How Long Do Water Heaters Last?

If you are asking yourself, “How long do water heaters last?” you’ve likely wondered the same thing about your current unit. After all, you don’t want to spend your hard-earned money on a unit that won’t last. So how do you determine the lifespan of your water heater? Here are a few tips. Keep in mind that the lifespan of your water heater may vary depending on its model and location in the home.

Traditional tank-style water heaters have a lifespan of between eight and twelve years, but the number may be even shorter. The type of water running through your heater, its location, and how much you use it all influence its lifespan. A gas-powered tank water heater will generally last for eight to 12 years. Gas-powered tankless models, on the other hand, can last 20 years or longer. Their lifespan depends on factors such as the type of water you use and its hardness.

Inspecting your water heater every so often can help you decide if it’s time for a new one. You should also consider whether the warranty covers repairs for the unit. Electric tank-style water heaters typically come with a six-year warranty. If it’s older than that, expect to have to perform maintenance on it. If you’re not sure, call a plumber to have it checked.
