Floor is PEX tubing in 1 1/2 inch concrete slab on top of OSB. Ceiling/floor joists are engineered wood "I" beams, 16 inches on center. A labrynth of tubing, wires, PVC pipes and air ducting resides in the ceiling. Dimensions: 46 X 25 ft. (20 bays 46 feet long). Final layer will be sheetrock. Space below is entry level living space on radiant heated slab.

Albert,

Since the upstairs is over another living space, it sounds like your desire is to drive as much of the heat from the upstairs radiant floor UP through the floor...
