U.S. Department of Energy has finalized higher energy efficiency standards for residential water heaters, pool heaters and direct heating equipment such as gas fireplaces. The standards increase the stringency of the existing minimum conservation standards for these three types of residential heating products, which account for about 18 percent of energy use in homes across the country.
The standards will significantly reduce energy consumption by these products, including decreasing energy use in large electric storage water heaters by 47 percent and by more than 30 percent in large gas water heaters.
Standards for water heaters will go into effect in 2015, while the standards for pool heaters and direct heating equipment – including gas-fired wall, floor and hearth heaters – will apply to products manufactured in 2013 and beyond.
Since the election, DOE has issued or codified new efficiency standards for more than twenty different products:
- March 2009 – 14 consumer and commercial products with standards prescribed in the Energy Independence and Security Act of 2007 (EISA 2007), including dishwashers, general service incandescent lamps and residential clothes washers
- April 2009 – Microwaves, kitchen ranges and ovens
- July 2009 – General service fluorescent lamps and incandescent reflector lamps
- July 2009 – Commercial heating, air-conditioning and water-heating equipment
- August 2009 – Beverage vending machines
- December 2009 – Commercial clothes washers
