How Long Does a Water Heater Last?

You probably don’t think about your water heater at all until it stops heating. And you’re dealing with chilly showers. It works hard to provide your Dayton household with hot water 24 hours a day, and, naturally, it will give out at some point.


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

Tank Water Heater

Most homes have a tank water heater that contains 40 to 50 gallons of water. This style constantly makes water warm, so it’s always at the right setting when you need it. Tank water heaters are popular as a result of their lower cost, but they don’t usually last as long as other kinds.

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

Tank water heaters can stop working due to many problems, but an oxidized tank is one of the most frequent. Your water heater has a special component known as an anode rod that extracts corrosive fragments from the water. At some point, the rod will oxidize, and particles will increase at the base of your water heater, corroding the lining inside the tank.

Tankless Water Heater

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

Along with running longer, tankless hot water heaters are extremely energy efficient. Instead of storing big amounts of water that’s warmed constantly, a tankless model heats water when you need it. This does away with standby heating and the effect it has on your monthly energy bills.

You might not be aware, but warming up water is a big portion of your utility expenses. In fact, it’s the second largest source of energy consumption in a regular house, according to ENERGY STAR®.

Tankless water heaters are more expensive than tank water heaters, but they have lifelong energy savings. They are typically 24% to 34% more efficient than a water heater that stores water, according to the U.S. Department of Energy.

4 Indications Your Water Heater is Dying

Your hot water heater will start to show signs that it’s wearing out. Here’s what to watch and when to contact a plumbing professional like Stevenson Service Experts.

1. Inadequate Enough Hot Water

This is one of the most typical symptoms that your water heater is nearing the end of its life. You might see heated water getting used up more rapidly, or that it’s taking extra time for water to warm up.

2. Leaks

It’s time to call a plumber if you’re experiencing water leaks or water accumulating by the bottom of your water heater. In some cases you could just need to have connections secured or a piece replaced, but it could also be a sign the tank is compromised.

3. Water Isn’t Clear

If you are in a region with hard water and don’t have a water softener, you’re probably used to having cloudy water. But if your water all of a sudden changes from clear to cloudy or starts smelling metallic, we recommend having your water heater checked by a professional to prevent damaging leaks. Quick changes in your water clarity means sediment is possibly building up in the tank and rusting it.

4. Strange Noises

It’s expected for your water heater to produce some noise as it operates. But popping and rumbling isn’t normal and is a symptom you should call for specialized assistance. As sediment grows in the tank, your water heater has to work harder and may need added energy in the process.
