the question is whether you still need a large, powerful heating system in a modern, well-insulated single-family house with a heat recovery ventilation system. That's why my current favorite would almost be the air heat pump?
This is determined by a heat load calculation, which shows how big the heat generator needs to be. For me, the air heat pump would not be an option because the calculated heat load does not include the energy demand for hot water. That means you won't be able to heat the house including hot water solely from waste heat = electric heating element. This can work in passive houses if there are correspondingly low heat losses and solar gains can take effect.
The advantage would of course be saving the surface heating, the disadvantage the reheating via warmed air. I would find that uncomfortable; a surface heating system is more pleasant than a blower, to put it bluntly.
But in principle, yes, you can also use a controlled ventilation system with a heating coil and heat water via a dedicated heat pump, for example. That might be attractive in terms of investment. Or directly an air conditioning system that can also heat. That's how you see it in modern holiday homes, for example in Denmark, where previously only electric radiators were installed.
