One question we hear about barndominiums:
“Does radiant floor heat actually work with really tall ceilings?”
Tall spaces are actually one of the places radiant heat makes a lot of sense.
Here's why.
Forced air heats the air.
Hot air rises.
With a soaring ceiling, some of the heat you paid for ends up where nobody is sitting.
Radiant heat works differently.
It warms the slab and the occupied space from the floor up.
But good performance depends on getting the details right:
1. Proper insulation beneath the slab.
2. Perimeter insulation.
3. Correct loop spacing.
4. Extra consideration around large windows and exterior walls.
5. Understanding that concrete responds slowly, so the system works best when operated steadily.
The ceiling height isn't the problem.
The design of the system matters.
P.S. Would you choose radiant floors or traditional forced-air heat in your barndominium?
