The one thing that is missing from this article is that heat pumps can only create a certain temperature difference (while remaining efficient). In Europe, most houses are heated by pumping hot water through radiators (as opposed to blowing hot air around). Heatpumps can typically only heat that water up to 30 to 40 degrees Celsius while remaining efficient, which is not enough to heat the old, badly insulated houses in Europe. They need to renovate houses first, insulate them and replace the radiators.
- ZeroGravitas 3y agoFor Condensing boilers, the temperature of the water coming back from the radiators needs to be 45C in order to hit the advertised efficiency and eponymous "condensing", this is why their real measured efficiency is more like 75-85% than 96+% Same fix, larger, double vaned radiators and better insulation which is why some people are pleasantly surprised they don't need to switch radiators when moving from a modern condensing boiler setup.
