Rinnai's super-high efficiency plus (UEF .98) condensing indoor/outdoor tankless water heater models offer advanced technology that adapts to suit the needs of any household. Our convertible on-demand water heaters are able to operate using either propane or natural gas thanks to a Smart Sense gas control system and can be installed indoors or outdoors with one simple adaptation thanks to the new Versa Vent. Additional features on this natural gas and propane water heater include an easy-to-use interface and Quick Flush function for simplified flushing. With Smart-Circ, Rinnai RXP model water heaters learn your water usage patterns to start circulating hot water on your schedule, anticipating your hot water needs for a shorter wait and saving energy during times when you don't typically use hot water. Unlike tank heaters which accumulate rusty sediments, this tankless water heater has a longer lifespan. Designed to be extremely compact, this small water heater only takes up the space of a small suitcase, letting you reclaim some of your home's most valuable real estate. This Energy Star qualified small hot water heater can be made even smarter with Wi-Fi connectivity through the Control-R module (sold separately).
