Yeah, this is what I was referring to. The heat pumps available in the US only seem to work down to freezing (0C). After that, they just turn on resistive heating, which is very inefficient.
As far as ground sourced those are significantly more expensive. The cost/benefit is not there unless the only factor in your purchase is climate change.
