How Long Do Water Heaters Last

Have you ever gotten an unexpected (and rather unwelcoming) blast of cold water when showering or washing your hands? If you have, it’s a sign that your water heater might be hitting retirement age. So, how long do water heaters last, and when should you replace yours? The plumbing experts at Roto-Rooter are here to give you the answer.

Traditional Tank-Type Water Heaters

A traditional tank-type water heater lasts on average from eight to 12 years. Inside these tanks there is an anode rod that protects them from corrosive particles. After eight years, that rod begins to corrode or deteriorate. With the anode rod out of the picture, the rest of the tank is left unprotected and corrodes. And once that happens, it’s time to get a replacement.

Tankless Water Heaters

Tankless water heaters can last up to 20 years or even longer, depending on the conditions. The difference is that tankless water heaters aren’t constantly working, which results in them having a longer life. While corrosion will eventually happen, tankless water heaters are great at conserving energy and requiring less maintenance.

How to Find How Long Your Specific Water Heater Will Last

So far, we’ve given an average lifespan for all water heaters. But there’s a way to get a more personalized answer. If you can find your water heater’s serial number, you can call the manufacturer to find out when your heater was made and how long that specific brand lasts. While you’re on the phone with them, it never hurts to get your warranty information, too – you might need it later!

Signs to Watch Out for with Your Water Heater

Once your water heater goes past its half-life, it’s a good idea to keep a lookout for the following signs:
• A banging or loud noise coming from your water heater.
• Your hot water is tinted with a red, yellow, or brown color.
• A sudden drop in water temperature.
• Water that’s pooling around the base of your water heater.
If you notice any of these signs in your home or business, you should call a professional to come take a look. The expert plumbers at Roto-Rooter have years of local experience and are trained to diagnose any problem your water heater might be having.
