Decreasing the temperature on your water heater can help save energy and reduce utility bills. To adjust your water heater temperature, locate the thermostat and set it to a lower temperature, typically between 120°F (49°C) and 140°F (60°C). This simple adjustment can enhance safety and efficiency in your home.
Why Adjust Your Water Heater Temperature?
Lowering the temperature on your water heater can offer several benefits:
- Energy Savings: Reducing the temperature can decrease energy consumption, leading to lower utility bills.
- Safety: A lower temperature minimizes the risk of scalding, especially important for households with children or elderly individuals.
- Extended Lifespan: Operating at a lower temperature can reduce wear and tear on the water heater, potentially extending its lifespan.
How to Adjust Your Water Heater Temperature
Identifying Your Water Heater Type
Before adjusting the temperature, identify whether you have an electric or gas water heater, as the process differs slightly for each.
- Electric Water Heaters: Typically have thermostats behind panels on the side of the tank.
- Gas Water Heaters: Usually have a dial near the bottom of the tank.
Steps to Decrease Temperature on an Electric Water Heater
- Turn Off Power: Locate your home’s circuit breaker and switch off the power to the water heater.
- Access the Thermostat: Remove the access panel and insulation to reach the thermostat.
- Adjust the Temperature: Use a flathead screwdriver to turn the thermostat dial to the desired temperature, ideally between 120°F and 140°F.
- Reassemble the Panel: Replace the insulation and access panel securely.
- Restore Power: Turn the power back on at the circuit breaker.
Steps to Decrease Temperature on a Gas Water Heater
- Locate the Dial: Find the temperature dial on the front of the water heater.
- Adjust the Dial: Turn the dial to the desired temperature setting, usually marked as "Low," "Medium," or specific degrees.
- Check the Temperature: Allow a few hours and then test the water temperature at a faucet to ensure it’s at the desired level.
Recommended Temperature Settings
The U.S. Department of Energy recommends setting your water heater to 120°F (49°C) for optimal energy savings and safety. This temperature is sufficient for most household needs, including bathing, cleaning, and cooking.
Benefits of Setting at 120°F
- Energy Efficiency: Reduces energy usage by up to 10% compared to higher settings.
- Safety: Lowers the risk of scalding while still providing hot water for daily tasks.
- Bacterial Control: Adequate to prevent bacterial growth, such as Legionella, in the tank.
Potential Risks of Incorrect Temperature Settings
- Scalding Hazard: Temperatures above 140°F can cause burns within seconds.
- Energy Waste: Higher temperatures increase energy consumption and utility costs.
- Bacterial Growth: Temperatures below 120°F may not effectively control bacteria.
