I’m very interested in the radiant floor. Not very common on the west coast but I think it has great potential, especially with high ceiling homes or just taking the chill out of a workshop.
Since the tubing is embedded in the concrete they create ‘zones’ with specific runs. I wonder if they build in any redundancy using side by side backup tubes? Also, do you need a thicker slab due to the tubing potentially creating weak points or thinner slab cross section.
Do your architect create the working plans? I’m looking for a draftsman for such.
