How Long Do Water Heaters Last?

water heater in closetWater heaters are among the most useful appliances in the home. They’re useful for carrying out tasks like doing the dishes and getting a bath. However, like any other home appliance, they do not last forever. You should keep up with the age of your water heater to avoid the unpleasant event of receiving cold water when you expect some hot water.

How Long Do Water Heaters Last?

If you’ve ever asked, “how long do water heaters last?”, then you should know that different water heaters have different lifespans. The traditional tank water heater lasts between eight to twelve years and the tankless water heater lasts for over twenty years. The difference between the lifespans results from the presence or absence of anode rods.

Factors that affect the Water Heater’s Lifespan

  • The Anode Rod

In the traditional water heater, the anode rod plays a crucial role and, therefore, corrodes easily. If you notice corrosion on the anode rod on top of the water heater, let a plumber replace this for you.

  • Limescale

Both the tankless and the tank water heaters can be affected by limescale, even if it is just a simple amount. It may lead to heating problems, and the best way to resolve this is to flush the water heater with vinegar (undiluted white vinegar).

  • Pressure-Relief Valve

The traditional water heater has a pressure-relief valve that prevents it from exploding from excessive build-up of pressure. You should regularly check to ensure the pressure-relief is in good shape and properly working.

  • Sediments Clogged

In the traditional water heater, there will be sediments clogged at the bottom of the tank. This may affect the effectiveness of the water heater if not flushed at least twice every year.

When is it Time to Replace the Water Heater?

Now that you know what factors affect the lifespan of your water heater, it is time to learn the signs that tell you when to replace your water heater:

  • Gurgling Sounds

This happens when the sediments clog the water heater. You will often hear a gurgling sound and if this clogging becomes too much, the appliance can get heated and even explode.

  • Dampness Around Heater

If there is dampness around the heater, it may be a sign that there is a leak. Here, you may need a plumbing service like Captain Plumber to help replace your water heater.

  • Water Puddles

Water puddles around the water heater are a strong indication that something is very wrong. You will have to hire a plumbing service for a replacement.

  • Absence of Hot Water

When you get cold water instead of hot water, ensure that you get help from a plumber; chances are, the water heater’s lifespan has ended.

  • Tinting in Water

If there’s tinting in the hot water, it could result from rust. This is a sign that it is time for a replacement.
