The best choice – Stone and ceramic

The best floor coverings for use with underfloor heating are hard surfaces such as stone and ceramic tiles as they have the least resistance and transfer heat effectively.

Stone and ceramic are the most thermally conductive of all floor coverings allowing the energy from the UFH heating tube to transfer quickly to the surface of the stone/tile.

Increasing the thickness of the tile will have little effect on the heat output, but it will slightly increase the heat up time.

With stone and ceramic tiles it is always advisable to use a de-coupling membrane and flexible adhesive to reduce the potential for any hairline expansion cracks.

  • Polished screed – By its nature, screed is very conductive and although unusual, it is well suited for use with under floor heating.
  • Limestone – Of all stone floor coverings, limestone requires the most care and attention during installation.
  • Slate – An extremely conductive natural finish, ideal for use with underfloor heating
  • Marble – An excellent conductor available in varying thickness

Opt for porcelain tiles, ceramic tiles or natural stone

In this instance, ceramic tile and natural stone floor finishes are a perfect partner for warm water underfloor heating – conducting heat efficiently and effectively. When choosing floor coverings for your underfloor heating, tiles or natural stone floor finishes are durable options that are easily maintained. A heated tile floor is also a good solution for kitchens and even open plan living areas where a continuous floor covering emphasises the sense of space.

The main criteria for the successful installation of ceramic tile or stone floor finishes, is a stable, level sub-floor. Tiling over underfloor heating is relatively straightforward once the sub-floor is level. When installing ceramic tiles and natural stone products as the final floor finish, Nu-Heat strongly recommends using a decoupling membrane.

Over time, it is possible for movement to develop in the sub-floor, which could result in cracked tiles. A decoupling membrane is a separation barrier between the tiles and the substrate, ensuring that any movement is isolated and does not affect the tiles or stone floor finish.

When choosing a ceramic tile or natural stone finish, it’s also important to choose tiles which are suitable for underfloor heating. The vast majority of companies will state which tiles in their collection are the best tiles for underfloor heating. Porcelain and ceramic tiles are good flooring materials to use with underfloor heating and present a more affordable option than natural stone.

Whatever tiles you decide to use, tiling over underfloor heating results in a warm room, quicker, and it also retains heat well. Having a heated tile floor means no more chilly bathrooms, utilities, entrances or conservatories.

Benefits of tiling over underfloor heating

There are many benefits to choosing to pair tiles with your underfloor heating tiles and to having a heated tile floor:

  • Tiles conduct heat evenly and efficiently from your underfloor heating to the surface of the floor
  • You can install ceramic tile or natural stone finishes on any floor level
  • Ceramic tile or natural stone floors provide a high-end finish
  • Tiled flooring is highly durable and long-lasting.
