Geothermal heating and cooling systems are time proven, rock solid works of art that provide great benefits from every conceivable angle in a building’s HVAC system. Many ask, what might be done to reduce first cost?
In North America, state or provincial regulations work to ensure that wells are properly drilled and do not pose a threat to valued groundwater aquifers. An important aspect of completing a well is to grout the annular space between the drilled borehole and the casing.
Recently, I was driving to an appointment and I passed a drill rig that appeared to be drilling a new well very near the road I was driving on. Both the driller and his helper were working bare headed.
