Underfloor heating in cold winter

Vitaly Lvov from all types of heating floor heating provides the most beneficial impact on human health. This principle of heating was first used back in the V century BC the construction of Roman baths. But the use of cable heating systems and heating systems is relevant not only for the premises. System "warm floor" known almost as much as there is heating at all. One of the first mentions concerns of warm floors in the ancient Roman term (baths), where the heated air is passed through special channels in the stone floor. There were warm floors of similar design and Turkish baths, and there they were required attribute. Thus, humanity is already more than two thousand years (according to other reports, five) appreciates the remarkable comfort, which are systems like "hot sex". However, until the early twentieth century coolant is extremely hot air, which is under the influence of natural draft passed through the floor, gradually giving its heat to the granite slabs. In the early twentieth century with the advent of pump appeared heated floors with heated water. And finally, from the middle of the century with the advent of relatively cheap and affordable energy system began to spread with the use of heating cables. Particularly, they were widely distributed in the last 10-15 years. Should indicate the zone most of the spread of warm floors. Today it is the Nordic countries - Finland, Sweden, Norway, Denmark, where a large proportion of heating of buildings accounts for the system "warm floor". According to various sources, this percentage ranges from 15 to 50%. Interestingly, the very rapid spread of these systems in countries with a fairly warm climate - Spain, France, Latin America and the Middle East. This is due to the fact that the heating season in these latitudes is very short, while the lowest temperature often drops below +3 - +5 ° C. Since the capital cost of the device "warm floor" is very low, and they do not occupy much space, these systems are spread wider and wider. Noticed that the rule: what proportion of the country's power electricity produced from renewable sources (nuclear and hydro), so is the share of electrical heating. Russia, of course, is an exception to the rule. Even 15 years ago, the system "warm floor" as consumer goods were completely unknown. Today the apartment can not be considered not only the elite, and even the average, if there is no "warm floor" in a bathroom or kitchen, and even in all rooms. Types of underfloor heating there are two types of underfloor heating: using hot water pipe (Metafields) heating and electrical cables. Also, the heating system may be of direct action or storage. When the device heating system of direct action is used less potent than in accumulating heating systems, cable. This system allows you to heat the floor surface is faster than the system of accumulation. The system of accumulating heat is used for storing heat generated by cable, with the possibility of using a reduced tariff for electricity during certain hours. Of what did the "warm floor"? Here are his constituents - the heating cable, good insulation, a smart thermostat and concrete screed with floor coverings. These materials are integrated into the system "warm floor" will bring additional comfort in your home. Unlike other devices, heating (central hot water heating radiators, convectors, fan heaters, oil heaters) that lie parallel to the walls, floor heating warms the air from below. The room temperature at the surface of the floor will be the maximum (recommended range of 22-24 ° C). Lifting up the warm air is gradually cooled and at a height of 1,5-2 m has an optimal temperature of 20 ° C. The entire room is heated uniformly, while the conventional radiators provide only a limited area of ??the heat around. It turns out that near these temperatures - too low. In addition, some models of domestic heaters have an open spiral, due to which the room reduced the oxygen content in the air and there is a characteristic unpleasant smell. Such devices are not just ineffective, but dangerous, because careless handling can cause burns and even cause a fire. That's why these heaters can not be installed, for example, in bathrooms, where possible contact with water will result in the best case for the simple failure of the device, at worst - with serious consequences. Of course, there is more safety equipment, but these models provide only heating the local area of ??the room. Perhaps, for heating a room area of ??9 sq. m. will be only a small heater. But if this room - children, then the benefits of such a system is doubtful: the coldest air will be near the floor, as if to place the device next to the play-schim child, then it becomes too hot (a co-sedstvo also unsafe). When it comes to uniform heating, especially large areas, underfloor heating can solve this problem with maximum effect. The data of the heating system does not require additional space for its location, which saves space heaters take up some space. System "warm floor" includes three key elements - heating cable, temperature control and temperature sensor. Its principle of operation is: cable is laid under the floor, and the temperature of its heat is constantly monitored and adjusted (automatically or manually). The heating cable is the main and most important part of the design, so its safety and reliability of special requirements. If any damage to the ka-whitening is difficult to diagnose because it is under the screed thickness of 3-5 cm for access to the cable floor will have to "open". Now the system "warm floor" offered on the Russian market, involving various types of heating cables, each of which has its own scope and specific characteristics. Are commonly used resistive cables with constant resistivity over the entire length, they are solid and two-core. The last few expensive, but they're easier to mount, so they are most often used in the regeneration of warm floors in the living room. Solid suitable for heating a roof, open platforms and ladders. Disadvantages underfloor main disadvantage - the inability to control the temperature. It may also happen that the pressure in the overall system is not enough to bleed your pipes. In addition, there is a real danger of damage to the plumbing industry and a few minutes to flood the downstairs neighbor. And if an accident happens during the operation Metafields (which happens mostly because of deterioration of pipe joints with a riser), will cover the entire tower. Therefore, experts recommend using a water floor where there is an autonomous heating system, - in country cottages. Electric floor - electric heating system can be installed in any location and used at any time, regardless of whether there is heat in the apartment or not. Floor temperature can be adjusted - for this is the thermostat. Eliminates the possibility of programming the system from useless work, and owners - from wasting electricity. In addition, the current device provides security in case of any network failures. Among the disadvantages of such an installation specialists distinguish that it, unlike the steam-heating rapidly heats the floor and this leads to deformation of the floor (plus the astronomical electricity bills).
