Yeah I get that, it was the comparison between electric direct and electric boiler feeding a wet system that I found interesting.
Your HP will pretty much be 1:1 in the middle of winter when you need it most, no?
At least 1:4 isn’t the minimum efficiency they run at, is it?
Fwiw to get either to feel like a really great solution I think you need solar panels to feed them and a really well put together house.

Maximum cop on electric heating will be a theoretical 1.00
With a HP you should be getting c. 4.00.
This means for every 1kw of electricity put into electric UFH or radiator you will get 1kw of heat.
With HP for every 1kw of electricity put into your HP you'll get c.4kw of heat energy.
