Schools Benefits

In addition to the general benefits of a geothermal system, there are other advantages for schools 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 pump and fan.

In the cooling mode, the unwanted heat is transferred to the earth for reuse in winter.

No Ground-Level Outdoor Equipment
There is no visible outdoor units to suffer from deterioration due to weather or vandalism. All of the equipment needed can be installed in one or more small mechanical rooms. The heat pump units can be installed as console units on outer walls, or above dropped ceilings. Since there is generally no rooftop equipment, there are no expensive and troublesome roof penetrations.

The rest of the equipment consists of an array of piping buried beneath the ground, often under athletic fields or parking lots. These pipes can be installed in a vertical well system, horizontally buried under the surface or even installed in a pond. In some cases, well- or pond-water can be used directly without buried pipes.

Environmental
Geothermal heat pump systems produce no on-site pollutants. They actually 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
When cooling, the unwanted heat can be used to preheat needed hot water at a very low operating cost. When the system is heating, surplus heat can be used in the same way.

No Cooling Tower or Boiler is Usually Required
The only non-heat pump heating equipment needed is for final service water heating. This helps to further lower maintenance costs.

Little or No Out-of-Pocket Incremental Cost
Any added first cost can often be included in the project financing, and the operating cost savings used to amortize the added investment, if any.
