Life Expectancy of a Hot Water Heater

Dec 19, 2022

While most plumbing professionals will tell you that the average life expectancy of a hot water heater is ten years, there are actually several other factors to consider. These include what type it is, how it was installed, the water quality, and how well it is maintained.

Some traditional water heaters continue to operate efficiently for more than 10 years while tankless water heaters (which do not maintain a steady supply of hot water) are known to last for 20 or more years.

No matter what type of water heater you have, it’s important to know the signs of aging ahead of investing in costly repairs or replacements.

Signs of an Old Hot Water Heater

No hot water: If the water is not heating up properly, the heater’s service life may be nearing the end. Even if the water supply is high, the failure to heat may be a sign that you need a new hot water heater.

Discolored water: An aged water heater will have rust that may lead to red or orange water. This kind of dusty galvanized piping is a sure sign that the water heater is in its final stage of operation.

Water leaks: Infrequent water leaks can be fixed by simply tightening or replacing the valve. But ongoing water leaks is a sign that a crack in the tank may be responsible. This type of water heater failure may require a replacement.

Rumbling sounds: At the end of a water heater’s lifespan, you may hear strange noises. These are caused by long-standing sediment buildup that hardens and causes the heater to squeak and bang back and forth.

Old expiration date: Look for the manufacturer’s sticker and identify the serial numbers. Typically, the first two numerals indicate the projected year of expiration. Keeping tabs on that year as the water heater ages can help determine its life expectancy.
