Foil underfloor heating is an ideal heater for larger areas and for use with so-called floating floors such as laminate, vinyl, engineered wood, and carpet.

Simple to install, the Foil Heater delivers a consistent heat distribution with the thermal properties of the reinforced aluminum foil used in the heater helping to spread the heat evenly.

Warmup 140W Electric Under Wood Heating Foil Mat Kit

How Does the System Work?

The foil layer acts as a continuous earth layer within the floor construction whilst also diffusing the heat evenly and away from the heating cable itself and because it is installed directly under the floor finish, no self-levelling is required.

Ideal for regular shaped rooms, the 0.5m wide foil mats can be rolled out across the floor in parallel runs. In some instances, you may need to cut, turn, and flip the mat to suit the room without affecting the heating cable. Read more about the installation of the Foil Heating System below.

Electric foil heating mats can be used both as a primary or secondary heating source in all rooms and projects that adhere to Building Regulations.


Insulation with the Foil Heater

Before installing a Warmup electric foil heating system, always check the subfloor has adequate thermal insulation. This is particularly important where the foil heaters will be used as a primary heat source.

The heater must be installed on top of a suitable soft insulation material. This is necessary to prevent the heater from being damaged when the weight of furniture and people on the floor are added. Insulation material should be at least 6mm thick and suitable for use with electric underfloor heating.  If Warmup Insulation board or similar is used, a soft underlay must be added to ensure the heater is not in contact with the cement facing of the board.
