Radiant floor heating.?

radiant heating

Can Radiant Floor Heating be installed in the concrete pour, then after concrete has sufficiently cured (28 days) can a resinous coating, such as a epoxy/polyurethane floor coating be installed on a floor that will later be radiant heated. My concern is that these coatings are very moisture intolerant. Does radiant floor products, create any moisture in the slab that could rise to the surface. Does changes in temps affect the moisture levels in concrete. Electric radiant floor products seem to be best.
Pipes filled with hot water to me is a concern. Do the pipes "sweat" causing condensation or are they wrapped. I am currently on a large project and these questions are coming up in the design forum.
