Unfortunately, in most cases where tiles already exist over underfloor heating, to change the tiles you would have to strip them and the underfloor heating system and replace both. It would be possible to tile over the existing tiles without affecting the output too much if you are using tiles with good thermal conductivity, however, most tiles are ceramic which is more of an insulator. If tiles have already been installed over underfloor heating it would be risky to attempt to remove them, because you could potentially damage the underfloor heating system underneath. Turning on the system too soon will cause the adhesive to dry up too quickly, which will make it weak.Ĭan you tile over tiles that were installed over underfloor heating? This is because the adhesive needs to be allowed to cure. Tiles can expand at a different rate to screed and adhesives and this causes stress between the tiles and the adhesive.Īnother issue with tiling directly over underfloor heating is the weakening of grout and adhesive if the underfloor heating system is turned on too soon. In the worst case scenario, with instability and even movement in the floor, the tiles could end up cracking. The main challenge underfloor heating installers face is creating a surface which is flat and stable enough for tiles to be laid over.Īny undulations or issues with the subfloor can easily result in issues, where the imperfections in the subfloor are carried through to the final surface.

What are the common problems with tiling over wet underfloor heating? Other finishes such as carpets or vinyl will typically require an intermediate board layer prior to the finish being installed. Tiles and wood flooring can be laid directly over this system. Over a structural timber floor, panels should be fixed down with AmbiDeck fixing washers, approximately 6 per board. Over a concrete floor, we recommend laying the AmbiDeck 18 panels over a combed layer of flexible tiling adhesive. Additional pipework channels can easily be routed/grooved into the panel.ĪmbiDeck 18 must be laid onto a flat and level subfloor, which can either be concrete or timber-based. It is grooved to take 12mm UFH pipework, with a radius return grooved into each panel, making the panel universal. The face of the panel is cement-coated, making it rigid and durable. And finally, can tile be laid directly over the system?Įnter, AmbiDeck 18 – designed exclusively by Ambiente Systems UK, this new system incorporates an insulation layer within a low-profile UFH system– combining a low-profile system with excellent performance and the ability to lay tiles directly over!ĪmbiDeck 18 consists of a high-density XPS insulation panel, 18mm thick. While on the other hand, there is a drive to incorporate some insulation, to maximise heat output and minimise downward heat loss. When advising on retrofit underfloor heating systems, there is a continual trade-off of parameters – on the one hand, there is a requirement to keep the system as slim as possible to minimise loss of floor-to-ceiling height. A retro-fit underfloor heating system answering all of the challenges!
