The ADSV heating cable is fitted with full protective shielding to ensure maximum safety in all types of installations. High-quality insulation made from durable fluoropolymer (FEP) guarantees a long service life, and its very small diameter (just 3.4–4.2 mm) allows the cable to be laid even in a thin layer of adhesive directly beneath the tiles. The cable is two-core, with a single supply conductor, which significantly simplifies installation. It is the ideal choice for direct underfloor heating in both residential and commercial properties, as well as for renovations, if you want to have a warm floor at home without complex building work.

For optimal power design, it is available in three (or several) versions:

  • ADSV 5 and ADSV 7 W/m: designed specifically for heating low-energy and passive houses, with an underfloor heating power consumption of 40–70 W/m²
  • ADSV 10 W/m: a versatile standard for comfortable heating. It is the best choice for bathrooms where a pleasantly warm floor is required
  • ADSV 18 W/m: the most powerful version, designed for rooms with higher heat loss, where insulation is insufficient or the floor needs to be heated up as quickly as possible

This product is an electric local heater, falling under the scope of Regulation (EU) 2024/1103. The EcoDesign graphic symbol is an active link to mandatory information and conditions for its installation.
