Geothermal Ground Loop Design Information
I'm looking at installing a geothermal vertical loop system on my acreage in the Buffalo/Western NY area. My installer has been very responsive in answering questions verbally or on email. However, I really don't feel like I have a good understanding of the ground loop design. As it is not something I can change on a whim...that concerns me.
My property is on a former quarry. The installer is local and proposed a horizontal loop and we signed on that. We were digging on our property for another project and we encountered bedrock within 2-4 feet. Subsequently, we pushed the geothermal contractor for testing, and they confirmed all their proposed locations are too shallow for horizontal
Now, I'm concerned. As I had to push for testing, the installer did not propose it. Tho, fair enough, it was mentioned in the contract. Technically, up to me to push for it.
Now, we are looking at vertical loops. However, I'm not getting many details beyond the depth and we can put the loops "any where you want." This last is what gives me pause. It just seems a bit unscientific and leaves me feeling uninformed.
Has anyone gotten a design or loop report prior to purchase?

I'm particularly interested in hearing about installation testing (see below from a mockup). And of course, I'm concerned I am being to anal about wanting this. This contractor has a great local rep.
