If your hot water isn’t as hot as you’d like, you might need to adjust the temperature on your water heater.
Follow these simple steps to safely turn up the temperature on your water heater.
Step 1: Gather the Necessary Tools
Before you begin, make sure you have the following:
- A flathead screwdriver (for electric water heaters)
- Thermometer (optional, to check water temperature)
Step 2: Determine Your Water Heater Type
Identify whether you have a gas or electric water heater. The method for adjusting the temperature varies slightly depending on the type.
Step 3: Locate the Temperature Control
For Gas Water Heaters: The temperature control is usually a dial located on the front of the gas control valve, near the bottom of the tank.
For Electric Water Heaters: The thermostat is typically found behind an access panel on the side of the tank. You may need to remove a small cover and some insulation to access the thermostat.
Step 4: Adjust the Temperature
For Gas Water Heaters: Simply turn the dial to increase the temperature. A setting of 120°F is recommended for most households, as it’s hot enough for daily use but not so hot that it poses a scalding risk.
For Electric Water Heaters: Use a flathead screwdriver to turn the thermostat dial. Most electric water heaters have two thermostats (one for the upper element and one for the lower). Adjust both to the same temperature setting for consistent heating.
Step 5: Check the Temperature
After adjusting the temperature, wait a few hours and then check the hot water at a faucet using a thermometer. If the water is too hot or not hot enough, you can readjust as necessary.
Step 6: Replace Any Covers and Insulation
For electric water heaters, make sure to replace the insulation and access panel after adjusting the thermostat to ensure the unit is properly protected.
Final Tips
Turning up your water heater’s temperature can help provide hotter water for showers and other uses, but be cautious not to set it too high, as this can increase the risk of scalding and higher energy bills.
