HOW TO:  Adjusting the temperature of your water heater

Whenever you have a new water heater installed, it will typically be set to 120 degrees. This is the standard. This temperature helps prevent scalding, and also saves energy. But just because something is recommended doesn’t mean there won’t be instances where you need to change it. Here are a few tips on how to adjust yours:

Gas water heaters
If you have a gas water heater, you’re in luck because adjusting the temperature is pretty simple. Most models will have a knob at the bottom that adjusts the temperature. Simply turn the knob to whatever setting best suits your needs. In some cases the knobs will have descriptions instead of actual temperatures. In this case, the warm setting will typically be between 90 to 110 degrees, while the hot setting will usually be around 140 to 150 degrees.

Electric water heaters
Electric water heaters are a bit trickier. The first thing you want to do is ensure that power to your water heater is turned off. To do this you’ll want to turn off the breaker for your water heater.

If you have a double element water heater, you’ll want to remove both access panels on the front of the tank. For single element heaters, you only need to remove the lower panel. Once removed, you’ll need to remove the insulation to get to the thermostat. Once the insulation is removed, you should see the thermostat, and the temperature your water is set at. To adjust this temperature, you’ll need to use a flat-head screwdriver, and turn the screw on the dial to your desired temperature. Once you have turned your heater to the desired setting, replace all the coverings and turn the power to your heater back on.

Tankless Water Heater
You have it easy. Adjusting a tankless water heater is usually as simple as pressing a button on your front panel command center or remote control.
