What Is The Average Life Of A Water Heater
According to the National Appliance Energy Conservation Act , the average lifespan of a water heater is about 8 to 12 years. However, this does not mean that your water heater will last exactly 8 or 12 years. Several factors can affect the lifespan of your water heater, such as how often you use it, the quality of the unit, the hardness of your water, and whether or not you properly maintain it. With proper maintenance and care, your water heater can last much longer than the average lifespan.

Why Heater Age Matters

When water heaters go bad, they can go really bad. Running out of hot water in the middle of a shower is the least of it.
A worn-out water heater can also leak, put out water thats too hot or too cold, reduce your water flow to a trickle or cause water to smell or look bad.
In the worst case, a heater can literally explode. Water damage from a ruptured heater can easily cost thousands to repair.
Warning signs like little or no hot water, low flow, and leaking fittings can alert you to the fact that your water heater is reaching the end of its useful life. This can help you decide whether to try to repair or replace the heater.
A timely replacement of a water heater thats about to fail can save lots of time, money, and energy compared to waiting for it to go.
And one of the best ways to determine whether your heater is soon to become a problem is to know how old it is. But how do you do that?
As it turns out, the answer gets a little complicated. But if you use the following information, you can reliably tell how old your water heater is and, hopefully, replace it before trouble starts.

How Old Is My Water Heater

Water heaters can last a long time. But the expected lifetime for a water heater varies considerably. Some models can give faithful service for up to 20 years. However, others may only last around eight years.
It partly depends on whether the heater uses electricity or gas for the fuel source. The specific unit also has an effect. Some manufacturers and models tend to last longer, sometimes a lot longer.
The amount of hot water you use also has a major impact on heater life. Finally, the mineral content of the water also affects it. Higher mineral content means a shorter-lived heater.
With all this in mind, if you have a standard electric water heater, you can normally expect it to be in good shape for 10 to 15 years. Of course, thats plenty long enough to lose the original sales receipt for the heater as well as the warranty and other info.
Unless you keep good records, you likely cant recall exactly when you acquired your water heater. If the heater was already installed in a property when you moved in, its even less likely that youll know when the heater was manufactured, purchased, and installed.
