Rinnai RE Series REP199eP Outdoor Tankless Water Heater with Pump, Propane

The Rinnai REP199eP is an outdoor, non-condensing tankless water heater for liquid propane with an integrated recirculation pump. With 199,000 BTU and up to 7.9 GPM, it serves small to medium homes and remodels where the heater mounts outside.

The built-in pump uses Smart-Circ, which learns when hot water is typically used and recirculates ahead of those times. An optional thermal bypass valve allows recirculation where there is no dedicated return line. Because it fires only on demand, it avoids the standby losses of a tank, and outdoor mounting means no venting is required.

Rated at 0.81 UEF, the unit offers a set temperature range of 120 to 140°F and can supply several fixtures at the same time. It is Wi-Fi ready once the control-r module is added, and its compact body suits exterior walls with limited space.
