Yes, you can install infrared heating film under tiles. The process involves preparing the subfloor, laying insulation, rolling out the heating film, and wiring it to a thermostat. A protective layer is applied before laying tiles with a compatible flexible adhesive. This method provides an efficient, invisible heating solution perfect for bathrooms and kitchens, delivering luxurious warmth through the floor.
Installing infrared heating film under tiles is an excellent way to create a warm, comfortable, and energy-efficient space. This step-by-step guide covers everything from preparing the subfloor and laying the insulation to wiring the system and tiling over it. Follow these instructions to ensure a correct and high-performing under-tile heating installation.
Installing infrared heating film under tiles is an efficient way to add warmth and comfort to your home. This guide will walk you through the process step-by-step, ensuring your under-tile heating system is installed correctly and performs efficiently.
Why Choose Infrared for Underfloor Heating?
Infrared heating is an energy-efficient solution that provides even heat distribution. It’s a great choice for modern homes because it:
- Saves energy with direct, radiant heat transfer.
- Eliminates bulky radiators, allowing for a sleek, minimalist design.
- Delivers consistent, luxurious warmth to tiled surfaces, ideal for bathrooms and kitchens.
- Helps prevent issues with damp and condensation.
Materials and Tools Required
- Infrared heating film kit
- Tile adhesive (flexible and compatible with underfloor heating)
- Insulation boards (e.g., XPS or thermal underlay)
- Moisture barrier or damp-proof membrane (if necessary)
- Thermostat and temperature sensors
- Tiles and standard tiling tools (trowel, spacers, etc.)
- Multi-meter for testing
- Scissors or utility knife
- Electrical connectors and insulation tape
Step-by-Step Installation Guide
Step 1: Prepare the Subfloor
A clean, flat, and stable subfloor is essential for efficient heat transfer and a professional tile finish. Ensure the surface is completely free of debris, is dry, and perfectly level. If you are installing over a concrete subfloor, it is critical to use a damp-proof membrane first to protect the system from any potential moisture.
Step 2: Add Insulation
Install thermal insulation boards across the entire subfloor. This step is vital as it prevents heat from escaping downwards and directs it upwards into the room, significantly enhancing the performance and efficiency of your infrared heating system. Secure the boards with a suitable adhesive, ensuring they are laid flat and evenly.
Step 3: Lay the Infrared Heating Film
Roll out the infrared heating film over the insulated surface. Use scissors to cut the film to the required lengths along the pre-marked cutting lines.
- Arrange the film so that the strips do not overlap.
- Maintain a gap of at least 50mm (2 inches) from all walls.
- Avoid installing the heating film under heavy, permanent fixtures like bathtubs or fixed cabinets to prevent any risk of overheating. Our ceiling-infrared-heaters-film is another option for different room layouts.
Step 4: Wire the Heating Film
Connect the electrical wires to the terminals on the heating film using the connectors provided in your kit. Follow the manufacturer’s wiring instructions carefully. Ensure all connections are secure, then insulate them thoroughly with the supplied electrical tape or heat-shrink tubing.
Step 5: Install the Thermostat and Temperature Sensor
Place the thermostat’s floor temperature sensor in a central location, ensuring it is positioned between two heating elements and does not cross over any of them. Connect the thermostat and sensor to the infrared heating system according to the manufacturer’s wiring diagram.
Step 6: Test the Heating Film
Before covering the system, it is crucial to test it. Use a multi-meter to check for continuity and resistance, ensuring the heating film is functioning correctly. This simple test can prevent costly and difficult adjustments later in the process.
Step 7: Apply a Protective Layer
Cover the heating film and wiring with a protective membrane or a thin layer of compatible self-leveling compound. This step safeguards the film from any damage during the tiling process and helps ensure a perfectly even distribution of heat under the tiles.
Step 8: Install Tiles Over the Heating Film
Use a flexible, heat-resistant tile adhesive to lay your tiles directly over the protective layer. Follow standard tiling techniques, using spacers to ensure proper alignment and even grout lines. Allow the adhesive to fully cure for the time recommended by the manufacturer before using the heating system.
Step 9: Final Testing and Setup
Once the tile adhesive has completely set, perform a final test of the infrared heating system to confirm everything is working correctly. Set your thermostat to the desired temperature and enjoy the comfort of your new under-tile heating. If you need help, contact now
Frequently Asked Questions (FAQs)
Can infrared heating be used under any type of tile?
Yes, infrared heating systems work exceptionally well under ceramic, porcelain, and natural stone tiles. The key is to always use a flexible tile adhesive that is specifically rated for use with underfloor heating systems to accommodate thermal expansion.
Is infrared under-tile heating expensive to run?
No. Infrared heating is highly energy-efficient because it heats the floor mass directly rather than the air. It uses less power compared to traditional heating methods to achieve the same level of comfort, often resulting in lower running costs.
Do I need a qualified electrician for installation?
While laying the insulation and heating film can be a DIY task, all electrical connections, including wiring the system to the thermostat and the main electrical supply, must be completed by a qualified electrician to ensure safety and comply with regulations.
How thick is the underfloor heating system?
The entire system, including the insulation board and heating film, is very thin—often adding only a few millimeters to the floor height. This makes it an ideal solution for renovations where floor height is a concern.
How long does the heating film last?
iHelios infrared heating film is a solid-state system with no moving parts. It is designed to be extremely durable and maintenance-free, with a lifespan of 30+ years. You can find more answers on our FAQ page.
