New Category Earns Energy Star
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.
