RAYCHEM R-BK-C-28.0M-550W/T0 - T2Black-20 floor heating cable, SZ18300328
The RAYCHEM T2Black-20 heating cable is an ideal solution for electric floor heating with a high output of 20 W/m, designed for installation under thick ceramic, marble and stone tiles. Thanks to the factory-terminated 2.5-meter power cord and delivery on a handy spool, installation is extremely easy and convenient. The product comes in a sturdy package that includes hot-melt adhesive and a protective tube for sensor installation, further simplifying the installation process. An ideal choice for the comfort and efficiency of heating in your home.
- Versatility of use - Suitable for any type of room, including especially those with irregular or complex shapes where heating mats may not be suitable.
- Function as the main heating source - Installed over the entire floor surface, it can act as the target heating source in the room.
- Fast heating - With a high nominal power of 20 W/m, the cable allows you to heat the floor quickly.
- Easy installation - Powered from one side, which makes installation quick and easy. In addition, the cable is terminated at the factory with a 2.5-meter power cord.
- Compact size - 4 mm thin, which allows it to be installed in the adhesive layer under tiles, without raising the floor level.
- Shower safe - Can be installed even in walk-in showers, providing thermal comfort in wet areas.
- Convenient installation - Each package contains hot melt adhesive with enhanced adhesion, which allows for simple and quick installation of the heating cable.
- Quality guarantee - The manufacturer offers a warranty that covers the repair of the heating cable in the floor. In the event of a manufacturing defect, the manufacturer agrees to locate, repair the defect and restore the floor to its original condition.
Installation recommendations:
- Floor tiles of standard size - install the heating cable directly in the adhesive layer under the tiles. The heating cable should be carefully taped, without leaving spaces with air. We recommend laying the heating cable at 135 mm intervals, obtaining 150 W/m².
- Large floor tiles, natural stone, marble - the heating cable should first be poured with a self-leveling screed with a thickness of min 5 mm (counting from the top of the cable), and only then stick the large panels. We recommend laying the heating cable at 135 mm intervals, achieving 150 W/m².
- Under floor panels, vinyl panels, linoleum, wood floors - the heating cable should be flooded with self-leveling screed, anhydrite screed with a thickness of 30 - 50 mm.
- In anhydrite or self-levelling screed - a cable with this heating power works best in screeds 30 - 50 mm thick.
