It is important not to flood the neighbors and not to remain without heat yourself Principles of replacing heating batteries in the apartment
Dismantling heating radiators is required in various situations: before installing new batteries; during the repair of the room; to replace leaking sections; when replacing the bellows due to arising fistulas; to clean the batteries from accumulated deposits.
The way of fixing the heating elements
To dismantle the radiator, you need to determine how it is attached to the overall heating system. The most popular options:
- on the spigots, when the pipes are connected from two parts. a spigot with an extended thread and a lock nut. The heating system can be disassembled, the radiators can be removed and washed or replaced,
- Welding of joints was used when installing convector-type radiators, in the form of a tubular coil. All issues are resolved with the help of an angle grinder. The pipe is simply cut and the battery is dismantled,
- Fitting system, which includes quick-release fittings with sleeved nuts. These fasteners are used when installing the latest batteries. With their help, it is easy to disassemble the pipe connections and remove the radiator.
Sometimes you have to remove the entire heating system, cutting out the old pipes and heating elements.
How to open the radiator in the apartment?
From the author: hello, dear friends! The need to shut off the radiator in an apartment building can arise for completely different reasons, and not only during the heating season. The purpose of this article. to break down the question “How to close the radiator in the apartment?”.
Residents of private homes do not have such a problem due to the autonomy of the heating system. But in an apartment, where the radiator is a part of a multi-level system and is firmly connected to the neighboring heating devices, it is important to follow certain rules. After all, independently closing the radiator can lead to unpleasant consequences.
The need to shut off
Before proceeding to the scheme of disconnecting the battery from the riser in an apartment building, we suggest considering the basic causes that can provoke a failure in the heating system.
Here is a list of the most likely reasons for disconnecting the radiator:
- An emergency situation that can flood your and your neighbor’s apartments with hot water;
- painting radiators in the cold season, when the heating is already on;
- If there is a necessity to change the radiator or to wash it;
- In winter the radiators are too hot and you want to lower the temperature in the room.
In some apartments, residents practice closing the radiators in the summer without draining the coolant in order to save the radiators from clogging during the autumnal turn on the heating system. At this time the water in the pipes often comes with fragments of rust. How to do it correctly, we will tell in a section of this article.
Instructions for Disconnecting
You should not have any problems with turning off the radiator if it is connected to the common system correctly, using ball valves (shut-off valves). In this case you can at any convenient time quickly and “painlessly” shut off the coolant flow without disturbing the thermal regime of the apartments of your neighbors.
Is it possible to shut off the radiator? You can if you follow the steps below in sequence.
- Turn off the taps on the radiator. first the bottom, then the top.
- If you plan to paint the radiator, the first point is enough for you. Just wait until the radiator cools down and start painting it;
- If you shut off the radiator, because you need to replace it, or to repair a fragment of the heating system in winter, then before removing the radiator, you need to depressurize with a Maevsky valve.
Now let’s figure out how to turn on the radiator to avoid the formation of an air lock. In fact, the algorithm is the same: first you need to open the lower valve, then. the upper. The last step is to let the air out, using the Maevsky valve. If you first open the upper valve, and then the lower one, then part of the air will remain inside the radiator section.
How to open a jammed ball valve
It has been observed that if ball valves are not used for their intended purpose for many years, they tend to get stuck due to the formation of scale. Do not use brute force, trying to open the valve with a gas wrench, pliers or pliers. The butterfly valve is made of a fragile alloy, which means that it is guaranteed to crumble from excessive force.
Here’s how to behave if the faucet handle does not yield the first time.
- Unscrew the retaining nut and remove the “butterfly” from the rod.
- Usually in such valves under the “butterfly” there is a nut that fixes the plastic gland. It needs to be loosened.
Tip: If you have WD-40 spray lubricant in your household, you can apply it to the hardened stem and leave it on for 5-10 minutes. This will make it easier to unscrew. In the case of battery maintenance the proverb “Prepare the sledge in the summer and the cart in the winter” could not be more appropriate. If you try to shut off the battery with a faulty ball valve while the heating is on, you may have an emergency situation!
Suppose you didn’t want to follow our advice and tried to forcefully close the battery. As a result, not only the rod is able to break off, but the valve body can burst. From the crack in you under pressure will flow hot coolant, and this is fraught with serious burns. While you run to the basement to shut off the riser in an apartment building, your furniture and interior may be ruined. You may have to make repairs and the neighbors from downstairs. It is better to ask for help from master plumbers, who are qualified and have the right tools.
How to turn off a radiator without a cutoff valve
Let’s assume that your apartment has “Stalinist” cast iron radiators or steel convectors. The design of these devices do not imply the presence of shut-off valves. And it means that to shut off the radiators during the heating season is not possible.
over, the old heating scheme implied the connection of batteries in apartment buildings directly to the risers without bypasses (straight sections).
Here’s how to proceed if your old-style radiator leaks:
- You need to take care of some kind of container into which the water would drain. There are situations where the jet is hitting the side with a strong head. In this case you have to wrap a cloth or a rag around the place where the boiling water flows, so that the water can flow into the basin;
- The heating company in your home should be told what has happened;
- Do not sit idly by while the rescuers of your property go. Take care of access to the basement, find the keys, open the door. so professionals will be easier to solve your problem in the shortest possible time;
- Try to shut off the riser yourself.
On the last point I would like to go into more detail. To turn off the heating riser, you need to go down to the heating point of the entrance. Your target. vertical pipes, which are cut into the main line of large diameter, they can also be part of the total collector.

Next, you need to identify the emergency riser in the apartment building in order to properly shut off exactly it.
After you have turned the valve, call your housemates back and clarify whether the radiator has stopped leaking. If yes. you have coped with the task, if not. open the riser valve (since you seem to have left your neighbors without heat) and continue looking. You need to alternately close all available valves until you find the pipe that is responsible for your dwelling.
Important: If the basement pipes are covered with rust and do not yield, you should not apply force. You have to wait for the arrival of an emergency team. They will figure out if you can shut off the pipe, and find a way to fix the breakage. Otherwise you risk to break a valve of the main pipe and leave without heat not only your apartment but also the whole house!
How to properly shut off the radiators for the summer
We already mentioned at the beginning of the material that in some apartments, owners shut off the radiators in the summer. The purpose of this action is to avoid clogging the radiator with dirt and rust, which is often in the water during the start of the heating season in the fall.
This precaution is especially important for radiators with narrow ducts. aluminum and bimetallic.
Here’s what to do if you decide to turn off the radiators for the summer: turn off the taps on the supply lines to the radiator, as it is unclear whether there will be water in the radiators in the summer.
In most cases, utilities in apartment buildings flush water from the risers and the heating system as a whole, which leads to deterioration of metal due to corrosion.
Tip: It is excellent, if your home installed radiators made of cast iron, such an alloy is not subject to corrosion, and wide passages allow you to avoid clogging.
Let’s look at the sequence of actions when you turn off the radiator for the summer:
- It is important to choose the period when the heating is almost off, but there is still water in the pipes. Taps near the radiator should be shut off, starting with the bottom one;
- In the fall, you should wait for the startup of the heating system. you will hear a characteristic gurgling in the riser;
- wait a few days and make sure the pipes are warm. Next, you should open the valves and use the Mayevsky valve to bleed. By this time the water with impurities will have passed by your apartment on the riser.
Tip: If for some reason you missed the moment and did not have time to empty the heating system, you can still shut off the radiator taps. With the advent of the heating season wait a few days and turn on the radiators.In conclusion, we would like to note that disconnecting the radiators from the riser in an apartment building is a simple procedure if the batteries are equipped with cut-off valves. See you on our website!
The need to turn off
Before proceeding to the scheme of disconnecting the battery from the riser in an apartment building, we suggest considering the basic causes that can provoke a failure in the heating system.
Here is a list of the most likely causes of battery disconnection:
- In an emergency situation which threatens to flood your and your neighbor’s apartments with hot coolant,
- Painting radiators in the cold season, when the heating is already on,
- If the radiator needs to be changed or washed,
- In winter, the radiators are too hot, and you want to lower the temperature in the room.
In some apartments residents practice closing the radiators in the summer without draining the coolant in order to protect radiators from blockages during the period of turning on the heating system in the fall. At this time the water in the pipes often comes with fragments of rust. How to do it properly, we will tell in one of the sections of this article.
Cleaning the radiators in private and apartment buildings
The radiators get clogged inside in any case: whether they are located in a private house or in an apartment building. And how to properly flush heating radiators?
Things with flushing the radiators in an individual living space are much better than if you do this work, having one heating system for all. In your house, everything depends only on the owner of the dwelling.
In an apartment building, you can do this procedure without the services of a plumber. But it is necessary to observe the condition. the risers should not be in a clogged state, because the effect will not be. Flushing should be done before the heating season, when the risers are still without water. It is desirable before it starts, because then the utilities will already do their blowing. After the water supply and its operation, the difference in the degree of heating of your batteries will be felt.
A positive result is guaranteed when the residents of apartments, the heating of which is connected to one riser, agree to flush their radiators all together. In this case, the debris accumulated in the radiators will not have any chance to remain in the system, and this will give the maximum effect of the performed procedure.
We recommend reading the tips on washing envelopes.

How to Wash Cast Iron Radiators?
In this section you will learn how to flush cast iron radiators. These products were in great demand in the past, and now, after many years, most of them are still in place, and in use. From this we can conclude that cast iron radiators are really durable. The disadvantage is the formation of rust and scale inside.
Before you flush the radiators:
- Pre-wash the water from the system;
- pick up the necessary locksmith tools;
- Put a vessel under the radiator into which water will be able to drip after it is disconnected from the system;
- Perform disassembly of the product, removing it from its pins.
The radiator itself can be flushed in a cast-iron tub or outside. To do this, prepare a solution of the product, which will remove scale and rust from the walls. You can use such substances:
- a vehicle radiator flushing agent;
- vinegar essence;
- caustic soda;
- citric acid;
- milk whey.
If you do decide to do the flushing in the bathroom, make sure to protect the drain with a plug with a sieve. Before you begin, remove all the plugs from the battery, and pour in boiling water from the kettle a little at a time from all sides. If possible, the radiator is shaken and the water is poured out. In the used water will already be present particles of scale and rust. Then pour the active solution and wait for 1-3 hours. After this time, the radiator is shaken again and tapped with a wooden hammer. Drain all the contents of the radiator and refill with water. Repeat the water procedure as many times as deemed necessary. If acid was used, it is necessary to try to wash away its residues, so as not to provoke the appearance of rust again.
How to wash properly heating radiators made of aluminum?
How to wash aluminum radiators? The difference in action, of course, there is, but it is not a big one.
The process of removing the radiators is much easier in aluminum radiators, because they are more modern. Aluminum objects are not susceptible to corrosion, and therefore there is no need for tapping, which in addition can deform the products.
Carry out the same actions as with cast iron radiators, only with the specified nuances. In the reverse installation using modern sealants, such as FUM tape.
Be sure to remove radiators when washing them?
And the last question that may arise in readers: how, without removing, to flush heating batteries? If the work is carried out in an individual heating system, and it has a small length, you can supply water, and on the other side it is drained. Since hot water has a more pronounced activity, it is necessary to fill it.
Despite the labor-intensive work, it prolongs the life of the heating system. With regular flushing there may be no need to dismantle it, and the process will be carried out as above.

Types of heating systems
There are 3 categories. one-pipe, two-pipe and manifold, they differ in level of heat supply and specificity of connection of constructive elements.
Types of heating systems
The equipment is combined in a bundle so that the coolant moves only one pipe, consistently passes through each radiator and already cooled enters the boiler. This simple method of installation is widely used in multi-storey houses. The disadvantage of this solution: more and more cooling water passes through each successive radiator, respectively, the rooms are heated worse. There is no possibility of individual repair of one radiator, in an emergency situation will have to turn off the riser.
Thanks to the parallel connection of the batteries, the hot coolant flows to each of them through one pipe separately. The entire complex of equipment is heated evenly, the cooled water flows into a separate return pipe, through which it is transferred to the boiler, where it is reheated. It is also not difficult to assemble the system here, if it is necessary to replace only one radiator needs to be disconnected.
This complex scheme is used for heat supply of cottages: separate pipes must be brought to each radiator. Usually professionals are involved in its installation.
How to remove the radiator in a multi-storey new building by yourself
Most apartments in high-rise new buildings (over 16 floors) are now sold without finishing work. Only with sewage riser, inlet hot, cold water and at best with wiring and switchboard apartment. This allows you to minimize the amount of construction debris when the new owners of the apartment start to make repairs in it, sometimes with a radical redevelopment.
Nevertheless the radiators in such apartments are already installed, and in order to plaster, putty the space behind the radiator, glue wallpaper or do other work such as changing the radiators to more expensive ones, the radiators have to be removed, and to do this you need to cut off the supply and return of hot water.
At first glance, this question is relevant only during the heating season, and in summer there may be no water in the heating system. However, in new buildings there is water in the heating system even in summer. All the same, concealed laying pipes, and if something is wrong, it is better to find out in the summer during the repair than in winter, when the window.30 C, and the floor is already laid expensive Spanish tiles.
Now in high-rise new buildings, as a rule, the heating distribution is done horizontally. Pipes of hot water and return flow are laid under the screed (as well as wiring), and only near the battery itself pipes come out of the floor. Thus you have not only the usual batteries of water heating, but also partially heated floors. Very convenient and very thoughtful. Thus there are no pipes on walls near windows that is obligatory at vertical distributing and pains almost any housewife. That’s just if the pipes in the floor with a marriage or poor-quality joints, the screed will have to break and malfunction to correct (however, this point of repair to the subject of this article does not apply).
In addition, the horizontal distribution of heating allows you to install heat meters for each apartment, which at today’s for energy is very relevant and virtually eliminates quarrels between the neighbors in the riser because of the settings heat meter for the vertical distribution of heating (as damper is not regulated). Some will be cold, others hot).
Heat meters are installed in the distribution center on each floor. And in addition to counters there are taps that allow you to quickly and easily shut off the hot water supply and return flow (or just taps, if the apartment heat meters are not equipped with).
But the fact is that in high-rise new buildings, when the floor is 10-20 apartments, and most of the apartment owners are still engaged in loud repairs, rather than quiet living, to get access to the distribution node. problem. Until the repairs are finished and not all tenants have moved in, there is only one key to the floor junction and it’s usually at the plumber’s. the builder’s representative.
In principle, it’s not a problem to call this plumber. not a problem. Except that he is not at work every day, and in addition he is very busy, and the working day of the plumber is relatively short (it only seems to people, trying to finish repairs in a new apartment as soon as possible, that removing or installing radiators at 10 pm on Sunday. this is normal). But in any case, the services of this plumber-key is usually not free (and if it is free, then there is no point in you continuing to read this article, because the plumber will come and do everything for free).
To remove one radiator, the plumber from the builder will take a couple of or three dollars, and then another as much for connecting each radiator. Thus, for the removal-installation of batteries in a three-room apartment plumber from the builder will have to pay 15-30. An outside plumber can take even more, given the possible transportation costs.
In general, plumbers don’t like small jobs. Spend half a day standing in traffic so they can make 10-15 dollars for 5 minutes. willing to a little, so the replacement of a penny gasket in the old cheap faucet and scouring siphon and install a new expensive toilet (and that at least drilling holes for mounting the bowl to the floor, fixing the toilet bowl to the floor, installing the tank, connect to an existing plumbing and drain valve, adjustment of the inlet and outlet valve) have to pay 20-30. A lot more interest from plumbers to larger orders such as razvodka plumbing and sewage in the apartment, when the work should pay 200-500. Such work is done in 1-2 days, so you can stand in traffic jams.
But even if you yourself will remove and put the battery, or it will do outsourced plumber, it is still for turning off the water and return flow on the floor (if the battery is not equipped with taps), the plumber will take the same 2-3, and then another as much for the inclusion of water.
If it is in the winter, you have to remove and install each battery a few times, as plastering, puttying and gluing wallpaper for 2 hours is not done. And to heat the repaired room with electric heaters. Can come out even more expensive than calling a plumber every time. As a result, paying for the relatively simple removal-installation of batteries in a three-room apartment can cost 50-100.
Meanwhile, you can save on these relatively small, but still unplanned costs, if each radiator is equipped with taps, and they are usually installed with a hidden horizontal distribution. You can do it quickly and easily enough, at any convenient for you time, even at 3 am, besides, almost for free, it requires a couple of keys, a minute of time, and of course, the knowledge of how to do it.
Almost free because if I just tell you in this article how to do it yourself, some plumbers will lose some of their already modest income. In particular, this will happen to an old plumber acquaintance of mine whom I often meet for a mug of beer and a chat about life. However, he speaks mostly complaining about the unfair structure of life and the fall in income in recent years. He is the one who told me this story about the batteries.
In this regard, I decided to make this information payable. The fee is small. 1.5 in the local equivalent (100 or 50 hryvnia). As practice shows, paying money for information. of the willing few. Many people think you can get any information for free. And even for information that can save more than a hundred and sometimes a thousand dollars, not everyone is willing to pay 10, not to mention larger sums. So if I earn a month for a couple of beers for my friend, it will already be good, and a possible decrease in customers for 1 person a year, and he will not notice.

Disassembly of aluminum and bimetallic radiator
Before you disassemble the radiator, prepare the necessary tools.
The main tool used is a nipple wrench (can be rented from a specialized store for small money). It is a bar with a length of about 700 mm. On one side, the head of the wrench is welded to it with a size of 24×40 mm, and on the other side is a through hole. You can insert the metal rod into it. With it, it will be easier to twist the nut.
This is the main tool used when assembling / disassembling heating radiators
There are several notches on the surface of the wrench. The distance between them corresponds to the width of the radiator section. Inserting the wrench inside the battery, and counting the number of notches, you can easily find the nipple of the desired section.
Before you disassemble the radiator, you need to orientate with the direction of the wrench. Place the radiator on a flat, horizontal surface with the side facing up. On the right side there is right-hand thread, and on the left-hand side. left-hand thread. To avoid confusion, you can do something simpler: take a nut and press it alternately on the right and left, and then conclude which way to turn the wrench. This is important because the threads can easily be torn and then you need to buy two new sections. On the front side of the section on the plugs and small plugs foreign manufacturers make the following thread designations: D-right, S-left.
The thread on the nipple nut can be right or left, so before you disassemble the radiator, determine which way you need to twist
Let’s say you need to unscrew one section to the right. To do this, the key “spatula” is inserted into the upper hole to the right place, secured in the groove nipple nut and with force turn the key counterclockwise to “tear off” the place. Here we need the rod inserted into the ring on the key: it requires some effort.
Make two full turns and move the wrench to the bottom of the radiator. Repeat the operation by turning the key in the same direction. Unscrew 2 turns of the nipple and here. Again we take out the key and repeat the procedure for the upper part. Then one by one unscrew the whole section. To make sure there are no misalignments.
Assembling the cast iron heating radiator
Before you reassemble the first thing you must do is to clean all the sections threads from the traces of packing material and jute. You can use a metal brush, kerosene and a rag for this.
The thread quality must be checked by screwing in new nipples and plugs. The order of assembly is shown in the diagram.
Before assembly, each cup is treated with Ciatim or graphite, wrapped in burlap and screwed into the body of the register by one thread.
Assembly only on the table
On top of the sealing ring is installed, the next register of the battery and aligned on the axis. After that you can wrench. If the threads “don’t go”, it is better to disassemble and try to determine the cause. Assemble with minimum force.
