On February 14, 2025, DOE announced that it is postponing energy efficiency standards for seven categories of appliances and equipment. The decision affects central air conditioners, clothes washers and dryers, general service lamps, walk-in coolers and freezers, gas instantaneous water heaters, commercial refrigeration equipment, and air compressors. The announcement also indicated that DOE is creating a new energy efficiency category into which natural gas burning tankless water heaters will be placed, which causes those water heaters to be exempted from existing water heater efficiency standards.
