Geothermal Heating
During the heating cycle, a geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.
Geothermal Cooling
In the cooling mode, the heating process is reversed - creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.

A geothermal system involves a series of pipes installed underground. The pipes have a heat-absorbing/transfer fluid running through the system constantly.

In the summer, the geothermal system removes the heat from the conditioned structure and pushes it through an exchanger then downward into the pipes to be cooled by the Earth's geology.

In the winter, the process is reversed: the heat from the ground is extracted and pushed upward by the pipes, passed through the exchanger and then to circulate in the house via Water to Refrigerant equipment, Water to Water or VRV technologies.
