Одним из важнейших этапов монтажа системы heating is the connection of batteries. Technologies for this procedure can be applied different. Very often, experts, for example, use the lower connection of radiators. This technique has its advantages and disadvantages. The bottom connection of radiators, in turn, can also be made in several ways.
Pipe installation during installation of the heating systemperformed most often by the open method. Of course, you can hide highways in the wall. However, this procedure is very time consuming and costly. The pipes that pass right in sight in any case spoil the appearance of the room very much.
The lower connection of radiators allows you to make the highway as inconspicuous as possible. Pipes are laid in this case either at the very bottom of the wall, or even under the floor.
In addition to the possibility to make the interior of the apartment more attractive, the lower laying of pipes also has the following advantages:
the possibility of installing a bottom-flow adapter;
relative ease of installation.
This technology has one more unconditionala plus. The owner of the house is usually not required to additionally purchase a thermostat. On radiators with bottom connection, it is most often already installed initially.
Of course, the lower connection of batteries has not only advantages. This technique has certain disadvantages. These include first of all:
the need for installation on each radiator vent;
less efficient and uniform heating of the premises in comparison with other methods of connection.
Heat loss when using such a connectioncan reach 15%. This, of course, very much. The bottom connection of radiators of heating is used mainly only in systems of forced type. For gravity, this technology is usually not used. It can be used in this case only if there is a special acceleration circuit. That is, when the bottom connection in the gravitational system creates an artificial elevation difference. From the boiler line rises almost to the ceiling. Then it goes down to the window level. Further, the wiring is already on radiators.
In the houses, there are mainly two types of such communication systems: two-pipe and one-pipe. In the first case, passing through the ring, the water returns to the boiler is already cooled. Such systems are used mainly only for small houses or cottages.
In two-pipe circuits 2 rings are mounted.highways. This design allows you to heat the room with greater efficiency. In this case, 2 tubes fit each battery. The bottom connection of radiators is used in both of these schemes.
Входной и выходной патрубок у радиаторов с нижним connection located, respectively, in the lower part. There are also universal batteries on the market. They have four holes for connecting highways. Such radiators can be embedded into the system by any means. Of course, it is allowed to use them for bottom connection.I. The remaining two exits in this case are simply closed with secure plugs.
Sometimes for the lower connection radiators are used, intended for side inserts. However, in this case it is necessary to additionally use a special mounting kit.
Depending on the type of radiators purchased,thus, three basic technologies of their lower connection can be used. Actually, the pipes themselves in this case may be laid directly on the wall, under the radiators themselves, and inside the latter or under the floor. When installing the heating system, radiators are first of all attached to the walls. And only then pipes are brought to them.
Изготавливаться радиаторы с нижним подключением can from different materials. Cast iron models of this type on the market are rare. In most cases, batteries with a bottom connection are made of steel or aluminum. Such models are relatively inexpensive and at the same time have a modern appearance and are reliable. However, bimetallic heating radiators with bottom connection are still the most popular among consumers. Such batteries are made using both aluminum and steel. Actually, that's why they are called bimetallic. Such radiators are more expensive than steel ones. But the price for them is usually less than aluminum.
Steel heating radiators with lowerconnection, as with one-sided or diagonal, have one pretty serious drawback. Over time, they begin to rust. Aluminum models also serve not too long. Moreover, such batteries cannot be used if there is a large amount of impurities in the coolant. Bimetallic radiators are free from such defects.
An efficient heating system in the house will be,Of course, only with the choice of high-quality equipment. This also applies to radiators. Batteries with bottom connection are produced today by almost all companies specializing in the production of such products. In most cases, they deliver models of quite decent quality to the domestic market. But the best customer reviews still earned the battery with the lower connection of brands such as:
"Kermi".
"Rifar".
Batteries of this brand are available. eponymous german company. Their undoubted advantages include excellent build quality and relatively low cost. Radiators heating Kermi with bottom connection equipped with a thermostat. Temperature controllers supplied with thesebatteries are not included. Batteries "Kermi" with the bottom connection are usually used only for insertion into two-pipe systems. You can apply them in one-pipe schemes. However, in this case, the installation is performed using special valves. Marked mclothed with the lower connection "Kermi" as FKV.
Батареи этой марки выпускаются российской by the company. The set of radiators "Rifar", among other things, includes a regulating thermostat. The most popular with consumers are bimetallic batteries of this brand. To the pluses radiators heating "Rifar" with bottom connection include the ease of installation. Install models uThat brand, if necessary, is possible without the involvement of specialists - independently Batteries with the bottom connection "Riffar" are labeled as Ventil.
Radiators are attached to the wall, includingbottom connection, usually on brackets. It uses the construction level. Batteries are hung on the walls with the bottom connection most often with a slight slope. towards the return line. This method of installation allows more efficiently remove air bubbles from the system. But you can fix the radiators on the wall and strictly horizontally.
In this case, you should focus onrecommendations of the battery manufacturer itself. Most often, companies that produce such equipment, advised to install it with a slope of 3-4 mm. In this way, in most cases, aluminum heating radiators with bottom connection are installed. Models of this type are very sensitive to the presence of air in the coolant. Reacting with it, aluminum begins to oxidize rapidly.
The batteries, including those with lower connection, should be positioned correctly. Standards in this case should be respected such:
From the floor, the radiator must be at a distance of not less than 10-12 cm. This will ensure free cleaning of the room, as well as the most efficient heat exchange.
The distance from the battery to the window sill should not be less than 8-10 cm. Otherwise, it will not be possible to obtain the optimal heat flux.
From the wall, the radiator must be at least 2 cm apart. Otherwise, some of the heat from it will be spent on heating the wall, and not the room.
In the radiators "Kermi" and "Rifar" with the lower connection, the inlet and outlet openings are located on one side. Hot water in this case is in the rightmost section. The cooled water leaves through the second section. Branch pipes of such radiators are located vertically - towards the floor. Do universal batteries usually found by both of their edges below. The pipes are located in this case. horizontally.
If the inset of the universal heating radiator is made into a one-pipe system, a bypass is additionally used. On both sides of each battery, taps are installed.-American They are mounted on horizontal pipes. When they overlap the water begins to go through the bypass pipe. This allows Replace or repair the battery if necessary without shutting down the entire system.
In the universal radiator in One of the upper exits is also mounted by Mayevsky's crane. The remaining hole is closed with a plug.
Batteries with bottom connection just crash intosystem using sgonok. Bypass is not applicable. The lower connection of heating radiators in a two-pipe system in this case implies, among other things, the use of a valve. The latter joins the stream. The same scheme is applied when inserting into the two-pipe system of universal batteries. In the one-pipe system, as already mentioned, when using radiators with bottom connection, special fittings are used.
At the final stage, the entire system is crimped in any case. At the same time, the air is vented through the Mayevsky valve. If leakage is detected, corrective work is carried out.
