Also why use such non (heat) conductors - tiles and wood - great for hot spots! I would have thought that a nice *single* thin piece of steel (or copper or aluminium) shaped and placed over the wood and *then* tile over the metal would be better. Any single hot tile then heats up the metal back which evens out the heat over its entire surface, and the wood does not get to any dangerous temperatures. Another thought would be to add some simple K thermocouples embedded in the tile cement (a K thermocouple is just a very thin pair of special wires welded together at the end - takes no room, would be easy to embed) and hiding the open end somewhere close by - then an appropiate meter could be used check the temperature behind the tiles.
