Wiring diagram for home heating radiators. Independent connection of heating radiators to different heat supply systems. Place to connect

Proper connection of heating radiators with a two-pipe system is a guarantee of comfort in the house. By itself, this system allows you to distribute heat to several rooms. But after all, you need radiators to effectively heat your house or apartment!

In order for the two-pipe system to work well and ensure uniform heating of the entire building, it is necessary to properly connect and. The type of connection is also important, and there are several of them. In this publication, we will talk about their advantages, disadvantages and features.

Scheme of a two-pipe system

The basis of a two-pipe heating system is two pipes. Through one, heated water enters the batteries, through the other, cooled water is discharged from them. Heating is produced by any source of heat -, boiler, boiler.

If the connection of heating radiators with a single-pipe heating system is sequential and the water cools down as the batteries pass, then with a two-pipe heating system it is parallel and the heating is more uniform.

The difference between a two-pipe heating system and a single-pipe heating system is that it heats all radiators almost evenly. Small heat losses are possible due to the distance from the heater - the longer water is coming through the pipe, the more it cools.

Efficient connection of heating radiators

There are four main schemes for connecting heating radiators with a two-pipe system:

• Lateral;
• top;
• lower;
• Diagonal.

Some radiators are designed for certain types of connection, but there are those that are considered universal.

Side connection

With this type of connection, water enters and leaves the heating battery from the same side. At the same time, it passes more slowly through sections that are farther from the connection points. Due to this, the temperature in this place is lower and the radiator heats less efficiently.

Top connection

If you connect a conventional radiator like this, it will be ineffective. warm water will flow in its upper part and warm up only it.

There are radiators designed for top connection. A plug is installed in them, which redirects water to the lower part of the radiator and it circulates as in a diagonal one. Such radiators warm up well over the entire area.

Bottom connection of heating radiators

If you connect a conventional radiator in this way, the main flow of water will pass in its lower part. Part of it due to natural convection will rise up and the radiator will warm up, but not completely.

Heating system is created in order to provide heat to everyone who lives or is in a residential building, apartment or building, while the connection of heating radiators must be done correctly. Comfortable is considered to be the air temperature in the room in the range from 18°C ​​to 25°C. The power of heating devices should be such that it compensates for heat loss through walls, doors, windows and other protective structures facing the street.

The scheme that determines the connection of heating radiators in your own house is selected at the design stage of the building before the start of execution construction works. True, measures to improve or repair the heating structure can also be carried out during the use of the premises.

Of course, if there is a central heating main in the settlement best solution The issue with heat supply is the connection to it. In the absence of centralized heating, the arrangement of an autonomous heating system becomes relevant.

Factors affecting heating efficiency

The efficiency of the heating structure depends on several factors:

1. Wiring of elements of the heating system. The degree and uniformity of space heating, and, accordingly, the amount of money spent on heat supply to a house or apartment, depends on the correctness of this work.
2. Choice heating equipment . Everything that is needed to create a heating system is acquired on the basis of a professionally performed calculation of technical and financial indicators. The fact is that the decision on how to properly connect heating radiators and the choice of appropriate equipment contributes to achieving maximum heat transfer with minimal fuel consumption.

3. Mounting method main pipelines, heating boiler, circulation pump, connection of radiators, regulating and locking elements. An incorrect installation of any of the links of the heating structure can result in the failure of the entire system.
4. Availability of special knowledge and skills carrying out works related to the design and installation of the heat supply structure. To perform calculations and determine the heating scheme of the house, including the option of how to connect heating radiators in a particular case, professionals in the field of heat engineering should. Despite the fact that the involvement of specialists will lead to an increase in the cost of arranging heating, you should not save on this. See also: "".

The choice of the connection scheme for heating batteries

When the choice of the type of heating boiler is completed, the scheme for connecting the heating batteries in the house is determined. It can be single pipe or double pipe.

The radiator connection itself is performed in one of three ways:

• bottom;
• side;
• diagonal.

If, when deciding how to connect the heating battery, one-sided piping was planned, then the number of sections on one device should not exceed 12 for gravity heating networks and 24 for systems equipped with a circulation pump.

If it is necessary to install a larger number of sections, it is necessary to use a versatile piping connection to heating radiators. When installing heating appliances, one should not forget about the throughput of the straight pipe and the return pipe, which depends on their diameter and roughness coefficient.

Efficient heat transfer can be achieved if the batteries are optimally placed, or rather, if the installation distance of the devices in relation to the walls is observed, flooring, window and window sill.

Installation instructions and how to properly connect a heating radiator provides for the following standards:

• the device should be at a distance of 10 - 12 centimeters from the floor;
• it should be installed no closer than 8-10 centimeters to the windowsill;
• the back panel cannot be placed closer than 2 centimeters from the wall;
• when installing batteries, it is necessary to provide for the adjustment of the degree of their heating, both in manual and automatic modes. For this, special thermostats are purchased (more details: "");
• in order to repair or replace the radiator, valves, valves and manual taps should be provided. They will allow you to disconnect the product from the heating system;
• on the devices you need to put Mayevsky cranes, such as in the photo. With their help, air that has entered the system is removed.

Installation of steel or other types of radiators is carried out in a certain sequence:

• carry out preliminary marking for the placement of brackets that are attached to the wall;
• Mayevsky cranes are mounted on appliances;
• install various shut-off and other elements - valves, plugs, taps and regulators;
• before connecting a heating radiator, it is placed on brackets and aligned to a horizontal level;
• the device is connected to the pipeline using transitional runs;
• make pressure testing and test run of water.

Serial connection of heating radiators

With this method, the batteries are connected using one pipe. Most often, if a serial connection of heating radiators is required, then in order to increase the power of the heating devices and ensure a sufficient degree of heating of the room, it is necessary to increase the number of sections to the end of the line.

The series connection method is characterized by an uneven distribution of thermal power. As a result, the first of the radiators heats up much more than the subsequent ones, and the last device in the circuit will be barely warm.

Despite a number of inconveniences, this way in demand due to its simplicity, and the adjustment of the desired degree of heat transfer is carried out by building up several sections of batteries in different places of the heating structure. See also: "".

Examples of connecting heating radiators in the video:

The heating system is one of essential element housekeeping. Heating a house directly depends on the chosen heating system, and the way it was connected. Unfortunately, not everyone knows how best to connect a heating radiator with their own hands.

But first, it is worth understanding the varieties of heating systems. This is necessary, since the connection may have its own characteristics depending on the selected system.

Varieties of heating systems

Depending on the principle of connection, there are single-pipe and two-pipe heating systems.

One-pipe system - is the most common, as it is installed in most apartment buildings. It is a looped pipe to which heating elements are connected in series.

It is called so because only one pipe is used to supply water to the radiators and return it to the boiler. This method of connection has a number of its positive features and disadvantages.

The advantages of such a system:

• economy, in terms of the necessary materials;
• small time costs during installation;

Its disadvantages are:

• There is no possibility of a top connection;
• Due to the series connection, the heat dissipation of the first heating element is much higher than that of the last one in the system;
• Heat transfer cannot exceed the rate calculated during installation;

Two-pipe system - differs from the previous one in that independent pipes are responsible for the supply and return of water. Also, when using this model, radiators are connected in parallel.

Advantages of this connection method:

• the ability to regulate the supply of coolant by installing a tap in front of the radiator;
• uniform heating of all elements;

The disadvantages are the higher consumption of materials and the more time-consuming installation process.

At the moment, there are various schemes and methods for connecting radiators. But there are a few generally accepted features that are recommended to be considered, regardless of the installation method.

The main place for installing radiators is the area under the windows. This is done to keep cold air from the glass into the house, and also prevents condensation.

In this case, the length of the device should not exceed 70% of the width of the window, otherwise the windows will periodically fog up. Also, for optimal heat circulation, the radiator should be 8 to 12 cm from the floor, and 3 to 12 cm from the wall.

Before installation, check the heating system, as depending on it, it may be necessary to different types radiators.

Connecting a radiator at home

Before direct installation, you should make sure that you have all the elements necessary for installation. If a one-pipe connection method has been chosen, it is recommended to purchase a bypass, which will allow the installation of a radiator to be removed without having to shut off the entire system.

Also, according to the dimensions and connection method, connecting elements are selected if they are not included in the kit for the radiator. This also includes shut-off valves and squeegees, which are also selected according to size.

It is highly desirable to install a Mayevsky crane in the design, which will periodically bleed the accumulated air from the system.

On the Internet, there are a large number of photos showing the connection of heating radiators, in order to select the optimal configuration of components.

It is worth noting that when installing any types of radiators, with the exception of cast iron, do not remove the packaging until the installation work is completed.

Instructions for the correct connection of the radiator

One of the fundamental operations is the marking and installation of brackets. It is recommended to do this in accordance with the above instructions, or in accordance with the instructions of the radiator manufacturer.

It is important not to allow too much distortion, as this can lead to undesirable consequences in the form of stagnation. After installation, the device must rest firmly on all fasteners.

Next, unscrew all the plugs from the radiator. If the one-pipe method is used, first of all, a bypass is connected to the radiator, which is pre-equipped with a valve. Otherwise, a control valve is connected to the device using a surge.

Using spurs, heating element connected to the heating system. To ensure sealing, if necessary, it is recommended to use tow or similar sealant.

The installation of the radiator into the system is completed, but for its full operation, it will also require pressure testing of the device. To carry out this procedure, it is recommended to contact a plumber, as professional equipment is required.

Photo of the process of connecting heating radiators

The efficiency of the heating system primarily depends on the competent choice of the heating battery connection scheme. It is ideal if, with a small fuel consumption, radiators are able to generate the maximum amount of heat. In the material below, we will talk about what are the schemes for connecting heating radiators in an apartment building, what is the peculiarity of each of them, as well as what factors should be considered when choosing a particular option.

Factors Affecting Radiator Efficiency

The main requirements for a heating system are, of course, its efficiency and economy. Therefore, its design must be approached thoughtfully so as not to miss all sorts of subtleties and features of a particular living space. If you do not have sufficient skills to create a competent project, it is better to entrust this work to specialists who have already proven themselves and have positive feedback from customers. Relying on the advice of friends who recommend certain methods of connecting radiators is not worth it, since in each case the initial conditions will be different. In other words, what works for one person doesn't necessarily work for another.

However, if you still want to deal with piping to heating radiators yourself, pay attention to the following factors:

• size of radiators and their thermal power;
• placement of heating devices inside the house;
• connection diagram.

The modern consumer can choose from the most various models heating appliances - these are mounted radiators made of various materials, and plinth or floor convectors. The difference between them is not only in size and appearance, but also the methods of supply, as well as the degree of heat transfer. All these factors will affect the choice of options for connecting heating radiators.

Depending on the size of the heated room, the presence or absence of an insulating layer on the outer walls of the building, the power, as well as the type of connection recommended by the radiator manufacturer, the number and dimensions of such devices will vary.

As a rule, radiators are placed under windows or in the piers between them, if the windows are at a great distance from each other, as well as in the corners or along the blank wall of the room, in the bathroom, hallway, pantry, often on the stairwells of apartment buildings.

To guide thermal energy from the radiator into the room, it is advisable to attach a special reflective screen between the appliance and the wall. Such a screen can be made from any heat-reflecting foil material - for example, penofol, isospan or any other.

Before connecting the heating battery to the heating system, pay attention to some features of its installation:

• within one dwelling, the level of placement of all batteries should be the same;
• the ribs on the convectors must be directed vertically;
• the middle of the radiator must coincide with the center point of the window or can be shifted 2 cm to the right or left;
• the total length of the battery should be from 75% of the width of the window opening;
• the distance from the window sill to the radiator must be at least 5 cm, and there must be at least 6 cm of clearance between the appliance and the floor. It is best to leave 10-12 cm.

Please note that from right choice ways to connect heating radiators in an apartment building will depend not only on the heat transfer of the battery, but also on the level of heat loss.

It is not uncommon for apartment owners to assemble and connect the heating system, following the recommendations of friends. In this case, the result is much worse than expected. This means that mistakes were made during the installation process, the power of the devices is not enough to heat a particular room, or the scheme for connecting heating pipes to batteries is inappropriate for this house.

Differences between the main types of battery connections

All possible types connections of heating radiators differ from each other in the type of piping. It may consist of one or two pipes. In turn, each of the options involves a division into systems with vertical risers or horizontal lines. Quite often, horizontal wiring of the heating system in an apartment building is used, and it has proven itself well.

Based on which option for connecting pipes to radiators was chosen, the scheme of their connection will directly depend. In heating systems with a single-pipe and two-pipe circuit, the lower, side and diagonal method of connecting radiators is used. Whichever option you choose, the main thing is that enough heat enters the room for its high-quality heating.

The described types of pipe wiring are referred to as a tee connection system. However, there is another variety - this is a collector circuit, or beam wiring. When using it, the heating circuit is laid to each radiator separately. In this regard, the collector types of battery connection have a higher cost, since a lot of pipes will be required to implement such a connection. In addition, they will pass through the entire room. However, usually in such cases, the heating circuit is laid in the floor and does not spoil the interior of the room.

Despite the fact that the described collector connection diagram assumes the presence a large number pipes, it is increasingly used during the design of heating systems. In particular, this type of radiator connection is used to create a water "warm floor". It is used as an additional source of heat, or as the main one - it all depends on the project.

Single pipe scheme

A single-pipe heating system is called, in which all radiators, without exception, are connected to one pipeline. At the same time, the heated coolant at the inlet and cooled down at the return moves along the same pipe, gradually passing through all the heating devices. In this case, it is very important that the internal section of the pipe is sufficient to fulfill its main function. Otherwise, all heating will be inefficient.

A heating system with a single-pipe circuit has certain pros and cons. It would be erroneous to believe that such a system can significantly reduce the cost of laying pipes and installing heating appliances. The fact is that the system will function effectively only if it is properly connected, taking into account a large number of subtleties. Otherwise, it will not be able to heat the apartment properly.

Savings in the arrangement of a single-pipe heating system really take place, but only if a vertical supply riser is used. In particular, in five-story houses, this wiring option is often practiced in order to save materials. In this case, the heated coolant is fed upwards through the main riser, where it is distributed to all other risers. Hot water in the circuit gradually passes through the radiators on each floor, starting from the top.

As the coolant reaches the lower floors, its temperature gradually decreases. To compensate for the temperature difference, radiators with a larger area are installed on the lower floors. Another feature of a single-pipe heating system is that it is recommended to install bypasses on all radiators. They allow you to easily remove the batteries in case of need for repair, without stopping the entire system.

If heating with a single-pipe circuit is made according to a horizontal wiring scheme, the movement of the coolant may be associated or dead-end. Such a system has proven itself in pipelines up to 30 m long. At the same time, the number of connected radiators can be 4-5 pieces.

Two-pipe heating systems

Inside the two-pipe circuit, the coolant moves through two separate pipelines. One of them is used for the supply flow with hot coolant, and the other for the return flow with cooled water, which moves towards the heating tank. Thus, when installing heating radiators with bottom connection or any other type of tie-in, all batteries warm up evenly, since water of approximately the same temperature enters them.

It is worth noting that a two-pipe circuit when connecting batteries with a lower connection, as well as when using other schemes, is the most acceptable. The fact is that this type of connection provides a minimum amount of heat loss. The water circulation scheme can be both associated and dead-end.

Please note that if there is a two-pipe wiring, it is possible to adjust the thermal performance of the radiators used.

Some owners of private houses believe that projects with two-pipe types of radiator connections are much more expensive, since more pipes are required to implement them. However, if you look in more detail, it turns out that their cost is not much higher than in the arrangement of single-pipe systems.

The fact is that a single-pipe system assumes the presence of pipes with a large cross section and a radiator large sizes. At the same time, the price of the thinner pipes required for a two-pipe system is much lower. In addition, in the end, unnecessary costs will pay off due to better circulation of the coolant and minimal heat loss.

With a two-pipe system, several options are used, how to connect aluminum radiators heating. The connection can be diagonal, side or bottom. In this case, the use of vertical and horizontal joints is allowed. In terms of efficiency, the diagonal connection is considered the best option. At the same time, heat is evenly distributed over all heating devices with minimal losses.

The lateral, or one-sided, connection method is used with equal success in both single-pipe and two-pipe wiring. Its main difference is that the supply and return circuits cut into one side of the radiator.

Lateral connection is often used in apartment buildings with vertical supply riser. Please note that before connecting a heating radiator with side connection, it is necessary to install a bypass and a valve on it. This will allow you to freely remove the battery for washing, painting or replacing without shutting down the entire system.

It is noteworthy that the efficiency of one-sided tie-in is maximum only for batteries with 5-6 sections. If the length of the radiator is much longer, with such a connection there will be significant heat losses.

Features of the bottom piping option

As a rule, a radiator with a bottom connection is connected in cases where unpresentable heating pipes must be hidden in the floor or in the wall so as not to disturb the interior of the room.

On sale you can find a large number of heating devices in which manufacturers provide a lower supply to heating radiators. They are available in various sizes and configurations. At the same time, in order not to damage the battery, it is worth looking at the product passport, where the method of connecting one or another model of equipment is prescribed. Typically, the battery connection node provides Ball Valves that allow you to remove it if necessary. Thus, even without experience in such work, using the instructions, you can connect bimetallic heating radiators with a bottom connection.

The circulation of water inside many modern radiators with a lower connection occurs in the same way as with a diagonal connection. This effect is achieved due to an obstacle located inside the radiator, which ensures the passage of water throughout the heater. After that, the cooled coolant enters the return circuit.

Please note that in heating systems with natural circulation bottom connection of radiators is undesirable. However, significant heat losses from such a connection scheme can be compensated by an increase in the thermal power of the batteries.

Diagonal connection

As we have already noted, the diagonal method of connecting radiators is characterized by the smallest heat loss. With this scheme, the hot coolant enters from one side of the radiator, passes through all sections, and then exits through the pipe from the opposite side. This type of connection is suitable for both one- and two-pipe heating systems.

Diagonal connection of radiators can be performed in 2 versions:

1. The hot coolant flow enters the upper opening of the radiator, and then, having passed through all sections, exits the lower side opening on the opposite side.
2. The coolant enters the radiator through the bottom hole on one side and flows out from the opposite side from above.

Connecting in a diagonal way is advisable in cases where the batteries consist of a large number of sections - from 12 or more.

Natural and forced circulation of the coolant

It is worth noting that the method of connecting pipes to radiators will also depend on how the coolant circulates inside the heating circuit. There are two types of circulation - natural and forced.

The natural circulation of the liquid inside the heating circuit is achieved through the application of physical laws, while optional equipment no need to install. It is possible only when using water as a heat carrier. If any antifreeze is used, it will not be able to freely circulate through the pipes.

Heating with natural circulation includes a boiler for heating water, expansion tank, 2 pipelines for supply and return, as well as radiators. In this case, the operating boiler gradually heats the water, which expands and moves along the riser, passing through all the radiators in the system. Then, the already cooled water flows back into the boiler by gravity.

To ensure the free movement of water, horizontal pipes are mounted with a slight slope to the direction of movement of the coolant. The heating system with natural circulation is self-regulating because the amount of water varies according to its temperature. When the water is heated, the circulation pressure increases, which ensures uniform heating of the room.

In systems with natural fluid circulation, it is possible to install a radiator with a bottom connection, provided a two-pipe connection, and also use a top-wiring scheme in a one- and two-pipe circuit. As a rule, this type of circulation is carried out only in small houses.

Please note that air vents must be provided on the batteries through which air locks can be removed. Alternatively, risers can be equipped with automatic air vents. It is advisable to place the heating boiler below the level of the heated room, for example, in the basement.

If the area of ​​\u200b\u200bthe house exceeds 100 m 2, then the method of circulation of the coolant must be forced. In this case, it will be necessary to install a special circulation pump, which will ensure the movement of antifreeze or water along the circuit. The power of the pump depends on the size of the house.

The circulation pump can be mounted on both the supply and return pipes. It is very important to install automatic bleeders at the top of the pipeline or provide Mayevsky taps on each radiator in order to remove air locks manually.

The use of a circulation pump is justified both in one- and two-pipe systems with a vertical and horizontal type of radiator connection.

Why is it important to correctly connect heating radiators

Whichever connection method and type of radiator you choose, it is very important to make competent calculations and install the equipment correctly. At the same time, it is important to take into account the characteristics of a particular room in order to choose best option. Then the system will be as efficient as possible and will avoid significant heat losses in the future.

If you want to assemble a heating system in a large expensive mansion, it is better to entrust the design to specialists.

For houses of a small area, you can handle the choice of wiring diagram and installation of batteries yourself. It is only necessary to consider the quality of a particular connection scheme and study the features of the installation work.

Please note that the piping and radiators must be made of the same material. For example, cast-iron batteries cannot be connected plastic pipes because it is fraught with trouble.

Thus, provided that the features of a particular house are taken into account, the connection of heating radiators can be done independently. A well-chosen scheme for connecting pipes to radiators will minimize heat loss so that heating devices can work with maximum efficiency.

Any modern batteries, whether aluminum, cast iron or bimetallic, come with four open pipes for connecting to the heating main. In accordance with design features wiring, a scheme for connecting radiators with connected pipes is selected, and the remaining holes are closed with plugs or air vent valves.

In this article, we will study possible options battery installation and tell you which scheme is better in terms of heat transfer efficiency.

It is believed that the best results from your radiator can be obtained using a diagonal connection. In order to correctly implement this method, you need to connect the inlet pipe to one of the upper inlets, and the return pipe to the lower one from the opposite edge. Then the coolant will circulate along the optimal route, capturing the largest part of the surface of the heater.

This combination is especially effective if the radiator consists of a large number(more than 10) sections. All other types of connections in this case will noticeably lose.

Therefore, the diagonal connection is considered a reference, and all manufacturers indicate the parameters of their equipment regarding this version of the heating device.

The disadvantages of this method include:

• high consumption of pipes in the system;
• the inability to hide communications in a wall or in a box;
• complex wiring geometry;
• inconvenient installation.

A diagonal scheme is used in cases where the main requirement is maximum heat transfer, and considerations of aesthetics and design fade into the background. Due to the inefficiency and complexity of wiring, this method of installing radiators is practically not used in multi-storey buildings.

Bottom connection

In contrast to the diagonal, the lower method of connecting batteries does not allow you to optimize the heating system in terms of performance, but it does provide the ability to make the radiator almost invisible.

Such a connection (it is sometimes called Leningrad), due to the peculiarities of the passage of the coolant between the inlet and outlet collectors, reduces the efficiency in the system by 10-15%. Moreover, these losses become so tangible only in apartment buildings with a large length of the highway.

If you plan to install a radiator in your own home (especially a one-story home), the bottom wiring diagram is a great option.

The upper part of the battery warms up worse than the bottom, this becomes especially noticeable when the internal cavities are clogged or aired. In these cases, cleaning and removal of air is required using Mayevsky taps.

side scheme

Most often, radiators of the heating system, especially in apartment buildings, are mounted according to the side scheme. Its essence lies in the fact that both lines approach the battery from one side.

Advantages lateral connection:

• high efficiency;
• convenient installation;
• savings on pipes;
• the possibility of organizing a bypass between the mains for the installation of control valves.

When comparing diagonal and lateral wiring, the advantage should be given to the latter, because the difference in efficiency is only a few percent, and the benefits of lateral connection are obvious.

The diagonal scheme starts to win if you need to connect a radiator with a large number of sections or organize a series of several powerful batteries. A proper understanding of these features will help to optimally distribute the radiators in the system.

Radiator location

The radiator is best installed under the window. This well-known rule is explained very simply: it is there that the heating battery will create best conditions preventing cold air from entering the room.

In a city apartment, windows and doors are the most important sources of heat loss. In private houses, as we have already noted, a roof and a floor are added to them. The battery under the window sill will create a curtain of warm air, which, as you know, tends to rise when heated, and will not let the cold inside.

If there are several windows in the room, it is better to distribute the radiators between them and connect them in series. Also, experts recommend putting several heating points in corner rooms.

The following tips will help you correctly place the radiator:

• The distance of the battery to the floor and the window sill must be at least 10 cm. Otherwise, its efficiency will decrease, and it will be inconvenient to clean under it;
• Do not deepen the radiator much towards the wall, it is better to leave a gap of about 5 cm;
• When using decorative protective screens, the efficiency of radiators is reduced by 10-15%.
• In terms of heat transfer, aluminum radiators have an advantage, but in city apartments it is better to install bimetallic products.

And one more important point: it is forbidden to independently change the connection scheme of radiators, their connection to each other or install shut-off valves in the absence of bypasses in apartment buildings. All alterations in the heating system must be coordinated with the Management Company.

Installation of radiators

Self-installation of radiators will not cause problems in the heating system in the future, if you correctly fulfill all the requirements for such work and ensure the tightness of all connections. In addition, some types of batteries require care when handling: aluminum and bimetal radiators have a fairly soft outer casing that can be easily crushed upon impact.

The installation process is carried out in the following order:

1. Removing the old radiator(if necessary). Naturally, the heating main must be blocked at the same time;
2. Marking the place of installation. Radiators are usually hung on a special bracket that is attached to the wall. Fasteners in the kit are most often designed for concrete or brick walls. If you want to hang the radiator on a soft wall, such as drywall, you must use special wall plugs. Aluminum and bimetallic batteries will not create dangerous loads for such a wall, but cast iron version better not to use here. The bracket must be installed so that the heatsink is positioned according to the requirements described in the previous section;
3. Now you need assemble the battery. To do this, we screw the adapters that come with the kit into all four mounting holes. Usually two of them are left-handed and two are right-handed, so care must be taken. Further, depending on the connection scheme, we drown out the unused collectors, one with a Mayevsky tap, and the other with a special locking cap. All joints are carefully sealed;
4. To prevent water leakage at the joints we lay sanitary flax. Fum tape is better not to use here. Flax must be wound correctly: for the right thread, clockwise, and for the left, in the opposite direction. In this case, when screwing onto the thread of the connected elements, the flax will not be knocked out from under them. For reliability, the connection can be additionally sealed by special means, for example, Unipak paste;
5. We fasten ball valves to the places of supply of main pipes. They will allow you to remove the radiator for cleaning and maintenance in the future, without stopping the operation of the entire system;
6. Now there is only hang the radiator on the bracket and connect the pipes to it. We seal the joints according to the above algorithm.

So, we have considered all possible types of connections for heating batteries. If you are just planning the structure of the system for your own housing, then you can choose the most suitable scheme. If you live in a city apartment, you do not have such freedom. In any case, understanding the principles and features of connecting radiators will allow you to independently maintain and install heating devices in your home.
