Lowering the temperature of the water heater

Top 3 reasons to lower your water heater temperature

When the temperatures outside drop, there’s nothing better than a hot shower to get rid of the winter chill. However, there are important reasons why you should lower the temperature of your home’s water heater. Here are three reasons why you should consider lowering the temperature of your water heater and how to do it.


Depending on the type of water heater you have, some are automatically set at 140 degrees. At this temperature, you can get burned. Consider turning your water heater down to 120 degrees to minimize this risk.


According to the Department of Energy, you can get up to 22% energy savings when you turn down the temperature of your water heater. The savings come from reduced standby losses, which is the heat lost from the water heater to the environment.

The average household with a water heater temperature set at 140 degrees loses up to $61 a year in standby heat loss. If you choose to lower your water heater temperature, additional savings can come from the reduced energy needed to heat the same amount of water to 120 degrees instead of 140 degrees.

Experts also recommend turning your water heater down to its lowest settings if you plan to be away for an extended period of time.


Sediment buildup in your home’s water heater is a major factor in water heater tank corrosion that can shorten the life of your unit. Water temperatures set above 120 degrees contribute to hard water mineral sediment build-up. Sediment build-up can also make your water heater work harder and require more energy to operate.


Lowering the temperature of your water heater is fairly simple.

  • Read your water heater’s instruction manual to find the thermostat and operating instructions for your water heater. 
  • Also, find the current temperature of your water at its hottest point by testing a faucet located farthest from the water heater with a thermometer.
  • Recall your water heater if the water temperature is above 120 degrees.
  • Retest the same faucet after waiting a few hours.
  • Repeat the steps to bring the water to the desired temperature.
  • If you’re looking to save money on your energy bill or extend the life of your water heater, consider lowering the temperature of your water heater. You can also consider a tankless water heater.
  • Tankless water heaters do not store heated water, but rather produce hot water only when needed.
