How long do water heaters last?

by: Posted: Updated: Getting the most out of your water heater are traditionally outfitted with storage tank heaters. More energy-efficient and hybrid/heat pump water heaters are relatively new to the scene. Whether you’re looking to replace your water heater or upgrade to a new one, the lifespan of the unit matters.

How long your water heater lasts will depend on the type, build quality, the water quality in your area and how the heater is maintained. Water heater lifespan by type Traditional tank water heaters have the shortest lifespan, lasting an average of eight to 12 years. Exposure to water, oxygen and minerals over time corrode the tank from the inside, causing it to leak.

This process is usually what causes a traditional water heater to expire. have the longest lifespan and are capable of lasting around 15 to 20 years. There is no tank to degrade over time, and they don’t operate constantly the way a traditional tank heater does.

Eventually, though, tankless water heater components may also experience corrosion. Hybrid water heaters typically last for 13 to 15 years. Like tankless water heaters, they don’t run continuously, which increases their lifespan compared to traditional tank units.

Still, they do contain a tank, so they won’t last as long as tankless models. Other factors that influence a water heater’s life expectancy Quality is an obvious factor in a water heater’s longevity. Higher-quality units tend to have thicker tanks, better insulation and superior components overall.

Heaters that have been routinely maintained and cared for last longer than neglected units. Water quality is another significant factor — hard water can reduce the water heater’s lifespan by causing mineral buildup on the heating element and in the tank. Signs it may be time to replace your water heater If you’ve noticed that your energy bill has gotten higher, it could be a sign that your water heater is no longer performing optimally.

Knocking noises in the tank, rusty, cloudy or discolored water and leaks are all telltale signs that your water heater should be replaced. How to extend water heater life expectancy Flush your water heater yearly Flushing your water heater helps clear out sediment that builds up in the tank. Manufacturers generally recommend flushing a water heater once a year, but if you live in an area with hard water, it’s safer to go with twice a year.

Replace the anode rod regularly The anode rod in a tank or hybrid water heater attracts particles of limestone, iron and other minerals away from vulnerable components in the tank. Most water heater manufacturers recommend replacing the anode rod every one to three years. Monitor the pressure valve Tank and hybrid water heaters have a pressure valve that releases pressure if the tank overheats.

If the valve is not working properly, it can cause the tank to rupture — and in rare cases, explode. Install a water softener If your home experiences hard water, consider installing a . Add an expansion tank In a closed plumbing system, a tank water heater can put stress on pipes and plumbing fixtures through the process of thermal expansion, which happens when water is heated.

An expansion tank is essentially an overflow tank that prevents excessive pressure, protecting your plumbing and the heater itself. Test your water pressure Normal water pressure in a home should be under 80 psi. When water pressure is too high, it puts stress on the water tank.

You can test this with a . Adjust the temperature Most manufacturers recommend keeping your water heater at about 120 degrees for optimal performance. Best tank water heaters This 50-gallon electric water heater can effectively support households with three to five people.
