Electric heating cabel Hornisse 5,5mm (120m)
Code: HO HCABLE/15-1800Product detailed description
Electric underfloor heating cables installed beneath screed are commonly used in residential and commercial buildings to provide long-lasting and even heat distribution. These systems are particularly suitable for rooms with tile, panel or carpet flooring, where the screed acts as a thermal mass to retain and gradually release heat. The Hornisse 5.5mm cable is installed beneath a concrete or anhydrite screed layer, ensuring the heating elements remain hidden and protected. This installation method is ideal for new builds and renovations where a discreet and efficient heating solution is required.
Installers working with this system should be familiar with screed preparation, cable spacing and electrical connection procedures. The cable is designed for use in well-insulated rooms, where it can serve as either a primary or supplementary heating source. The low operating temperature of the cable ensures compatibility with standard screed materials and minimises the risk of overheating or damage to the surrounding structure.

Installation and connection
Installation of the Hornisse 5.5mm cable involves laying the cable beneath a screed layer, ensuring even spacing and secure positioning. The cable should be placed on a level base and fixed using clips or laths to prevent movement during screed pouring. The power supply cable is a three-core cable (two conductors plus earth), with a length of 2.5 m. This cable must be connected to a dedicated circuit with appropriate overcurrent protection. The maximum operating voltage is 230V, and the system must be earthed to meet electrical safety standards.
Common installation mistakes include incorrect cable spacing, which can lead to uneven heat distribution, and failure to allow sufficient clearance around fixtures and obstacles. Installers should also ensure that the minimum installation temperature of 5°C is maintained during installation to prevent material stress. After installation, the system should be tested for continuity and insulation resistance to verify correct operation before the screed is applied.
Compatibility and accessories
The Hornisse 5.5mm cable is compatible with standard underfloor heating control systems, including thermostats and room sensors. It can be used in conjunction with other Hornisse cables of the same type, such as the 15m, 25m, 40m, 60m, 80m, 100m, 2100m and 2325m variants. Additional components such as temperature sensors, control units and insulation boards may be required depending on the system design. Installers should ensure that all components are correctly matched to the cable's power output and operating parameters to maintain system efficiency and safety.
Technical background for designers
The Hornisse 5.5mm cable operates by converting electrical energy into heat through resistive heating elements. The low smoke zero halogen (LSZH) insulation ensures that the cable emits minimal smoke and no toxic halogens in the event of a fire. The dual-core construction and XLPE/PVC outer insulation provide mechanical strength and thermal stability. The cable is designed to be embedded in a screed layer, where the thermal mass of the screed enhances heat retention and distribution. The system's efficiency is influenced by the thickness of the screed, the insulation beneath the floor and the ambient temperature of the room.
Designers should consider the thermal conductivity of the screed material and the required heat output per square meter when planning the cable layout. The cable's maximum operating temperature of 45°C ensures compatibility with standard flooring materials and minimises the risk of overheating. The system's long service life and low maintenance requirements make it a cost-effective solution for both residential and commercial applications.
Service and operation
Once installed, the Hornisse 5.5mm cable requires minimal maintenance. Regular checks should be performed to ensure the system is operating within its specified parameters. This includes verifying the continuity of the cable and the insulation resistance between conductors and earth. Any signs of damage or irregular operation should be investigated and repaired by a qualified technician. The system should be operated according to the manufacturer's guidelines to ensure optimal performance and longevity.
Frequently asked questions
Can the Hornisse 5.5mm cable be used with anhydrite screed?
Yes, the cable is suitable for use with anhydrite screed. The thermal properties of anhydrite enhance heat retention and distribution, making it a compatible material for this system.
What is the maximum length of the power supply cable?
The power supply cable has a fixed length of 2.5 m. If a longer cable is required, an extension cable must be used, ensuring it is compatible with the system's voltage and current requirements.
Can the cable be cut to a shorter length?
No, the Hornisse 5.5mm cable is manufactured in fixed lengths and cannot be cut. The correct length must be selected based on the room's dimensions and required heat output.
Is the cable suitable for use in bathrooms?
Yes, the cable is suitable for use in bathrooms provided the installation meets the required electrical safety standards. The low operating temperature and waterproof insulation make it a safe option for wet areas.
