I’ve Heard about Geothermal Heat Pumps – What Exactly Are They?

Geothermal heat pumps are used for home heating and cooling. They are a relatively new phenomenon and are now being installed by an increasing number of American homeowners. Due to their impressive energy-efficiency, these heat pumps are definitely worth considering. To help you understand the ins and outs, here is some basic information.

  • Geothermal heat pumps utilize heat below the ground to cool or heat a liquid coolant or water. The temperature under the ground remains a constant 55 degrees all year round.
  • Most systems also provide hot water, so you don’t need a separate water heater.
  • Underground piping is filled with water or coolant to deliver heat from inside your home and release it into the ground during summer. During winter, the piping extracts heat from the ground and delivers it to your home. See this illustration of how it works:

  • There are 3 main parts of a geothermal system:
  1. The heat pump
  2. The earth connection
  3. A distribution system which delivers cooling and heating to the building
  • The incredible efficiency of geothermal heat pumps is due to the fact that these systems only have to cool or heat the fluid or water in the pipes by 15 – 20 degrees. Compare this to a conventional HVAC system which must heat or cool air by as much as 40 to 50 degrees in some regions.
  • The Environmental Protection Agency estimates that a geothermal heat pump can save the average household 20 to 50 percent on cooling costs, and 30 to 70 percent on heating costs.
