Rinnai REP199eN Outdoor Natural Gas Tankless Water Heater with Pump, 199,000 BTU

The Rinnai REP199eN is an outdoor, non-condensing tankless water heater for natural gas that includes a recirculation pump. Delivering 199,000 BTU and up to 7.9 GPM, it suits small to medium homes and remodels with an exterior mounting location.

Smart-Circ recirculation tracks daily usage and readies hot water to match the household routine. Where no dedicated return line exists, an optional thermal bypass valve still makes recirculation possible. The heater fires only when a tap opens, so there is no stored water to keep hot, and the outdoor design needs no venting.

Efficiency is rated at 0.81 UEF, the set temperature runs from 120 to 140°F, and multiple fixtures can draw hot water simultaneously. Adding the control-r module makes the unit Wi-Fi ready, and its small cabinet fits exterior walls with tight space.
