How to connect batteries to central heating. Diagonal connection of a heating radiator: diagram, pros and cons. Useful tips for those who connect heating batteries on their own

Heating batteries can be connected in one of three ways. When choosing, it must be borne in mind that each has its own pros and cons. The pipe layout is the basis for the selection. Diagonal is not used in city apartments, as they usually have a side connection. However, some DIYers and professionals prefer the diagonal option when choosing an effective system.

Features of the diagonal connection diagram

If you also wondered why the diagonal connection is the most effective, then you should consider this option in more detail. If we take into account the process, where hot air or water is involved, then the action will take place according to one physical law, which involves the rise of warm masses upward, while cold ones go down.

To ensure an even distribution of heat throughout the volume of the radiator, the coolant should be distributed over the battery. As mentioned above, side connection in city apartments acts as the main circuit. After all, forced circulation under high pressure is used there. The diameter of the outgoing and outgoing connections is only 20 mm. Through them, water enters the battery under high pressure, which allows you to evenly and quickly fill the device.

If we are talking about private housing construction, where the circulation is natural, the filling of radiators occurs under the influence of the above-mentioned physical law. That is why hot streams penetrate through the upper branch pipe, pushing cold water through the lower outlet from the opposite side. The two nozzles are located diagonally when viewed from the device. Hence the name of the connection. The coolant fills the battery gradually, giving off heat to the entire volume. It is necessary to take into account not only the law of heat transfer, but also the physical law. That is why this scheme is the most effective.

Features of the implementation of the diagonal scheme

You can implement the diagonal connection of the heating radiator yourself. Work should begin with preparing the battery. To do this, you need to take care of the availability:

  • heating devices themselves;
  • shut-off valves;
  • pipes;
  • fittings;
  • other additional devices such as heat meters, a Mayevsky crane and a thermal head.

At the first stage of the work, a radiator is installed. In this case, it is necessary to take into account the rules. This is due to the fact that the efficiency of heat transfer will depend on them. When a diagonal heating radiator is used, part of the window opening must be aligned with the axis of the radiator. To the upper collector from the window sill, it is necessary to maintain a distance of within 15 cm. As for the step from the floor to the lower part of the collector, it should be the same. A distance of 5 cm from the wall to the battery must be set. Errors may occur. If we are talking about the distance to the window sill or the floor, then the error can reach 4 cm, while the step between the battery and the wall can be increased or decreased by 1 cm.

If you decide to use a diagonal connection of a heating radiator, then you must take into account some assumptions that will affect the rate of heat transfer. For example, if there is no window sill in the room, then this indicator can be increased by a maximum of 20%. Moving the battery closer to the floor will reduce heat transfer by 7%. To increase the efficiency of heat dissipation, professionals recommend complementing the radiator with a reflective screen that is installed on the wall. You can use a sheet of fiberboard or cardboard for this, each of which is covered with foil. In this case, the heat transfer can be increased by 25%.

If you want to achieve the correct operation of the radiator, then you should approach the installation and installation with the utmost care. It is important to correctly align the instrument horizontally. You can get rid of distortions using a level. At this stage, it will be important to apply the markings. Once the markings can be applied, the brackets can be installed.

A self-tapping screw is used as a fastener, installed on plastic dowels. On sale today you can find brackets that are shaped like pins. They are screwed into a dowel of impressive diameter. Now everything is ready to install the radiator and connect it to the piping system.

Radiator complete set for diagonal circuit

The diagonal diagram for connecting heating radiators necessarily assumes a complete set of batteries. To do this, it is supplemented with which you can release air. You need to take care of the availability of metal couplings, which are also known as American women. They are installed in the branch pipe, for this you need to use threaded metal couplings. Valves are strengthened to the latter; there should be one such element for each branch pipe. This will cut off the battery from the heating network if you are faced with the need for repair. In this case, the system itself will operate normally.

More information on diagonal wiring

The diagonal connection diagram for heating radiators in city apartments is rarely used. However, according to experts, this technique can be used if the number of sections in one battery exceeds 12 pieces. With a bottom side connection, as well as when circulating water under pressure, the pressure will not be able to overpower such a number of sections. The extreme ones will stay a little warm, and there will be no sense from them.

This scheme is used in a two-pipe wiring system. The falling circuit must be connected to the upper branch pipe, while the return circuit must be connected to the lower one. If the circulation is forced, then the connection can be carried out the other way round, but in this case you will encounter a decrease in efficiency.

For reference

When a diagonal connection of heating radiators is used in a private house, the heat loss through the batteries is 2%. Therefore, when carrying out heat engineering calculations, in this case, a coefficient is taken that is 1.1.

The main types of connection

There is also a one-way connection, in which the hot water supply pipe and the return pipe will be connected on one side of the radiator. The application of this principle is rational for single-storey buildings. The scheme is suitable if you want to connect a long radiator with up to 15. But if this parameter is increased, the heating efficiency will decrease, because the last sections will be colder.

Considering the main options for connecting heating radiators, you should also pay attention to the bottom connection, which is suitable for those systems whose pipes pass under the floor surface. In this case, there will be a small piece of pipe above the surface, leading to the lower branch pipe. The inlet pipe is installed on one side of the battery, while the outlet pipe is on the other. The disadvantage of this method is significant heat loss, which reaches 15%. At the top, the battery may not fully warm up.

Important to remember

A single-pipe diagonal connection of heating radiators is used quite rarely, because such a scheme has a significant drawback, expressed in the absence of the possibility of adjusting the heat supply. Thus, the user will not be able to adjust the degree of heating of the radiators, in some cases this feature is a significant disadvantage. However, heat transfer is calculated even when creating a heating project, and in the future it must correspond to the specified parameters.

Main advantages of diagonal connection

The diagonal method is good because it can provide the highest heat transfer coefficient. This is true when compared with the rest of the above schemes. In other words, in the case of a diagonal connection, you can provide the room with the maximum amount of heat. The diagonal connection of heating radiators in the apartment should ensure the movement of the coolant inside the battery with the formation of a gradient circuit.

The effectiveness of this scheme may decrease, which will happen with a large number of sections. But even in this case, the maximum number of them can be 24, while in the lateral scheme this parameter is only 12. This feature can be considered an important advantage, because you can use longer radiators. With a side connection, an increase in the number of sections will be accompanied by a less efficient operation of the elements located on the sides.

Main disadvantages

Diagonal connection of heating radiators, the pros and cons of which are described in the article, can also be used by you. An important disadvantage of this scheme is the not very attractive design. After all, one cannot argue with the fact that the additional pipe does not look very aesthetically pleasing. It connects the return pipe and the upper radiator hose, the first of which runs from the bottom. The downside is that not all city apartments have the ability to provide this type of connection. Indeed, during the construction of Soviet high-rise buildings, they strove for the minimum consumption of materials, and often did not install a separate bypass.

Conclusion

Diagonal connection of a heating radiator with a one-pipe system, although undesirable, is still possible. But at the same time, you should take into account that in order to increase the level of heat transfer, it is important to take into account the increasing coefficient, which sometimes reaches 1.2. Thus, the passport heat transfer must be increased by 20%.

Arrangement of a heating system (hereinafter referred to as CO) in a separate apartment or in a private house is carried out by connecting heating radiators to the mains supplying hot water coolant from an external heat source. In the designs of standard cast iron, bimetallic or aluminum batteries, threaded sockets are provided at the ends of each section for assembly connections to each other or for connecting pipelines for supplying and removing the coolant. The illustration shows a traditional cast iron radiator with plugged top and bottom end sockets.

Cast iron heating radiator

To properly ensure the tightness of the connection of the steel or polymer pipe of the thermal wiring to the battery, welding and threaded connections are used. The photo shows an element of a section of a cast-iron radiator with a sleeve for a threaded connection.

Coolant circulation through radiators

Heating of the room in which the heating radiator is installed is carried out according to the following principle:

  • the water heat carrier heated to the required temperature is supplied through a one-pipe or two-pipe system of pipelines to one of the end sockets of the radiator, intended for the inlet of hot liquid in accordance with the selected scheme for connecting heating radiators in this house or apartment;
  • the coolant supplied to the input of the heating battery circulates through all its sections, giving off the brought heat to the material of the radiator walls;
  • the walls of the radiator heated from the inside emit heat from the outer surface into the surrounding environment, thereby heating the room;
  • the coolant, which has completely cooled down inside the radiator when passing through its sections, leaves the battery through the upper or lower end socket, designed by the selected connection scheme for the cold coolant outlet;
  • The cooled water that has left the radiator is directed through the outlet pipeline (commonly called the "return") to the heat source for subsequent heating and passing through the next circle of circulation.

The presence of four input / output sockets at the ends of the mounted battery (two on each of the opposite sides) predetermined the existence of several options for the movement of hot water inside the radiator, depending on how they are connected. With any scheme of liquid circulation inside the volume of batteries assembled from 6-8-12 and more sections, an uneven distribution of heat fluxes is noted both along the height and along the battery. The figure shows a thermogram of a cast iron radiator at bottom flow. The spread of temperatures along the height or along the length can reach 10 degrees.

Thermogram of a cast-iron radiator at bottom flow

In reality, the temperature spread is much larger, since scale and lime deposits settling in the lower cavities of the sections prevent the passage of hot water at the bottom of the radiator. The hot coolant immediately rushes along the free upper ducts to the exit, without even washing the distant sections. In fact, the temperature of such clogged, remote from the entrance of the sectional sections can reach only 25-30 degrees.

The efficiency of each heating device separately and of the entire heating system of the house depends on the heating radiator connection scheme, which sets the route of the coolant movement inside the assembled sections and affects the intensity of hot water circulation when it is washed by the inner surfaces of the sections.

Heating agent supply systems

The organization of heating in a private or apartment building is carried out by installing one-pipe or two-pipe systems for circulating a water coolant.

One-pipe heating circuit

In the one-pipe version of the heating system of the house, the water coolant is supplied in series to the connected sectional batteries. This option eliminates the division of the main heating main into circuits for supplying hot water and returning cooled water. A closed one-pipe circuit encircles the entire house along the corresponding trajectory of the heating main. The figure shows a schematic diagram of a one-pipe heating option for a two-story house.

Schematic diagram of a one-pipe CO of a two-story house

The circuit works as follows:

  • hot water coolant comes from a heat source (in this case, a boiler, in other cases, a central heating main) through a pipeline (red lines in the diagram) to sectional radiators;
  • red arrows mark the branches of the movement of hot water supply to each battery separately;
  • in batteries, the hot liquid gives up the brought heat to the walls of the battery sections and leaves the radiator, already cooled;
  • blue arrows show the movement of cold moisture along the outlet branches of the pipelines towards the vertical section of the pipeline that returns the coolant to the main heating main;
  • cold water comes to a centrifugal pump (or pumping group) to repeat the circulation.

Serial connection of heating devices dooms radiators to unequal temperature of heating batteries not only on all floors of the building, but also in each apartment, since the coolant gradually loses its originally obtained temperature as it passes through each point of heat consumption.

Two-pipe heating circuit

In a two-pipe heating system, two independent pipe branches are used:

Schematic diagram of a two-pipe heating system

  • hot coolant is supplied through one pipeline (red line);
  • the cooled coolant is received through the other pipeline (blue line).

This scheme ensures an even distribution of the hot coolant at all points of heat consumption. The main advantage of a two-pipe heating heating main over a one-pipe scheme is:

  • the ability to control and adjust the temperature regime in each separate room;
  • the ability to repair each heater without stopping the entire CO.

When comparing heating systems, one should take into account the fact that for a two-pipe system there is no need to supply hot water at high inlet pressure. In a single-pipe CO, for uniform heating of radiators along the entire circuit, high pressure has to be injected, which leads to emergency leaks in the network and equipment wear.

Heating water supply to radiators

It is impossible to work out an unambiguous criterion that determines how to correctly connect the battery to a heating main with hot water. Manufacturers of heating radiators have filled the market with devices with different layouts of inlet sockets for the supply and outlet of the coolant. Architectural planning considerations contribute to the motivation for choosing the method of installing batteries and connecting them to the riser.

In many cases, the concept of "connecting the batteries correctly" means hiding all pipeline communications in the floor or in the walls as much as possible, without delving too much into which method - diagonal or other method - you will have to connect. Models are available that allow you to connect pipes not only from the sides, but even from the bottom, using compactly located nozzles (in modern products, the distance between them is only 50 mm).

The only criterion that allows you to objectively assess the effectiveness of the connection according to the selected scheme is the ambient temperature in the room. A comfortable microclimate in a house or apartment directly depends on how correctly the number of sections of each heating device is determined, and on their heat transfer, the level of which can be varied by the method of installing wiring pipelines with batteries.

The connection of radiators to the heating main is carried out according to several schemes, among which the most common are:

Diagrams for connecting heating radiators to the main network

  • pos. (a) - lateral one-way connection;
  • pos. (b) - diagonal connection;
  • pos. (c) - lower versatile;
  • pos. (d) - bottom connection, the figure shows the options for connecting to one-pipe and two-pipe CO.

On the diagrams, red lines and arrows show the movement of the hot coolant, blue lines and arrows show the direction of the cold (cooled) coolant.

Features of connection diagrams

  1. The lateral one-sided arrangement of the inlet and outlet of the coolant is popular in high-rise apartments as the most convenient for installation with the accepted vertical passage of heating risers. The best heat transfer is achieved when hot water is supplied to the upper branch pipe and the cooled liquid is removed from the lower branch pipe (item a in the figure).

The heat transfer parameters for lateral decoupling are taken as a basic standard when compared with other schemes (diagonal, bottom and their variations). The heat transfer of the circuit (a) is taken as 100%. In addition, when calculating the power of heating devices, a correction factor is introduced that increases or decreases the calculated indicators. For radiators with side connection, we agreed to take K = 1.0. For diagonal connections K = 1.1-1.2, for bottom connections, the coefficient varies from 0.7 to 0.9.

When hot water is supplied to the lower branch pipe, heat transfer decreases from 5 to 10%.

  1. A correctly connected diagonal connection assumes hot liquid supply to the upper branch pipe on one side of the battery and cold water drainage from the lower opposite (diagonal) connection (item (b) in the figure). The circuit is most effective in multi-section batteries, its heat transfer is equated to 102% of the same parameter of the reference side decoupling. Diagonal connection better than other schemes provides an even distribution of heat over the radiator area.
  2. The lower versatile connection is realized by the supply and return connections in the opposite lower end pipes of the radiators (item (c) in the figure). Compared to the lateral circuit, the heat loss is 20-25%. But this scheme suits many owners due to the possibility of connections with trunk pipes hidden under the floor. Most often used in private buildings.
  3. The bottom connection through adjacent pipes is similar in terms of indicators to the previous scheme. Its use is due to architectural considerations, when all communications are recessed in a concrete floor screed or under a raised floor.

Video about circuits

The options for connecting heating radiators are discussed in the video below.

Understanding the features of various ways of connecting the heating main to heating devices will make it possible to most effectively use every square centimeter of the heat transfer surface of a heating radiator.

The battery heats up poorly due to an error in the choice of the wiring diagram

Otherwise, instead of a heater, the owners will receive an ordinary piece of furniture, and they themselves will freeze all winter. The figure shows the heat distribution in a battery with an incorrectly selected connection option.

Connection example

Providing a house or apartment with heat is the number one task in the cold season. Therefore, every man in the street strives first of all to create an efficiently working system, which would be economically justified at the same time. And since most of the heating systems are of the radiator type, the question of how to properly connect the heating batteries is one of the most relevant.

For many, this does not mean anything, especially for those who first encounter the problem of piping a heating system. But those who have already dealt with the creation of such schemes, perfectly understands what is at stake.

There are not so many classifications of types of piping and piping, especially when it comes to piping radiators. Therefore, it will not be very difficult to understand this issue. Most often, it is the piping that affects the nature of the connection of battery radiators. Therefore, it is necessary to consider the classification of various heating systems and establish which one is best suited for this or that connection.

Heating system classification

The main criterion for dividing heating systems is the number of circuits. On this basis, all heating systems are divided into two groups:

  1. One-pipe.
  2. Two-pipe.

The first option is the simplest and cheapest. This is, in fact, a ring from boiler to boiler, where heating radiators are installed in between. If it comes to a one-story building, then this is a justified option in which the natural circulation of the coolant can be used. But in order for the temperature to be uniform in all rooms of the house, it is necessary to provide for some measures. For example, build up sections on the extreme heatsinks in the chain.

The best option for such a pipe scheme is to connect the battery using the Leningrad method. In fact, it turns out that an ordinary pipe runs through all the rooms near the floor, and radiator batteries cut into it. In this case, the so-called bottom frame is used. That is, the radiator is connected to the pipe through two lower nozzles - the coolant enters one and exits the other.

Attention! Heat loss with this type of battery connection is 12-13%. This is the highest level of heat loss. So before making such a decision, weigh the pros and cons. Initial savings can turn into high operating costs.

Permissible errors

In general, this is a good wiring diagram that pays off in small buildings. And in order to evenly distribute the coolant over all radiators, you can install a circulation pump in it. The investment is inexpensive, and the device works perfectly and requires little power consumption. On the other hand, an even distribution of heat throughout all rooms is ensured.

By the way, the one-pipe piping scheme is very often used in city apartments. True, the bottom battery connection cannot be used here. The same should be said for the two-pipe system.

Other types of connection

There are more profitable options than the bottom connection, which provide a decrease in heat loss:

Diagonal view

  1. Diagonal. All experts have long come to the conclusion that this type of connection is ideal, regardless of which piping scheme it is used in. The only system where it is not possible to use this type is the horizontal lower one-pipe system. That is, the same Leningrad woman. What is the essence of the diagonal connection? The coolant moves diagonally inside the radiator - from the upper branch pipe to the lower one. It turns out that hot water is evenly distributed throughout the entire internal volume of the device, descending from top to bottom, that is, in a natural way. And since the speed of water movement is not very high during natural circulation, then the heat transfer will be high. Heat loss in this case is only 2%.
  2. Lateral, or one-sided. This type is very often used in apartment buildings. The connection is made to the side connections on one side. Experts believe that this type is one of the most effective, but only if the circulation of the coolant under pressure is installed in the system. In city apartments, this is not a problem. And to provide it in a private house, you will have to install a circulation pump.

What is the advantage of one species over others? In fact, the correct connection is the key to effective heat transfer and reduced heat loss. But in order to properly connect the battery, you need to prioritize.

Take, for example, a two-story private house. What to prefer in this case? There are several options here:

Two and one pipe systems

  • Install a side-connected one-pipe system.
  • Install a two-pipe system with a diagonal connection.
  • Use a one-pipe system with lower wiring on the first floor and top wiring on the second.

So you can always find connection diagram options. Of course, you will have to take into account some nuances, for example, the location of the premises, the presence of a basement or attic. But in any case, it is important to correctly distribute the radiators among the rooms, taking into account the number of their sections. That is, the power of the heating system will have to be taken into account without fail even with such a question as the correct connection of radiators.

In a one-story private house, it will not be very difficult to correctly connect the battery, given the length of the heating circuit. If this is a one-pipe Leningrad circuit, then only the bottom connection is possible. If there is a two-pipe scheme, then you can use a collector system or a solar one. Both options are based on the principle of connecting one radiator to two circuits - coolant supply and return. In this case, the top piping is most often used, where the distribution along the contours is carried out in the attic.

By the way, this option is considered optimal both in terms of operation and during the repair process. Each circuit can be disconnected from the system without shutting down the latter. To do this, a shut-off valve is installed at the pipe branch point. Exactly the same is mounted after the radiator on the return pipe. One has only to close both valves to cut off the circuit. After draining the coolant, you can safely engage in repairs. In this case, all other circuits will operate normally.

Classic system

Many people think that the option of connecting a radiator is not so important when it comes to heat dissipation. After all, a lot will depend on the type of heat source chosen. For example, bimetallic heating radiators have a higher heat transfer than cast iron ones. But imagine that cast-iron devices are installed according to the diagonal principle of the movement of the coolant, and bimetallic ones along the bottom. In the first case, heat loss is 2%, and in the second - 12%. The difference in losses is as much as 10%. For a heating system, this is a fairly high indicator that will affect not only the temperature regime inside the premises, but also the amount of fuel consumed. This is very important for private houses.

Today, experts give recommendations on how to increase the heat transfer of devices. To do this, a reflective panel can be installed on the wall behind the radiator, for example, a regular piece of fiberboard trimmed with aluminum foil. But keep in mind that the distance from the wall to the radiator in this case should be at least 1.5 cm.

Conclusion on the topic

What is the conclusion? Correct connection of heating radiators is an important criterion for the effective operation of the entire system. This will affect not only the temperature inside the rooms, but also the fuel consumption. And saving today has become the main indicator on which the well-being of every inhabitant of apartments and private houses depends.

From experts you can hear the opinion that a one-pipe heating system is a relic of the past, nevertheless, it still stands among effective methods of heating private and multi-storey buildings.

One has only to slightly modify the well-deserved classics, and all the advantages of a one-pipe connection will appear when installing heating systems: comfort, coziness in the house and the possibility of local repair of the heating system without turning off the heat supply.

And also - saving money when the power supply of the territory is cut off.

One-pipe system: connection highlights and real installation benefits

Initially, a one-pipe system for connecting heat supply was the only profitable: heating radiators were connected according to physical parameters "Serial connection".

The choice was based on economical pricing:

  • Costs cut in half on the purchase of conductors for the coolant in comparison with a two-pipe system.
  • Savings have been achieved when buying footwear, fittings, taps.
  • Radiators of all existing brands were suitable for this system: from cast iron classics to "advanced" bimetal.

Not without negative points: radiators, sequentially looped, heated unevenly, the latter in the circuit did not correspond to the specified (expected) temperature parameters. This was until the time when experts discovered the bypass principle known as bypass.

Pros of bypass

It is sometimes difficult for a homeowner to make a decision on the recommendation of specialists when installing a one-pipe heating system to install a bypass. The principle is simple: a bypass pipe is included in the design (this is the bypass), which will save material resources, and allows for local repair of the radiator without shutting down the entire system. The latter is relevant for owners of private houses and for residents of typical high-rise buildings of the last century.

Photo 1. Radiator connected to the heating system. Arrows indicate the location of the bypass and ball valves.

For owners of an extensive living space with a one-pipe heating system, it will be advisable connecting a "stroke"... It is a piece of pipe that is installed in the immediate vicinity of the radiator. Pipe diameter one position lower than the cross-section of the main pipeline... This is due to the fact that when the carrier is fed, the water prefers to rush through the channels of a larger diameter. Thus, it becomes possible to start repairing leaking radiator assemblies painlessly for heating a house.

The gravity system does not provide a comfortable (and adjustable) temperature in living quarters, this is where a bypass is needed. Craftsmen mount a bypass pipe with a circulating pump and temperature sensors located in it. It doesn't matter if the power supply is interrupted - bypass will direct water flows according to the principle of "gravity" and in emergency mode. Bypass pipe brings savings to the homeowner up to 25% electricity charges, alternating between gravity and forced circulation of the coolant.

Attention! Install the circulation pump in the bypass pipe, adhering to the "curvilinear" rule: the more bends, the lower the thermal conductivity of the heating system.

The bypass is “surrounded” on both sides by ball valves to block the water supply to a specific radiator.

Correct installation of the structure without a bypass pipe

Such a scheme does not require a parallel pipe branch. based on welding or fastening using adapters and fittings.

The primitivism of installation and some cost savings will subsequently bring a lot of problems to the homeowner. The most expensive item is shutting down the system in case of local leaks in the pipeline or radiator.

Instruments

To organize heat supply, you do not need to purchase special sets of tools - plumbing fixtures and those keys that are available from the home master will cope with the task. Add only specific tools to the home kit:

  • special keys for connecting American women;
  • tools for screwing adapters;
  • torque wrenches for delicate parts.

Reference. Professionals advise not to purchase expensive equipment for attaching parts with a union nut. Copes with the task open-end (or adjustable) wrench with pliers. The first one holds, the other twists.

Schemes and connection methods

With a one-pipe connection diagram of heat supply in housing several schemes for obtaining energy from a heat source are used.

  • Diagonal connection is an effective method. The pipes alternate with the upper and lower connections at the border of one radiator: the heat input falls on the upper pipe, the output is at the bottom of the battery. Such a system has proven itself perfectly when connecting radiators. over 10 links, the batteries are warmed up evenly.

Photo 2. Connecting a heating radiator diagonally. The hot coolant is marked in red, the cold one - in blue.

  • The lower piping, according to experts, is less efficient in terms of thermal conductivity, but it is used in closed heating systems when pipes run horizontally from the boiler and are hidden under the floor.
  • Vertical connection based on the installation of a riser in the boiler area, the remaining elements of the heating structure are connected to it. The advantage of this method is the absence of air congestion during the gravity of water.
  • Top routing(incoming and outgoing pipes are installed at the top from different sides) is used in radiators of a special design, where forward flow is excluded. The media goes down the first section and runs along the rest of the links.

How to properly connect radiators

When installing the heating system, it is important to correctly install the radiators, fixing them on the wall under the window openings. According to the norms, it is impossible that the distance from the floor and window to the battery was less than 10 centimeters... The gap from the wall is half the allowed.

To secure these elements use 3 brackets for each unit: two are attached at the top points, one at the bottom.

Level the surface of the battery vertically; horizontally, a slight decrease is allowed so that air does not accumulate in the upper part.

Achieve such a level that the radiator plugs come directly to the location of the pipes. Screw on each battery Mayevsky crane(to the upper point), mount the plug down. Install heat regulators if necessary.

With the help of adapters (futorok), transitions from right to left threads are provided from pipes of different diameters. For connecting batteries to the pipeline are sold sets with squeegees, adapters, couplings and valves. The kit is completed with gaskets that do not need additional waterproofing. Sometimes, when threaded connection of pipes and adapters, gaskets do not save, then use linen impregnated with linseed oil.

Important! Start winding the adapters by cleaning the pipes and joints: the presence of paint is not allowed in the joints. Work with emery "to bare metal." Otherwise, the paint will peel off over time and the joint will leak.

When installing the system yourself, do not save on the installation of cranes- otherwise, minor repairs will have to be done when the system is turned off and the pipeline is cut.

Many homeowners are not happy with the heating efficiency of their apartment. This issue is especially acute during severe cold weather. Sometimes poor heating is associated with a worn out radiator. In this case, the heating structure is replaced with more efficient and powerful equipment. Today, ceramic radiators, bimetallic, etc. are on sale. But the most reliable and durable are cast-iron models. If the battery is in excellent condition, it is impractical to change it. In this case, you can add sections to the radiator. This article is devoted to how to build up a heating battery.

At the moment, there are several schemes for connecting radiators.

Experts say that an incorrectly chosen scheme can lead to the fact that 50% of the heat will be lost.

If additional sections are connected incorrectly, the system will heat up unevenly. And the slightest mistake, a defect can cause leaks and breakouts. Therefore, it is important to know how to properly connect the radiators, and to do the work carefully and carefully.

The methods for connecting radiators are given below:


It should be noted that the series connection of heating radiators is the most reliable and economically viable. The easiest method to implement is to conduct one common channel for supplying the coolant.

What will it take to extend the battery?

Before connecting a heating radiator, you need to calculate how many sections you need to install for more efficient heating of the room. And purchase the required number of additional sections. Better to choose cast iron.

Also, before connecting the heating radiators correctly, you should prepare all the necessary tools, purchase some materials:

How to connect the battery?

Without understanding how to connect the heating batteries, without knowing the principle of operation of the heating system, it will not work to properly build up the radiator.

Preparatory work

The first step is to carry out preparatory work. This includes removing the radiator. It is necessary to remove the sections that are planned to be increased.

The battery must be cleaned, remove rust, dust and dirt.

Inspect the threaded hole that connected the structure to the pipe. There may be growths here. They must be removed with sandpaper. Otherwise, the intersection gasket will be leaking. And this can lead to the fact that the heating system will leak.

Attaching sections

Further, the sections are connected. The sections to be connected are tightly attached to the battery. Make a gasket. Using a radiator wrench, measure the distance to the nipple. The nipple is inserted into the battery to the marked length. The pipe wrench is used to rotate the radiator wrench. Then the nipple is wrapped in two opposite sections. Make 3 turns with the radiator wrench. Similar actions are done with the bottom of the battery.

Next, paronite gaskets and side plugs are taken and installed in the battery. In this case, a pipe wrench is used. The main thing is to tighten it very tightly to create a reliable, sealed structure. The section is connected to the radiator. The connection of the remaining sections is carried out in the same way.

Fastening the radiator to the wall

After all additional sections are attached, it is carried out. For this, hooks are installed at the level of the battery. The construction is hung up. All joints are fixed with fittings. Tighten with a wrench. All joints are treated with sealant. Recently, special adhesive tapes for pipes have appeared on the market.

Verification work

The resulting structure is inserted into the pipe at one end, and into the battery at the other. The joints are tightened tightly with a wrench. When the installation of the fitting is completed, waterproofing is carried out.

After the assembly of the radiators is completed, the system is inspected for defects. If everything is in order, a test run of the coolant is carried out. The first time the water is started up under reduced pressure. This allows you to detect where the connection is of poor quality and leaks. If leaks are detected, the water is turned off and work begins to eliminate the problem. The second time the coolant is started up under normal pressure.

After it was possible to connect the heating battery, it is necessary to let the radiator work for several hours. And after this time, check the condition of pipes, fittings, batteries.

Which battery connection scheme should I choose?

Since heating radiators can be connected to each other according to different schemes, we will consider which one is more convenient and efficient.

Serial connection of radiators is used most often. Since it provides a high level of reliability. Requires minimal maintenance. The technical costs are low. Up to four batteries can be connected in this way. The heater is connected to the system from below. When sagging radiators, pipes, it is necessary to put spacers.

The only drawback when connecting batteries according to this scheme is large heat losses. When water enters the top of the system, the battery cools down by about 7 degrees. The last radiators to heat the apartment will be worse. The temperature difference between the near and far batteries can reach 18 degrees. Thus, the room will be heated unevenly. But this problem can be solved by installing an additional electric boiler.
