Electric heating cabel Hornisse 3,6mm (22,2m)

Product detailed description

Electric heating cables embedded in screed are commonly used in residential and commercial buildings to provide efficient and even floor heating. These systems are installed beneath various floor types, including tiles, panels, and stone, and are particularly suited for areas requiring additional heat, such as near windows, doors, or in bathrooms. The Hornisse 3.6mm cable is designed for integration into screed layers, ensuring a neat and concealed installation. It is suitable for both new builds and retrofit projects, offering a reliable solution for underfloor heating in a variety of applications.

Installers working with this system must ensure the screed thickness is at least 3.6mm and that the ambient temperature during installation is above 5°C. The cable must be laid in a consistent pattern to ensure even heat distribution and must be connected to a 230V power supply with appropriate control and safety devices. Careful planning is essential to avoid overlapping or sharp bends, which could affect performance or cause damage.

Technical parameters

Installation and connection

Installation begins with preparing a clean, level screed surface. The cable is laid in a zig-zag or serpentine pattern, ensuring even coverage and avoiding sharp bends. The minimum bend radius is 50mm. The cable must be secured in place using clips or ties to prevent shifting during screed pouring. The power supply is connected via a 2-core cable with an earth wire, with a maximum length of 2.5m. Installers should verify that the total resistance of the cable matches the expected value for the selected length to ensure correct operation. Common mistakes include incorrect spacing, overlapping cables, and failure to secure the cable properly, which can lead to uneven heating or system failure.

Compatibility and accessories

This heating cable is compatible with standard 230V electrical systems and requires a thermostat for temperature control. Additional components such as thermostats, temperature sensors, and circuit breakers must be ordered separately. Related products include the Hornisse 3.6mm cables in lengths of 15m, 37.8m, 44.4m, 61.1m, 67.8m, 83.3m, and others. These can be combined to cover larger areas or used individually for smaller spaces. The system is suitable for integration with existing heating systems as a supplementary heat source.

Technical background for designers

The Hornisse 3.6mm heating cable operates on the principle of resistive heating, where electrical current passing through the conductive core generates heat. The fluoropolymer insulation ensures even heat distribution and protects against electrical faults. The PVC outer sheath provides mechanical protection and resistance to environmental factors. The cable is designed to be embedded in a minimum 3.6mm screed layer, which acts as a thermal conductor to distribute heat across the floor surface. The efficiency of the system depends on the screed thickness, floor covering, and ambient conditions. Proper spacing and layout are essential to prevent hotspots and ensure uniform heating. The cable's maximum operating temperature of 45°C ensures safety and prevents overheating.

Service and operation

Regular visual inspections are recommended to check for signs of damage, such as cracks or abrasions in the outer sheath. The system should be tested periodically to ensure the thermostat and control devices are functioning correctly. No specific service intervals are required, but any faults should be addressed immediately to prevent further damage. The cable is designed for long-term use and requires minimal maintenance. In the event of a fault, the entire system should be disconnected from the power supply before any repairs are carried out.

Frequently asked questions

Can the Hornisse 3.6mm cable be used in wet areas such as bathrooms?
Yes, the cable is suitable for use in bathrooms and other wet areas due to its resistance to moisture and high-quality insulation.

What is the maximum length of the heating cable that can be used in a single installation?
The maximum length of the Hornisse 3.6mm cable in a single installation is 154.2m, depending on the required power output and room size.

Is the cable compatible with thermostats?
Yes, the cable must be connected to a thermostat for temperature control to ensure efficient and safe operation.

What is the minimum ambient temperature for installation?
The minimum ambient temperature for installation is 5°C to ensure proper adhesion of the cable to the screed and prevent damage during the curing process.
