A typical tank water heater can be expected to last eight to twelve years
before requiring replacement. However, there are many factors that can
play a role in the need for replacement, including a lack of maintenance
and inefficient use of your water heater. Knowing the small steps you
can take that will make a big difference in the life expectancy of your
water heater can help you get the most from this appliance and prevent
premature repairs or replacement.
Turn Down the Temperature
Many water heaters come straight from the factory with their output temperature
set much higher than necessary, up to 140-150 degrees Fahrenheit. The
average household only requires water heated to a temperature of 120 degrees;
this temperature setting will not only prevent accidental scalding, it
will prolong the lifetime of your water heater as well. By placing less
demand on your water heater, you’ll prevent undue stress that could
cause its components to wear out prematurely. You can check the temperature
of your home’s hot water by running the hot water from the faucet
nearest the water heater for at least one minute. After this time, fill
a mug with hot water from the tap and use a candy or cooking thermometer
to check the temperature and set your water heater accordingly.
Know Your Water Pressure
Your home’s water pressure also plays a role in the longevity of
your water heater. Excessively high water pressure can stress your water
heater, causing it to wear out quickly and spring leaks that require replacement
to address. You can
test your home’s water pressure using a water pressure gauge, which can be attached to an outdoor hose
bib or faucet to read the pressure of the water in your home’s plumbing
pipes. If your pressure is too high, a plumber can install a device to
reduce it, thus reducing stress on your water heater as well.
Clean Your Tank
While flushing your water heater monthly can help to reduce mineral buildup
inside the tank, it’s also important to clean your tank periodically
using a solution designed to remove lime, rust, and calcium from the tank’s
inner walls. Especially if you are moving into a home and aren’t
sure when the water heater was last flushed, this step can return your
water heater’s tank to a condition much closer to pristine. To clean
your tank, you’ll need to purchase a CLR (calcium, lime, and rust)
cleaning solution, which is typically available in gallon-sized containers.
Disconnect your water heater from its power and water sources and drain
a few inches of water, then pour the cleaner slowly into the inlet pipe.
Let the cleaner sit in the tank for at least five hours, then rinse your
water heater by draining all the water and running fresh water in, allowing
the tank to drain for several minutes to flush away any remaining sediment
and cleaner. Finally, close the outlet valve and fill the tank, then open
all your home’s hot water taps to release any trapped air from the
system before restoring the power to your water heater once more.
