I was getting ballpark quotes ranging 15-20K for my house. Since in the city I would need to go vertical so about 5K of the quotes was for the bore, that portion might be lower with horizontal.
A geo-loop for a large tank might be an idea worth considering and is basically a DIY.
Solar panels are a good idea if your thinking water heating not electricity. Using panels to pre-heat water for radiant floor heating or hot water tanks makes sense.
