How Long Do Electric Water Heaters Last?

Like other appliances in your home, an electric water heater has a limited lifespan. Knowing the signs of a faulty water heater before it completely stops working; otherwise, you may face cold showers and potential water damage. Replacing your water heater before such issues happen will save you time, stress, and money.

A water heater’s life span depends on various factors, including the quality of the unit, how often it receives regular maintenance, and the level of water usage. If your water heater is heating water sufficiently without leaks or strange noises, it can last over 10-15 years. If you’re unsure how old your tank unit is, check its serial number with the manufacturer.

How Long Does A Tankless Water Heater Last?

Tankless water heaters are very popular, as they are energy-efficient and heat the water as needed. Since there’s minor wear and tear, the tankless water heaters can last approximately 20 years and longer if maintained properly. You can contact a professional for water heater repair in Modesto for an inspection, any needed repairs, or replacement options.

When To Replace Your Water Heater

Inspect the following signs:


If your water heater is older than ten years, you may want to get an inspection and take note of any problems that arise. Water heaters can last up to 20 years, but you will want to resolve an immediate issue. Accidents can be costly, dangerous, and cause water damage to your home.

Strange Rumbling Noise:

If your water heater produces banging or rumbling sounds, there might be sediment accumulation at the bottom of the tank. Excessive sediment build-up inside the water tank is a telltale sign of a new water heater.

Cold Water or Lukewarm:

When your water heater starts providing cold or lukewarm water, it might be due for replacement. Consult the professionals to inspect it to determine whether you need water heater replacement.

Discolored Water:

Brown, red, and yellow colored water is a sign of a corroded anode rod in the tank. A rusted water heater is far away from repairing. You will have to replace it if you’re in a similar situation.

Water Leaking:

A leaking water heater is indicative that you need to replace it as quickly as possible. If the leak isn’t from a fitting or valve, your water heater tank may be cracked or rusted.

How To Prolong The Lifespan of A Water Heater?

Consider the following methods to extend your water heater’s life longer:

Regular Maintenance:

Periodic inspections and maintenance can help your water heater work efficiently and last longer. An experienced plumber may also inform you about the warning signs that your water heater is about to fail.

Use Scale Inhibitor:

If you live in an area, having a supply of hard water and limescale mineral deposits can damage both conventional and tankless water heaters. These sediments accumulate in the tank, causing hot water to get suddenly too hot. To protect your water heater from shortening lifespan, use a scale inhibiting filter to help extend its life.

Drain Cleaning:

Drain your water heater tank every 6 to 12 months to clear sediment. You may call a professional for drain cleaning services if you’re unsure how to perform this task yourself.

Anode Replacement:

The water heater’s anode rod absorbs ions and minerals, rusting the tank inside. Consider inspecting annually and replacing the anode rod after 2-3 years when it deteriorates. For additional protection, install a second anode rod. Doing so will help extend the lifespan of the water heater.
