Single and strong heating mat
Electric warm floors have moved from luxury to necessity, not only due to a wide range of different manufacturers, but also due to very affordable prices, as well as the ability to quickly solve the problems associated with heating various residential and not only premises. Choosing the one or A different heating system directly depends on the type of future flooring and the stage of repair work. In the case of laying ceramic tiles and porcelain tiles, it is recommended to give preference to cable electric floor heating. It is in turn produced in the form of a heating section, requiring the presence of a screed from above in the area of 3-5 cm and a heating mat that mounts directly directly under the tile. Most often the preference is given to the second type of underfloor heating, as the heating mat requires less preparation work and has a simpler installation in comparison with the heating section,and also allows you to put the system into operation as soon as possible.The heating mat is a shielded heating cable, in a triple insulation, fixed with a fixed step of laying (usually 7-7.5 cm) in the form of a snake on a special rigid grid serpian. The grid is cut, which allows you to lay this type of warm floor in any room, even of irregular shape. According to its type, the heating mat is divided into two types: - single-core, is single-core shielded heating cable, with two cold ends separated from the heating part of the coupling. The power of this system is on average about 150 W / sq. m. This type of warm floor is recommended to choosewhen a comfortable floor heating is required; - strong, is a two-core shielded heating cable, with one cold end separated from the heating part by a coupling. This type of heating has an average power of about 160 W / sq. m. Used when it is necessary to significantly raise the temperature in the room. Cold ends are required for direct installation to the thermostat. Their length depends on the quadrature of the heating mat, on average it is 1.5-3 meters, depending on the manufacturer. If necessary, they are shortened or lengthened to the desired size. The additional shield of the heating cable protects against current shock in case of direct damage. Not all manufacturers are shielded cable manufacturers, as this requires additional costs. It is not recommended to purchase cable heat-insulated floors that do not have these characteristics, whatever the attractive price. Due to the triple insulation and the shielded screen, the heating mats are not afraid of a wet environment, and they can work even in water, in case of unforeseen situations.In addition, another protective function is the presence of grounding.A resistive cable must be used to produce the heating mat and section. Its feature is that ohmic resistance varies depending on the ambient temperature. Factory kits are not subject to increase or decrease, it threatens with the failure of the entire heating system. But it is precisely thanks to the resistive cable that the service life of underfloor floors produced on its basis is much higher. When choosing a manufacturer's company, one should pay attention to the mains voltage required for the proper functioning of the underfloor heating. Many European and American brands produce warm floors, designed for a network voltage of 230 volts. If the network has a lower voltage, the heating system will not work as the manufacturer intended.it simply will not have enough power. When using a heating mat as the sole and main source of heating, the heated floor should occupy about 70% of the total space of the room. If the floors are installed as additional heating, they should occupy about 40-50% of the total area of the room. Installation is allowed only on a free area not occupied with cabinet furniture and household appliances. Be sure to give indentation from all walls and large furniture about 10-15 cm. For safe installation of ceramic tiles, it is recommended to “tighten” the heating mat with a thin layer of tile glue, let it dry and subsequently “lay” the tile in shoes on a soft sole using the usual method , avoiding the formation of the slightest air gaps. The heating mat can only be operated as the tile adhesive is completely dry, usually about 2 weeks.
