Re: The big problem however...
We looked at ground-source heat pump install in a large complete refit (to new build standards) and this cost was about right. What I hadn't considered, and what ruled it out in the end, was the amount of electrity required to run the pumps moving the coolant. We needed an entire phase just for that, apparently. With a solar-farm out back it might have been viable.
