This would only work for heating though and would have a significant latency (you have lots of thermal inertia in the system). Why not go with standard reversible A/C units which not only would also provide cooling capability but process the air locally so you don't have to wait for pipes/radiators to warm up before actually getting heat?
- ricardobayes 4y agoMy research lead me to exactly the same conclusion. Heat pumps cost the earth if you call them heat pumps, but once you call them an inverter split A/C they magically cost an order of magnitude less (even though it's the exact same tech).
- ZeroGravitas 4y agoYou do get slightly different tech when aimed at air-to-air and air-to-water needs, and different target temps and there's newer generations of the same tech that rivals ground source heat pumps. So its not just a rip off, though there's probably a fair bit of that too as demand has risen recently.
