Energy Efficient Water HeatersIf you aren't ready to purchase one of the new energy efficient water heaters, there are ways to conserve energy with the one you have. In the average home, 10%-15% of the utility bill is from hot water usage.
3 Ways to Shave Your Utility Bill by up to 30%Transforming your current unit to a more energy efficient water heater will reduce your utility bills and help out the environment. Even when you aren't using hot water, the unit is working to keep the water at a pre-set temperature. After your hot morning shower, cold water fills the tank. The system heats the newly added water for your next load of laundry.
Turn Down the TemperatureTurn down the temperature on the hot water heater and save up to 10% in energy costs each year. Some manufacturers set thermostats as high as 140 degrees F. This high temperature is usually unnecessary and can cause scalding, which is a safety concern if there are children in the household.Reducing the thermostat to 120 degrees F is usually ideal, but check the owner's manual first. Turning down the temperature slows build-up and corrosion, giving the hot water heater a longer life.

Water heaters can also lose heat if they are located in a cold space, such as an unfinished basement. To make sure your unit is running at an optimal level, place your hand on the outside of the tank. If it feels warm to the touch, adding insulation will save money and energy. For a more energy efficient water heater, consider a water heater blanket. They cost around $15 and are easy to install. According to the U.S. Department of Energy, insulation can reduce stand-by heat loss by 25%-45%. To insulate your gas or electric hot water heater, see their instructions.
Insulate the PipesIn most homes, the hot water pipes are left forgotten and uninsulated. If your pipes are located in colder areas, warm to the touch, or are covered in excess moisture, it's beneficial to insulate them.According to the U.S Department of Energy, insulating water pipes does several things: it raises water temperature by 2-4 degrees F more than uninsulated pipes, it helps conserve water because it takes less time for hot water to reach the faucets, and it allows you to lower the temperature on the hot water heater. For more information, see their instructions on insulating hot water pipes.
Buying New: Energy Star Water HeatersIf you do buy new, consider an Energy Star water heater. Early in 2009, five types were sealed with the Energy Star logo. Gas heaters include high efficiency, tankless, and gas condensing models. Some electric and solar water heaters also carry the Energy Star seal. For more information, see Five Types of Energy Star Water Heaters.
