Electric Underfloor Heating Film - Summary

Electric Underfloor Heating Film is a simple, ultra-thin, yet highly durable underfloor heating solution. Designed to be installed directly beneath floating floor coverings, this innovative product works by harnessing the electric resistance of the carbon heating element, delivering efficient, even warmth across any space.

With an impressive life expectancy of up to 50 years, it stands out as a reliable and long-lasting choice for modern infrared heating systems.

Product Description

Say goodbye to cold floors and clunky radiators. This Electric Underfloor Infrared Heating Film uses a printed graphite paste as resistance element, to generate warmth. Offering fast, consistent heat that spreads evenly across the surface.

With an ultra-slim thickness of just 0.34 mm, the heating film installs neatly beneath floating floor coverings with minimal impact on floor height. This makes it ideal for both new builds and retrofit projects. It can be used as a primary heating system or as a supplement to existing heating, depending on the property’s heat loss and layout.

The system heats up quickly, so warmth is typically felt within minutes rather than hours. Once installed correctly, the film is extremely durable and designed for long-term use, offering a reliable service life of up to 50 years.

Each heating zone is controlled by a thermostat with a floor temperature sensor, allowing precise, room-by-room temperature control. This improves comfort, protects floor coverings, and helps keep running costs efficient.

What is it suitable for?

This carbon underfloor infrared heating film is a versatile solution for a wide range of applications:

• Suitable as a primary heating system or supplementary underfloor heating
• Ideal for new builds and retrofit projects
• Designed to work directly beneath floating solid-core flooring systems such as laminate, engineered wood, and click-vinyl
• Can be used with carpet or soft vinyl flooring when installed together with an MDF baseboard system which creates a stable, heat-spreading surface above the film.

What is it not suitable for?

• Not suitable for installation under screed or self-levelling compound

  For screeded floors, a traditional electric heating mat should be used instead.

• Not suitable for use under ceramic or stone floor tiles
• Cannot be installed in UK “special locations” as defined by IET Wiring Regulations (BS 7671), including:
  o Bathrooms and shower rooms
  o Swimming pool areas
  o Saunas and other wet environments
  
  

  In these areas, alternative solutions such as electric heating mats or aluminium heating foil systems should be used instead.

How to Calculate Which Components You Need And How Much To Order

Installing electric underfloor heating with infrared heating film is straightforward if you break it down into components. Follow the steps below to calculate exactly what you need.

1. XPS Thermal Insulation Boards

   • Measure the total floor area of the room where you plan to install underfloor heating and new flooring.
   • Once you have the usable floor area, add 10% extra to allow for waste and cuttings.
   • Add the required quantity of XPS insulation boards to your basket.
   These boards act as thermal insulation to prevent heat loss into the subfloor and also serve as the underlay for your final floor covering. No additional underlay is required.

2. Carbon Infrared Underfloor Heating Film (You are currently on this page)

   • Calculate the heated floor area only (this is usually slightly less than the total insulated area). • Leave a 50–100 mm gap around the edges of the room and obstacles.
   • Do not include areas under built-in furniture such as kitchen units, fitted wardrobes, or fixed cabinetry.
   • Use different film widths (50 cm, 80 cm, 100 cm) to cover the area efficiently with minimal waste.
   • Select the correct output (80 W/m², 110 W/m², or 130 W/m²) based on insulation level and floor covering.
   Add the required length (in metres) of heating film to your basket.

3. Vapour Barrier

   • Cover the heating film completely with the vapour barrier.
   • Allow extra material for overlaps and cuttings.
   The vapour barrier provides a second insulation layer, creating a double-insulated (Class II) system and helping the installation comply with IET Wiring Regulations.

4. Heavy-Duty Adhesive Tape

   • Typically, 1–2 rolls per room.
   • Used to secure insulation boards, heating film, and vapour barrier in place.
   

5. Connection Crimps

   • Two crimps per heating film strip are required.
   • Supplied in packs of 10.
   

6. Crimping Tool

   • Required to secure the crimps safely to the heating film conductors.
   • If you don’t already have one, we recommend adding it to your order.
   

7. Termination Discs

   Used to seal the unconnected ends of the heating film.
   • Two termination discs per strip are required.
   • Supplied in packs of 20.
   

8. Cold Tail Leads (Live & Neutral)

   • Double-insulated flexible cable (brown and blue).
   • Used to connect the heating film to the thermostat circuit.
   • Typically one 10 m length of each colour per room (per 15 m²) is sufficient.
   

9. Thermostat

   • Choose a thermostat suitable for electric underfloor heating with a floor temperature sensor.
   • You will need one thermostat per room or heating zone.
