The Average Life Expectancy for a Tankless Water Heater


At Bradbury Brothers, we believe the benefits of tankless water heaters are proven and if you have to – or want to – install a new water heating system, tankless (also called “on-demand”) is the way to go. If you are remodeling or building new this year, you’re making a major investment in your property, and an article in The New York Times says “homeowners are staying put.” So you may be living in your current house a long time.

What is the Life Expectancy of a Tankless Water Heater?

Like a lot of things, the answer is, “It depends.”

Manufacturers can only predict a unit’s life expectancy based on normal usage and average upkeep. Tankless water heater maintenance requirements are not owner-intense, but they are very important.

Tankless water heaters are less exposed to water-based corrosion than regular water heaters, which are exposed to moisture 24/7. A traditional water heater lasts about 12 years; a tankless water heater lasts about 20 years.

The U.S. Department of Energy estimates gas-fired tankless heaters save an average of $108 in energy costs per year over their traditional tank counterparts, while electric tankless heaters save $44 per year.

When you do the math, tankless water heaters are a better investment for your budget and your planet. Conditions that affect the longevity of your tankless water heater include:

  • Water Quality – Hard water is exactly that: tough on appliances and plumbing systems throughout your home or office. It can reduce a water heater’s lifespan by 2 or more years!
  • Location – Water heaters located in garages or crawl spaces have to work harder to heat the water.
