A geothermal heat pump system is a refrigeration device that utilizes a ground loop and the earth's energy to heat and/or cool a structure. The refrigeration cycle can leverage and multiply input energy into additional BTU's. Connected to the earth with its relatively stable temperatures, performance can be as much as 4 or 5 times the input. This can lead to substantial savings on the cost of heating and cooling a building. The closed loop (or geo-exchange) is a buried series of pipes that circulates a fluid to transfer the energy between the heat pump and the earth outside of the building. G.O. Loop installs these in-ground loops, vertical, horizontal, or in ponds and fills them with the fluid needed to transfer the heat.
