The Rinnai REP199iP is a propane-fired, non-condensing outdoor tankless water heater rated at up to 199,000 BTU and 7.9 GPM. Its standout feature is Smart-Circ, a built-in recirculation pump that keeps hot water ready at the tap and can be scheduled from the Rinnai app. It is built for outdoor wall mounting, so it needs no venting but must be installed where freezing is not a concern. Against condensing rivals it is simpler and cheaper to service but less efficient, with a Uniform Energy Factor of 0.82. It suits larger homes with high simultaneous hot-water demand and propane supply.

Owners of Rinnai's high-capacity outdoor units generally report strong, steady hot water and reliable operation over years. The Smart-Circ recirculation is the most discussed feature, praised for fast hot water but noted for added propane use when left on. Complaints center on install cost and the outdoor-only placement.
