This week I went to an event where they had this amazing machine that demonstrated the workings of a heat pump: taking a unit of heat from the right side and transferring it to the left side, the beers are cooled and the (vegan) sausages are warmed. I think it's brilliant and should be used to overcome any doubts or resistance to heat pumps, especially in Germany. Maybe they should be mandatory in every beer hall?
