Rinnai RxP199i Condensing Indoor/Outdoor Tankless Water Heater

Say goodbye to running out of hot water with the Rinnai SENSEI RXP199iN Tankless Water Heater. This super high-efficiency condensing unit is a game-changer for modern homes. It's incredibly compact—about the size of a small suitcase—meaning it can fit almost anywhere, indoors or out with the Versa Vent adapter. The best part? It includes Rinnai's Smart-Circ Intelligent Recirculation pump, which actually learns your family's hot water usage patterns and schedules recirculation accordingly. This means you get hot water when you need it most, without wasting energy running all the time.

With a 0.98 Uniform Energy Factor (UEF) and an ENERGY STAR qualification, the RXP199iN is one of the most efficient tankless water heaters on the market, saving you money on utility bills. Thanks to Rinnai's Smart Sense Gas Valve Technology, the single unit can be installed with either Natural Gas or Propane with no conversion kit needed. It is also Wi-Fi capable for easy control and monitoring through the Rinnai Central mobile app and the addition of the RWM200 module. Invest in endless, efficient hot water and smart comfort!
