Personally, i would not lay tile direct onto a chipboard floating floor.......
As you've discovered from the earlier replies, several things either individually or collectively lead to the failures.
1. Tiling direct to chipboard - not good
2. Tiling to a floating floor - not good
3. Using a tiler who thinks doing the above is ok - not good
4. Adding heat into the equation - not good
Had you asked me to quote for this job, I would have politely declined.
Whilst I always want to see tiles used ahead of other finishes I think on this occasion I would consider an alternative.

You guys here in the UK tile onto plywood-chipboard alot which is unacceptable, you guys think if you use fexibile adhesive you are ready to go, that s wrong, 9 out of 10 jobs fail because of that. You need a subfloor, durock, ditra, screeds, hardibecker, etc... So you got hacked, it is a common thing here in the UK http://www.customtilemarblegranite.com/
Is that not the same with all underfloor heating ?Am i right in thinking your UFH is under the clipboard floor? If so you are heating the very thing the tiles are trying to stay fixed to.
The clipboard will expand and contract. Tiles aren't ever going to stay fixed for very long.
Might be a glued wood job instead of tiles?
