not OP. My understanding is that situations like these really require installation of the (IMO, ugly) wall units ("mini-splits"). Current air-source heat pumps

Current air-source heat pumps can't produce hot water at temperatures necessary to drive radiators.
- skrause 4y agoIt depends on your radiators and insulation. As a rule of thumb modern air-to-water heat pumps have a good efficiency up to a water temperature of 55 C. That can be enough if you have radiators with a large enough surface and no terrible insulation.
- abakker 4y agoI think they can produce water at temps to support both radiators and radiant floor heat, but they can't produce the capacity/volume needed
- oceanplexian 4y agoThey don’t have to be ugly! You can get mini splits in a cassette format that just looks like an air vent. I’m not against ducted systems or anything (Most houses in the US have them). But the laws of physics pretty much guarantee that a mini split will always be more efficient. Air ducts are harder to insulate and not that good at moving heat energy compared to sending refrigerant right to where you need it.
