What project is the 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 heat distribution with the thermal properties of the reinforced aluminum foil used in the heater helping to spread the heat evenly. 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.
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.
If you are using softer floor coverings such as Vinyl or carpet the foil heater must be used in conjunction with the Warmup Dual Overlay System. The Dual Overlay subfloor provides protection for the Foil Heater while allowing the heat to easily pass through to the final floor finish providing maximum comfort.
However, note that Dual Overlay must not be used in ‘wet’ rooms (such as bathrooms). If you are using vinyl or carpet in a wet room, consider using compatible electric systems such as the DCM-PRO, StickyMat or Loose Wire systems; all installed with a self-levelling compound for waterproofing.
Key Benefits
Installed directly under the floor finish
No self-levelling requiredNo raise to floor levels
Super-thin, fully earthed flat aluminum foil will not raise floor levelsFits around objects
Wire based system, can be adapted to fit around objects, no need for complicated wiring
Suitable Floor Coverings for the Foil Heater
The Warmup Foil Heater is an electric underfloor heating system designed for:
- Laminate
- Engineered wood
Certain wood flooring finishes are not recommended for use with Warmup foil mats including wood flooring thicker than 18mm, wood flooring with metallic strips as part of their locking systems (these metallic strips may damage the Foil mats) or any wood flooring with a pad already attached.
In case you have any concerns, check with your chosen flooring supplier that your flooring option is compatible with an electric Foil Heating System.
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.
Suitable floor coverings for the Foil Heater with Dual Overlay
With specific floor finishes, the Foil Heating System is designed to be used in conjunction with Warmup’s Dual Overlay System; a free-floating subfloor that protects the system.
Suitable floor coverings for the Foil Heater with Dual Overlay:
- Carpets
- Vinyl
Glued carpets, vinyl and other floor finishes can be laid over the Warmup Foil Heater by using the Warmup Dual Overlay system to create a thin floating floor deck between the heater and the floor finish (not suitable for wet rooms as the Dual Overlay may expand due to excessive moisture).
Some flooring manufactures only allow the use of underfloor heating systems with their flooring when the system is embedded within a screed / levelling compound. It is important that you check with the Vinyl or carpet flooring manufacturer on the types of underfloor heating system that are suitable.

Suitable Floor Coverings for the Foil Heater
The Warmup Foil Heater is an electric underfloor heating system designed for:
- Laminate
- Vinyl
- Engineered wood
- Carpet
- Other floating floor finishes.
Therefore most floor finishes are compatible with the foil mats apart from the following exceptions:
Vinyl or carpet flooring should not be used with a Foil Heater in ‘wet’ rooms such as bathrooms.
Certain wood flooring finishes are not reccomended for use with Warmup foil mats including wood flooring thicker than 18mm, wood flooring with metallic strips as part of their locking systems (these metallic strips may damage the Foil mats) or any wood flooring with a pad already attached.
In case you have any concerns, check with your chosen flooring supplier that your flooring option is compatible with an electric Foil Heating System.
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.
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
Electric Foil underfloor 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 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.
Ensure you use the separate 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.
If using laminate or wood, the floor finish can be laid directly on top of the heater or if using vinyl or carpet flooring, the Warmup Dual Overlay system can be used between the heater and the floor finish to give extra protection for the heater (only suitable for ‘dry’ rooms). Dual Overlay is also reccomended to protect against heavy-load areas, such as large cupboards that may add excessive pressure to the heater.
