How to build a heating battery
Probably, many are familiar with the situation when in winter, in severe frosts, in the apartment it becomes quite cool, despite the fact that they are drowned enough in the boiler room. So what is the main reason? Perhaps your heating radiators simply can not cope with the load? What to do in such situations?
If the cast.Iron battery is installed, which until now are in excellent condition, then they are inappropriate to replace them. Then there remains only one option, add additional sections to the radiator, that is, build it up. And how to build a heating battery consider in more detail. (Cm. Also: site map 2)
Preparation for work
It should be noted that the sections are sold in a piece, so you can always buy the required amount. It is important to take components of one manufacturer. Then you can be sure that all elements will be the same and outwardly and from the point of view of the working parameters of the assembled radiator.
- Divorce key with a range of work from 0 to 35 mm.
- Key for radiators. You can use homemade, but for its manufacture you will need to make a lot of efforts. Better to buy ready.Made.
- Paronite gaskets. 2 pieces for each added section. One for each nipple. Installed in the center of the thread.
- Nipples. 2 pieces for each added section. Often come in the kit when selling.
Assembly of additional sections of the heating radiator
The radiator and the added section are laid on a flat surface, and it is easier to make assembly on the floor, literally on the knees than on the apparent comfortable table. Both nipples with a parony or rubber, planted on anacular smooth middle part, are screwed into a larger radiator threaded in cleaned and rust. From the free end of the nipple, they are slightly squeezed by the attached additional section.
Applying sealants for seals in the junction is not required. But if the remains of the old or factory gaskets are preserved on the ends of the crimping planes of the old radiator and the new section, then they need to be carefully removed without subsequent stripping. The thread should be tightened evenly, without applying excessive efforts.
It is important! When tightening the threads, the nipples rupture or the breakdown of the thread on the radiator section is possible, so it is categorically not to rely on the maximum possible efforts under the pretext that the stronger the tightening, the better.
On both nipples alternately in two stages (preliminarily “half of strength” and finally. A little less than the most possible effort), tighten the thread to the key to complete close to a single sections. When twisting, it is advisable to alternately do on average one turnover for each nipple, this will not allow dangerous overloads on the thread.
The same sequence of work is observed for aluminum and bimetallic radiators. Small differences only in other sizes of nipples and keys, probably smaller efforts during disassembly than for cast.Iron old radiators, more convenient marking on the futures for thread directions.
The collected extended battery must be hanged back on prepared brackets and connect to central heating pipes.
To increase the heating radiator, you must wait for the end of the heating season. Before you make sure of the procedure, it is necessary to remove the battery, and then disassemble it. But before these actions it is necessary to block water.
In old radiators, dirt and rust often appear between the sections. Naturally they will need to be removed. You can do this with a metal brush or sandpaper. After that, you can put on the gasket and connect the radiator sections.
Before building the radiator, it is necessary to put the heating battery on the floor along with the new sections. Next, proceed to the fastening of the nipple. But be sure to monitor the position of the thread. Start twisting nipples is recommended on the left. At the same time, you need to make it on 1 round on the left of the battery. Then we carry out the same actions with the right side of the heating radiator.
It is necessary to control the position of the intersecination laying. It should be strictly in the middle of the nipple. The battery sections should be tightly attached to the nipple. After that, you can insert the radiator key into the radiator, and screw the nipple with the divorce key in the battery section.
For high-quality extension of heating radiators, it is necessary to tighten the nipple by 3-4 turns. Then you can go to the other side of the radiator and also twist the nipple for 3-4 turns. Such a procedure must be repeated until the sections will fit tightly to each other.
After the sections are increased, it is necessary to install side traffic jams that are produced for cast.Iron radiators. And also you need to install special gaskets. They are made of paronite. Check the surface where the gasket will be laid. If there are rust or other defects on it, then they must be eliminated with sandpaper. After that, you can install traffic jams. They must be tightly tightened with a pipe key.
Dismantling of cast.Iron heating radiators
The disassembly of cast.Iron radiators sometimes becomes a very laborious process, but necessary.
Dismantling scheme of cast-iron heating radiators: a-capture by nipples of sections threads 2-3 threads of threads; b. Arguing nipples and docking sections; c. Connecting the third section; g. Grouping of two radiators; 1. Section; 2. Nipple; 3. Laying; 4. Short radiator key; 5. Crowbar; 6. Long radiator key.
A new or old radiator is placed in an even place. At least on one side you need to remove ordinary footstorms or deaf. Plugs. On different sections of radiators, they can be with the left or right thread. Typically, cast.Iron footballs have the right thread, plugs. Left. If there is no disassembly skills, and there is a free section, it is better to know before applying the force what kind of type this thread and which way should rotate the key. If the thread is left, when disassembling cast iron batteries, you need to rotate the key on the way.
As with unscrewing any nuts, first you need to “tear off” the foot from the place, t.E. Crank them for a quarter of turnover on both sides of the battery. Then the footballs are twisted so that a gap of several millimeters forms between the sections. If you let go of the footer more, the whole structure will begin to bend under its own weight and due to the efforts made. In this case, the thread can jam. To prevent this from happening, an assistant who will impede the bending to the disassembled battery.
Typically, the disassembly of old heating radiators is difficult in the fact that the foot and sections have “closed”. In order to disassemble such a battery, you will have to use an autoogen or a soldering lamp. The connection place is warmed up in circular movements. As soon as it is warm enough, the footballs are twisted. If it was not possible to twist the first time, the actions are repeated.
If there is not enough strength to disassemble the battery, you need to increase the length of the key. An ordinary pipe is used, which serves as a racal.
Similarly, built.In nipples are unscrewed for fragmentation of cast.Iron radiators.
If the considered methods were not able to disassemble the cast.Iron battery, it remains to cut it with a corner grinding or autogen or break down in a lying position with a sledgehammer. You need to divide or cut one section carefully. After this operation, the clutch between the sections may weaken, the battery will be able to disassemble, save the remaining sections.
The use of a “liquid key” or a WD liquid does not give an effect, since in the old cast.Iron batteries the feet were sealed with flax and paint, and the liquids will not fall into the thread.
Can the owner of the apartment independently increase the number of sections in the battery?
The heating system of an apartment building is a common property, and therefore, the change of radiators of the same type (for example. Aluminum) for radiators of a different type (for example. Cast iron) requires mandatory preliminary approval.
During development, many factors are taken into account: in which climatic zone the house is located, what material is made of and t. D. Information about the heating radiator installed in the house, the number of sections should be contained in the design documentation for a specific house.
In addition, according to paragraph 35 of the Rules for the provision of utilities to citizens approved by the Government Decree of May 06, 2011, the consumer is prohibited arbitrarily:
Drain the coolant from the heating system without the permission of the contractor; unauthorizedly join the intra.House engineering systems or join them bypassing collective (common house), general (apartment) or individual metering devices, make changes to the intra.House engineering systems without making changes to the technical documentation for a multi.Apartment or residential building or in a technical passport dwelling;
Arbitrarily increase the heating surfaces of heating devices installed in the living room over the parameters indicated in the technical passport of the dwelling; arbitrarily violate seals on metering devices, dismantle metering devices and carry out actions aimed at distorting their readings or damage.
The extension process
Before building a heating battery, if it is cast.Iron, you should remember that this can only be done after the end of the heating season! Indeed, in order to add new sections of such batteries, it will be necessary to completely disassemble the batteries. And if this is done in winter, then the entire system will need to be blocked. And if you live in an apartment building, hardly one of your neighbors will agree to spend several hours without heat.
Therefore, such a process should be postponed until warm times. How to build a radiator of heating from cast iron? Consider the process in more detail. We will need the following tools:
- Radiator or divorce keys;
- Nipples clearly for cast.Iron radiators (the number depends on the sections);
- Special gaskets to install them between sections.
- Side plugs with gaskets.
So, before adding a heating battery from cast iron, you will need to remove it and disassemble. Do not forget to block water before that!
If the batteries are not new, then a growth of rust and dirt may appear between the sections. To put on the gasket and connect the sections of the batteries, such a growth will need to be removed. This is done either with sandpaper or a metal brush.
Before building a heating radiator, you need to lay out our battery on the floor and additional sections.

When you fasten the nipple, then monitor what position the thread is. We begin to twist the nipple on the left, at first it is best to make it about 1 round on the left of the heating radiator. We also act with the right side.
It is imperative to ensure that the intersecination gasket is located only in the middle of the nipple. Radiator sections should fit tightly to the nipple. Now we insert the radiator key into the radiator, and screw the nipple in the radiator section with the divorce key.
To make a high-quality increase in heating batteries, you need to tighten the nipple into three or four turns, go to the other side of the sections. In turn, we will delay the sections until they fit one to the other very tightly.
Now it’s time to put special side corps for radiators from cast iron. Do not also forget about gaskets from special material. Paronite. If on the surface on which the laying is supposed to be, there will be rust, it must also be cleaned with sandpaper. And only now you can put a cork. Traffic jams need to be tightly tightened, using a piping key.
Who should change and install batteries in the apartment
The owner of the dwelling chooses 1 of 3 options:
Is it possible to do it yourself
Some of the tenants are dismantling and replacing heating radiators in the apartment with their own hands, which in the future is able to provoke thermal unbalance in the home, the creation of emergency situations.
It will not be possible to increase the coverage or number of heating devices without the official permission of the service company. The organization may impose a ban on the installation of radiators in the dwelling in the mismatch of the installed devices. Therefore, before replacing the batteries, residents coordinate the installation with the housing office.
Can Your Entire House Run On Batteries?
Combining heating radiators to each other is not an end in itself of the entire alteration of the heating system. The quality and efficiency of water heating is affected by a large number of factors, it is quite difficult to anticipate all problems. Therefore, it always makes sense to ask the opinion of masters and professionals who do not work in the housing office or the management company at home.
