Geothermal HVAC Systems deliver space conditioning — home heating, cooling, as well as humidity control. They can also supply water heating — either to supplement or even replace traditional hot water heaters. Geothermal Heating and Cooling Systems perform by transferring heat, instead of converting chemical energy to heat like in a furnace. Every Geothermal Heating and Cooling Systems has 3 main subsystems or parts: a geothermal heat pump to move heat between your building and the fluid in the earth connection, an earth connection for moving heat between its fluid and the earth, and a distribution subsystem for delivering heat or cooling to the building. Each system could also have a desuperheater to complement the building’s hot water heater, or a full-demand water heater to fulfill all of the building’s hot water requirements.
