Rinnai RE Series REP160iN Tankless Water Heater with Integrated Pump, Indoor NG

The Rinnai REP160iN is a non-condensing natural gas tankless water heater from the RE Series with an integrated recirculation pump. Rated at 160,000 BTU and 6.6 GPM, it suits small to medium homes and remodels where the unit goes indoors.

Smart-Circ recirculation learns when the household uses hot water and runs the pump to match that schedule. Homes without a dedicated return line can achieve recirculation by adding a thermal bypass valve. The heater carries a 0.81 UEF and is Wi-Fi ready with the Control-R module.

About the size of a small suitcase, the unit fits non-traditional spaces such as attics and crawl spaces. Concentric PVC/CPVC venting places exhaust in the inner pipe and fresh air in the outer one, so a single wall or roof penetration serves as a direct-vent system.
