The easiest way to do this, at least that I can think of , would be to cover the existing concrete with some 1/4" luan. it won't be as good as foam for insulating, but should stop the majority of downward heat migration. Lay out your tubing and the either cover it with fiber cement(doesn't crack)or furring strips on either side of the PEX and cover with 1/2" or 3/4" plywood. The furring strips should be close enough to each other to prevent flexing of the covering plywood, similar to what Doax pictured above. The additional height(thickness) would be kept to a minimum. Possibly consider 3/8" soft copper tubing instead of PEX for maximum heat transfer. It shouldn't cost any more when the cost aluminum transfer plates are factored in.

From the research I have done, Roth Panel is always among the top of the list when high-efficiency radiant floor geeks list their favorite systems. Covering RP with some kind of floating floor system (like bamboo, etc) seems to be mentioned favorable most often. But covering with 1/4" Hardibacker and then linoleum would be even more efficient... if you can go with the look. * * * Quote:

But aluminum heat plates are used because aluminum is a good thermal conductor, and the area of the aluminum plates is very large. 3/8" copper tubing is a great conductor, but it wouldn't have a very large area... so not so good. -AC
