Can a geothermal system work just as well with multiple shallow wells vs fewer, deeper wells? We moved out of the greater Washington DC area last year looking forward to a quiet retirement in the northwestern area of Virginia. We had an unpleasant surprise with almost $4300 in propane cost more than $1340 in electrical for our 3,080 square foot, two-story home. We needed to make some changes. The long and short of it is, we have gotten bids from four geothermal installers. In reviewing the bids, most were drilling six to eight 200+ feet deep vertical wells. However, one installer proposed a geothermal system with sixteen 85-feet deep wells for a Climatemaster Digital series split 2 stage heat pumps models TES049 and Climatemaster Digital series split 2 stage heat pumps models TES049. He has said by not having to using the costly well drilling rigs and instead using a different type drill, he was able to lower the cost of his bid. At $38,000, his bid was about $5,000 cheaper than other companies for similar installations. He had good references and has installed geothermal systems for more than eight years. He is not accredited by IGSHPA but has passed a certification program from Waterfurnace on service and installation of geothermal systems, Climatemaster for their digital geothermal systems, ground loop design and installation, geothermal pipe fusion. He has a master HVAC license in VA as well as WV and hold a Class A Contractors License in the State of VA and a WV Contractors License, both of which are unlimited licenses. In VA that is the highest contractor’s license level. Again, can a geothermal system work just as well with multiple shallow wells vs fewer deeper wells?
