Get a handle on hot water use

Keeping the faucet handle in the “Cold” position saves energy
It’s cold and flu season, when we’re all encouraged to avoid illness by washing hands. Here’s a tip to keep energy from going down the drain with the germs.
If you briefly run water from a bathroom or kitchen faucet, set the handle to use only cold water. You may not realize it, but whenever the faucet handle is not in the cold position, a portion of the water you are using is passing through and is heated by your hot water tank. In the short time it takes to wash your hands, hot water leaves the water heater, but is usually shut off before it gets to you. This previously heated water then sits in the pipes and cools down to the same temperature as the inside of your house. You end up washing your hands or brushing your teeth with water that is the same temperature as the inside of the house.
So regardless of whether the faucet is set in the cold, warm or hot position, the temperature of the water leaving the faucet does not change until hot water has had time to travel from the water heater to the faucet.
If you prefer warm water for taking a shower (most do, of course) or washing your hands, you can save some water — and cut the time in half that it takes to get warm water — by turning the faucet to hot, then adjusting the handle when the warm water arrives at the faucet. When you are done, be sure to turn the faucet back to cold so that brief uses do not waste energy.
