How does a geothermal pump system work ?
Geothermal pump systems exchange thermal energy between a
building and the ground. When the building needs heating, the system
extracts heat energy from the ground, and pumps it into the building
where it is boosted by the heat pump to a comfortably warm
temperature. Conversely, when the building needs cooling, the heat
from the building is collected by the heat pumps and sent into the
ground, much as a refrigerator's compressor transfers heat from
inside the refrigerator to the outside. This exchange of thermal
energy makes the system efficient. Rather than creating heat by
burning a fuel on site, or chilled water by rejecting heat to the
hot summer air, the geothermal heat pump system moves thermal energy
between the ground and the building using heat pump technology.
