The Energy Star site says:
Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. By choosing ENERGY STAR certified heating and cooling equipment and taking steps to optimize its performance, you can enhance the comfort of your home while saving energy. Saving energy helps you save money on utility bills and protect our climate by helping prevent harmful carbon pollution and reducing other greenhouse gases.
Geothermal heat pumps (GHPs) are among the most efficient and comfortable heating and cooling technologies currently available, because they use the earth’s natural heat to provide heating, cooling, and often, water heating.
ENERGY STAR qualified geothermal heat pumps:
- are over 45 percent more energy efficient than standard options.
- now include water-to-water GHPs. Water-to-water GHPs provide space conditioning and/or domestic water heating using indoor refrigerant-to-water heat exchangers.
