Geothermal Heat Pump Working Principle And Application

The ground source heat pump (GSHP) uses buried pipes to extract heat from the ground, and then it is used to heat radiators, underfloor or heating systems, and hot water at home. The heat from the ground is absorbed into the liquid and then enters the heat pump through the heat exchanger

Ground source heat pump and geothermal heat pump belong to water source heat pump or water to water heat pump. They use water to enter the earth and directly or indirectly absorb the energy stored in the earth. Whether in spring or summer, the temperature under the earth is relatively constant. Using this energy of the earth can better and more effectively provide heating, cooling and hot water for homes and commercial buildings.

Geothermal heat pump basically works like other heat pumps. A heat pump is a machine that uses a refrigeration cycle (as used in your refrigerator) to transfer heat - they heat the hot side and cool the cold side. In winter you want the hot side of the house, the cold side of the outdoors, and in summer the opposite.

The advantage of GSHP is that it's much easier to transfer heat to a cool earth when cooling than to transfer heat from your home to the hot summer air, so it doesn't have to work so hard to cool your home. There is a bottom line to this efficiency - your monthly electricity bill will be greatly reduced!! The same is true for heating seasons: it is much easier to absorb heat from warm soil than from cold outdoor air.


The geothermal system provides great comfort. The precise distribution of comfortable air throughout the year eliminates hot and cold spots. In winter, you will enjoy the warm air without the hot air associated with the stove. Compared with air source heat pump, the air entering your home through geothermal heat pump is much warmer, and there are no more outdoor fans running day and night.

The geothermal heat pump is a central heating and/or cooling system, used to pump heat to or from the ground. It uses the earth as a heat source (in winter) or a radiator (in summer). This design uses the medium temperature of the ground to improve efficiency and reduce the operating cost of heating and cooling system, and may combine with solar heating to form a more efficient earth solar system.

In application, geothermal heat pump has outstanding performance in providing hot water, space heating (providing hot water for underfloor heating or radiator, or providing heating air) and refrigeration. So in a variety of building types, including office buildings, apartment buildings, hotels, apartments, schools and so on. As well as some industrial or agricultural areas with demand for hot water and cold water, GSHP can provide the most stable and best performance hot water and cold water.

To Choose good ground source heat pump, and FANTSTIC ground source heat pump is recommended.
