For the past two days the site has been humming with heavy equipment. Three trucks and two trailers arrived with tools, a couple thousand feet of pipe, hoses and a generator. It’s messy, noisy work but it’s going surprisingly fast. In case you are a novice like me and don’t know much about geothermal, here is the short description of our project. The geothermal heating and cooling system will circulate water to the earth using a circulating pump, moving the water through the 5 vertical wells that are being drilled at a depth of 300 feet each. The earth, in this area, will maintain temperatures from 55-60 degrees F. The water that is circulated will extract heat (heating) from the earth in the winter and reject heat (cooling) to the earth in the summer. The constant ground temperatures help the system to be extremely efficient. Below are some photos to give you an idea of what this type of drilling looks like.
