> What matters is the SCOP for the system as a whole.
That's exactly what my numbers are.
They are the efficiencies for moving the heat-energy from the outside air into the inside air, assuming constant 20 degrees celcius indoor temperature and a specifically weighted outdoor temperature (there are multiple types of SCOPs, depending on the climate-zone and I was refering to the moderate one as it is present in most of middle Europe).
Whether you transfer the heat from the outside air (or some other medium) into the indoor air or into the indoor water does not matter - except that for the latter, you will need to consider that the water has to still transfer the heat to the indoor air, so you need to know how hot the water will have to be to calculate the SCOP correctly for your house.
> In a traditional Victorian house with a fireplace in every room, radiant heat will provide far greater efficiency than a forced air system, in which all of that warm air will literally go straight up the chimney.
What kind of "efficiency" are you even talking about? Can you please provide a definition and some example calculation? Otherwise it's meaningless to discuss.
No.
