Résumé

Many ground source heat pump (GSHP) systems, also known as geothermal heat pumps (GHPs), have been successfully installed and operated for many years throughout the United States. However, other installations have experienced poor reliability, high energy costs, and undesirable ground loop temperatures. Some have had significant equipment replacements, have added supplemental heating, or installed fluid coolers. A few GSHPs have been abandoned. It has been suggested that a reason for abandonment may be the overheating or freezing of ground formations or groundwater due to imbalances in the amount of heat stored and removed.
