hi all-

don't know much about the effect of radiant heat on composites but did install 
a long radiant tube in my hangar/shop (50'x48'x16' sides, 26' high center) at 
a height which would keep the tube at an adequate distance away from aircraft 
per the heat tube manufacturers recs and the hangar (ground level) never got 
above 54 degrees F in the winter in west virginia even with ceiling 
fans-totally inadequate and unacceptable for a $2000 +installation system. 
ended up going with a forced air 300,000 btu system (bought from grainger) 
which works amazingly well.  check out whether the radiant heat system will be 
adequate for your needs before plunking down the money.

oh by the way, i'd be happy to sell the radiant heat tube if anyone's 
interested!

[I've spec'ed those heat tubes into several factories I've setup in areas 
where we needed to provide some warmth for the employees without concern for 
heating the space in general.... I call them "head warmers", and on a loading 
dock or adjacent area that's difficult to keep heated those things work fine 
at keeping the help from freezing, but not much more.  The radiant IR works 
directly on body parts just fine but doesn't pump enough energy into the floor 
and contents to get them to re-radiate enough heat to actually warm the 
surrounding space.  Not unless you setup a bank of them, and then it would be 
cheaper to operate a regular forced air furnace.  Your 300kbtu furnace will go 
much further at keeping not only people but your project actually warm enough 
to do some layups <G>.  Just my 2c.
