Warm floor

Summer ... Waiting for him, waiting, as it is - smack, and slipped four, well five weeks, interspersed with rain and wind. Tired. Tropics it is time to make a single apartment. You certainly have heard of heating system, located directly beneath the floor. You bet! The entire northern Europe is already 10 years enjoying this invention. We have these very warm floors are available, for example, in the expensive fitness centers or in steep kindergartens and schools. In Kharkov and Kiev this method has long been heated by the underground. Summer ... Waiting for him, waiting, as it is - smack, and slipped four, well five weeks, interspersed with rain and wind. Tired. Tropics it is time to make a single apartment. You certainly have heard of heating system, located directly beneath the floor. You bet! The entire northern Europe is already 10 years enjoying this invention. We have these very warm floors are available, for example, in the expensive fitness centers or in steep kindergartens and schools. In Kharkov and Kiev this method has long been heated by the underground. So do not think that a warm floor can afford only millionaire. We just recently and the car was a luxury, and a mobile phone in rarity. Where else but in Russia it is best cold take hold, this new warm? Now warm floors are used in cafes, hairdressers and fitness clubs located in basements or on ground floors of buildings. The "personal use", of course, such heating is more common in suburban homes. But more and more owners of city apartments decide to get rid of drafts and warm slippers, now and forever. Warm floor logical thing to do in the hallway, kitchen, bathroom and toilet, where lies or may lie with ceramic tiles. Producers argue that the warm floor can be done under the linoleum, parquet, carpet and boards. Perhaps we should insulate the floor in his bedroom or in the nursery, so there kids could safely crawl. In short, the appetite comes with eating. So: the heated air is lighter than cold air, rises. It turns out that the floor surface air is heated, rises to the ceiling, and the cooler, of course, falls, and again heated. This cycle, nature's own scheme. Specialists insist that the proper installation and operation of underfloor heating operates without interruption for 15 years. Manufacturing companies offer a guarantee of 16 years. In our country, technology is a warm floor appeared about 10 years ago, along with the fashion for renovation, and usually only been available to wealthy people. Prices have since fallen, and a lot of offers on the market. Electric floor heating does not need special equipment, as previously thought, and connects to most ordinary home network. The big downside of floor heating is the complexity of its installation. The fact that both options - water and electric - suggest concrete floor, which is mounted heaters equipment. Screed, in turn, dries for about 30 days, and only then it is possible to put any coating. Therefore, it's best to do this work under construction or repair. Plays an important role insulation, which is needed not only on the first floor. It makes no sense to heat the ground and the ceiling of the neighbors. Checked that no insulation from the cable goes down 30% of the heat and up - 70%. According to specialists, insulation (foil and laminated penopropilen, penofil, Izoflex, cork boards) change the ratio to 15% and 85%. The temperature at the surface of the floor 24 degrees, at head height - 20. The location of the heating system in your hands: if from the great-grandmother went to the huge closets and dressers, then heat the floor beneath them is not worth it. While there are two types of warm floors - water and electric. Each manufacturer claims that his system is better, and, of course, criticizing competitors. Let's listen to their mutual claims. Electric heating option Argued that the electromagnetic radiation are dangerous to infarktnikov and proshuntirovannyh. Surely, a certain number of radiation coming from the floor. But experts say that they are much smaller than on TV. Given the time of our ubiquitous interactions with electrical appliances, believe me, it's a small load on the body. In many towns and villages in Russia or impossible to use central heating, or the quality does not meet consumer needs. In other words, there is simply turned off the heat. Heated becomes the only solution. When installing the heating cable heating cable system on a wooden base (lag) and the insulation under the flooring should be used very carefully, because wood conducts heat poorly and may overheat the floor. In this case, try to avoid contact heating cables with the wooden parts - parquet and lags. Cable is usually mounted on a metal grid suspended from the parquet at a distance of not less than 2 cm Route the cables in parallel lag and at intersections with them necessarily insulate the foil. Warm Math With electric heating option, in addition to cable, there is another option: some manufacturers are working with the material - polymer mats with a given step cabling. This heating mat is rolled out directly on site. It is at this stage and need to determine the location of furniture, avoiding those places which can not be heated. Weather foundation of the house Once the cable and thermal sensors are placed, secured and power sum up this entire design is filled screed height of 3-5 cm (in this case, if the top is glazed or ceramic tile, linoleum, carpet materials). If the top is laid parquet or supposed reconstruction of the old floor screeds make less - up to 2 cm in this case, there are limitations on the power - for flooring, it should not exceed 80-100 W/m2, and laminate flooring should not be heated above 26 degrees. Generally, flooring is good to pre-dried to 4-6% moisture content. When you are ready, we must muster patience-of - the heating cable can be switched after complete solidification of ties, and this, as we have said, 30 days. There are other rules that must be observed: • heating mat should not be subjected to mechanical stress, it is forbidden to shorten and lengthen; • must be thoroughly cleaned of debris and sharp objects base on which the heating mat is laid; • require the utmost attention and care not to damage the heating cable during laying; • the cable should be grounded in accordance with the applicable rules of PES and SNIP; • forbidden to lay electrical heating at temperatures below -5 ° C. And the last tip. Be sure to make a drawing of the heated area, detailing the location of heating mats, end and couplings, temperature sensor and places connected to the mains. When the heating cable is damaged during installation or during construction, this scheme will help to quickly find the location of the damage. Another nice feature of heating cable - its longevity. For example, native plant "FTAs" in Mytischi provides systems warm floors 16-year warranty. At the same Finnish cable company Tassu 5-year warranty. He is not inferior in quality, but our factory is closer, therefore, problems with warranty repairs is less. Water heating option main argument of opponents of water underfloor heating is as follows: if the pipe burst, instantly spilled boiling water will hurt the lower floors. But the fact that the polymer and metal pipes are not only not broken, but perfectly bend. They can put in whatever form - zigzag, rings, stars, if only the length of one such pattern in the room does not exceed 120 m (pipe diameter 20 mm). The warranty for this kind of technology - 15 years. Good to know that you walk on water. She murmurs, lulls ... However, pipes may unexpectedly and zagudet - pressure difference, can not be helped. In electricity it happens. However, more alarming. If you connect to the CHP or a boiler, it will depend on the schedule of the heating season. This is, to put it mildly, not in the interests of the consumer. But the pipe with hot water specialists connect does not advise. You will calculate and fined, because there is a problem with the water temperature with neighbors. You just need to put an electric heater and a device that provides water circulation. In the case of a water floor heating, the role of the heating element has no electrical cable, a polymer tube with hot water. Used in this system of multi-layered metal-plastic pipes on the order of lighter metal, does not leak air, do not rust and can last up to 50 years and more. Pipes are laid from the reservoir into the floor and back into the system there are no hidden links, which might be formed to flow. From the water supply to install the valves through which ensures the same pressure drop in all the underfloor heating pipes, irrespective of the fact that the pipes in the rooms can have different lengths. Pipe Mounting calls Radiant floor is as follows. Foundation is laid on a flat layer of waterproofing, which is no less important to the plate in contact with the ground. Following is put a layer of insulation. Along the perimeter of the room, along walls, fit damper tape. It can be successfully replaced by strips of thermal insulator. Next begins the layout of pipes with a certain step in the desired configuration, which is called the "spiral", "zigzag" or "snail". All parameters are determined by calculation rather than by eye. "Snail" is the best circuit, which ensures even distribution of heat - the temperature difference at the flow and return pipes are practically invisible. Layout of pipes for heating water flow pattern and their attachment to the insulation boards shall either staples or laying between the projections in special panels of polystyrene, sometimes using special mounting rails. There are many options, but the easiest and, therefore, common when a heat insulator on the entire floor area rolled mesh reinforcement. To it with wire or plastic straps attached tube. In any case the pipe organically incorporated into the design of the floor and must be protected from the slightest mechanical damage. After laying the pipes and connecting pipes to the collectors of the system filled with coolant and pressure testing is carried out - in other words, the hydraulic tests. After that, as in the case of electric floor is poured cement. The pipe should be completely recessed in the concrete and screed over it should be at least 30 mm. Concrete at the same time serves as a screen for the distribution of heat over the floor. You can also include a system only after the concrete mixture hardens. No concrete new technology eliminates the need for concrete - there is a special lightweight floors, which are placed in and fastened the pipe. This setup, of course, much easier (and more expensive) concrete and is used in cases where too much is undesirable to burden the floor. The last character of the coating, but a very important layer structure - coating. Materials and their thickness effect on heat transfer. The criterion is recommended to use the indicators of the thermal resistance R (the higher the figure, the longer it will be heated floor), which are: • Tile and Marble - 0,02 m 2 ° C / W; • for synthetic flooring - 0,075 m2 ° C / W; • parquet and carpeting - 0,10 • 0,15 m 2 ° C / watt. Keep in mind that for a value exceeding 0.15 m2 ° C / W floors will serve as a thermal insulator. The choice is likely, water the floor is suitable for private homes, which already has a boiler. If not, then it can deliver. Even better, if the house has gas and AGW, then water the floor just cries out there. In a typical apartment with him will be too many complications. If the rearrangement of the towel warmer or radiator is required to obtain permission is not one instance that is there to say about water heating floor (see comment lawyer). How much to expect? Pricing policies of all firms, establishing warm floors, not very uneven. Combines the general criterion: the greater the area of ??customer orders, the greater the discount he gets. For example, warm electric under floor screed is worth on average $ 100 per 1 m2, Tile - $ 120, but if the order goes to the 35 meters at once, it would cost 300-400 conventional units. Water sex typically costs between $ 30-35 for mounting 1 m2, but many firms are taking up an area of ??100 m2. Then the price of one square meter, for example, in Dvadtsatimetrovy room, depending on the complexity of the work, approaching $ 1000. Money, of course, considerable, but we must remember that during operation water half compared with the electric cost much less. Obviously, at some time in our country will build a home with warm floors. Cable systems are slowly but surely create a serious competition to the traditional form of heating. Uniform heating of the room where there are not too hot or too cold zones - is what is needed for Russia. A person does not matter what kind of floor heating will be more cost-effective in commercial construction. If only the house was warm. Beware of traffic jams! But we must warn you that if in the case of the electric floor, you can only suffer from electricity blackouts and banal drop caps, the water-floor trifled with. At the slightest inaccuracy in the installation or not a flat surface carrying the sex, the coil sections may be convex. In these places will arise airlocks. They dramatically increase the hydraulic resistance of the circuit and reduce the heat transfer tubes in these zones. Tube can cause a complete stop the flow in the coil, if there is a circuit pressure drop will exceed the disposable head. We are all familiar with this phenomenon on the example of radiators - many homes they "purged" before the beginning of the heating season. Comment lawyer Eugene Pinnacles, Consulting Center Norman Estate device Radiant floor equal to the redevelopment. Therefore, in accordance with the Law of the City of Moscow on September 29, 1999 № 37 "On the order of conversion facilities in residential buildings in the city of Moscow and its amended on 7 April 2004 you will have to go through fire, water and copper pipes. You will need to obtain permission from the executive bodies in accordance with their competence as defined by the Moscow government. You will also need to obtain their written instructions to local authorities - those should give you a conclusion about the possibility of rebuilding the premises claimed. Otherwise, according to the 13th part of the Act and Article 293 of the Civil Code of the Russian Federation, local self-government at the request of an apartment building manager may go to court with claims for sale at public auction premises owned by individuals and legal entities. In this case we are talking about multi-family homes, ie, of a separate room in a house, but if we are talking about a private dwelling, then these issues are resolved at the consultation stage and the approval of the construction project.
