How Long Does a Water Heater Last?

You probably don’t think about your water heater at all until it stops working. And you’re facing cold showers. It works hard to provide your Clearwater household with warm water 24/7, and, naturally, it will eventually wear out.


Here’s how long you can expect your water heater to last and some hints that yours is nearing the end of its life. In conclusion, how long your water heater will keep running depends on what model you have and how often it’s on.

Tank Water Heater

The majority of people have a tank water heater that contains 40 to 50 gallons of water. This style continuously heats water, so it’s always at the right temp when you need it. Tank water heaters are popular as a result of their more economical purchase price, but they don’t often last as long as other models.

Here’s how much time you can expect yours to run:

Tank water heaters can fail because of a lot of troubles, but a rusted tank is one of the most typical. Your water heater has a special part called an anode rod that extracts corrosive particles from the water. At some point, the rod will corrode, and particles will build up at the foundation of your water heater, corroding the lining in the tank.

Tankless Water Heater

A tankless water heater has a much bigger life span than its tank-style equivalents. These water heaters can last as many as 20 years.

Along with working longer, tankless hot water heaters are highly energy efficient. Rather than storing huge amounts of water that’s heated continuously, a tankless model warms up water when you want it. This gets rid of standby heating and the effect it has on your monthly energy expenses.

You might not be aware, but heating up water takes up a large chunk of your energy bills. In actuality, it’s the second biggest source of energy utilization in an average home, according to ENERGY STAR®.

Tankless water heaters are higher priced than tank water heaters, but they have long-term energy savings. They are typically 24% to 34% more efficient than a water heater that retains water, according to the U.S. Department of Energy.
