What is the life expectancy of a Rinnai Tankless Water Heater?

The estimated life expectancy of a Rinnai tankless hot water heater is up to 20 years (that’s about double of a traditional hot water heater tank!). Actual performance will vary depending on water quality, usage rates, environmental conditions and regular maintenance. This longevity is one of the factors that makes a Rinnai tankless water heater a money-saving choice over time.
