'll Never Wait for Hot Water

Recirculation accessories enable your home to have hot water, faster, when you need it. Solutions include tankless water heaters with built-in pumps or units that can have a pump added. Homes with no dedicated return line can have a thermal bypass valve added to the cold water line for recirculation.

Recirculation solutions available in Rinnai HE+ and SE+ Series tankless water heaters.

Affordable solutions available that do not require addition of a dedicated return line

Recirculation can be controlled via app, smart home devices, push button, scheduled timers, or motion sensors.

Recirculation Benefits

Waiting for hot water can be frustrating, costly, and wasteful. Recirculating technology eliminates the wait, so hot water is always at the ready. Our technology permits this even if your home does not have a dedicated return line.

Recirculation with ThermaCirc360

If your home does not have a dedicated return line, Rinnai's SE+ Series featuring ThermaCirc360 technology can offer faster hot water without adding an additional line. This technology allows for the simple installation of a thermal bypass valve at the fixture farthest away from the water heater. Once installed properly, the unit temporarily uses the cold water line for recirculation.
