3 Ways to Make Your Water Heater Last

Replacing a tank water heater can be expensive, but if you maintain your heater, it can last much longer. With good maintenance, many tank water heaters can last 15 years or longer. However, homeowners often forget about water heater maintenance, which can shave years off the lifespan of their appliance.

Water heaters wear out from the constant heating and storage of water. This puts stress on the metal tank and the heating elements, especially due to the minerals that are released from the water. There are simple ways to reduce this stress and prolong the life of your water heater, including these three tips:

  1. Keep 120-degree temperature. You want your water to be hot enough to kill bacteria, but not overly hot which can put extra stress on the tank and run up your energy bills. Keep your temperature at 120-degrees, a safe level for your needs.
  2. Drain the tank annually. Releasing the minerals and sediment in the tank can help reduce corrosion and help keep the heating elements efficient. You can do this yourself or your local plumber can do this as part of an annual service.
  3. Replace sacrificial anode rod. There are sacrificial anode rods in tank water heaters. These are meant to attract minerals to reduce corrosion occurring in the tank but will slowly disintegrate as they do their job and need replacement.

By doing these three maintenance items, along with repairs as needed, you can get more years of life from your tank water heater. Make it easy by scheduling annual service for your water heater with a local plumber. They can drain your tank and check the anode rods and other parts, replacing components as needed to keep your water heater maintained.

Water Heater Temperature

You can save money on your energy costs by setting the temperature on your standard holding tank type water heater a few degrees lower.  According to the Environmental Protection Agency, lowering your water heater temperature setting by ten degrees can save three to five percent on your water heating costs.

Most water heater come from the factory set at 140 degrees, but it is easy to lower the setting just by turning the thermostat dial down to the desired temperature. Check your owner’s manual for instructions on adjusting the thermostat on your water heater.  On a gas water heater, the thermostat is usually found at the bottom of the tank near the pilot light.  The thermostat on an electric water heater is usually behind a small panel and there may be two thermostats, an upper an a lower.

Most households don’t need water heated to 140 degrees and water that hot can pose a risk scalding.  120 degrees is usually a good setting for most households and it also slows the development of mineral build up and corrosion.  Not only will you save money on your energy bill, but your water heater will last longer.

If you have a dishwasher, check the owner’s manual before you lower the temperature setting on your water heater.  Some dishwashers require water temperatures of 130 degrees or more to clean properly.  Dishwashers with heat boosters are less sensitive to lower hot water temperatures.

The one disadvantage of lowering the temperature on your water heater is that you may run out of hot water sooner.  Since the water is not as hot, you will mix less cold water with the hot water to get the desired shower or bathwater temperature.
