    Christa,
    I did put Radiantec 7/8" tubing in the floor. I have actually used 
it, but rarely.
    Someday I'm gonna tighten-up my weather striping and maybe work out a
    way of covering the glass ( 34"x76"  patio door replacement glass) 
at night.
    This reminds me of another consideration: when I do fire-up the 
floor heat,
    the 6" slab soaks up heat for at least an hour before you can sense 
anything.
    Of course, it's that mass, along with 10" concrete north wall and 10"
    Spancrete ceiling that absorb and retain daytime gain.
