Energy Star to Increase Water Heater Criteria



BOSTON  June 7, 2010 — This fall, the
Energy Star program will increase the minimum energy factor (EF) for gas storage
water heaters from 0.62 to 0.67. The increase in criteria, which will go into
effect on September 1, 2010, will bring additional 0.67 EF models to the
marketplace, offering homeowners even greater water heating efficiency.


“Energy Star seeks to keep its
product criteria relevant by keeping pace with changing technologies in the
marketplace,” said Steve Ryan, with the Energy Star program at the Environmental
Protection Agency. “In a recent poll, 77 percent of people are aware of the
Energy Star label and see the value in it. We work to keep the brand meaningful
by making sure it continues to indicate cost effective savings with no loss of
amenity. Storage water heaters are becoming more efficient, and this change
recognizes that fact.”


Water heaters that meet the
increased criteria offer homeowners significant savings in gas consumption even
when compared to today’s 0.62 EF models, providing up to 14 percent greater
savings than a conventional gas model. According to Energy Star calculations,
0.67 EF models only consume 224 therms per year. Gas storage heaters with a 0.62
EF consume 242 therms annually, saving up to 7.3 percent more than a
conventional model.


Several gas storage heaters with
a 0.67 EF are currently available, including many new products recently
developed in preparation for the upcoming change. There are also a number of
other water heater models that carry the Energy Star label, including electric
heat pump, solar thermal and tankless units.
