Geothermal Systems use the earth as a heat source during the winter and a cooling source in the summer. Ground and water temperatures just 6 feet below the earth's surface stay relatively constant throughout the entire year. This allows the geothermal system to provide extremely efficient heating or cooling all year long in any climate. A geothermal system absorbs or rejects heat from the earth and has no impact on the environment.
In order for a geothermal system to operate, normally a 6" hole is drilled to the correct depth. Geothermal wells are typically anywhere from 150' to 400' feet deep, with some wells going to 600' for larger commercial projects. Under normal circumstances your residential geothermal well will not be less than 150' deep.
Normally, a 200' well can provide about 500 sq ft of Heating or Cooling area. If your current area is roughly 1500 sq ft, it's safe to assume that you would require 2 separate wells drilled to roughly 300'. Geothermal pricing is slightly higher than standard well drilling, but it's actually cheaper in the long run. The more wells you have drilled, the less per well cost you incur.
Since 1978, Kouba Well Drilling Company has provided Wisconsin with Geothermal well drilling services.
