Geothermal FAQs
The use of an existing well is a possibility but generally not conducive to a proper closed loop installation. The depth of the well and size of casing will be a consideration. Vertical loops are generally drilled by way of a 3' casing to a depth determined by the loop requirement. The well is then filled with a slurry to optimize heat transfer. The number of wells required is calculated as per the heating / cooling load of the home
Loops are generally laid into trenches that are 6ft wide by 6ft deep and are approx 300ft in length. The amount of loop depends on the heating / cooling load requirements for the home in question.
