The geothermal heat pump system consists of:
       a water-source heat pump
       a closed loop ground heat exchanger made of high density
            polyethylene pipe (guaranteed 25 years or more by many
            manufacturers)
       a low wattage circulating pump(s)

In the heating mode, the closed-loop heat exchanger absorbs heat from the earth (typically 50 F to 70 F) and transfers the heat to the refrigerant via the water-to-refrigerant heat exchanger. The compressor concentrates the heat absorbed by the refrigerant before it flows to a coil in the supply air stream. The coil heats the air moving across it and heats the house. An antifreeze solution may be added to the ground-loop heat exchanger to prevent system freeze-up when heat pump leaving water temperatures drop below the freezing point of water, 32 F.

In the cooling mode, the heat pump extracts heat and moisture from the air and rejects the heat into the refrigerant. The heat is transferred to the fluid in the ground loop system via the heat exchanger. The ground then absorbs the heat from the ground loop.

As a benefit of the system, unwanted heat in the cooling mode can be captured by a desuperheater and used to produce virtually free hot water by reducing the hot water heater's run time. The desuperheater can also be used to greatly reduce the cost of producing hot water in the heating mode by reducing the hot water heater's run time.

Due to constant moderate earth temperatures, the system can be twice as efficient as an air-to-air heat pump, and more than three times that of high efficiency gas systems. Moderate earth temperatures translate into the highest comfort levels in cooling from increased dehumidification and higher supply air temperatures in heating.

Another benefit is that the system requires no defrost cycle and little to no supplemental heat.

The geothermal unit is located entirely within the home, much like a refrigerator. By avoiding outside weather extremes, the unit's life span is expanded. Field refrigerant connections, and an outdoor air conditioning unit are no longer needed.

The unit is compact enough to be installed just about anywhere. It can be placed in an attic, basement, or tucked away in a closet.
