Life Expectancy

A typical water heater should last nearly 11 years, tankless heaters enjoy a life expectation of 15 to 20 years. Hard water will shorten the lifetime, consistent maintenance definitely will extend that.


Tankless heaters are generally deemed even more energy efficient as compared with traditional heaters due to the fact they don’t need to constantly heat a tank of water. Tankless heaters heat water right away any time a hot water tap is actually opened up. But not all conventional heaters are really designed equally.
