Adjusting Your Water Heater Temperature

Adjusting Your Water Heater Temperature

Although most new water heaters come set at 120 degrees Fahrenheit, the ideal water heater temperature setting ranges from 120 degrees Fahrenheit to 140 degrees Fahrenheit. This range exists for a reason—a setting lower than 120 degrees Fahrenheit creates a risk for bacteria to grow inside the appliance. On the other hand, a setting higher than 140 degrees Fahrenheit increases the risk of scalding. There are several reasons why your water heater temperature setting may drift from the ideal range, including a malfunctioning thermostat and sediment buildup.

In this guide, we will explain how to adjust the water heater temperature in electric and gas water heaters. We are a top-rated plumbing service that specializes in water heater installation, plumbing repairs, and water heater maintenance.

How To Adjust The Temperature On An Electric Water Heater

This is a fairly simple process that doesn’t require any professional expertise or skills. All you need to do is refer to your water heater’s manual for specific instructions. If you’re in doubt, it’s a good idea to seek help from a plumber that specializes in water heater repair and replacement. Here are the general steps to follow to adjust the temperature on an electric water heater.

  • Step 1: Turn off the power at the circuit breaker controlling your water heater.
  • Step 2: Locate the access panel near the base of the unit—use a screwdriver to remove the screws holding the panel.
  • Step 3: Once the panel is open, you’ll notice a dial or knob on the thermostat with markings like “Low,” “Medium,” or “High.” Use a screwdriver to adjust the dial to your desired temperature setting.
  • Step 4:  Screw the panel back in place and turn the power back on.

How To Adjust The Temperature On A Gas Water Heater

Adjusting the temperature on a gas water heater is mostly the same as it is for an electric model. These are the steps to follow:

  • Step 1: Turn the gas shut-off valve clockwise to stop gas flow to the unit. This is a very important step that you want to handle with a high level of precision to avoid a gas leak.
  • Step 2: Look for the temperature control dial near the bottom of your water heater—it’s usually a knob or a cylindrical dial with temperature markings or a digital display.
  • Step 3: Adjust the dial or knob to your desired temperature setting (120 degrees Fahrenheit to 140 degrees Fahrenheit).
  • Step 4: Screw back the access panel in place, turn the power back on, and continue enjoying a continuous supply of hot water.
