How Long Do Water Heaters Last?

Some Important Numbers

water heaters Plymouth County, MA Water heaters like the one in your Plymouth County, MA home are often unsung heroes, diligently providing you and your family with warm showers and cozy baths. So, next time you step into a soothing shower, give a nod of appreciation to your water heater—it’s been working hard behind the scenes!

Like all appliances, water heaters have a finite lifespan. So, how long can you expect your trusty water heater to soldier on? How long do water heaters last? The answer depends on the type of water heater you have and how well you maintain it. Let’s take a closer look at the different types of water heaters and their life expectancies.

Traditional Tank-Type Water Heaters

These are the workhorses we’re most familiar with—the ones that store hot water in a tank. On average, they last 8 to 12 years. Inside the tank, an anode rod valiantly shields the interior lining from corrosion. As it attracts corrosive particles through a process called electrolysis, the rod gradually corrodes. When it can no longer perform its duty, those particles settle at the tank’s bottom, potentially damaging the lining. Once corrosion sets in, the water heater enters its twilight years.

Tankless Water Heaters

Also known as “on-demand” water heaters, these sleek devices don’t maintain a constant supply of hot water. Instead, they heat water as needed. Their secret weapon? No anode rods! As a result, tankless water heaters can last up to 20 years. They’re like the marathon runners of the water heater world, going the extra mile without breaking a sweat.

Signs of Aging

Wondering if your water heater is nearing the end of its lifespan? Look out for these telltale warning signs:

  1. Poor Performance: If your once-hot showers are now lukewarm, your water heater might be waving a white flag.
  2. Leaks: Puddles around the base? Uh-oh. Leaks spell trouble.
  3. Cold Water Surprises: When your morning shower turns icy, it’s time to investigate.
  4. Abnormal Noises: Clanks, groans, or hisses mean your water heater might be composing its swan song.

How Old Is Your Water Heater?

Your water heater’s serial number holds the key to its age. Even if you’ve misplaced the manual, fear not! The serial number, usually a letter followed by numbers, resides on the upper part of the heater. Decode it, and you’ll know when your trusty appliance rolled off the assembly line.
