GeoThermal Has Begun!




Installation of our geothermal exchange system began late last week. Geothermal exchange systems use the Earth's constant temperature to heat and cool buildings. These heat pumps transfer heat from the ground into the buildings in winter and reverse the process in the summer.
A geothermal exchange system does not look like a traditional furnace or air conditioner. For one thing, most of the equipment is underground. A liquid-usually a mixture of water ad antifreeze-circulates through a long loop of plastic pipe buried in the ground. This liquid absorbs heat and carries it either into or out of the building.
One advantage of a geothermal exchange system is that is does not have to manufacture heat. The heat is free, renewable, and readily available in the ground. The only energy this system needs is the electricity to pump the liquid through the pipes and deliver the conditioned air to the building. The pumps are two units located inside the building.
These pictures show the digging process for laying the underground piping, there will be many many holes dug to heat and cool this massive project!
