Geothermal – Solar Energy Stored in the Ground

By tapping into the solar energy stored in the ground, geothermal heat pumps provide heat and air conditioning for your home. 

Geothermal heat pumps take advantage of the solar energy just below the surface of the ground. 40 – 60% of the Sun’s energy is directly absorbed into the ground, making the earth a giant solar panel. Geothermal heat pumps use the Earth as a heat source or heat sink by transferring energy between the ground and your home through a series of buried, high-density, poly-ethylene pipes. The pipes are filled with a water solution and sealed using heat-fusion to weld pipe to pipe. These pipes are called an earth loop.

In the heating mode, the heat pump extracts heat from the water solution, concentrates that energy and distributes it into the home. The solution, having given up its heat in the heat pump, now circulates back through the earth loop at a colder temperature and solar energy naturally flows from the ground into the water solution, warming the water solution back up before its next trip through the heat pump.
In the cooling mode, it cools your home by extracting both heat energy and humidity from inside the home, the heat pump then concentrates that energy and puts it into the earth loop, now the water solution is warmer than the surrounding ground and heat naturally flows from the water solution into the earth. The system has no carbon dioxide emissions or any other negative effects on the environment.
