A residential water heater contributes to as much as 30 percent
of a household's energy cost - second only to the expense of a
home's heating and cooling system. Selecting the right water heater
- one that is efficient and the right capacity - can dramatically
impact your monthly energy bill.
Other ways to lower your energy bill include:
- Always wash full loads of laundry, using cold water whenever
- Always run full loads in the dishwasher.
All water heaters carry standard Energy Guide labels. Use this
government-regulated information to compare the performance and
operating costs of different models.
What It Means
Model: The model number of the unit.
First Hour Rating: Amount of usable, stored
water available combined with the amount of water the unit can heat
in one hour. This rating demonstrates the unit's capacity during
Energy Use Per Year: Estimated measure of the
energy required to operate the unit for one year, measured in
Therms, Gallons or Kilowatt Hours, depending upon fuel type. The
Energy Guide lets you compare an individual model's performance
against an acceptable range of other models. More efficient units
will require less energy.
Estimated Annual Operating Cost: Dollar amount
required to operate the unit for one year. More efficient units
will cost less to operate.
National Average Cost per Therm, Gallon or KWH:
A standardized dollar figure representing the cost of one Therm,
Gallon or Kilowatt Hour of power. A unit's actual cost will vary,
depending on local utility rates and usage.
