This product is an electric underfloor local space heater that fulfils the Regulation (EU) 2024/1103. The mandatory information and conditions for its installation are available through the link within the EcoDesign logo. |
The heating cable or radiant wire is supplied in a spool format, pre-connected to a cold tail (power supply cable). The same heating cable can also be supplied as a heating mat, where the cable is pre-attached to a fiberglass mesh to facilitate installation.
For underfloor heating installations (residential and commercial), we have developed the ADPSZV cable—a twin-conductor heating cable with helical shielding.
Most heating cables or radiant wires are resistance cables. Their core consists of an electric resistance with a constant linear resistance value, which heats up when electrical current flows through it.
Each application has a specially designed range of cables, where both the resistance type and cable length are adjusted to achieve a specific linear output (power per meter of cable), delivering the appropriate heat and temperature.
For this reason, heating cables are only sold as finished elements, pre-connected to a power cable with a defined power rating and length. Heating cables cannot be cut after production, as this would reduce their total resistance, increase their linear power, and expose the cable and installation to excessive temperatures.
Our cables are twin-conductor (two resistances in parallel), with the circuit factory-sealed at one end of the heating element. The power supply cable is located at the opposite end and is connected to the junction box, making installation easier.
The heating cable/radiant wire is made up of several layers to ensure proper insulation of the resistive elements and provide the necessary performance characteristics for each application, in compliance with international standards.
For use in damp areas (bathrooms/kitchens) or outdoors, a fully surrounding electrical shield connected to ground is mandatory, ensuring maximum safety for the user.
For all applications, a specific heating requirement can be defined to achieve the desired comfort and temperature level depending on the environment. In underfloor heating, this is expressed as the installed power per square meter. Based on the type of room, climate, and home insulation, a power range between 60 and 150 W/m² is typically considered.
Each surface power output can be achieved using more or less cable length, depending on the cable’s linear power (power per meter of cable). Different linear power ranges are available (e.g., 10 W/m, 17.9 W/m, etc.) for each type of cable.
If the installation is carried out directly beneath the flooring, it is recommended to use a longer cable with lower linear power to reduce the spacing between cable loops (~8 cm) and avoid cold spots.
In the case of semi-storage systems (cable under 3–4 cm of screed) or full-storage systems (cable embedded in the concrete structure), wider loop spacing and higher cable linear power can be used. Conversely, the same cable can provide different surface power outputs depending on the spacing between loops—distributing the same total power across a larger or smaller area.
This same flexibility can be applied within a single room by varying the spacing in different zones of the circuit, allowing for uneven heat distribution as needed.
