What are Geothermal Heat Pumps
Geothermal heat pumps use the natural insulating properties of the earth from just a few feet underground to as much as several hundred feet deep, offering a unique and highly efficient renewable energy technology for heating and cooling.
Most work by circulating water in a closed system through a “loop field” installed horizontally or vertically in the ground adjacent to or even beneath a building. Heat is taken from the building and transferred to the ground in the summer.
The system is reversible, and heat is taken from the ground and used in the building in the winter. The system only moves heat, which is much more efficient than using a fuel or electricity to create heat.
Geothermal heat pumps can support space heating and cooling needs in almost any part of the country.
Main types of Geothermal geothermal energy systems include geothermal heat pumps, power plants that produce electricity, and direct use in heating systems.
