Consumers would save a total of $11.4 billion annually on water and energy bills under the Department of Energy’s (DOE) newly proposed energy efficiency standards for water heaters.
The standards, which are mandated by Congress, would require replacing common-sized traditional electric resistance storage water heaters with heat pump technology and gas-fired instantaneous water heaters to achieve efficiency gains through condensing technology. The standards are expected to reduce 501 million metric tons of carbon dioxide emissions cumulatively over 30 years, the agency said.
