thats true in spaes for air source heat pumps... if yoou dig deep for
ground water though, water source works in cold weather..but it has
issues, closed loop allows the addition of anti freeze... there are
contamination issues with that though...I use propelene glycol, non
toxic... ethelene glycol is poisonoous however, if someone s that
later and it leaks to the ground water you could ruin a good sized
aquafer... damages could be into the millions.
