Water Heating

Cut down on water heating costs

Hot water faucet

Install energy-efficient showerheads – Use efficient showerheads and faucet aerators. They reduce the amount of water released by up to 50 percent, with almost no noticeable difference in pressure.

Adjust the temperature – Set the water heater temperature to 120°F. Some dishwashers require the temperature to be slightly higher. Consult your owner's manual. Caution: Turn the power off at the circuit breaker before changing the temperature on a water heater.

Fix leaky faucets – A dripping faucet can waste
6 to 10 gallons (23-38 liters) of water per day. Repairs can be as simple and inexpensive as replacing a worn-out washer.

Take showers – The average bath uses twice as much hot water as a five-minute shower.

Insulate pipes – If pipes are exposed beneath your home or in an unheated garage, insulate them with special pipe-insulating foam. This will help keep cold water pipes from freezing and hot water pipes hot.

Turn off the faucet – Many of us tend to leave the faucet running while we wash dishes, brush our teeth or shave. Turning on the faucet only when necessary can save thousands of gallons of water a year, not to mention the energy needed to heat it.

Buy an energy-efficient model – When shopping for a new water heater, look for an energy factor equal to or better than .95 EF for a 50-gallon electric or .62 for a 40- to 60-gallon gas model. Check for cash incentives for heat pump water heaters.
