Making Your Water Heater More Energy Efficient
- If you have a water heater set at 140º F, turn the temperature down to 120º F (medium setting on a gas heater dial), and you’ll cut your water heating costs by 6 to 10 percent. For exceptionally soiled clothing, diapers, or when someone is ill, you may want to turn it back up when laundering their items. Some water heaters use a timer control to manage the water temperature - much like automatic thermostats manage the heating or cooling temperature for your home.
- Turn the water heater down further if you are away for an extended time.
- Insulate the hot water heater if it is warm to the touch. Check the operating manual for specific directions on how to insulate gas and electric water heaters.
- Insulate the hot and cold water pipes at the water heater for at least 6 to 10 feet. Insulate all exposed water pipes for even more efficiency to prevent heat loss and heat gain.
- Read the EnergyGuide label to compare similar models and capacities when buying a new water heater. Look for the ENERGY STAR® label.
Energy Efficient Hot Water Use
- Install low-flow faucets and shower heads and take shorter showers.
- Fix faucet leaks. One drip can waste up to 48 gallons of water a week, and waste energy from hot water.
