Water heaters are tanks, usually located in a basement or garage, in which water is heated by either electricity or gas for use in the home. Both types of water heaters work in similar ways, although a gas heater uses a burner with a flame, and an electric water heater has electric elements used to heat water in the tank. In general, you should make sure that the water heater thermostat in your Sun City West, Arizona, home is set between 120 and 135 degrees F. Discover why this temperature setting range can promote optimum energy efficiency for your water heater.

When to Set a Lower Temperature

The U.S. Department of Energy notes that while some water heater manufacturers set thermostats to 140 degrees, most households generally need a setting of only 120 degrees. Not only does this temperature setting reduce the amount of mineral accumulations and corrosion in the water heater and pipes, but it also helps to prevent accidental scalding for households with small children.

Additionally, as the U.S. Department of Energy notes, a water heater set at 140 degrees can waste between $31 and $61 annually in standby heat losses and greater than $400 in heat demand losses.

When to Set a Higher Temperature

For people with suppressed immune systems or respiratory diseases, a temperature setting of higher than 120 degrees may be beneficial. A temperature of more than 122 degrees can help curtail the growth of certain strains of bacteria responsible for Legionnaires’ disease. These bacteria can be found in soil and in sources where water is present, such as air conditioning ducts, water storage tanks such as water heaters, and natural bodies of water.

While 120 degrees is an optimal temperature setting for energy savings and accidental scalding prevention, homeowners should consider their specific water heating requirements to determine the proper temperature setting.
