How to repair radiators in an apartment?

Common causes of radiator malfunctions

Incorrect model selection. The choice of the type of battery depends on the diameter of the pipes, pressure and temperature of the coolant. Repair of heating radiators can be the result of an incorrect connection to the pipes. If a large amount of chemical impurities are present in the coolant or pressure drops occur too often, the metal of the battery corrodes. Low-quality water contributes to the formation of plaque at the joints of the radiator sections, and also clogs the pipes, which entails the need for cleaning. Repair of heating batteries is often necessary due to the destruction of threaded nipples

To prevent the leak from catching you by surprise, it is important to systematically change the gaskets. Battery noise - if you hear clicking sounds, this does not always indicate a malfunction. However, it is better to call a team of plumbers who will carry out soundproofing. Air pockets are caused by low pressure or leaking pipes. Due to scale in the boiler and a leak at the junction of the pipes, pressure drops.

Summing up small results

In conclusion, we can say that most likely you will personally have to pay for the replacement or repair of the radiator while calling the master, of whom there are quite a few in Moscow! They are the ones who will easily repair the battery! There is a small chance that the company will change your battery for free, but this is just a possibility.

But in general, the process of replacing and repairing a heating radiator is a completely simple process. To do this, you just need to understand the characteristics of the radiators and the system itself at a basic level!

Do not forget, before you start fixing the problem yourself, it is best to read the step-by-step instructions, and most importantly, take your time! Prepare all the necessary parts, tools, knowledge and go!

Preparation for disassembly

At this stage, you need to prepare all the necessary tools and dismantle the battery from the attachment point. For work, depending on the type and condition of the radiator, you may need the following tools:

  • radiator (nipple) key;
  • an adjustable wrench or a set of wrenches with different head sizes;
  • autogen or grinder;
  • construction hair dryer;
  • hammer, sledgehammer;
  • chisel.

Disassembly tools for radiators

The nipple wrench is an iron rod with a spatula-shaped head at one end and a hole or curved "ear" at the other. The tool purchased from the store has serifs, the distance between which is equal to the width of the heating radiator sections. They will help you find the location of the desired nipple nut.

Radiator repair

After preparing the tools, it is necessary to equip a place for disassembling the radiator. A floor or a sturdy table will do. It should be borne in mind that dirty water will flow out of the battery, and do not forget to put a waterproof cloth under it.

Features of the installation of heating radiators

According to the industry SNiP, it is necessary to adhere to the following standards:

  • between the battery and the floor, you need to maintain a distance of 10 cm, between the heater and the window sill - from 5 cm, to the nearest wall - 3-5 cm;
  • the length of the device fixed under the window should be no more than 50-75% of the width of the opening;
  • the vertical axis of the battery (it is determined by eye in the middle) should continue the same parameter of the window. Here, a deviation of no more than 2 cm is possible;
  • installation of radiators is most advisable in areas where intensive air circulation is manifested - near doorways, under windows.

If you apply a heat-reflecting screen to the wall (in particular, attach foil material), the battery can be positioned closer - at a distance of 2.5 cm. An additional finishing layer helps to reflect heat from the wall, which leads to energy savings and faster heating of the room.

The assembly technology is determined by the type of operating system and the selected equipment connection scheme.

Wake up sleeping lithium-ion battery

Lithium-ion batteries contain a protective circuit that protects the battery from over-discharge accidents. The transition to sleep mode can occur when the lithium-ion packaging is stored in a discharged state for any period of time when the self-discharge gradually depletes the remaining charge. Depending on the manufacturer, the Li-ion protection circuit is disconnected between 2.2 and 2.9 V, and you need to know how to repair the laptop battery in this case.

Radiator repair

Some chargers have a wake-up or “boost” function to re-enable and recharge batteries that have “fallen asleep”. Without this provision, the charger renders them unusable.

Boost applies a small charging current to activate the protection circuit. If the correct cell voltage can be reached, the charger starts normal charging. If storage of lithium-ion batteries presents a clear uncertainty, then manufacturers recommend keeping them in a state of charge of 40-50%. But at the same time, they warn about the possible loss of the device due to excessive discharge. There is a wide range of action between these criteria, and if the user is in doubt, it is better to store the battery with a higher charge and in a cool place.

How to properly assemble sections of heating radiators: installation and connection

Before you start assembling the system, you need to choose the optimal connection scheme - lateral, diagonal, hidden - depending on the needs and operating conditions.

Connection diagrams

3 solutions are used:

  • side (one-sided) installation. Here, the pipe through which the hot coolant moves is fed to the upper radiator pipe, the lower pipe is designed to be connected to the water drainage pipe. With proper installation, the model exhibits high heat transfer, if you connect the pipelines on the contrary, the energy efficiency of the equipment is significantly reduced. Connecting batteries to a one-pipe system requires the installation of an auxiliary jumper;
  • when connected diagonally, the upper and lower pipes are located on opposite sides of the radiator. The pipe with the hot coolant is also supplied to the upper connecting element, the outlet for the cooled one - to the lower one. This scheme is suitable for long batteries assembled from a large number of sections, it guarantees high heat transfer;
  • the bottom connection allows you to hide heating pipes in the floor or wall, direct and reverse flows are arranged in the lower part of the device from different sides.

The latter option attracts with its aesthetics, but it is not effective enough due to high heat losses - up to 15%.

DIY HP laptop battery repair

Laptop batteries are made up of lithium cells called 18650 cells. They do not last forever and have a lifespan of about 2 years. If the laptop is fully charged but does not even charge for half an hour, then the cells inside the battery are dead.

Radiator repair

With your old laptop battery in stock, some wires and tools like a wire cutter and electrical tape, you can start rebuilding your laptop battery yourself:

  • Open the old battery and take out 6 cells, which are in parallel connection 2 x 2.
  • Check the voltage with a multimeter of your own battery. Typically, a battery voltage less than 3.6 volts indicates that they need urgent replacement.
  • Using one wire, connect all cells in series. The circuit should provide about 12 volts.
  • Open the original block, remove the faulty cells and, keeping the circuit, replace them with working cells.
  • Collect the circuit on your own battery. The battery pack will also have 4 wires - 1 negative and 3 positive (one attaches to the end and two between the battery pack).
  • Check the circuit with a multimeter before closing the unit.
  • Close the battery case, insert into PC and start charging.

Selection of heating devices

In the heating system of residential premises, radiators of several types are widely used.

Not so long ago, cast-iron radiators for the centralized heat supply system were constantly used in housing, and many residents still have them and are waiting for replacement. Such radiators have many different models, which makes it possible to select them for any room. But, unfortunately, their massiveness and very heavy weight often repel buyers. Although in terms of heat transfer and heat storage in the event of an accidental heating shutdown, they occupy a leading position.

If we take devices that meet modern requirements, then, perhaps, radiators made of aluminum and steel can be attributed to this number:

  • the manufacture of aluminum batteries is carried out from high quality and durable materials. Their efficiency is proven by their high heat dissipation. They can be placed in any interior in any room design solutions. The devices have a long service life;
  • the use of steel radiators is mainly used in private houses. Due to the low thermal inertia, it is possible to regulate the temperature in the living area.

If the equipment is outdated and its service life has already expired, it is better to completely replace it with a new one. This will improve heating capacity, reduce costs and risks of accidental emergencies.

Safe removal

Before disassembling, make sure the laptop battery is completely discharged. Once the charge is completely depleted, you need to double check the laptop before removing the battery

It is important!

Radiator repair

Do-it-yourself Asus laptop battery repair procedure:

Open the battery case

To do this, carefully unpack it using a flat screwdriver and a utility knife. After the battery case is open, you can analyze the type of batteries required and learn the wiring diagram for installing them.

Before disassembling, it is better to take a picture or draw a diagram of the connection of the elements, so as not to forget before restoring it It is also important to take all measures when opening to prevent deformation or damage of the plastic case of the battery. Replacing Cells Use a voltmeter to make sure old cells are fully discharged before removing them. This will prevent possible electrical shock. Use the model number on the battery to find the correct replacement cells. Solder the new cells to the wires, making sure they connect to the correct wires. Protective goggles are used when replacing lithium-ion cells. They are handled with care as they explode. Once the battery case is closed and placed back in the laptop, it needs to be fully charged.

Dismantling the cast iron battery

At first glance, disassembling a cast-iron battery with your own hands is quite simple, but it is not. So, first you need to heat the plugs on the battery, for this I use a blowtorch. After the plugs are heated, they can be unscrewed much easier than without heating. (See also: Cast iron heating radiators)

With the help of a grinder, the battery is cut very carefully between the sections. After cutting, the radiator sections are disconnected

In cast iron batteries there is a nipple that must be carefully knocked out of the battery using a chisel. This is required if you decide to clean the radiator or replace a separate section.

With a complete replacement of the radiator, it is naturally not necessary to clean anything. It is enough to cut it with a grinder and take it out.

Radiator repair

The nipple must be removed so that the thread is not damaged. It is subsequently thoroughly cleaned of rust. Further, the grouping and collection of individual sections is carried out. In order for the battery to have good tightness between the sections, you need to install gaskets and coat all joints with silicone. A little later, when everything is dry, the battery can be gently rinsed using a hose.

The design and principle of operation of cast iron radiators

The radiators are of sectional design. In appearance, the sections resemble metal columns, inside which channels for the coolant are provided. These elements are connected to each other using a nipple system. The joints are sealed with paronite or rubber gaskets. The height of the devices is 350-1500 mm, the depth reaches 65-500 mm. The power of the radiators depends on the number of sections and the heat transfer area. In rooms, cast iron batteries are placed under window sills. Usually wall mounts are brackets, but there are floor models with legs.

Depending on the model, cast iron radiators have a power of 100-300 watts. Approximately 25-35% of heat is transferred using radiation (radiation), some - convectively. Thanks to radiation, the heating is better: the radiator heats objects, and not just air. Warm air layers rise upward, and radiation provides heating to the lower part of the room. This creates the most comfortable temperature regime.

How to determine if a radiator needs to be repaired

Signs of poor performance of the heating battery are obvious:

  • the house has become colder, despite the fact that the boiler is operating at full capacity;
  • the apartment is cold, and the neighbors are warm;
  • the radiator is barely warm, and the pipes are hot;
  • the top or bottom of the battery is colder.

Over time, any battery can crack and leak - the masters will eliminate this problem as well. Repairing radiators in Moscow will cost you no more than in any other city in the Moscow region.

Joint repair

To carry out repairs you will need:

  • special radiator key;
  • gas wrench No. 2 or No. 3.

Radiator repair

We will assume that the radiator is removed. It must be laid on a flat surface. Then the plugs and fittings (plugs with holes for pipes) are removed using a gas wrench.

The radiator sections are interconnected by nipples. It is a short cast iron pipe with an external pipe thread (half right, half left) and an internal hole that has two projections.

It is these protrusions that are the place where the edges of the radiator key will abut. In fact, these are stops.

At this stage, you will need an assistant who will fix the heating device in a stationary position. The key is inserted into the hole of the section so that the edges of the tool rest against the protrusions of the nipple. Now you need to turn the key with effort at least a quarter of a turn.

Radiator repair

The thing is that the long-term operation of cast-iron batteries, where a coolant with a high temperature is used, creates conditions under which the nipple and the section of the device are soldered together. The result is a monolith.

Therefore, great efforts will have to be made to break these ties. As soon as the nipple moves slightly off dead center, move to the second parallel element. It is impossible to untwist the sections on one side only, a skew will occur, which will complicate subsequent operations.

Radiator repair

In this way, all sections are disassembled. Now you need to clean the joint surfaces with an iron brush and sandpaper.Only the rust needs to be removed.

Be sure to inspect the nipples, if their condition is in doubt, then it is better to replace them with new ones.

Pay particular attention to the threads

It is best to flush the battery sections at this stage. A hose jet and a pin (wood or metal) will do the job perfectly.

After that, you can proceed to the assembly, having previously prepared the gaskets. They can be made independently from heat-resistant paranite or rubber 1 mm thick. Currently, craftsmen suggest using a silicone sealant that can withstand high temperatures.

Radiator repair

The battery is assembled in reverse order. Be careful when tightening the nipples

Here it is important not to twist, so as not to squeeze the gasket to a critical rate. She just might tear

As with disassembly, the two nipples must be screwed in alternately.

Situations often occur when the stops inside the nipple become covered with rust under the influence of long contact with the coolant. And under pressure from the radiator key, these stops are cut off. What to do in this case, because the sections simply cannot be promoted. Option one is to break the section on which the fistula appeared.

Radiator repair

This can be done in two ways:

  1. Simply smash the battery section with a sledgehammer. Do this carefully so as not to break the good elements.
  2. Can be cut with a grinder. But the junction will still have to be smashed with a hammer.

How to assemble an aluminum radiator

Putting it up in reverse order. We place the sections on a flat surface (a table of a suitable size or simply place it on the floor). If the radiator is not new, we unscrew the end cap and the Mayevsky tap.

Before installation, the threads and grooves should be well examined, they must be of high quality, without chips and drops. On the section to be mounted for the sample, we "drive" the thread by screwing in-unscrewing the nipple

Here you need to pay attention to the fact that a gasket may be located in front of the thread under a layer of factory paint. Rub lightly the end with fine sandpaper, if it is found there, then it must be carefully cut off with a knife with a sharp blade

Radiator repair

This is how an aluminum radiator looks like a cutaway.

Before adding sections of the heating radiator, be sure to clean the ends to a smooth surface. We even remove the factory paint. At the ends of the radiators, it is not needed, but will only contribute to the early manifestation of leaks. Sooner or later, coolant will begin to seep under the paint. In the case of non-freezing liquids, this will happen very soon, if water is used in the system, then not very much, but it will certainly happen. And then the coolant will begin to leak between the sections, although the gaskets are still in perfect condition. And the whole point is that the paint at the ends has exfoliated or corroded, microcracks have appeared. So be sure to clean the ends to a clean metal, but use fine sandpaper to make the metal surface smooth and scratch-free. This ensures that the system operates without leaks in the radiators.

For better tightness, the ends then need to be degreased (you can use gasoline). The gaskets are also degreased, but they must be washed with ordinary soapy water. For a system that will be filled with water, degreasing is an optional procedure, and for systems that will operate on antifreezes, it must be carried out. Antifreeze is very fluid and seeps into the smallest pores. After everything is dry, we begin to collect aluminum radiators.

Then we bait both nipple-nuts by half a turn. On top of the nipple, heat-resistant paronite (silicone) gaskets are put on to seal the joints. Now we take the section that needs to be screwed and put it tightly on the nuts, checking the tightness of their fit. Next, insert the key into the upper hole and twist it 1-2 turns. In this case, we do not use the lever yet.We twist our hands. Then we do the same operation in the lower hole. We repeat several times, alternately tightening both nuts for several turns.

Radiator repair

Unscrew the sections gradually, one or two turns of the nut, then from the bottom, then from the top

We twist as much as we have enough strength. Only after hand tightening can the lever be used. This must be done in two steps on each nipple. It is better not to apply excessive efforts during the final tightening of the nipples, since you can easily break the thread: aluminum is a soft metal, do not forget.

If the section is completely assembled, we screw the plug onto the unused holes on one side, and on the other - the Mayevsky valve (to release air from the system). Now you know how to assemble sections of a heating radiator and, if necessary, you can expand several sections.

There are many batteries, but the assembly method is one

We would like to remind you that batteries can be of several types according to materials:

  • Cast iron;
  • Bimetallic;
  • Aluminum;
  • Steel.

And several types of designs:

  • Panel;
  • Sectional.

For your information! The secret is simple: the method of assembling various radiators is the same + the method of strapping radiators is also the same. Therefore, today's material is universal for all types of batteries.

Let's start with the sections

Let's carry out the assembly using the example of sectional batteries. In order to somehow supplement the information, we will analyze the moments of tying radiators, especially since they are of the same type for sectional and panel heaters.

We put everything in its place.

The binding starts with the distribution of roles:

  1. Each radiator, regardless of type, has four threaded inlets. Our task is to decide on the circuit of the input-output of the coolant for the correct placement of the plugs and the competent connection of the element to the network;

Assembly diagram.

Advice! If you are making a conventional radiator replacement, then you don't need to come up with anything. You do everything in the same way as the previous radiator. Upper entrance, lower exit. The opposite upper threaded hole is a through plug with a Mayevsky tap. The opposite bottom threaded outlet is a blind plug.

  1. Roles are assigned. We assemble:
  • The beginning is the connection of the Mayevsky crane and the blind plug. For these purposes, flax fiber and a special paste for sealing threaded connections are suitable;
  • The fiber is wound in straight strands without lumps and ridges in the direction opposite to the direction of the thread of the plugs;

For additional sealing of the parts, we use fiber.

  • Then the paste fixes this fiber in place;
  • Using a wrench, the plugs are installed in place.

An adjustable wrench is a great helper.

Advice! On sale there are special keys with shaped recesses for the main parameters of the mounting kit. An adjustable wrench is quite enough for strapping the radiator, although its capabilities will not be enough for plugs for cast-iron radiators. Then you still need a gas wrench.

  • Slightly more difficult with water inlet and drainage. Today, the batteries are equipped with taps, called by the Americans, these connections with a union nut provide the most reliable connection. Their installation is as follows:
  • The threaded part entering the radiator is formed in the same way as already described - with fiber and paste;

Recommendations! Flax and pasta can be replaced with FUM tape, as many advise. Indeed it is possible, but it must be done correctly. Such a replacement is possible in houses and apartments where there is an autonomous heating system, where the coolant pressure in the network is low enough - the circuit is closed. FUM tape feels very comfortable in such conditions. With pressure surges, frequent guests of the general heat supply system, the tape can collapse. The result is clear - to flow.

  • The American woman is twisted not with an ordinary gas wrench, but with a hexagon.

Is the replacement possible?

Advice! In many videos you can see how an American woman is screwed in with a chisel, a square pin, and even one grip from a plier. We will not judge how justified this is, but the native key is still better.

Connecting sections

To do this, we need nipples - special section connectors with a sealing rubber ring, as well as wrenches for tightening the nipples.

Our help! A nipple is a type of connection represented by a pipe segment with a central transverse groove for a rubber seal. Ridges with thread for the right and left sides extend from the furrow. This design allows the connector to be screwed into the threaded sockets while simultaneously bringing the radiator fins towards each other.

How to assemble heating radiator sections?

The assembly algorithm is simple:

  • Assembling sections of aluminum radiators, as well as assembling bimetallic heating radiators with your own hands, begins with "baiting" the nipples in the threaded holes;

Photo of a nipple with a seal.

Advice! If you are connecting two sections, then the docking windows must have: one - right-hand thread, the other - left-hand thread.

  • The assembly of aluminum heating radiators, as well as the assembly of cast-iron heating radiators with your own hands, is carried out by uniformly tightening the threaded connections of the nipple and sections using special keys;

Keys for assembling ribs.

Observation! It is better to carry out work on installing batteries together. It is both easier and easier to control the connection.

  • After joining the required number of sections, the assembly of an aluminum radiator, like any other, is carried out according to the strapping scheme, which has already been described.

A few words about the mount

We have already described how to assemble bimetallic radiators, how to assemble an aluminum radiator. The type of constructor is unimportant, the assembly of the ribs occurs according to a similar principle with your own hands. And here it is also better to work together.

Advice! If you are changing, for example, a cast-iron radiator to a steel panel one, then the types of fasteners for cast-iron structures will not suit you. They must be removed and new ones installed. Fortunately, they are in the sets of panel heaters. And while one person will carry out a rough docking, the second can mark the places of future fastenings.

All that is good for sections is not good for panels.

In the piggy bank. If you do not connect the batteries to the riser, but connect to an autonomous system, then the masters advise to make a slight tilt of the battery about 5 degrees so that the Mayevsky tap is slightly higher than the inlet connection with the coolant supply. The result of such a connection is that if air accumulates in the system, it will be at the tap, and not be located above the water flow along the entire perimeter of the pipe.

Disassembling old batteries

The wrench is required to assemble and disassemble the cast iron battery.

To disassemble old cast-iron batteries, since the thread sticks in them, they must be heated at the location of the nipple with an autogen or blowtorch. Heating is done in a circular motion at the location of the nipple, sequentially heating the parallel joints of the battery.

After warming up the joints, while they are hot, a radiator key is inserted inside and about half a turn is made, then the key is quickly rearranged into another nipple.

In the same way, sticky plugs and footwear are turned out of cast-iron batteries.

Sometimes it is impossible to unscrew the nipple, due to the fact that its turnkey protrusions are completely eaten away by corrosion. In this case, the sections at the joints are cut with a hacksaw for metal or a grinder. Then cut nipples are turned out of the sections by heating. Then the thread is cleaned with a metal brush.

If the old heating radiator cannot be untwisted in the above ways, then one thing remains - with the help of a sledgehammer, break part of the sections. To do this, place the battery horizontally on the floor, and hit the middle of the sections with a sledgehammer until a through piece of the section breaks off.Then the battery is turned over to the other side and the other half of the section is broken.

After that, the cast-iron radiator is installed in a vertical position and blows are applied to the remaining pieces of the sections, then they are untwisted. However, when performing this operation, the heating radiator loses its tightness at other joints. And you can lose half the battery.

Dismantling and disassembling cast iron radiators is not an easy process, but sometimes it is necessary, so it is very useful to know how this operation is performed correctly.

Heating radiator designs

If a heating element breaks down, especially in the cold season, it must be repaired or replaced immediately. Whether the radiator can be disassembled depends on the type of its design. Quite often, non-separable types of radiators are installed in apartments, which cannot be restored. In this case, it is best to purchase a new battery right away. But there are also collapsible models that can be dismantled to replace the damaged element and installed back.

Products are divided into two main types:

  1. Sectional batteries assembled from several identical sections, securely connected to each other. Each of them has a channel through which water circulates, and fins that radiate heat heat the room. Sectional batteries are the most popular because the cost of such radiators is lower. In the event of a breakdown, it is enough to replace only the damaged section, and if necessary, you can always add or remove ribs.

Radiator repair

Sectional heating batteries

  1. Monolithic products represent one solid structure, which does not have separate sections. Outwardly, these radiators may resemble sectional counterparts, but the differences between them are obvious. In monolithic devices there are no connecting joints, due to which they are able to withstand more pressure. From this, the terms of failure-free operation of these structures are almost twice as long as those of sectional ones. But in the event of a leak, the monolithic device will have to be changed completely. In sectional products, it will be enough to replace the damaged element.

How to choose a heating radiator?

For apartment buildings, it is for such residential areas that several suitable radiator options have been created. For example, since ancient times, many people have installed cast-iron radiators in their apartments. And at the moment, for many, they still remain and are waiting in the wings. This type of radiator has a lot of models, which allows you to choose them for any type of room.

But there is immediately a drawback, these battery models are very weighty, and not as light as, for example, aluminum ones. It is precisely this disadvantage that repels a fairly large part of buyers, because no one needs heavy radiators. But it also has some advantages.

Starting from a very good level of heat transfer, as well as cast-iron radiators perfectly retain heat for a long time even after an emergency shutdown of the heating system. So what are the best heating appliances to take? Which ones are closer to modern technologies? And this list immediately opens with steel and aluminum radiators:

  1. Aluminum radiators are currently in high demand in apartment buildings. Most interestingly, they are made of durable materials. They also have a very high heat transfer rate. They are also perfectly combined with many interiors of houses, and in size they perfectly fit into any place. Note that this type of radiator has a long service life.
  2. As for radiators made of steel. This type is most often found in private homes. Note an interesting feature, batteries of this type have thermal inertia, due to which you can adjust the temperature.

But what about any kind of radiator in general? Of course, they must be replaced, especially if the equipment is very old. Replacing with a new radiator will make it possible not only not to lose comfort in the house, to increase the heat in your house, but it can also slightly reduce heating costs. The level of emergencies will also decrease.

By the way, as for who should pay for the replacement or repair of the heating system in an apartment building? In theory, the purchase of a radiator and repair is not assigned to the owner of the apartment, but there is one but.

If there is a jumper that separates the general system from the radiator in the apartment, then you don't need to think about free repairs. It turns out that this radiator is already yours personally, and not a radiator of the general heating system.

DIY cast iron radiator repair

Typically, the leak is easily identified. If there are difficulties with diagnostics, the radiator is removed, immersed in a bath of water and monitored for the appearance of air bubbles. The place from which they rise is not airtight. When a leaking area is identified, materials and tools should be prepared:

  • thin metal cable;
  • putty;
  • a piece of cloth;
  • metal clamp or something that can replace it: electrical tape, wire, etc.

Radiator repair

Work order

  1. Cover the floor with oilcloth, put a rag on top to absorb excess moisture.
  2. With a thin cable, clean the leaking section of the radiator to metal, degrease with any solvent or gasoline.
  3. Cover the leak. Apply the putty to a strip of fabric and wrap tightly over the damaged area in several layers. If metal powder or epoxy resin is used as a putty, then 2-3 layers are enough. If zinc white is 4-5. Cold welding is also used as a putty. No fabric is needed for her.
  4. Place a metal clamp on the putty, tighten with bolts and nuts. Make sure that the connection is on the opposite side of the leak. If electrical tape is used instead of a clamp, wind it in several layers and secure with wire.

Radiator repair

Repair of cast iron batteries is not difficult, does not require special knowledge and skills, but if you have doubts about your abilities or a leak is really serious, it is better to contact a specialist. It makes sense to replace old radiators, which have leaked more than once, otherwise their repair will become a constant activity during each heating season.

Renovation work

Every heating device that heats an apartment building needs preventive maintenance and repairs over time. Preventive maintenance of equipment is carried out at the discretion of the owners, but at least once a year. Repair work is carried out when the need arises. The best time to replace outdated or outdated heating devices is during the overhaul of the entire apartment building. In the event of an emergency, replacement is carried out immediately after the occurrence of a breakdown.

In the apartments of multi-storey buildings, it is not uncommon for a need to start performing various types of work. After assessing the condition of the heating system, you can see how much money will need to be invested and how long it will take to repair the required area. According to experts, when repairing the heating system in an apartment, repairs should be carried out in stages.

Here is a rough plan for repairing cast iron batteries:

  • shutting off the water supply to the heating device, it is necessary to drain the coolant;
  • after that, the radiators are removed from the brackets;
  • repair of the heating riser in the apartment;
  • if necessary, flush the insides of the pipes;
  • if there are damages in the shut-off or control and measuring valves, then repair or replace them;
  • installation of heating devices. If necessary, install additional equipment;
  • to carry out pressure testing - test work, which is carried out at the established working pressure;
  • after, the system is checked for operability;
  • the heating system is being painted.

If possible, it is better to postpone such work for the summer period, this approach gives the advantage of combining it with the renovation work of the apartment.
