What Project Is Foil Heater Designed for?

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 and even heat distribution. The thermal properties of the reinforced aluminum foil used in the heater help to spread the heat evenly. Electric foil heater mats can be used both as a primary or secondary heating source in all rooms and projects that adhere to Building Regulations.

Foil layer acts as a continuous earth layer within the floor construction whilst also diffusing the heat evenly. Installed directly under the floor finish; no self-levelling required. Ideal for regular shaped rooms, where the 0.5m wide mats can be rolled out across the floor in parallel runs.

The Foil heater is made up of a fibre reinforced foil wrapped around a thin multi-strand, dual-core heating cable that is insulated with an advanced fluoropolymer. The foil provides a continuous earth layer within the floor construction whilst diffusing the heat away from the heating cable.

In some instances, you may need to cut, turn, and flip the mat to suit the room without touching the heating cable. More about the installation of a foil heating below.

Suitable Floor Covering for Foil Heater

The Warmup Foil Heater is an electric underfloor heating system designed for laminate, engineered wood and other floating floor finishes.

  • Laminate
  • Engineered wood
  • Other floating floor finishes.

Therefore most wood and laminate floors are compatible with the foil mats apart for the following exceptions: wood flooring thicker than 18mm, wood flooring with metallic strips as part of their locking systems as these metallic strips may damage the Foil mats and any wood floor with a pad already attached must not be used with the Warmup Foil mats.

The best way is to check with the laminate and wood flooring supplier that the floor material is compatible with electric foil heating.

Fitted between the insulating layer and the floating floor deck the heater adds negligible height to the installation. For wooden floors or similar, the thermal resistance should not exceed 0.15m² K/W.

Glued parquet flooring, carpets, vinyl and other resilient floor finishes can be laid over the Warmup Foil Heater by using Warmup Dual Overlay system to create a thin floating floor deck between the heater and the floor finish.

If homeowners wish to refurbish their rooms in the future, the floating floor finish installed over the foil heater can be easily lifted and replaced with a new finish if desired.

Insulation with the Foil Heater

Before installing a Warmup electric foil matting, 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 the floor furniture and people 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.

Improved savings can be achieved by using Warmup Insulated Underlay underneath the heater as this reduces the heat-up time by at least 50%, and results in cost-savings.

Installation of the Foil Heater

Foil floor heating is simple to install by rolling the mats out across the floor in parallel runs.

The Foil heater is made up of a fibre reinforced foil wrapped around a thin multi-strand, dual-core heating cable that is insulated with an advanced fluoropolymer. The foil provides a continuous earth layer within the floor construction whilst diffusing the heat away from the heating cable.

The Warmup Foil Mats are fitted directly on top of the Insulation, and directly under the wood laminate flooring. Always carry out a heat loss calculation prior to the installation to ensure the heater will provide enough heat for your room. Roll the foil matting out so that the lines are within 20mm of one another and 50mm of any wall.

Foil Heater Installation

Ensure you use the foil strips provided to bridge any gaps when cutting and turning the mats to suit the room. This is important to keep the earth intact. The foil heating mat must be completely flat. Care should be taken not to fold or crease the mats at any time during installation.

The floor finish can be laid directly on top of the heater or if there are likely to be heavy point loads such as cupboards, a soft Warmup Dual Overlay can be used between the heater and the floor finish to give extra protection for the heater.
