Water Heating

  • Take short showers instead of baths. It takes more energy to heat bath water than to heat a short shower.
  • Insulate your electric hot-water storage tank, but be careful not to cover the thermostat. If your tank uses natural gas or oil, be careful not to cover the water heater's top, bottom, thermostat, or burner compartment. Follow the manufacturer's recommendations; when in doubt, get professional help.
  • Install a low-flow aerating showerhead and faucet and it can cut your usage up to 50%.
  • Repair leaky faucets promptly; a leaky faucet wastes gallons of water in a short period of time.
  • Lower the thermostat on your water heater; water heaters sometimes come from the factory with high temperature settings, but a setting of 120°F provides comfortable hot water for most uses.
  • Drain a quart of water from your water tank every 3 months to remove sediment that impedes heat transfer and lowers the efficiency of your heater. The type of water tank you have determines the steps to take, so follow the manufacturer's advice.
  • Look for the ENERGY STAR label when buying a new water heater.
  • Consider installing a drain water waste heat recovery system or a tankless water heater and save up to 35%.
