Installing Carbon Film Underfloor Heating

Installing carbon film underfloor heating is a precise process that requires careful planning and electrical connections. Here’s a step-by-step guide:

1. Plan & Measure the Area

• Decide Where to Install: Suitable for laminate, engineered wood, or vinyl flooring (not for tiles or carpet without an underlay).
• Measure the Room: Leave a 5-10 cm gap from walls and fixed furniture to prevent overheating.
• Check Power Supply: Ensure the electrical circuit can handle the additional load.

2. Prepare the Subfloor

• Clean & Level: The surface must be dry, smooth, and free from debris.
• Install an Insulation Layer: Use XPS boards or thermal underlay to improve efficiency and prevent heat loss.

---

3. Lay the Carbon Film

• Cut to Size: Cut the heating film along designated cut lines (usually marked by a scissor symbol).
• Place the Film Strips: Lay them copper-side down, ensuring no overlaps. Maintain gaps where necessary.

---

4. Connect the Electrical Components

• Attach Conductive Clips: Connect them to the copper strips on the heating film.
• Insulate the Connections: Use bitumen insulation tape to cover exposed electrical parts.
• Run the Wires: Connect to a thermostat and ensure proper wiring to the power supply.

5. Install a Floor Sensor & Thermostat

• Place the Sensor: Position it between two heating strips to monitor temperature.
• Connect to Thermostat: Follow the manufacturer’s wiring diagram to attach the sensor and heating film.

6. Test the System

• A qualified electrician is needed.
• Check Voltage & Continuity: Use a multimeter to confirm proper connections.
• Power On & Monitor: Ensure even heating before installing the final flooring layer.

7. Install the Final Flooring

• Lay the Flooring: Install laminate, engineered wood, or vinyl as per the manufacturer’s guidelines.
• Avoid Nails or Screws: These can damage the heating film.
