DOE announces water heater Energy Star program for 2009

摘要

The U.S. De partment of Energy has announced the final criteria for its water heater Energy Star program that will begin next January. Water heating represents between 13% and 17% of national residential energy consumption, making it the third largest energy end use in homes, behind heating and cooling and kitchen appliances, DOE said in its Final Criteria Analysis, released in April. As homes become more energy efficient, DOE noted, the percentage of energy used for water heating steadily increases.
