Electric heating cabel Hornisse 5,5mm (80m)
Code: HO HCABLE/15-1200Product detailed description
Electric floor heating cables installed beneath screed layers are commonly used in residential and commercial projects where long-term thermal stability and energy efficiency are required. These systems integrate seamlessly with concrete or anhydrite screeds, ensuring the heating elements remain concealed while providing uniform warmth across the floor surface. Installers typically handle the routing of cables during early construction stages or renovation works, ensuring the layout adheres to manufacturer guidelines and local regulations. The Hornisse 5.5mm cable is especially suited for rooms requiring auxiliary or primary heating, such as bathrooms, kitchens, living areas and other spaces where comfort underfoot is a priority.
Proper planning is essential to ensure the system operates efficiently and safely. The cable must be laid in a consistent pattern, avoiding sharp bends or overlaps that could lead to hotspots. The screed layer acts as a thermal mass, storing and gradually releasing heat, which enhances the system’s overall performance. The cable’s low-profile design allows it to fit within standard screed thicknesses, making it compatible with most modern construction practices.

Installation and connection
The Hornisse 5.5mm heating cable is installed beneath a screed layer, typically after the subfloor has been prepared and insulation applied. The cable should be unrolled and laid in a straight, parallel pattern, maintaining a consistent spacing to avoid uneven heat distribution. The minimum bending radius is 50 mm, and any sharp bends must be avoided to prevent damage to the insulation. After installation, the cable is connected to a 230 V supply using the included 2.5 m twin-core cable with an earth braid. The connection points must be secured in a junction box, and all electrical connections must comply with local wiring regulations. Key checks during installation include verifying the continuity of the cable, ensuring the correct spacing between conductors, and confirming that the cable is not damaged during handling. Common mistakes include incorrect routing, failure to account for thermal expansion, and improper grounding. Installers should also ensure that the cable is fully covered by the screed before final curing to protect it from mechanical stress.Compatibility and accessories
The Hornisse 5.5mm heating cable is compatible with standard concrete or anhydrite screeds and can be used with various floor finishes, including tiles, panels and carpets. For complete system functionality, it must be connected to a suitable thermostat and power supply. Additional components such as temperature sensors, control modules and junction boxes may also be required, depending on the specific application. Related products include the Hornisse 5.5mm heating cable in lengths of 15m, 25m, 40m, 60m, 100m, 120m, and others. These variants allow for flexible system design and can be combined as needed to cover larger floor areas or multiple rooms.Technical background for designers
The Hornisse 5.5mm heating cable operates by converting electrical energy into heat through resistive heating. The cable is constructed with a twin-core design, insulated with low-smoke zero-halogen (LSZH) material, and protected by an outer layer of XLPE and PVC. This combination ensures durability, fire safety and minimal emissions in case of combustion. The cable’s design allows for efficient heat transfer to the surrounding screed, which acts as a thermal storage medium, maintaining warmth even after the system is turned off. Designers should consider factors such as room insulation, floor covering type, and desired heat output when selecting and laying the cable. The system’s efficiency is maximised when integrated with a programmable thermostat and zoning controls, allowing for precise temperature regulation. Longevity and performance depend on correct installation, adequate thermal mass and regular monitoring of system parameters.Service and operation
Once installed, the Hornisse 5.5mm heating cable requires minimal maintenance. Regular checks should include verifying the functionality of the thermostat, inspecting the integrity of the cable and ensuring the system remains free from physical damage. Any irregularities in heat distribution or electrical performance should be investigated promptly. Since the cable is embedded in the screed, access for repairs is limited, and any faults should be addressed by qualified personnel. No scheduled service intervals are specified in the technical documentation.Frequently asked questions
Can the Hornisse 5.5mm cable be used in a bathroom?
Yes, the cable is suitable for use in bathrooms provided it is installed beneath a non-conductive screed and connected to a properly grounded circuit. It must also be paired with a waterproof thermostat and appropriate insulation.
What is the maximum length of the Hornisse 5.5mm cable available?
The maximum continuous length available is 80m. Longer runs require multiple segments or additional control units to ensure safe and efficient operation.
Is the Hornisse 5.5mm cable compatible with anhydrite screed?
Yes, the cable is specifically designed for use with both concrete and anhydrite screeds. It is important to ensure the screed thickness is sufficient to provide proper thermal mass and mechanical protection.
How is the Hornisse 5.5mm cable connected to the power supply?
The cable is connected via a 2.5 m twin-core cable with an earth braid. The connection must be made in a junction box, and the system should be tested for continuity and insulation resistance before commissioning.
