Turning down the heat on a hot water tank is a simple yet effective way to save energy and reduce utility bills. By adjusting the thermostat on your water heater, you can maintain a comfortable water temperature while minimizing the risk of scalding. Here’s a step-by-step guide to help you safely lower the temperature on your hot water tank.
How to Adjust the Temperature on a Hot Water Heater
-
Locate the Thermostat: Most water heaters have a thermostat located behind an access panel. For electric heaters, you may need to remove a small panel with a screwdriver. Gas heaters usually have a thermostat dial near the bottom of the tank.
-
Turn Off the Power: Before making any adjustments, ensure the power to the water heater is turned off. For electric heaters, switch off the breaker in your electrical panel. For gas heaters, turn the gas control knob to the "pilot" setting.
-
Adjust the Thermostat: Use a flathead screwdriver to turn the thermostat dial to your desired temperature. A safe and energy-efficient setting is typically around 120°F (49°C). This temperature is hot enough for most household needs and reduces the risk of scalding.
-
Replace the Access Panel: After adjusting the temperature, replace the access panel securely. For electric heaters, turn the power back on at the breaker. For gas heaters, turn the gas control knob back to the "on" position.
-
Test the Water Temperature: Allow a few hours for the water to reach the new temperature. Then, test the water temperature at a faucet to ensure it meets your needs.
Why Adjust Your Hot Water Heater Temperature?
Adjusting your hot water heater’s temperature can lead to several benefits:
- Energy Savings: Lowering the temperature by just 10°F can reduce energy costs by 3-5%.
- Safety: A temperature of 120°F helps prevent scalding, especially important for households with children or elderly members.
- Extended Appliance Life: Reducing the temperature can decrease mineral buildup and corrosion, extending the lifespan of your water heater.
