Excellent application of heat pump technology as the delta T (temperature
difference) is very consistent, meaning the smallest pump working closer to
full time (nothing worse than an oversized unit running a small fraction of
time, as far as economics go)
These systems are obviously more expensive than typical air sink heat pumps,
but some states may offer tax rebates or other energy incentives to use
them. A few years ago, when there were federeal credits as well, a friend
installed one UNDER his existing house (they bored from side to side and
brought the pipes up in his basement with amazing accuracy).... But his has
variable speed drive on the compressor, so I would suspect RFI issues....
fortunately he lives 30 miles from my shack so I have never checked it out

What about heat pumps that use ground water which 5 feet deep and down runs
around 50-55F
