Geothermal Heat Pumps

Now offering up to $500 in rebates



Geothermal heat pumps move heat from one place to another. It operates much like a standard air source heat pump except it exchanges heat with the ground instead of the outside air, essentially then using the earths free abundant heat to heat your home, creating increased efficiencies.

Heat Transfer Methods

- Open loop systems utilize well or spring water to provide the heat/cold transfer for a geothermal heat pump.


- Closed loop systems such as a vertical bore hole, horizontal trench, or pond loop circulate a brine (water/antifreeze) mixture to transfer heat and cooling from the earth to the geothermal heat pump.

Heat Pump Options


- Water-to-air geothermal heat pumps can provide hot and cold air to keep your home comfortable during the winter and the summer.


- Water-to-water geothermal heat pumps can provide hot and cold water to heat and cool your home with air handling units. They can also provide the benefit of radiant heating in concrete such as a basement, garage, or snow melt.

Services Provided


- Heat Loss Survey-  plans or measurements taken on site that will determine the size of the heat pump needed.


- Loop Design- vertical, horizontal, or pond loop.


- Duct Layout- the co-op can install or work with your contractor to design a duct system that will provide optimum efficiency & comfort.


Accessories- home air filtration, humidification, de-humidification, air exchangers, digital programmable thermostats.


System Installation- we staff our own installers.


The initial cost of a geothermal heating and cooling system is higher than the cost of a high efficiency gas or oil furnace; however, if a high efficiency air conditioner is installed with a high efficiency furnace there is usually very little difference other than the loop field.

For an average new home, (2000 square feet) the complete turn key installation of a geothermal water to air heat pump ranges from $18,000 to $21,000 not including drilling.
