Drilling began last week for the geothermal wells. These photos show the test drills that were made to determine the substrata in the area we will put our well field. There is plenty of rock in that area... and in this case, that is a good thing.
These are not "water" wells. In fact, each well is encased and dry. The well will be a shaft that holds a double loop of water filled pipe which will be heated by the earth and circulated throughout our hvac system.
Watch for an in depth posting on this process soon!
