@magnatom @janrosenow 1) Great thread. Thank you. I would throw one very practical problem into the discussion though and it's design. I am lucky enough to be able to afford a heat pump but I've nowhere to put it. The way most of our houses are built doesn't allow for the unit to be installed. We simply do not have the space and there's another problem. The developer had done our (very small) garden in a way so any digging would damage drainage infrastucture.

@magnatom @janrosenow 2) Second issue for people is lack of a proper info campaign. Heat pumps run the water at a lower temp. That's the point. The best way to utilise that is by installing floor heating (and have a house designed for that). Most of our wooden frame houses would require a massive investment to do that. What the British government did was throw the term Hear Pump in the air and announce a grant knowing that we are simply not there.
