Thanks, Eric. That is exactly the kind of firsthand experience I was =
hoping to tap into here. Our emails crossed in the ether, so a couple =
of comments:
First and foremost, I am very jealous of your garage! 650 sq ft is the =
best I can do on our lot, at least if I want to keep my wife. =
Fortunately, some of the second floor will be garage storage and our =
house does currently have a one car garage under it, which will be =
retained.
The house has forced air heat, so tying the two systems together isn=E2=80=
=99t an option for us. I wish it was. My understanding is that there =
are now some very small, very efficient heaters available for radiant =
systems. I have just started researching those, so it would be great to =
know if anyone has any experience with those.
Your comment about the bubble wrap insulation under the slab is one of =
the important things I was looking to learn more about. My research to =
date has been very mixed about the relative merits of the bubble =
insulation vs. rigid foam. It is good to know you are happy with what =
you used. What did you do about permitter insulation on the slab? =
There seems to be two schools of thought on that, too. Some put rigid =
foam between the footers and the slab, so it is essentially a floating =
slab. Others put the insulation around the outside perimeter.
How accurate is the IR camera? Can you actually see the outline of the =
pipes? They are pretty pricey; do you know if the ones that attach to =
smart phones will also do the trick?
That=E2=80=99s all I can think of at the moment, but I really appreciate =
the advice.
