ENERGY STAR To Increase Minimum Gas Water Heater Efficiencies
Wednesday, June 9th, 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. Sponsors of the Coalition for ENERGY STAR Water Heaters (CEE)—A. O. Smith, Bradford White, Rheem and Rinnai—offer many of these models.

Boulder is seeking a unique way of mending the debate between landlords and tenants on energy-efficiency — a single program for homeowners to meet proposed new standards.
The American Clean Skies Foundation (ACSF), together with the UN Foundation and the Worldwatch Institute, today hosted a major side event in Copenhagen focusing on the ways natural gas — and, in particular, the discovery of vast reserves of unconventional, or shale gas — can accelerate the transition to a global low-carbon economy. Natural gas can generate electricity with 50-70 percent less CO(2) than coal per BTU. As is the case in the U.S., many other countries have also recently discovered very large new unconventional reserves of natural gas, primarily in deeply buried shale rock formations.
Dozens of home energy monitors are coming to market, but nobody knows whether only hybrid Prius owners will use them.
Every day it’s becoming clear to more and more Americans that our continued over reliance on foreign oil is not just an environmental disaster but an economic disaster for this country as well. People appreciate that while we will have great sources of renewable fuel down the road, we need something now. And what is available now and has been proven to be in great abundance in the United States is natural gas.
