Efficient Water Heater
A Hidden Expense
Consumers tend to overlook the expense of heating water for their daily needs, even though 15% of each household's energy dollar goes to heat water. Using less hot water is one of the easiest ways to decrease your water heater's energy output and lower your bills.

Incentives & Services
If your water heater is more than 10 years old, consider replacing it with a new unit (the last two digits of the heater's serial number usually represent the year of manufacture). Some utilities offer rebates on new, energy-efficient models. Today's water heaters are vastly more energy efficient than older models. Water heater efficiency is reported in terms of the energy factor (EF). The higher the EF, the more efficient the water heater.
If you are thinking about replacing your old water heater to save on heating costs, or you want to learn more about high efficiency water heaters, read ENERGY STAR's guide.
