Water heaters are essential fixtures in any household, but most people don’t know the basics of how they function. The water heater is used to heat the water coming through the pipes up into your home. Without it, you can’t take a hot shower or wash the dishes. Homeowners should know which temperature to set this device and how to identify issues that require assistance from a professional.

What Is the Best Temperature to Set Your Water Heater?

The default setting on a water heater from most manufacturers is around 140 degrees Fahrenheit. If you’ve never touched the temperature on yours, it’s probably set to this temperature. The Department of Energy is advising consumers to lower the temperature on their water heater to 120 degrees Fahrenheit for energy efficiency. If the water that comes out of the faucet is too hot after warming up for a few moments, it’s a sign that the temperature may be set too high.

What Are the Risks of Having the Temperature Too High or Too Low?

If the temperature of your water heater is too high, it increases the risk of scalding for children and adults using faucets and showers. Scalding water can cause serious burns and injuries to your skin. If the temperature is set too high, it can waste anywhere from $36 to $61 every year in standby heat losses.

If your water heater is set at or below 120 degrees Fahrenheit, it could be dangerous for people with suppressed immune systems. If the water isn’t hot enough, there’s a risk of legionellae bacteria growth.
