We will tell you about some updates in the field of water heating - a pleasant, efficient, beautiful. Are you in the meantime take a look at my old radiators and think: Is not it time to throw them into the dustbin and replaced with new ones. Current radiators - it does not cast those devices, which comfortably dry men's socks. More and more foreign manufacturers to offer us their products. However, as we know, not all that good, that is beautiful and done beyond the borders of our homeland, because the characteristics and conditions for the functioning of domestic central heating system in any of our towns and cities are very different from western ones. In most countries adopted a two-pipe heating system: one tube coolant supply, and on the second play, heaters attached to the system in parallel. In Russia the system of supply has remained one pipe, which involves the installation of large diameter pipes, and this in turn leads to the necessity to use high pressure (from 8 to 12 atmospheres) and temperature (100 ° C). In addition, the coolant (ie hot water) in our systems has increased the number of insoluble particulate matter (oxides of iron, calcium, sand, salt, etc.), clogging pipes and heaters, and spoiling their inner surface. In addition, overseas water heating system is not drained, and corrosion processes are much slower. Another difference between "us" from "them" lies in the fact that the West is the inclusion of the heating system is smoothly through special transmitters, and we at the beginning of the heating season, water is supplied once at full capacity, resulting in a hydraulic "shock" Deplete the "feeble" radiators. The radiator is fun in general, to the heating appliance to function in the central heating system, which has many drawbacks (Incidentally, in the autonomous system used in suburban homes, these problems do not exist), it must possess certain qualities. Cast iron radiators that are resistant to corrosion and can withstand high pressure, onymi as having the fullest. Well, the fact that the thermal conductivity of cast iron is poor, it weighs preizryadno, and does not look too good, before attention is not paid. The main thing - cheap and functional. Used in the West, bimetal, steel and aluminum radiators have long remained inaccessible to our fellow citizens, because they do not meet specific local conditions. But in recent years leading European companies have taken steps to adapt its products to the Russian reality and successfully promote them in our market. Main advantages of steel Korado, Purmo, Kermi, Demrad, bimetallic Sira, Global Stile, Rifar, Swing Metal, aluminum Elegance, Calidor Super, Elite, Global Mix, and others - high heat and the possibility of regulation. Of course, they all have both advantages and disadvantages, and about which experts have not yet reached a consensus, because the products are operating in our country recently. Nevertheless, some experts have already developed the recommendations. Thus, steel radiators are not recommended for use in central heating systems, as they usually are designed for pressures up to 10 atmospheres in the case of "water hammer" can swell up to the state in barrels or break. Reliability bimetallic radiators gradually decreases due to corrosion fracture of welded joints. The main disadvantage of aluminum production - poor tolerability of high acidity of the water. However, all these drawbacks are gradually being overcome by producers. For example, the increase in wall thickness of steel radiators to ensure better resistance to high pressure. Disadvantages of bimetallic and aluminum units are eliminated with new coatings that prevent the destruction. However, it should recognize that the ideal vodootopitelnogo instrument that would serve forever, does not exist. Over time, and iron, and cast-iron radiators are deteriorating and need replacement. Nevertheless, the latter has two compelling advantages - a good heat transfer (the best - in aluminum), and modern design. Thus there is no need to hide the unit behind the curtains, decorative grilles, as it did before. And anyway, do not forget that any "masking" the radiator reduces its power. Incidentally, the market now, you can find many beautiful instruments, but before you buy any of them, be sure to consult with experts, whether it is suitable for your heating system. The warm floor Modern heating systems can dispense altogether with no radiator. We will not dwell on the advantages of heating, hidden in the floor - many apartment owners have appreciated it, set in their homes electrical floor heating. But as you know, the electricity in our country - not a cheap, and there is hardly a large number of people willing to lay an electric heating cable on large areas. For heating of premises there water floor heating, which allows, according to specialists, reduce energy consumption by 20-40% compared to its electric "brother." Today, the water floor heating is most often set in country houses with autonomous heating, but in reality it can be connected (that is successfully being done) to the central heating system. Immediately make a reservation, fun again, not for the poor (from $ 15 to 60 per square. M). Apart from the fact that you have to get a certain number of permits in different instances, you must instruct all of the professional firm, which not only fulfills all your wishes, but warns against mistakes. Water "invisible" heating invented not today or even yesterday. In the old Soviet-era attempts to create a similar system using the "drowned" in a concrete metal pipes. Idea is good, but the metal quickly rots and pipes out of order. Only with the advent of plastic pipe failed adequately to realize this idea - because polymeric materials are not entirely subject to the processes of corrosion, and the inner surface they are so smooth that it does not form any deposits (metal is gradually overgrown with all sorts of salts). Since the pipes in the system "warm floor", as a rule, completely and forever hidden in a layer of concrete, this property determines the efficiency of the entire system. Moreover, the problems of leakage, often occurring in the joints of pipes, too, does not arise, because the device "warm floor" is used, solid, without connections, pipe. Leaks will not be because the floor of one room created a number of separate units (their number depends on the area), independently connected to the central heating system at home. Say, for rooms of 100 square meters. meters installed five units: the solid metal-pipe 100 m long section covers the floor in 20 sq. km. m. To connect to a central heating system should set up the site, and mix with the pump. Mix with a node is required in order to regulate and stabilize the temperature of the water, because in the central heating system, it reaches 100 ° C, while for "hot sex" should be considerably less.
