Geothermal Heat Pumps

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 certified 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.

Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the U.S. 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.

Current Specification Effective Date: January 1, 2012

On average, ENERGY STAR certified products covered under this new specification will be over 45% more energy efficient than standard options. ENERGY STAR certified models are more efficient than models that simply meet the federal minimum standard for energy efficiency.

Remember, even though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills.

You can get better heating and cooling performance at home with ENERGY STAR home sealing (insulation and air sealing) and duct sealing.

Consider regular maintenance of your heating and cooling system to prevent future problems and unwanted costs.
