The term “battery” refers to all sectional heating devices of aluminum, steel, bimetallic and cast iron types. To connect individual sections, upper and lower nipple nuts are used.
Nipple nuts are ring-type seals equipped with external thread at both ends of the element. In the inner part there are special grooves designed for installing a radiator key. By rotating it in one direction or another, you can close or open individual sections.
Heating batteries are disassembled into sections, as a rule, in the following cases:
Before disassembling aluminum radiator, you need to prepare the necessary equipment.
The role of the main tool is assigned to the nipple wrench:
The key has a series of notches, the spacing between which indicates the width of one section.
List of operations on how to disassemble a heating radiator with your own hands:
How to disassemble a right-hand type bimetallic heating radiator:
Most often, houses and apartments with old layouts are equipped with MS-140 cast iron batteries. Nipple nuts and sealing gaskets are also used to assemble their sections. Particularly difficult to disassemble old battery, because Over the course of its long-term operation, the spaces between the sections began to boil with rust. As a rule, in such cases, the niches for the keys are corroded by the coolant. It is also important to keep a significant mass of cast iron in mind. For example, the weight of one battery for 12 sections is 90 kg: it will be difficult to handle such a product alone.
To implement the procedure, you will need the following tools:
A metal rod flattened at one end is used as a radiator key. round shape, with a diameter of 18-20 mm. The dimensions of the flattened part are 28x40 mm, with a thickness of 6 mm. A ring is welded to the opposite edge of the rod through which the lever is threaded. The length of the radiator key should be half the largest battery for 12 sections, plus 30 cm.
It is very difficult to separate stuck intersection joints. In some cases, they become so attached that even significant physical efforts are powerless. IN similar situations Before disassembly, the joints are heated using a blowtorch or hair dryer.
How to disassemble a heating radiator made of cast iron:
Before starting the operation, it is important to find out in which direction the sections need to be twisted. If there is a nipple nut, screw it in turn onto the right and left ends of the battery: this makes it possible to determine the direction of rotation of the nipple. If the thread moves, it should not be completely unscrewed. To avoid distortions, the upper and lower nipples must be unscrewed one full turn alternately.
Heating systems, which became one of the first alternatives to cast iron devices. How to disassemble and assemble an aluminum heating radiator with your own hands, if repairs are necessary - actual question for homeowners.
In order to competently assemble and disassemble a system consisting of aluminum radiators, you should first of all know the strengths and weak sides, which are characteristic of this species. Among the advantages of this type of battery are the following:
Despite a large number of advantages, they have their disadvantages:
It is the disadvantages aluminum batteries require skills to disassemble them. It should be noted that similar problems are also relevant for bimetallic heating radiators.
It is necessary to disassemble aluminum radiators when updating the system, installing additional sections, or if necessary, eliminating leaks or changing o-rings. Repairing batteries yourself is not difficult if you follow a certain sequence.
For reference! The tools required for the work will be: wrench, screwdriver.
You can disassemble it into sections after dismantling it. They are connected to each other by nipple nuts, which have external threads and mounting bores. To carry out various manipulations with them, you need a special key in the form of a spatula with several notches. Place the nipple wrench into the mounting grooves of the nut and turn it a few times. This manipulation should be performed with all nipples until the sections are disconnected.
This method allows you to prevent distortions that are typical of aluminum radiators. If the unscrewing process is difficult, then at the end of the key there is usually a special hole where you can insert a rod for reinforcement.
Disassembled batteries should be thoroughly cleaned inside and, if necessary, all gaskets and seals should be replaced.
If the radiator is disassembled due to a leak, a special solution should be prepared. You need to take epoxy resin with bronze powder. Next, take a cable, which is usually used for cleaning sewers, and treat the entire inner surface batteries and leave to dry for half an hour.
Important! When working with epoxy resin All manipulations must be done quickly, since this substance hardens almost instantly.
Repair and diagnostics of bimetallic radiators is carried out in a similar way.
After diagnostics and troubleshooting, the batteries must be collected. The build process will be as follows:
Next, the batteries are connected to the heating system, and it is necessary to ensure that the coupling connects the coolant supply pipe as tightly as possible. After the system is installed, you can run the fluid and check for leaks.
All types of sectional heating devices, regardless of the material they are made of (aluminum, steel, cast iron, bimetal), are called batteries and are assembled according to the same principle. Their sections at the top and bottom are interconnected with nipple nuts.
Nipple nuts are ring seals with external threads applied to both ends of the element. Special grooves are created inside the part.
The radiator key is inserted into this recess. By rotating it, sections can be mated or separated.
Typically, you need to disassemble heating radiators with your own hands in the following cases:
Before disassembling an aluminum heating radiator or a bimetallic analogue, prepare the necessary tools.
A nipple wrench is used as the main device for work.
Note!
Insert the tool into the battery.
Count the number of notches.
This way you can simply find the nut of the required section.
The photo shows sections of an aluminum radiator being unscrewed.
For example, you need to twist the section on the right.
Now about how to disassemble a cast iron heating radiator. The most common of them in old houses and apartments are MS-140. Their sections are also assembled using nipple nuts and gasket seals.
If it is, it will be quite difficult to disassemble it:
Note!
It is worth remembering that cast iron is very massive.
For example, a radiator of 12 sections weighs 90 kg.
Therefore, it is better to work with a partner.
Prepare the following tools:
A radiator key, the price of which is not very high, is a round rod with a cross-section of 1.8-2 cm. The metal is flattened at one end. The width of this blade is 2.8x4 cm, thickness 0.6 cm.
A ring is welded to the rod at the opposite end. A lever is inserted into it to facilitate operation.
The length of the tool is half the length of the largest battery (12 sections), about 30 cm is added to this value.
Note!
Be sure to determine where the section should be curled.
When there is a nipple nut, tighten it, doing this alternately with the right and left sides.
This way you will determine in which direction the nipple should be twisted.
When the thread yields to your efforts, do not unscrew it immediately. Tighten the nipple one full turn, then repeat the operation with the upper nut. Thus, proceed until you unscrew the section. Such caution is necessary because cast iron may burst due to misalignment.
Disassembling and assembling heating batteries from different metals is almost the same. Small differences are in their weight or special distinctive properties materials. Watch the video in this article for more information.
Disassembling a heating battery into its component sections is a labor-intensive procedure, which is performed either in the event of an emergency leak in an emergency attack, or in the order of planned work, which for a number of reasons was necessarily postponed to another date, following the saying: “Until the thunder strikes...”.
It is better to take a philosophical view of the need to periodically disassemble the radiator, flush it from accumulated rust and replace worn gaskets as basic preventative measures for the heating system.
Along the way, time the disassembly of the heating battery with other repair activities in the apartment, including auditing the quality of cast iron sections for their further use, adjusting the number of sections in the battery, installing additional shut-off valves or moving the battery to another location.
Naturally, disassembling the battery can only be carried out if there is no water in the heating circuit. Therefore, the method of stopping the coolant supply is not considered in the regulations.
Then the disassembly work will include the following operations:
In most cases, the radiator is hung on reinforcing steel hooks driven into the wall. Before removing it from these hooks, you should disconnect the radiator from the heating pipes. If the pipes are already rusted through, then it is better not to stand on ceremony with them, but to saw off them near the plug at the end of the radiator. The radiator is removed from the hooks along with the protruding hoses.
The removed radiator is placed on a level place. It is necessary to remove the radiator caps. They can either have nipples or be blind plugs. Before applying force to unscrew, you need to determine the direction of the thread. Knowing how to disassemble a heating battery, use a pipe wrench to remove the radiator plugs. It is more difficult to unscrew the stuck threads of batteries that have been in use for a long time. It is necessary to use a blowtorch to heat the disassembled intersection joint. Place a wet rag on adjacent joints that do not need to be disassembled.
When the junction of two sections is separated, a loud click will be heard. By rotating the nipple, the sections are separated. Thus, the battery can be completely disassembled into its component parts.
After disassembling the radiator, the sections are cleaned of accumulated rust and pieces of old gaskets. On plugs, it is necessary to refresh the old thread in several passes. Then the sections are assembled together into a radiator, and the radiator plugs are screwed in. The radiator is hung in its place.
Disassembling an aluminum radiator is similar to the sequence outlined for cast iron batteries. The only difference is that these radiators are relatively new, so to unscrew threaded connections you don't need to put in a lot of effort.
As already mentioned, in anticipation of disassembly and dismantling work, you can adjust the number of docked battery sections so that the temperature in the home is comfortable. There are several methods for calculating the size of a heating battery, the most popular of which are calculations based on the area of the heated room. With sufficient accuracy they allow you to determine the optimal number of sections of the heating device.
They involve standard specific thermal power, certain sanitary standards for heating 1 sq. meters of residential premises with different ceiling heights. Its value is defined in the range from 100 W for a low room to 130 W for a standard room, taking into account two windows.
If we multiply the estimated area of the room by the specified standards, we get the rated power heating radiator, which could warm up this room. In the case of rooms with ceilings or windows higher than standard, a correction factor of 1.1 is introduced.
From the technical data sheet of the radiator model, we use the thermal power value indicated there for one section.
After dividing the value of the rated power of the heater required to heat the room by the rated power of the device, the required number of sections is obtained. Rounding it up, we arrive at the battery size.

1.Installation of bimetallic heating radiators: tips and recommendations
2. An exceptional case - repair of heating radiators
In the recent past, cast iron alloy was used to produce heating radiators.
Installation of such systems, which have a decent weight, was quite labor-intensive. In addition to this, difficulties were also caused by the need to regularly clean the radiator cavities from mechanical blockages deposited on the internal walls.
To date, many manufacturers have managed to solve this problem by using materials that reduce the weight of radiators and at the same time have high heat transfer. Replacement cast iron radiators on bimetallic ones will allow you to simplify the installation and maintenance of the heating system while maximizing all the advantages of heating systems made of cast iron (read also: “Installing cast iron heating radiators with your own hands”).
Bimetallic radiators, popular today, are among the highest quality systems that meet a number of indicators required by modern heating equipment:
Possessing all the qualities necessary for modern heating systems, bimetallic heating radiators have excellent appearance, which allows you to abandon the use of decorative grilles and barriers that impede the passage warm air into the room.
When choosing a radiator, you should determine the indicators that the purchased system must meet for the room in which it is to be installed:
If an existing system requires replacement, bimetallic heating radiators will become one of the best solutions taking into account the fact that they have all the advantages of aluminum heating systems, without the disadvantages inherent in the latter: instability to corrosion and possible destruction of the joints of radiators with pipes (read also: “Bimetal heating radiators: which ones are better to choose”).
One of the main conditions for further efficient work heating, which should be taken into account if you, having previously assessed the advantages of the option under consideration, purchased bimetallic heating radiators: installation and testing of the operation of the system require extreme care and attention.
Radiator installation work should be carried out only after careful study of the accompanying documentation.
In the attached heating system The instructions must describe in detail the entire progress of the work being carried out. There should also be tips and basic recommendations, following which you will certainly get a high-quality result. Installing bimetallic radiators with your own hands in this case will not present any difficulties, especially if you have some experience in carrying out such work.
However, it is advisable to consult experienced specialists with the required level of qualifications.
The work that needs to be done before you start installing bimetallic heating radiators is assembling the radiators themselves.
As a rule, this operation is performed by the manufacturer at the factory or in a store by qualified specialists, and you purchase a ready-to-install assembled system.
However, it is possible to assemble bimetallic heating radiators or rearrange individual sections at the installation site of the system.
Craftsmen with experience in such work should be involved in this work. A special key is required for operation.
When performing installation, you should pay attention Special attention to place the valve necessary to release air accumulated inside the battery (Mayevsky valve). This will eliminate the possibility of airing the heating system, which will prevent a decrease in heat transfer.
Filters should be installed in front of the valves to clean the coolant entering the system from mechanical particles. A plug should be installed at the bottom of the “blind” side of the radiator.
Proper installation of bimetallic radiators requires compliance with the following points:
In this case, close attention should be paid to installing them strictly level. Thanks to its low weight, the radiator is held very securely.
Radiators are connected to pipes using fittings, adapters and specially prepared copper pipes.
Installation of a bimetallic radiator, video tutorial:
Bimetallic radiators, in addition to more high level efficiency, much easier to operate and repair than monometallic systems.
Installation, testing and commissioning, carried out in accordance with the manufacturer's requirements, guarantee effective uninterrupted operation bimetallic heating systems for a long time. The need to repair heating radiators arises mainly in low-quality models, individual elements which are connected by spot welding.
In this case, temperature changes can cause damage to the system due to the difference in the behavior of steel and aluminum.
At best, the metal will simply make characteristic sounds. IN bimetallic radiators steel pipes fused with adjacent radiators under high pressure. By choosing models from well-known leading manufacturers who provide a guarantee for their products, you will purchase a high-quality product, which, compared to other radiators, has only one drawback - more high price(see also the article: “Replacing heating radiators with your own hands - do it right”).
However, by investing in such heating systems, you will eliminate the risk of any problems and provide your home with a reliable source of heat.
1.Technical features of cast iron batteries
2. Advantages of cast iron batteries
3. Disadvantages of cast iron radiators
4. Capable of installing cast iron radiators
It's no secret that such heating devices, as cast iron batteries have been used in almost all residential buildings for quite a long time.
They are still common today, but the development of technology is helping to ensure that these units are being replaced by more modern and functional radiators.
Namely:
In order to understand how the installation of cast iron heating radiators should proceed, it is necessary to study what technical characteristics these devices have, and also consider the principle by which cast iron heating radiators should be calculated.
Modern cast iron batteries are largely similar in their technical specifications with more expensive and innovative devices made of bimetal, aluminum and steel.
The working pressure inside cast iron batteries is eight atmospheres. Concerning optimal location these units, then it is best to place them in the space under window openings, which will increase heat transfer rates.
In order for the volume of heat transferred to be as large as possible, the right decision will periodically wash the inner surface of the batteries to clean it of rust and other harmful substances.
This will increase the productivity of the equipment, and at the same time extend the service life of cast iron heating batteries.
Considering such a heating device as a cast-iron heating radiator, the characteristics of this unit largely correspond to, and sometimes exceed, the characteristics of more modern products used for heating residential premises.
Among obvious advantages This type of radiator can be distinguished as follows:
Despite this, cast iron radiators are resistant to contaminants in water (read also: “Design and design of a heating radiator”);
To make installation easier, you can study various photos- and videos that can simplify the installation process.
Despite all the above advantages, cast iron radiators also have some disadvantages, among which it is especially important to mention the following:
And the increased inertia of cast iron equipment will not allow equipping the radiator with a mechanism for regulating the heat produced;
There may be several options for connecting cast iron batteries to a general heating system:
This option involves connecting those mechanisms that are based on a large number of sections. The supply pipe is connected to the upper fitting on one side of the battery, and the return pipe is mounted to the lower fitting on the other side.
If such a connection is made according to the sequential principle, the circulating water will move due to the pressure generated in the heating system.
Many owners, wanting to get rid of excess air in the pipes, talk about how to remove a cast-iron heating radiator.
However, this is not worth doing at all; it is enough to just install special Mayevsky cranes that serve precisely for this purpose. The main disadvantage of such a connection is that repairing cast iron batteries will be very problematic, since it will not be possible to dismantle such a structure without consequences.
This type of installation of a cast iron radiator will be relevant if the system pipes are located under the floor of the room or under the baseboard. This method is the most acceptable from the point of view of aesthetic properties, since no protruding communications are visible.
The most common installation method, the principle of which is to connect the supply pipe to the top fitting, and the outlet pipe to the bottom.
This installation option ensures good heat dissipation of the equipment, but if the connection is made the other way around, the operating power of the equipment will decrease by about 10%. If the heating of the coolant is weak, then experts recommend installing a water flow extension in the system specially designed for this purpose.
Thus, the water will leave through pipes connected to the return line.
Valves equipped at the battery inlet and outlet areas will allow you to easily remove the radiator and perform the necessary renovation work, the system will continue to function.
Main negative side this method - the need to maintain constant high pressure, otherwise the coolant circulation will be slow.
It is important to remember that even what is outdated by modern standards heating equipment can reliably serve for a very long time if you repair heating batteries with your own hands in a timely manner and provide the system with proper care.
In order to simplify the entire process of connecting cast iron batteries, you can always study various photos of these structures and diagrams of their installation, which are always available from specialists in the installation of such products.
Principles for installing cast iron heating radiators on video:
To assemble a cast iron radiator, you will need double-sided nipples and heat-resistant rubber gaskets.
A radiator key is also required.
The key for assembling a new radiator can be made from a piece of water pipe 15 mm. If the radiator sections are old, it is better to use a key forged from a rod.
The holes in the sections have internal threads.
On one side is right, on the other is left. The connecting nipple has the same system. The two sections to be connected must be placed on a flat surface, preferably on bars - they will slide on them more easily. Place rubber gaskets on the nipples, moving them to the middle. Bringing the sections closer together equal to length nipple, carefully tighten the nipple (it will screw into both internal threads sections) a few turns by hand.
The same goes for the other side of the section.
Next, the radiator key is inserted and by alternate turns of the key, first one nipple, then the other, we connect the sections to each other. We attach the remaining sections in the same way. If the rubber seals are made of high-quality heat-resistant rubber, then their service life will be the same as the service life of the radiator.
