Anybody install Fujitsu mini split heatpump and used the minimum heat setting of 50 degrees F?
Any other mini splits with this option?

How should the concrete floor in a pole barn be insulated for radiant floor heating? Does just the slab need to be insulated on the sides and underneath w/2"board and vapor barrier?
