The U.S. Department of Energy (DOE) today proposed new energy-conservation standards for commercial water heating equipment, including gas storage, instantaneous water heaters, and gas hot water supply boilers. The proposed standards would require commercial water heaters to incorporate condensing technology, which significantly reduces energy consumption by extracting additional heat from the combustion process. Energy efficiency is a key component of President Biden’s plan to reduce climate pollution while delivering savings. 

“Water heating accounts for a considerable share of energy costs and domestic carbon emissions,” said Kelly Speakes-Backman, Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy. “Modernizing commercial water heater technology will slash energy costs for schools, hospitals, and small businesses while removing carbon and methane from our atmosphere.”
