Problem with that is electricity is expensive in Europe. Of course as you know Europe varies a lot between Portugal and Romania. While the first has a balmy 10C in winter daily low, colder areas can easily have -10C, -15C at night. That's the minimum operating range of a heat pump.
That's a 30C difference to work through. That's why they have cheap (Russian) gas, it has the biggest energy density (and nuclear).
Ground-source heat pumps would work better in continental Europe but they are expensive to install (I have only seen them in new build villas).
- samatman 5y agoPutting the gas into electric generators and using that electricity to heat is more economical than burning it in a furnace for heat, heat pumps are just that much better. I agree that the national programme must be more detailed than just declaiming "heat pumps!" and calling it even. I gestured vaguely at the existence of parts of Europe where cheap mini-splits might not be sufficient, let's just agree I'm talking about the places where they will be.
- ricardobayes 5y agoApologies if my comment made it seem I disagree with you. Air-source heat pumps can definitely be used in many countries here, in fact they are already popular in the UK, and gaining popularity in Spain, due to their efficiency.
