How Long Does a Water Heater Last?

You probably don’t think about your water heater at all until it gives up working. And you’re faced with chilly showers. It works hard to offer your Charlotte household with warm water 24/7, and, as expected, it will eventually wear out.


Here’s how long your water heater will likely last and some indications that yours is nearing the end of its life. In conclusion, how long your water heater will last depends on what type you use and how much it’s on.

Tank Water Heater

Many households have a tank water heater that holds 40 to 50 gallons of water. This style constantly heats water, so it’s always at the correct setting when you need it. Tank water heaters are very common as a result of their lower price tag, but they don’t typically work as long as other models.

Here’s how many years you can expect yours to run:

Tank water heaters can fail because of a lot of problems, but a rusted tank is one of the most typical. Your water heater has a special piece referred to as an anode rod that removes corrosive particles from the water. At some point, the rod will corrode, and particles will increase at the foundation of your water heater, rusting out the lining inside the tank.

Tankless Water Heater

A tankless water heater has a much greater working life than its tank-style counterparts. These water heaters may work as many as 20 years.

Along with running longer, tankless hot water heaters are very energy efficient. As opposed to retaining huge amounts of water that’s heated all the time, a tankless model heats water when you need it. This does away with standby heating and the effect it has on your monthly utility expenses.

You might not know this, but warming up water accounts for a large portion of your utility costs. In fact, it’s the second highest source of energy utilization in a standard house, according to ENERGY STAR®.

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

4 Signs Your Water Heater is Going Bad

Your hot water heater will begin showing signs that it’s dying. Here’s what to look for and when to contact a plumbing specialist like Komfort Air Service Experts.

1. Insufficient Enough Hot Water

This is one of the most common clues that your water heater needs to be replaced. You may notice hot water getting depleted more rapidly, or that it requires more time for water to warm up.

2. Leaks

It’s time to call a plumber if you’re noticing water leaks or water pooling near the base of your water heater. In some cases you may just need to have connections tightened or a component replaced, but it might also be a indication the tank is damaged.

3. Water Isn’t Clear

If you live in an area with hard water and don’t have a water softener, you’re typically accustomed to having cloudy water. But if your water all of a sudden goes from clear to cloudy or starts smelling metallic, we advise having your water heater examined by a specialist to prevent damaging leaks. Quick changes in your water clarity means sediment is likely growing in the tank and corroding it.

4. Odd Noises

It’s typical for your water heater to create some noise as it works. But popping and rumbling is never normal and is a symptom you need specialized assistance. As sediment accumulates in the tank, your water heater has to work harder and may need additional energy in the process.
