How Long Do Hot Water Heaters Last?

The typical water heater tank lasts about eight to twelve years, while tankless water heaters can last upwards of 25 years with proper care and maintenance. Electric water heaters typically last longer than gas heaters because they save energy by using less fuel.

If your water heater is getting up there in age, then it might be time to consider a replacement. After a certain point, it is more cost-effective to install a new system than repair the old one repeatedly.

Common Hot Water Heater Problems

Homeowners may not know what to look for when it comes to the condition of their appliances. Below are some of the most common signs you may need to replace your water heater.

Dirty Heating Element

An electric water heater typically uses a metal element to heat water. Over time, sediment buildup and mineral deposits cover the heating elements, making them less efficient at heating. If the heating elements sustain significant damage, you'll have to replace the entire unit.

Faulty Pressure Relief Valve

Your heater's pressure relief valve serves a safety function and keeps water pressure from getting too high. If your relief valve breaks, pressure can build up, and in some cases, high pressure can cause your water heater tanks to explode.

No Hot Water

If your heater can only produce cold water, then it could be a problem with the heating element. No hot water could also indicate faulty electrical wiring or a problem with the water supply that you'll need a professional plumber to fix.

Pilot Light Issues

A gas burner heater uses a pilot light to heat water. If there is a faulty gas connection, the pilot light will not burn correctly. Faulty pilot lights can also produce carbon monoxide, a colorless, odorless gas that can pose a significant health hazard.

Rusty Water

Another sign of when to replace your water heater is rusty-colored water. A corroded tank will leach substances in your water, turning it a hazy brownish-red color. If the tank is too far gone, you'll need a new water heater.
