I was thinking of pulling the pump back up and putting a copper coil in the 10' at the bottom with a plastic pipe feed and return to my heat pump. Then put the pump back down the well. We don't use a lot of water from the well however it seems to me this would work even better than a 180 ft hole filled with grout, as every time I use water, cold water will come into the shaft. Oh and I live in central TN.

I think the issue will be how fast the water comes back into the well shaft.

If you really know how fast the water comes into the well shaft on a sustained basis, you are on your way to knowing how much heating or cooling you can expect from your well.
