Rinnai Tankless Water Heater (RU-EN)

The RU-EN series of Rinnai tankless water heaters is ideally designed for outdoor use. At about the size of a small suitcase, it can fit in just about any space. Like all tankless water heaters, the unit delivers a continuous flow of hot water and heats the water as you need it, thus providing savings on energy consumption. This series has an efficiency rating of up to 0.93 UEF. Because the Rinnai RU-EN series uses SENSEI™ advanced condensing technology, the unit can run during cold temperatures outside, down to -4°F.

The unit delivers on your investment, with twice the lifespan of an equivalent tank hot water heater. The RU-EN series comes in four different models to suit your water heating needs:

RU130EN (up to 130K BTU, up to 7 gallons/minute)
