Commercial Benefits
In addition to the general benefits of a geothermal system, there are other
advantages for the commercial user to install a geothermal heat pump system.
Efficiency
In the heating mode the geothermal heat pump system extracts two-thirds or more of its energy from the earth and moves it to the heat pump unit. Only
one-third of the energy needed is  purchased power. This is used to run the compressor, circulating pumps and fan. In the
cooling mode, the unwanted heat is transferred back into the earth for reuse in heating.
No Ground Level Outdoor Equipment
All of the equipment needed can be installed in one or more mechanical rooms,
above dropped ceilings, or on the roof. There are no visible outdoor units to
suffer from deterioration due to weather or vandalism, and no outdoor noise.
The remaining equipment consists of an array of piping buried beneath the ground. These pipes can be
installed in a vertical well system, horizontally buried under the surface, or
installed in a pond. In some cases, well or pond water can be used directly
without buried pipe.
Environmental
Geothermal heat pump systems produce no on-site pollutants, improve indoor air quality, and reduce the amount of pollutants at the
generating station when compared to other forms of electric heat. They also result
in lower carbon dioxide emissions which reduces the threat of global warming.
Service Hot Water
In cooling mode, the unwanted heat can be used to preheat your hot water at a very low
operating cost. In winter, surplus heat can be used in the same way.
Warmer Air Distributed During Heating
No more seemingly cold drafts from the air outlets often encountered with
conventional heat pumps.
No Supplemental Heat
Most geothermal systems can operate year-round without supplemental direct
heat.
Little or No Out-of-Pocket Incremental Cost
Any added initial cost can often be included in the financing, and the
operating cost savings used to amortize the added investment, if any.
