I would like to install ceramic tile over radiant floor tubing.

Can I do this with acceptable results?

1. Install PEX on top of existing subfloor and use furring strips of
appropriate thickness between loops.

2. Install 1/2" concrete backer board on top of furring strips.


Heat transfer plates and thermal mass not an issue at this point. I am
more concerned about structural integrity, i.e., will back board be
strong enough to support tile without flexing or cracks in either tile or
mortar.
