Water Heater Temperature Safety

Water heaters are a deeply important part of your home, but most homeowners don’t really think twice about them after the installation. Unfortunately, installations performed before you moved in or by professionals who don’t take the time to check the unit is functioning can lead to improper water heater temperatures.

The right temperature could easily be the difference between scalding hot water and, on the other hand, water that doesn’t stay hot long enough to discourage the growth of harmful bacteria. How can you know if your water heater temperature is the right one? Ask yourself the following questions:

  • Has the water heater’s base temperature been changed since it was first installed? Water heaters used to have a factory setting of 140°F, which can cause scalding in 5 seconds.  Some heaters get set entirely too high at 160°F. That temperature will cause third degree burns in a mere second. Today, water heaters are factory set to 122.5°F–a much safer temperature!
  • If it has been changed, is it possibly set too low? Setting your water temperatures too low isn’t any better than setting it too high. Low temperatures, between 90 to 115°F, can encourage the growth of bacteria that could make you or your family sick. Temperatures that low need to be avoided.

So What is the Best Water Heater Temperature Setting? 

Most experts agree that the ideal setting for safety and personal comfort is 120°F-125°F. It’s a high enough setting to discourage bacterial growth, but not so high that you need to worry about possible injuries. As an added bonus, you’ll also save on your energy bills by lowering the temperature. Taking the time to double-check and ensure your water heater is set within a safe range of temperatures also lets you get a bit more familiar with this overlooked but integral part of your home.
