Maybe I need new clubs
Roz,
Appreciate the kind words.
4 years ago, projects were running about $11.50 per SF.
That includes:
1.5” and 1/2" oxygen barrier PEX and fittings
In-ground manifold boxes
Supply and return manifolds
R-10 under-slab insulation
Propylene glycol for -20 freeze protection
Slab temperature sensors and controls
Plan design, large format prints, coordinating, scheduling, hand wringing, head scratching, sleepless nights, and installation labor…and general hair-on-fire controlling.
Concrete work is outside our scope of work.
Regarding the value of the under-slab insulation:
These IR photos show the same day difference at 0 degrees outside air temperature.
Both locations are equipped with Modcon boilers.
With insulation at 50% fire rate Without at 96% fire rate
