The damage of the heating cable insulation due to the steel reinforcement led to a short circuit and complete interruption of the cable.

The most common causes of failures

We’ve prepared a new chapter "The most common causes of failures" for you, where we will gradually add illustrative examples of the mistakes, that can occur during the installation of our products. You can find the chapter in the Support section.

The cut in the heating cable was repaired with a breakable terminal block and insulated with black electrical insulating PVC tape. As the several layers of adhesive tape show, the person in question certainly didn´t want to underestimate the repair….

Unprofessional repairs

The unprofessionally performed repair of heating cables results, unnecessarily, in significantly higher damage.

This is one case when an investor asked for our opinion before the floor was covered. The heating cables are insufficiently attached, the clips are too far apart, and the cable is “floating” on the floor. If the screed had been poured, the cables may have come into contact with one another or even crossed, which would have led to the overheating and interruption of the cable. In the right half of the photo, there are loose cables in the immediate vicinity of the floor probe gooseneck, which would have...

Incorrect installation

The most common mistakes when laying heating cables and mats

Virtually the whole connector has been pulled into the perimeter wall, where there is no reliable heat dissipation. The second mistake is the bending of the heating cable immediately after the connector – heating and the different expansion of materials in the bend create cyclic mechanical stress on the joint, which can lead to its interruption

Heating cable connectors

A very common mistake is the damaging or incorrectly placement of heating cable connectors.

PSV cables with stranded resistance from 1. 1. 2016

Since the beginning of 2016, we have improved the structure of one of our bestselling PSV heating cables.

With our cables you'll be a step ahead…

FENIX is introducing halogen-free power supply leads (under the Halogen FREE logo) for its heating mats and heating cables designed for floor heating.

Heating cable for semi-storage heating

Heating cables in a layer of thermally conductive material (anhydrite, concrete…). They are easy to install, even in surfaces with a complicated shape. They are particularly suitable for use as main heating systems.

AL MAT heating mats

They are intended to be used under laminate and wooden floating floors installed in what are classified as humid areas – e.g. in bathrooms. They are a variant of ECOFILM heating foils for applications where ECOFILM cannot be used.
