Electric underfloor heating systems can sit beneath stone, tile, wood or even carpeted surfaces. A series of electric wires installed beneath or within the floor finish provide the heating element. There are a number of product types available, including loose-fit wiring, modular systems and heating mats.

The design of the installation will depend on the space size and dimensions, how well insulated it is, the nature of the flooring structure and the type of flooring covering. Generally, on new-build projects, cables or electric heating sheets are fitted beneath the floor finish on a layer of screedand insulation which ensure the floor is level and that the heat travels upwards into the space.
