Tiles for Underfloor Heating: Which Tiles and Adhesive to Use
Porcelain and ceramic tiles conduct heat well, so they suit underfloor heating. Use a flexible, heat-rated adhesive and switch the heating on gradually after the adhesive has cured.
Which tiles work best
Porcelain is dense and conducts heat evenly, so it is the usual choice. Thinner tiles warm up faster than thick ones. Avoid tiles not rated for floors.
Adhesive and heat-up
Use a flexible, S1 or S2 rated adhesive suitable for underfloor heating. Let the adhesive and grout cure fully, then raise the temperature a few degrees a day, following the heating manufacturer's instructions.
