Residential water heating represents the second largest consumption of energy in the home, right behind heating and cooling. For many years, there was no official ENERGY STAR® program for water heaters. But, beginning on January 1st, 2009 the DOE released their final requirement and established the ENERGY STAR® program for Residential water heaters.
ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. Their goal for developing this program is to assist the residential water heater manufacturers in promoting high efficiency products that save money, use less energy, and deliver the same or better performance as comparable products.
