Electric heating cabel Hornisse 3,6mm (155m)

Product detailed description

Electric heating cables embedded in screed layers are commonly used in residential and commercial buildings to provide efficient and even floor heating. These systems are particularly suitable for new constructions or renovations where screed is part of the floor structure. The installation involves laying the cables directly onto the screed surface before the final floor covering is applied. This method ensures the heating elements are concealed and evenly distributed, making them ideal for use under tiles, panels, or stone. The Hornisse 3.6mm heating cable is designed for such applications, offering a reliable solution for maintaining thermal comfort in a variety of spaces, including living areas, kitchens, bathrooms, and commercial premises such as offices and service areas.

When planning an underfloor heating system, it is important to consider the thermal load of the space, the type of flooring, and the insulation properties of the building. The Hornisse 3.6mm cable is suitable for use in both residential and commercial environments, where it can serve as a primary or supplementary heat source. It is particularly effective in areas prone to cold spots, such as near windows, doors, or in rooms with high ceilings. The cable’s design allows for flexibility in installation, enabling it to be laid in complex patterns to suit the specific layout of the room.

Technical parameters

The technical parameters of the Hornisse 3.6mm heating cable are essential for determining its suitability for a specific installation. The cable operates at 230V and has a power output of 18W per meter, making it appropriate for rooms requiring moderate heating. The total length of the heating element is 154.2m, and the cable is constructed with a fluoropolymer-insulated core and a PVC outer sheath. The maximum operating temperature of the cable is 45°C, and the minimum installation temperature is 5°C. These values are critical for ensuring the cable functions within safe limits and maintains efficiency over time. The resistance and current values provided in the table are useful for calculating the electrical load and ensuring compatibility with the control system.

Installation and connection

Installation of the Hornisse 3.6mm heating cable involves laying it directly onto a screed surface that is at least 3.6mm thick. The cable should be spaced evenly according to the manufacturer’s guidelines to ensure uniform heat distribution. The power supply is connected via a two-core cable with an earthing braid, with a standard length of 2.5m. The connection points must be accessible for inspection and maintenance, and the cable must be secured to prevent movement during the screed curing process. It is important to avoid sharp bends or kinks, as the minimum bend radius is 50mm. Common installation mistakes include incorrect spacing, failure to secure the cable, or using an incompatible control system. After installation, the system should be tested for continuity and insulation resistance to ensure there are no faults before the final floor covering is applied.

Compatibility and accessories

The Hornisse 3.6mm heating cable is compatible with standard underfloor heating control systems that operate at 230V. It is typically used in conjunction with thermostats, temperature sensors, and relay modules to regulate the heating output. Additional components such as junction boxes, insulation boards, and expansion joints may be required depending on the installation. Related products include the Hornisse 3.6mm electric heating cables with lengths of 15m, 22.2m, 37.8m, 44.4m, 61.1m, and 67.8m. These can be used in combination to cover larger areas or to replace sections of an existing system. It is important to ensure that all components are from the same manufacturer to maintain compatibility and system performance.

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 that the heat is efficiently transferred to the surrounding screed and floor covering, while the PVC outer sheath provides mechanical protection and resistance to environmental factors. The cable’s construction allows it to withstand normal installation stresses and maintain performance over time. The system’s efficiency is influenced by the thermal conductivity of the screed, the type of flooring, and the insulation of the building. To maximize efficiency, the cable should be installed in a well-insulated space with minimal thermal bridging. The operating temperature of the cable is limited to 45°C to prevent overheating and ensure long-term reliability.

Service and operation

Regular inspection and maintenance are not typically required for the Hornisse 3.6mm heating cable, as it is designed for long-term use with minimal intervention. However, it is recommended to periodically check the system for signs of damage, such as insulation wear or mechanical stress. The control system should be tested to ensure it is functioning correctly, and the electrical connections should be inspected for corrosion or looseness. If the system is not operating as expected, a continuity test and insulation resistance test should be performed to identify any faults. The cable is not designed for disassembly, so any damaged sections should be replaced with a new cable of the same specification.

Frequently asked questions

Can the Hornisse 3.6mm heating cable be used with a standard thermostat?
Yes, the cable is compatible with standard thermostats and temperature control systems that operate at 230V. It is important to ensure the thermostat is correctly configured to regulate the heating output.

Is the Hornisse 3.6mm heating cable suitable for use in bathrooms?
Yes, the cable is suitable for use in bathrooms as long as it is installed in a dry screed layer and the control system is located outside the wet area. The cable is resistant to moisture and does not require additional waterproofing.

Can the Hornisse 3.6mm heating cable be cut to a shorter length?
No, the cable is not designed to be cut or modified after manufacturing. It should be selected based on the required length to avoid the need for splicing or shortening.

What is the maximum operating temperature of the Hornisse 3.6mm heating cable?
The maximum operating temperature is 45°C. Exceeding this temperature can reduce the cable’s lifespan and may cause damage to the insulation or surrounding materials.
