The main difference between different flooring materials and their suitability for use with the system is the material’s thermal conductivity, meaning how quickly and efficiently heat generated transfers to the floor surface. The best flooring for underfloor heating is flooring with good conductivity as it heats up quicker, gives more heat output and is more efficient to run. However, this does not mean that less conductive materials could not be used with underfloor heating.
The best type of flooring to use is undertile heating. However, a compatible radiant heating system can be found for almost every floor finish.
With any flooring type you choose, including proper insulation will make the conductivity better.
