Do Tankless Water Heaters Last Longer?

Do Tankless Water Heaters Last Longer?

You invest money into the systems that keep you comfortable, like your water heater. And that’s why you always hope that the investment will carry you through for many years to come without many problems. When you’re spending money on a tankless water heater, you’re investing in a system that uses a lot less energy to operate, but will it last longer than a conventional tank unit?

Tankless Water Heaters Have a 20-Year Lifespan

The average life of a tankless water heater is about 20 years. And the lifespan of a conventional tank unit is about 5-10 years less than this. Although a tankless water heater costs more to operate than the traditional tank water heater, the total energy savings over the years offsets this cost, especially since tankless units tend to last longer.

Of course, like any system, the lifespan will depend largely on the way you treat the system. If you schedule maintenance visits and perhaps even consider a water softener to prevent scaling, chances are high that the unit will fulfill its expected lifespan.

In addition, you might consider more than one tankless unit for a larger household. Tankless water heaters struggle when several people use the hot water at once. A separate unit for each bathroom means a steadier and more reliable hot water supply, and you’ll balance usage between the two units, leading to longer lifespans for each.

All Water Heaters Need Maintenance

No water heater will last forever, but you may be able to extend its lifespan by scheduling regular water heater maintenance. Calling a professional to your home once or twice a year to look at your water heater may allow it to last a few years longer than you’d expect.

Maintenance visits allow a technician to discover whether or not your system is affected by scaling, a problem that comes up in areas with very hard water. Descaling the inside of the tankless water heater can add years onto its life, preventing it from clogging up or overheating.
