Composite heating foil Hornisse 50m² (0.5 x 100m)

Product detailed description

The Hornisse composite heating foil HO-305 is commonly used in dry construction for electric floor and wall heating systems. It is particularly suitable for residential and commercial buildings where low installation height and rapid thermal response are required. Installers typically integrate it into new constructions or renovations without the need for major structural modifications. The system operates via infrared radiation, ensuring even heat distribution without air movement or cold spots. It is compatible with standard electrical infrastructure and can be controlled via thermostats or building management systems.

Its low thickness of 0.338 mm and installation height of 5 mm make it ideal for use over existing floor coverings. The system is not suitable for wet areas and requires a dry environment to function optimally. The foil is cut in 25 cm increments and can be installed in sections up to 20 m in length per run. This allows flexibility in adapting to different room sizes and layouts.

Technical parameters

Code	HO-305

The foil has a power output of 120 W/m² and 50 W/m, with a maximum operating temperature of 35°C. These parameters are essential for sizing the system to match the required heat load of the space. The 230V supply voltage is standard for most European electrical systems. The maximum length of a single strip is 20 m, and the maximum power per strip is 1200 W, which must be considered when planning the electrical circuit and load distribution.

Installation and connection

The installation process involves laying the foil on a clean, dry surface, typically over an existing floor. The foil must be positioned in straight lines without overlapping. The recommended spacing between strips depends on the desired heat output and room dimensions. The foil is connected using compression connectors, and the electrical connection must be made with a 230V supply. It is essential to ensure that the foil is not cut in the middle of a heating element but only at the 25 cm increments marked on the foil. Common installation mistakes include incorrect cutting, overlapping strips, and failure to secure the foil properly. The foil should be covered with a thin layer of underlay or flooring material to protect it during the finishing stages. It is also important to avoid placing heavy objects directly on the foil during installation. After installation, a continuity test should be performed to verify the electrical integrity of the system before connecting it to the power supply.

Compatibility and accessories

The Hornisse composite heating foil is compatible with standard dry construction systems and can be used with various floor coverings such as laminate, vinyl, and tiles. It requires a thermostat for temperature regulation and may need an electrical circuit breaker to protect the system. Additional components such as thermostats, circuit breakers, and control panels should be ordered separately. Related products include the Hornisse composite heating foil with widths of 0.5 m and 1 m, available in lengths from 1 to 100 m.

Technical background for designers

The composite heating foil operates via infra-red radiation, which heats surfaces and objects directly rather than the air. The foil is constructed from multiple layers of material, including high-quality copper strips and a protective PET film. The copper strips are responsible for the electrical conductivity and heat generation, while the PET film provides mechanical protection and prevents abrasion. The foil’s low thickness and flexibility allow it to conform to irregular surfaces and be installed without raising the floor level. The system’s efficiency is influenced by the thermal properties of the materials above and below the foil. A thin layer of flooring material is recommended to ensure even heat distribution and prevent localized overheating. The maximum operating temperature of 35°C is designed to prevent damage to the flooring and ensure user comfort. The system is intended for dry environments and should not be used in areas with high humidity or water exposure.

Service and operation

The Hornisse composite heating foil requires minimal maintenance due to the absence of moving parts. Regular checks should include verifying the electrical connections and ensuring that the foil is not damaged or cut incorrectly. The system does not require periodic service intervals, but it is advisable to perform a continuity test during installation and after any major renovation work. If the system is not functioning as expected, the first step is to check the thermostat and electrical connections. If the issue persists, the foil should be inspected for damage or overheating.

Frequently asked questions

Can the Hornisse composite heating foil be cut to custom lengths?
Yes, the foil can be cut in 25 cm increments as marked on the product. It should not be cut in the middle of a heating element.

Is the Hornisse composite heating foil suitable for use with tile flooring?
Yes, the foil is compatible with tile flooring as long as the installation is done according to the manufacturer’s guidelines. A thin layer of underlayment is recommended to protect the foil during tile installation.

Can the Hornisse composite heating foil be installed over an existing floor?
Yes, the foil can be installed over an existing floor without the need for demolition. It is designed for low installation height and is suitable for use in renovations.

What is the maximum length of a single strip of Hornisse composite heating foil?
The maximum length of a single strip is 20 m. Longer lengths require multiple strips connected in parallel or series, depending on the electrical load and circuit capacity.
