How Long Does a Water Heater Last?

You probably don’t think about your water heater at all until it quits heating. And you’re faced with cold showers. It works hard to offer your Savannah family with warm water around the clock, and, naturally, it will give out at some point.


Here’s how long your water heater will probably last and some warning signs that yours is nearing the end of its life. Ultimately, how long your water heater will keep working depends on what model you use and how frequently it’s working.

Tank Water Heater

Most households have a tank water heater that holds 40 to 50 gallons of water. This style constantly warms water, so it’s always at the right temperature when you need it. Tank water heaters are bestsellers as a result of their cheaper price tag, but they don’t usually run as long as other types.

Here’s how long you can expect yours to run:

Tank water heaters can quit working as the result of many issues, but an oxidized tank is one of the most common. Your water heater has a special piece known as an anode rod that clears corrosive particles from the water. Eventually, the rod will corrode, and grit will accumulate at the bottom of your water heater, eating through the lining in the tank.

Tankless Water Heater

A tankless water heater has a much greater life expectancy than its tank-style cousins. These water heaters could last as many as 20 years.

Along with running longer, tankless hot water heaters are highly energy efficient. As opposed to retaining large amounts of water that’s heated all the time, a tankless model warms water on demand. This does away with standby heating and the effect it has on your monthly energy expenses.

You might not be aware, but warming up water takes up a sizeable chunk of your utility bills. In reality, it’s the second largest source of energy use in a standard residence, according to ENERGY STAR®.

Tankless water heaters are pricier 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 clues that it’s wearing out. Here’s what to watch and when to contact a plumbing professional like Coastal Service Experts.

1. Inadequate Enough Hot Water

This is one of the most common signs that your water heater needs to be replaced. You might have hot water running out faster, or that it requires more time to get warm water.

2. Leaks

You should call a plumber if you’re having water leaks or water accumulating by the base of your water heater. In some cases you may just need to have connections tightened or a part replaced, but it could also be a indication the tank is broken.

3. Water Looks White

If you live in an area with hard water and don’t have a water softener, you’re likely familiar with having cloudy water. But if your water unexpectedly changes from clear to cloudy or starts smelling metal-like, you should have your water heater examined by a professional to prevent damaging leaks. Quick changes in your water clarity means sediment is possibly accumulating in the tank and rusting it.

4. Odd Noises

It’s expected for your water heater to make some noise as it runs. But popping and rumbling is never normal and is a hint you need professional support. As sediment builds up in the tank, your water heater has to work harder and could use additional energy in the process.
