Hornisse – electric heating cable 5.5 mm, length 160 m
Code: HO HCABLE/15-2325Product detailed description
Hornisse HO HCable/15-2325 is the most powerful cable in the HO HCable/15 underfloor heating range. It achieves a power of 2325 W at 230 V, draws 10.1 A, and has a resistance of 22.8 Ω. It is laid under a concrete or anhydrite screed and, at a specific power of 15 W/m, creates even, reliable, and economical floor heating. The product designation indicates 160 m, while the manufacturer's specifications for this model state the cable length as 155 m.
The previous model in the range has a length of 140 m. It differs from this one in length, power, current, resistance, and weight; diameter, insulation, and supply cable are the same.
Main Features
- Highest power in the range: 2325 W at a specific power of 15 W/m, suitable for larger heated areas.
- Thermal inertia: A concrete or anhydrite screed stores heat and gradually releases it, ensuring stable and long-lasting heating.
- Invisible installation: Everything is hidden in the floor, so the interior design remains intact.
- Mechanical protection: The screed protects the cable from external influences.
- Compatibility: Suitable with tiles, panels, and carpets.
- Low-smoke insulation: LSZH core without halogens, XLPE and PVC sheath.
- Energy efficiency and durability: Low operating costs and minimal maintenance.

Application
The cable is suitable for use in single-family homes, apartments, and commercial spaces. It is appropriate for bathrooms, kitchens, living rooms, and other rooms with floor heating. It is especially recommended as an auxiliary or main heat source in well-insulated rooms, both in new constructions and during the modernization of existing heating systems.
Note on Sizing
With the most powerful variant in the range, correct dimensioning of the electrical circuit is particularly important, as the cable draws 10.1 A at a power of 2325 W. Therefore, installation should be entrusted to a qualified professional who will select the appropriate fuse and thermostat. The cable core is insulated with LSZH material, and the outer sheath consists of XLPE and PVC, so after pouring the screed, the cable is protected by multiple layers of insulation.
Installation and Operation
Wiring should be carried out by a qualified electrician following current regulations. Do not bend, cross, overlap, or twist the cable with a radius less than 50 mm. The installation temperature must not be lower than 5 °C. With a long cable, it is especially important to check the resistance before laying, after laying, and after pouring the screed, and compare it with the value of 22.8 Ω.
