Turning down the heat on your hot water tank is a simple yet effective way to save energy and reduce your utility bills. By adjusting your water heater’s temperature settings, you can also prevent scalding and extend the lifespan of your appliance. 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 Your Hot Water Tank
Most hot water tanks have a thermostat that allows you to control the temperature. Here’s how you can adjust it:
-
Locate the thermostat: Typically, the thermostat is found on the side of the tank. For electric water heaters, you might need to remove an access panel. Gas water heaters usually have a visible dial.
-
Turn off the power: If you have an electric water heater, switch off the power at the circuit breaker to ensure safety. For gas heaters, turn the gas control knob to the "pilot" setting.
-
Adjust the thermostat: Use a flathead screwdriver to turn the thermostat dial. A safe and energy-efficient setting is around 120°F (49°C).
-
Replace any covers: If you removed an access panel, make sure to replace it securely.
-
Turn the power back on: Restore power to your electric water heater or turn the gas control knob back to the "on" position for gas heaters.
-
Test the water temperature: Allow a few hours for the water to adjust to the new setting, then test it at a faucet.
Why Lower Your Hot Water Tank Temperature?
Lowering the temperature on your hot water tank can bring several benefits:
- Energy savings: Reducing the temperature from 140°F to 120°F can save you up to 10% on water heating costs.
- Safety: Lower temperatures reduce the risk of scalding, especially important for households with children or the elderly.
- Extended appliance life: Operating at lower temperatures can prevent mineral buildup and corrosion, prolonging the life of your water heater.
Common Questions About Hot Water Tank Temperature
What Temperature Should a Hot Water Tank Be Set to?
For most households, setting the hot water tank to 120°F (49°C) is ideal. This temperature is hot enough for daily use and prevents bacteria growth, such as Legionella.
How Can I Check My Hot Water Temperature?
To check your hot water temperature, use a thermometer. Run hot water at the faucet for a few minutes, fill a cup, and measure the temperature. Adjust the thermostat if needed.
Can Lowering the Temperature Affect Water Pressure?
Lowering the temperature typically does not affect water pressure. However, if you notice a change, it might be due to other issues like sediment buildup or a malfunctioning valve.
Is It Safe to Adjust the Water Heater Myself?
Yes, adjusting the thermostat is generally safe if you follow proper procedures. Always ensure the power is off before making adjustments to prevent electric shock or gas leaks.
How Often Should I Check My Water Heater Temperature?
It’s a good practice to check your water heater temperature annually. This ensures the settings are optimal for energy efficiency and safety.
Additional Tips for Maintaining Your Hot Water Tank
- Regular maintenance: Flush your tank annually to remove sediment buildup.
- Insulate the tank: Use a water heater blanket to improve efficiency.
- Inspect for leaks: Regularly check for any signs of leakage or corrosion.
