New Category Earns Energy Star

December 28, 2009

WASHINGTON - The U.S. Environmental Protection Agency (EPA) announced new requirements for residential geothermal heat pumps (GHPs), enabling water-to-water geothermal heat pumps to earn the Energy Star label for the first time. According to the EPA, the stringent specifications for this new category of geothermal heat pumps will help protect the environment and reduce energy costs because GHPs that meet the new standards will be up to 45 percent more efficient than conventional pumps.

EPA worked with industry stakeholders to revise the requirements in response to growing consumer demand for water-to-water geothermal heat pumps. Water-to-water geothermal heat pumps provide heating and cooling and/or water heating to a building using liquid rather than forced air. The new requirements for water-to-water equipment complements existing efficiency and performance requirements for water-to-air and direct geoexchange GHP models. Homeowners who install geothermal heat pumps with the Energy Star are eligible for a 30 percent federal tax credit.
