Try these low- or no-cost tips to boost your household’s energy efficiency:

The Water Heater

  • Periodically remove sediment that builds up in the bottom of your water heater. Draining water until it appears clear removes sediment and improves your water heater’s efficiency. (Follow manufacturer’s instructions.)
  • Set the temperature on low (120°) and use warm instead of hot water for washing clothes and dishes. However, a temperature lower than 120° may result in increased detergent use. (Note: Dishwashers without booster heaters may require a water temperature of 140°. (Check manufacturer’s instructions.)
  • Insulate your electric water heater. If it feels warm to the touch, you may not have enough insulation. You can wrap the sides with an insulation blanket to reduce heat loss. This insulation could reduce energy use by 5% to 8%.
  • Ensure maximum efficiency of your oil-fired water heater. Have a qualified service person inspect the flame, damper, and stack temperature.
