Frequently Asked Questions About Rinnai Tankless Water Heaters

How long do Rinnai tankless water heaters last?

The life expectancy (or useful lifespan) of a Rinnai tankless water heater is up to 20 years. Actual life is impacted by water quality, usage and proper maintenance. For comparison, a tankless water heater lasts about twice as long as a tank water heater, making them a better value in the long run.

What is the downside of a tankless water heater?

Rinnai tankless water heaters produce an endless supply of hot water, take up less space, have a lower risk of leaking, are safer, and have a significantly longer lifespan on average. The main disadvantage of tankless water heaters is their upfront cost (unit and installation) is significantly higher than tank-style heaters.

How Much Money Can I Save With An On Demand Water Heater?

Depending on what size storage tank you have now, which model of tankless water heater you purchase, and whether it runs on gas or electricity, you could save from 5% to 69% off your hot water heating bill. How? Most homes use hot water for a total of around one hour per day, but they normally keep at least 40 or 50 gallons of water hot 24 hours a day – every day. Owning a system that removes the storage and heats water only as you use it can significantly reduce your energy consumption.
