The Lifespans Of Different Heaters

How long your water heater lasts depends on the model you have.

If you’ve got a standard, tank water heater, you can expect it to last anywhere from 8 to 12 years. If you care for it, you might even extend the life by a few years. Tank water heaters usually give out when the anode rod can’t collect particles of debris anymore.

However, with a tankless system, you should expect a lifespan of up to 20 years.

They last longer because they’re not constantly supplying your home with hot water. Instead, they warm it up when you need it. However, they are still susceptible to corrosion after years of use.

To care for all your heaters, you should perform regular flushes and drains, keep the area where the heater is stored clear at all times, and make sure you check for the warning signs that your heater isn’t safe.

Since water heaters account or about 16% of all house fires, if you notice signs of extra soot around the gas chamber, call a professional at once.

How Can I Find Out How Old My Water Heater Is?

Hey, everyone forgets their age from time to time! Your hot water heater is no exception. If you can’t recall when you bought your water heater, or if it was already in the house when you moved in, don’t panic.

There are ways to tell its age, like the rings on a tree. Start by looking at your heater’s serial number. To find it, look on the top part of your heater.

The letters (A,B,C) stand for the month in which it was made. (A is January, B is February, etc.)

The two numbers next to those letters, like a “12” for example, will tell you the year it was made. Our made-up heater was created in 2012.

If you’re not sure, or if your serial number looks different, always check on the website of the company that made your heater.

What Are The Warning Signs Of Age?

Look at for the following:

  • Consistent drops in the water’s temperature
  • Spills around the base of your water heater
  • Hot water that’s consistently tinted a yellowish or reddish shade
  • Loud, banging and clanging noises coming from your water heater. This is a sign that calcium has built up in your tank.
