Within the electric radiant floor systems that are commercialized in the market, there are different technologies that differ from each other due to their technical characteristics and their operation. In this article we will explain what types of electric underfloor heating exist and we will focus on describing the operation and applications of the underfloor heating in particular.
There are several systems that we can consider as electric underfloor heating:
Cable floor heating and radiant mesh
It is a twisted cable in the form of a coil that is installed continuously in a room, so that any breaking point that occurs would affect the entire installation. In this type of system, the emitter has the diameter of a pen and it is a product that requires very high temperatures to heat the room.
Electric underfloor heating
He heating film, Unlike cable and radiant mesh, is made up of a system of independent sheets that are distributed throughout the rooms and are numbered according to the distribution plan. Each sheet is installed independently from one another, so that, in the event of a specific failure of one of these sheets, the rest of the system does not stop working.
The radiant foil has standard measurements with a width of 550 cm (or 445 cm, depending on the installation), with a length according to needs, it is a heating system that works at low temperaturesto. The advantages of operating at a low temperature compared to the cable or the radiant mesh are, on the one hand, that it is a system of low consumption and on the other, that it can be used with laminated wooden floors since it emits a soft heat that does not affect the wood at all. For this reason, most of the laminate floors that are currently on the market are suitable for the installation of the radiant foil heating system.
100-year functional guarantee: a fail-safe system
Due to its composition, the radiant foil has two conductors in parallel through which the electricity is fed. The heating element consists of 8-millimeter-thick graphite rods. For safety, every 8 millimeters of heating have 3 mm neutral bands. and so on, not giving continuity between one band and another. This means that, if a point of the underfloor heating were perforated, only 8 millimeters of sheet would "die". Not only is each plate independent, but within the plate itself, each circuit is independent.
On the other hand, the radiant folio has a certified useful life by Avis Technique -certification granted by the French CSTB institute and which measures the longevity of products- of 850,000 hours of use, about 100 years.
