By moving , rather than creating heat, geothermal heat pumps are an extremely efficient home heating and cooling option. This topic discusses energy efficiency of open geothermal heat pumps geothermal heat pump operation , and advantages and disadvantages of geothermal heat pumps .
Geothermal heat pumps use less energy than conventional systems.
The table below describes how they move and condition the air in the heating and cooling seasons. Cooling season Heat is moved from indoors, and cooled by the earth or water as it circulates through the loop. The advantages of geothermal heat pumps far outweigh the disadvantages. The table below describes the advantages and disadvantages of geothermal heat pumps over other heating systems. No visible outdoor unit Quiet operation Requires favorable source of ground water for a water loop system, or soil conditions for an earth loop system.
