Energy Star Increases Water Heater Criteria

June 11, 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, which will offer homeowners even greater water heating efficiency. The increase will go into effect on September 1, 2010.

“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 the current 0.62 EF models, providing up to 14 percent greater savings than a conventional gas 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.

Plumbers can check with their distributors and local utilities on the availability of new 0.67 EF gas storage models and rebate offers in their area. Visit the Coalition online for more information.
