I'm installing electric, radiant floor heating. The manufacturer told me that the heating element gets up to about 200 degrees. He could not answer my real question which was:
Will putting a layer of roofing felt down on the subfloor present a fire hazard? That is, wood subfloor, felt, heating element/mortar, tile.
Since there is no oxygen, I wouldn't expect any flames (but you never know.) Also, roofs get pretty hot in the summertime - but do they reach 200* under the shingles?
What do you think?
