I am pouring concrete on a wood floor and placed ice and water over the wood floor to keep the concrete from coming in contact with the wood and putting my radiant heating on top of that.  The pour is a 3" pour so I would imagine I would have chairs going under the pex tubing to keep the tubing close to the surface.  Will I get a smell from the ice and water that the concrete is sitting on from when the heat is on?

    why didnt you just use.....

    15# roofers felt?  Yes they say never to use it......you'll smell it when it heats up.  But I have always used it, including my own house, and never had a problem.

    I never heard of doing it your way, so maybe someone else may be able to answer you.

    If it were me

     I would use 1" slab bolsters to hold the pex up off the floor. Most would just fasten it to the floor though. I like to see 360* tube burial for conduction, and getting the tubing closer to the top helps response time a little.
