Hot Water



  • Save water costs by turning off the tap when you shave, wash or brush your teeth.
  • Many hot water heaters are factory-set for 140° F. That’s a lot higher than you need. Reset it to 120° F.
  • If you have an off-peak electric hot water heater, set your bottom thermostat at 135° F and the top thermostat at 125° F for maximum efficiency.
  • If you are buying a new electric hot water heater, make sure to buy the highest efficiency energy rating available.
  • When installing a new hot water heater, locate it in a warm place rather than an unheated garage or basement, if possible.
  • Wrap your hot water heater with an insulation blanket, if allowed by manufacturer’s recommendation.
  • Turn off your electric water heater when you leave home for extended periods, such as vacations.
  • Take showers instead of baths. A three minute shower uses about half the water of a bath.
  • In the summertime, take warm or even cold showers whenever possible.
  • Turn off the hot water tap each time you rinse dishes, or better yet - scrape, don’t rinse. Letting the tap run wastes up to 30 gallons per meal.
  • Replace washers on faucets that drip. A leaky faucet can waste 2,500 gallons of hot water per year.
  • Insulate at least ten feet of hot and cold water pipes attached to your hot water heater.
  • Install water-saving low-flow shower heads and sink aerators.
  • It is important to keep your hot water system properly maintained. Once or twice a year, drain a bucket of water out of the bottom of the heater tank because it is sometimes full of sediment. The sediment insulates the water in the tank from the heating element, which wastes energy.
  • Repair leaky faucets promptly. A steady drip of hot water can waste many gallons of water per month, plus the energy needed to heat the water.
  • Set your water heater at 120 degrees. Overheating your water beyond 120 degrees can be wasteful and unsafe. By lowering your water temperature to 120 degrees or less, you can save up to $25 annually if you use an electric water heater or $18 annually if you use a gas water heater.
