What is a Geothermal Heat transfer pump (GHP)?
A geothermal heat pump is an extremely efficient machine used for heating and cooling which extracts heat from one place and moves it to another place. It works like a refrigerator which has a type of heat pump in it that extracts heat from the food compartment or freezer thus making the temperature inside drop and keeping your food cold. The extracted heat is then moved to the coil (the one that gets warm) in back of the refrigerator where the heat radiates into the air. A Geothermal system is like that except on a bigger scale. In the winter a GHP extracts heat from the earth and moves it into your home or building. In the summer a GHP can extract heat from your home or building and moves it into the earth and stores it there. When winter rolls around again, the GHP will extract that stored summer heat and moves it back into the house.
