The radiant heat will dry the wood too much, the interior will be a 'hot box' in and of itself. Not a fair comparison. A traditional radiator is hot, often too hot for sustained touch, which means, 120-140 deg surface temp. Water temp in the radiator is much hotter, around 180 deg I think. Notice how baseboard hot water is protected from surroundings by a shroud. An infloor system should be running at surface temperatures that are only faintly warm to the touch, or even just under skin temp. What is skin temp?...Its not 98.6deg...its got to be lower. My system water temp is supplied at 110deg. This means, by the time the 110 deg water heats the floor, surface temp of the floor is not even necessarily warm to the touch. Put another way the floors are not radiating cold as floors, walls and windowes usually do, but not necessarily radiating hot either. Surface temp is often just the slightest bit cool to the touch. UNless of course the house is drafty. Then the system like any other system gets cranked, but still it never functions like or at the temperatures a conductive radiator functions at...apples to oranges...
