Re: radiant heat
The question asked was:
"What about radiant heat for use in homes with cathedral ceilings?"

In a home with radiant floor heating, if you are comfortable lying in bed, should you move to the floor, you will be overheated.
With any other form of heat, you will be colder if you move to the floor.
In a home with a cathedral ceiling (like mine) it doesn't matter whether it's warmer at the ceiling or not. I "live" in the home environment which is at six feet or less from the floor.
In my case, trying to move the stagnant, slightly warmer, moister, air at the ceiling probably would make things worse.
I have no insulation at the roof. Any heat rising there has probably already re-radiated (lost) through the roof to outside. Even if the cathedral ceiling air was measurably warmer, the very movement of air -- even slightly warmer air -- across skin tends to cool the individual.
(There would be no gain -- perhaps a loss -- in trying to move cathedral ceiling air downwards).
Radiant heat is very different from convection heat. Any comparison is apples-to-oranges.
Electrically-supplied floor radiant heat, as pictured elsewhere in this thread, may be very expensive.
The radiant heat I formerly lived in was oil-fired -- and bulletproof -- for 40 years.
