Ratio of radiant to convective heat transfer
I'm currently trying to decide on a radiator vs blown air central heating system and it seems difficult to get real data. I hear a lot of emotive phrases like "radiators are a much nicer heat" and "it warms the things in your room, not just the air"... and usually the person says the word "science" once to back up their position.
But what I want to know is:
What percentage of the heat emitted by radiators is due to IR radiation vs convection?
I'm talking about heating an insulated home with modern water heated panel radiators vs modern blown air heating.
I had one radiator installer suggest theirs were only 10% radiation, and obviously much less if hidden behind a sofa. If that's true then any argument about "directly heating objects" is clearly just marketing babble which architects seem to have latched onto.
Any recommendations or links would be greatly appreciated.
