Hornisse electric underfloor heating cable 3.6 mm, length 37.8 m

Product detailed description

The Hornisse HO Cable/18-680 belongs to the range of two-core heating cables for screed. Its length is 37.8 m and power is 680 W at 230 V, with a linear power of 18 W/m and a cable diameter of 3.1–3.6 mm. It is suitable for floor heating in apartments, houses, as well as in office and service areas.

• The cable is laid in a concrete screed, so it can be easily hidden under tiles, panels or stone.
• Precise temperature control combined with high efficiency helps keep heating costs lower.
• Constant and even heat covers the entire floor, eliminating cold zones.
• The flexible cable is laid quickly, even in more complex spaces; it is suitable for apartments, houses and commercial buildings, in bathrooms, kitchens or as supplementary heating.
• Fluoropolymer and PVC insulation resist mechanical damage and moisture, increasing durability.
• Heating time is short – the desired room temperature is reached quickly.
• Shielding and good insulation minimize the risk of overheating.

Parameters of this cable

A length of 37.8 m at 18 W/m gives a power of 680 W – this is the data you will also find in the index 18-680. From the given power range, it is a medium size suitable for areas larger than the shortest pieces, but smaller than the longest ones.

The range includes cables with the same linear power of 18 W/m, differing in length and total power. This piece is highlighted in the table.

Application and installation

The cable is suitable for the following areas:

• floor heating in family homes and apartments,
• heating of commercial spaces, for example offices or service areas,
• places where additional heat is needed – near windows, balcony doors or in the bathroom.

When laying the cable, do not twist it and make bends with a radius of 50 mm; individual loops must not lie on top of each other. Installation should be carried out at a temperature of at least 5 °C. The two-core supply cable with a length of 2.5 m must be connected via a temperature controller and the connection should be done by a licensed electrician. The current drawn by the cable can be estimated from its power and voltage of 230 V; after installation, we recommend checking the cable resistance.
