Turning down the hot water tank temperature can save energy and reduce the risk of scalding. To adjust the temperature, locate the thermostat on your water heater, which is usually found on the side of the tank. Rotate the dial to the desired setting, typically around 120°F (49°C) for optimal efficiency and safety.
Why Adjusting Hot Water Tank Temperature Matters
Adjusting your hot water tank’s temperature can have several benefits, including energy savings, safety improvements, and extending the lifespan of your appliance. By setting the temperature to a lower level, you can reduce energy consumption and lower utility bills. Furthermore, maintaining a moderate temperature helps prevent scalding accidents, especially in households with children or elderly individuals.
How to Safely Lower the Temperature on Your Hot Water Tank
What Tools Do You Need?
Before you start, gather the necessary tools to ensure a smooth process:
- Screwdriver: To remove the access panel if your hot water tank has an electric thermostat.
- Thermometer: To verify the water temperature after adjustment.
Steps to Adjust the Temperature
-
Turn Off Power: For electric water heaters, switch off the power at the circuit breaker. For gas water heaters, set the control to the "pilot" setting.
-
Locate the Thermostat: On electric models, remove the access panel and insulation to find the thermostat. Gas water heaters typically have a visible dial near the bottom.
-
Adjust the Temperature: Use a screwdriver to rotate the thermostat dial to the desired temperature, usually around 120°F (49°C).
-
Reassemble and Restore Power: Replace any panels and insulation, then turn the power back on or adjust the gas control to the "on" position.
-
Check the Temperature: After a few hours, use a thermometer to test the water temperature at a faucet to ensure it aligns with your setting.
Benefits of Lowering Your Hot Water Tank Temperature
- Energy Efficiency: Reducing the temperature can decrease energy usage by 3-5% for every 10°F reduction.
- Safety: Lower temperatures reduce the risk of scalding. The U.S. Consumer Product Safety Commission recommends 120°F to minimize burn injuries.
- Appliance Longevity: Operating at lower temperatures can prevent mineral buildup and reduce wear on your water heater.
