What Does Geothermal Heat Pump System Mean?

A geothermal heat pump (GHP) system is a heating and cooling system that transfers heat to or from the ground using a ground loop system. The geothermal closed-loop system has continuous looping pipes that are filled with anti-freeze to help temperature transfer. It can be installed vertically or horizontally depending on the available space in a property.

The system is connected to a well or a pond and directly pumps the water to the heat pump located at the building for heating or cooling. The water is disposed of by surface drainage to a low lying pond or river or by pumping it back to the water source.


Trenchlesspedia Explains Geothermal Heat Pump System

Geothermal energy refers to the heat energy available within the earth. Since heat is continuously generated inside the earth, the energy derived from this heat can be used to power home appliances, heat buildings and generate electricity. Heat is continuously generated below the earth's crust due to hot and molten magma. The heat derived from the sub-surface is carried to the earth's surface by water or steam which can be used to heat and cool buildings.

Geothermal loop system is a heating system with underground looping pipes that are filled with a liquid such as an anti-freeze that aids the transfer of ground temperature to the geothermal heat pump. There are two types of geothermal loop systems namely the open-loop system and closed-loop system. Geothermal heating systems are gaining popularity because they are environment-friendly and economical compared to other heating methods.

Trenchless techniques such as horizontal directional drilling can be used to help pass the pipe under the ground without breaking open the yard or the driveway. IGSHPA is the leading organization in setting out standards of design and practice of geothermal heat pump systems in the United States.
