Geothermal Quote question
I am building a new home this Spring and I plan on having ground sourced geothermal. I received a quote from one contractor in my area. His plan is to do a 6 ton horizontal slinky loop field with a 4 ton heatpump. He claims that an oversized slinky loop field performs the best, however I’ve heard bad things about the slinky loops, and slinky is the only kind of loop they do.
It doesn’t seem efficient or cost effective to overbuild the field since that is a major cost. Does anyone have experience with this?
I’m also getting another quote for a straight line horizontal loop and vertical closed loop. I’m worried about the vertical since there is a lot of shale in my area and I’m not sure how deep the wells could go.
