RE180eN is the perfect combination of high efficiency, comfort and value in a natural gas non- condensing tankless water heater from Rinnai. Ideal for small to medium homes or remodels. Only the size of a small suitcase, is easy-to-install, reliable, and perfect for outdoor locations; Rinnai products provide peace of mind with warranties that surpass the competition.

In a non-condensing tankless water heater, such as the RE180, once you turn on the tap, cold water goes into the tankless heater and the flame is activated. Water is heated as it passes through the coils in the copper heat exchanger, exits the water heater, into your pipes, and up to the fixture calling for the hot water. Depending on the amount of hot water called for, the flame adjusts accordingly to heat more or less water.

Up to twice the lifespan of most tanks

Never run out of hot water

Compact size to fit every space

Benefits of a Tankless Hot Water Heater:

• Endless hot water - Heats water as it goes through the pipes, offering endless hot water for your home (or business)
• Hot water on demand - Once you turn the water on, hot water runs through your pipes and out the faucet! Virtually no time or water is wasted waiting for the water to heat up
• Highly Efficient - Gallon for gallon, you will spend less money heating your hot water. With a tankless system, the water is heated on demand rather than sitting in a storage tank. A storage tank typically heats the water intermittently throughout the day and night not only when it is needed. This unit is Energy Star Qualified and features an Energy Factor of 0.96 (the closer to 1.0 the better)
• Long-lasting - Unlike a storage tank in which the water sits in the tank all the time creating sediment and rust, a tankless water heater will last longer
• EZ Connect - Allows for connection of two units together
