How Long Do Water Heaters Last?

Types of water heaters, and their lifespans:

The type of water heater is one of the most significant determinants of its lifespan. Here’s a breakdown of the common types and their expected durations. Let’s start with the conventional water heaters.

Traditional tank-style water heaters are the most common type of water heater. They work by heating and storing that heated water in a tank until needed. Typically, they last between 8 to 12 years. The lifespan is influenced by the tank material, with glass-lined tanks being more common and less durable compared to stainless steel tanks.

Then there are tankless water heaters. Also known as on-demand water heaters, these heat water only when needed. Tankless water heaters generally have a longer lifespan, ranging from 15 to 20 years. Their longevity is partly due to the absence of a tank, which is prone to rust and sediment buildup.

Finally, we’ll mention heat pump water heaters. These units are uncommon. They use electricity to transfer heat from the air or ground to heat water, making them more energy-efficient. They typically last about 10 to 15 years, depending on the model and usage conditions.

Workmanship and installation matter

The quality of installation and workmanship is a key aspect in determining the lifespan of a water heater. Poor installation can lead to a ton of issues, including leaks, inefficient heating, and even premature failure. It's essential to hire a qualified plumber for installation to ensure that the water heater is set up correctly, adheres to local codes, and operates efficiently.

Maintaining your water heater

Routine plumbing service is non-negotiable if you want to maximize the life expectancy of your water heater. Mr. Rooter’s water heater maintenance services are comprehensive, but here are just some things to remember:

• Flushing the tank annually helps remove sediment buildup, which can cause the tank to corrode and reduce efficiency.
• Checking and replacing the anode rod every few years can significantly extend the life of a conventional water heater. The anode rod attracts corrosive elements in the water, preventing them from rusting the tank.
• Installing a water softener can mitigate this issue. Hard water, which contains high levels of minerals, for example, can cause scale buildup and reduce the efficiency and lifespan of water heaters.
