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.

No. The backerboard must be fully supported, and preferably adhered
to the subfloor.

You have it way backwards.

You need to do some reasearch.

1.) Thisnset
2.Backerboard
3.Screws
4.Thinset
5.) Heating Pad(on top of wet thinset, let it dry then lay tile like
normal)
6.)Thinset
7.)Tile

You'll use easy mat or 1/4 inch hardbacker not 1/2 inch

He is. That's why he's asking the question.

Unless there is a clearance problem there's no prohibition against
using 1/2" backer on the floor.

Doesn't seem to be too professional of an answer when you ignore what
the OP wrote. He is installing PEX, not electric radiant, so I'm not
sure why you're trying to redesign his system for him.

A goodly number of electric mat radiant manufacturer's prefer the mat
to be attached to the backerboard prior to the thinset being applied.
Wedi board is far superior to using backer board as it insulates the
subfloor and more heating dollars end up in the conditioned space
instead of in the structure - one manufacturer specifically recommends
Wedi under their mat.
