The tile is a good conductor of heat so it helps us in this particular case.
But we should avoid small joints to withstand the contractions-
expansions that will be present and the adhesive should be elastic to allow for different contraction in the tile than in the substrate

— Lefteris Arabatzis
Heating is achieved by conduction, radiation and convection. The use of underfloor heating dates back to the Neoglacial and Neolithic periods.
