Warm Water and Energy Waste

Did you know that the water heater can account for up to a quarter of a home's energy use? As weather cools, you can reduce heat-loss from your water heater by insulating the tank and hot water pipes. Adding insulation to the water heater tank can reduce heat-loss by between 25 and 45 percent, saving four to nine percent on water heating costs. Well-insulated pipes also reduce heat loss and can raise water temperature by two to four degrees, allowing you to lower your hot water temperature setting to save even more energy.

You can purchase inexpensive, pre-made blankets or jackets for your hot water heater tank from some utility companies or your local home improvement store - look for an insulating value of "R-8." Insulate hot water pipes using insulation wrap, fiberglass tape strips, or pipe sleeves for at least three feet from the heater (if you have a gas heater, keep insulation at least six-inches from the flue). Once you have insulated, consider lowering the water heater temperature - just ten degrees can save three to five percent on energy costs.
