Geothermal - well question
Hi! Totally new to this whole geothermal heat pump way of heating/cooling, but sounds fantastic. I was wondering - we have an old unused well from the 1800's on our 3.5 acre lot - can they use this well (and maybe minimal drilling) to install one of the loops? Water table is high - just a couple feet and you hit water (we're just south of Lake Erie a few miles).
Also, we have no duct work in this old house (early 1900's) - its 2 story, about 2,00 sq ft. Is it possible to install tiny tubes to carry heat/cool to the second floor and put them in the walls, or do we need to add duct work? (i love our old plaster walls, and would love to avoid having to disrupt too much of the architecture).
Thanks for any advice / input!
