How to clean a heating radiator. Do-it-yourself washing of heating batteries

Here you will learn how to wash an aluminum heating radiator in an apartment: the need for the procedure, whether it is possible to clean the batteries with citric acid, as well as hydrodynamic, pulse and hydraulic cleaning.

Whatever the pipes and radiators are made of, they need to be cleaned periodically.

This is caused by the quality of the coolant, which leaves behind particles of suspensions and debris that tend to settle on the walls of the radiators, gradually narrowing their internal space.

Flushing of aluminum heating radiators should be carried out every 5 years to extend the service life of the structures.

Necessity for the procedure

There are a number of signs that indicate that radiators need cleaning:

1. If they are heated unevenly, for example, up to half of them are hot, and the second part is cold.
2. When the radiator takes longer to warm up than before.
3. Flushing an aluminum radiator is necessary when the energy consumption for its full operation has become noticeably higher.

These are the main symptoms that an aluminum radiator needs to be flushed. In an apartment with a centralized type of heating, this is a necessity, while in autonomous systems such a problem as contamination is less common. This is due to the fact that the length of the pipes in the first one is much longer and the coolant passes through it, collecting all the debris along the way, while the second one can be filled with filtered water, which will completely deprive the batteries of contamination.

Most often you can “find” inside the radiator:

Flushing of radiators should be carried out at intervals of 3-5 years with central heating and 5-7 years with autonomous heating, but pollution prevention is carried out annually.

This is due to the fact that just 1 mm of deposits reduces the efficiency of the structure by up to 15%, which, in turn, entails an increase in costs during its operation.

Today there are 3 ways to flush heating systems:

1. Chemically.
2. Hydraulically.
3. Impulse.

They all have their advantages and disadvantages, so it’s worth familiarizing yourself with each one before choosing how to flush an aluminum radiator.

How to clean an aluminum radiator?

Use of chemicals

Aluminum is an extremely capricious metal. When choosing what and how to rinse aluminum radiators, you need to focus exclusively on the product whose composition will affect the deposits without affecting the walls themselves.

Chemical washing is good because it does not require dismantling the batteries and can be carried out even at the height of the heating season.

It is based on 2 stages of work:

1. Dissolving scale.
2. Flushing and removing them from the system.

The disadvantages of this type of cleaning include the increased toxicity of chemicals. When carrying out this, you need to use protective measures and be very careful. Attention is also required when diluting a chemical composition if it is sold as a concentrate. An incorrect proportion can destroy aluminum along with scale.

The most popular is the Master Boiler Power concentrate, which is suitable for all types of pipes and radiators. You can also use “folk” remedies, for example, vinegar, whey or caustic soda.

Hydrodynamic flushing

This is one of the most labor-intensive ways to clean a heating system. It is based on a shock jet of water, under the pressure of which the scale peels off the walls of the radiator.

Sequence of work:

1. The carrier is completely drained from the line.
2. Areas that need to be washed are identified.
3. Part of the pipe is removed, and in its place a hose with a special nozzle is connected, the end of which is inserted into the main line.
4. Water under the action of a pump under high pressure is supplied to the radiator, sweeping away scale and all debris along the way.

After the cleaning is completed, the system should be filled with water and run through it several times to remove scale removed from the walls of the radiator.

Hydraulic flushing

This work can be carried out during the heating season, since it only requires running water through the system:

1. Before starting work, a hose is connected to the drain valve, the second end of which is discharged into the drainage sewer system.
2. The tap on the supply side opens and the layer of dirt disappears under the flow of incoming water.
3. Cleaning can be considered complete once clean water flows through the system.

This method is used for regular cleaning of batteries. If the system has not been cleaned for a long time and the contamination is strong enough, it will not help.

Pulse washing

If the question is asked how to clean an aluminum heating radiator with minimal risk to it, then the answer is clear - using pulse washing.

This is a fairly “young” and progressive method that guarantees safety for the aluminum walls of heaters, but it requires special devices, so calling in specialists is indispensable.

The method is based on a short-term pulse effect on water, during which a shock wave is formed that moves through the system under a pressure of 12 atmospheres. This allows you to remove scale of any thickness without damaging the walls of the radiator, provided that it can withstand such water hammer.

This method is effective if:

1. The diameter of the pipes does not exceed 4 inches.
2. Even 60 m away from the device that creates the pulse effect, radiators are effectively cleaned of scale.
3. Pulses do not affect the integrity of fittings and line components.

This flushing method increases the efficiency of the radiator by up to 25%, which practically returns the design to the parameters corresponding to the product that has just left the factory assembly line.

Cleaning batteries in the apartment

Consumers often wonder how to clean an aluminum heating radiator in an apartment with their own hands. This is not difficult to do, but only after the end of the heating season.

This is due to the stages of work:

1. All media is drained from the heating main.
2. Radiators are dismantled.
3. If the batteries are very clogged, you will have to disassemble them into separate sections; otherwise, it is enough to wash them with a chemical, filling the internal space with it and keeping it inside for an hour.
4. Rinse the radiator with running water under pressure to remove scale and chemical residues, after which it can be returned to its place.

This procedure requires careful handling of the aluminum radiator so as not to cause mechanical damage to its outer walls, for which the bathroom is covered with thick rags.

As a rule, aluminum reacts well to acids and negatively to alkalis, so when asked whether it is possible to flush an aluminum radiator with citric acid, the answer will be positive. The only thing that should be taken into account is the amount of substance for cleaning efficiency and the time the solution remains in the system. As a rule, ready-made products are more effective, since they are already diluted to the desired consistency with an indication of the duration of the process.

Flushing aluminum radiators is a prerequisite for the efficiency and durability of their operation. The choice of how to do this remains with the consumer, but in order not to harm the system, it is better to entrust such delicate work to professionals.

In order for the radiators to work properly, the heating to be maximum, and the heat to quickly spread throughout the room, the heating radiators need to be flushed. New and old radiators made of any material can be washed, but not every cleaning method is safe for health. Let's look at how and how to clean appliances from the inside and outside, and we'll understand the rules and frequency of cleaning.

In order for the coolant to flow through all sections, it should not be interfered with by various mechanical inclusions, including rust and dirt. Slag settles at the bottom of the collector, so the top collector may be hot and the bottom of the battery cold.

Cleaning heating radiators is necessary when the following signs of slag accumulation are detected:

• the coolant supply pipe is heated and the battery is cold;
• there is clearly a lack of heat in the room, despite the fact that the neighboring room or apartment is heated sufficiently;
• uneven heating of radiator sections, the last elements can be very cold;
• Batteries take longer to warm up;
• gas and electricity consumption increases, depending on the type of boiler.

In addition to the accumulation of debris, such signs can be explained by the formation of air locks, poor adjustment or reduced pressure in the system. Before flushing the radiators, you should make sure that the problem lies in the heating source itself - the problem may be outside the apartment or house. For example, a boiler or thermal power plant failed.

Types of material

Before washing heating batteries, you should determine the material from which they are made:

1. Aluminum appliances cannot be cleaned like copper-brass and cast iron appliances. Due to the lack of solder in the structure, aluminum does not respond well to cleaning with caustic soda. Flushing aluminum radiators is only required if the refrigerant is changed irregularly.
2. Radiators made of cast iron and copper-brass alloy can be cleaned using any available means and methods.

Disassembly of the structure

Cleaning cast iron batteries is associated with certain difficulties, but if you do the procedure yourself, you can save a lot of money. You should be prepared for the fact that the entire system will not be washed; after some time, the accumulation of slag will form again and the help of a specialist will be required. But if everything is done correctly, the risk of debris accumulation will be minimal.

How to clean radiators at home:

1. Turn off the heating and leave the system to cool for several hours. This is necessary to prevent burns from the coolant.
2. Place basins under the heating radiator and spread out rags so that dirty water can drain and be absorbed without spoiling the finish.
3. Turn the valves at both ends of the device. The thermostatic valve can be turned by hand, but a key may be required to unscrew the locking device with a removable plastic cover.

Important! You should record the number of turns of the key so that you can then close the valves by the same number of turns.

1. Remove the valve and connecting nuts of the thermal valve to the radiator. Open the outlet device - coolant can immediately flow out, so it is important to work carefully.
2. Move the battery outside to the bathroom. The device is heavy, so help will be needed. If washing cast iron batteries is carried out in the bathroom, you need to place a rag on the bottom, otherwise the radiator may leave chips and marks.

The dismantling process is over, let's look at the stages of cleaning appliances made of cast iron and aluminum.

Cleaning the interior

The operating algorithm is as follows: insert a hot water hose into the valve outlet, rinse the battery with a high jet pressure to remove slag. If plain water does not help, then the batteries are washed with additional chemical components. The end fittings should be replaced, concentrated acetic acid heated to +40 C should be poured into the sections. Leave the solution for 3-4 hours to ensure better cleaning, then drain the liquid and rinse the radiators again under pressure.

Advice! Cast iron batteries can be washed with vinegar several times, always alternating the composition with plain water under pressure.

A means for removing debris and slag is made from an acid or alkali (vinegar, caustic soda). Caustic compounds quickly cleanse contaminants. But if vinegar is not an option, then you should look for something to clean an aluminum radiator with. A suitable composition for cleaning car radiators. This is not an aggressive, but a soft liquid, which is poured inside the sections, then the required volume of water is added according to the instructions on the package. The liquid composition should fill more than half of the internal space of the heating device. After filling, the battery must be shaken every 10 minutes for two hours, and then rinsed with a hose using a strong stream of clean water.

The composition is prepared from caustic soda as follows:

• mix part of the soda with a slightly smaller part of the washing powder;
• add water to obtain a concentrated liquid solution;
• pour the mixture into the radiator;
• Shake the battery as hard as possible and leave for an hour.

Then rinse the radiator with powerful water pressure, removing not only slag, but also deposits and rust. The soda solution smoothes out internal roughness on the walls of sections and reduces the rate of scale formation. Regularity of use – no more than 1 time per month.

On a note! Cleaning products Mole, Antiscale, and whey help well.

Removing radiators is a complex process and not always feasible. Let's consider whether it is possible to wash old batteries in an apartment without dismantling them. It is possible if you first release the air and drain the water, but it is important to work carefully without mistakes so as not to damage the devices. It will be necessary to shut off the steam line, then organize the water supply through the heating system. Water is spilled until it becomes clean and transparent.

Dry cleaning

This is normal cleaning, which is also necessary to ensure high-quality heating. It is necessary to promptly and thoroughly remove dust from the cracks between sections using a vacuum cleaner or hair dryer. When working with a hairdryer, you must first secure a damp cloth between the wall and the radiator, then direct a stream of air at the wall - the dust will settle on the cloth, which can be washed and used for similar procedures weekly.

Advice! If there are a lot of batteries in the house, cleaning takes time; special brushes with thick sponges are available for sale. The accessory removes dust from several sides of sections at once, speeding up the procedure.

Wet cleaning

Detergent compositions that do not negatively affect the coating are suitable for the process - these are dish soap mixtures, soft washing powders or other products without abrasive particles. The product must be diluted with water to form foam; washing is carried out with a soft sponge or rag. All external parts of the sections, pipes, valves, faucets and other elements of the system are washed. Don’t forget about the wall behind the battery, dust and dirt also settle there.

Washing with special equipment

If the work cannot be done with your own hands, specialists will help. Craftsmen use special equipment for cleaning; work is carried out without dismantling. The peculiarity of using devices at low pressure and high flow rate, therefore any structure can be washed without compromising its integrity. In addition, the use of professional equipment allows you to flush the entire system, and not just one radiator. Work time from 2 hours, price from $10.

Important! To make the slag accumulate much more slowly, professionals install a corrosion inhibitor. Therefore, the process of debris accumulation will be slowed down as much as possible, which means that the next cleaning will not be required soon.

Devices used for household needs:

1. Typhoon. This is a unit in the form of a pneumatic gun that removes toxins that can withstand regular washing. The impact is targeted, the shock wave force is 1.5 km/h.
2. ZEUS-24. Compact unit with high power, effective against plaque and rust. The counter flow of water eliminates all deposits inside sections and pipelines. Used for cleaning radiators with a diameter of 7-150 mm.
3. Mini Mole. An inexpensive and powerful device with 4 nozzles for complete cleaning of pipes and batteries with a diameter of 20-150 mm.

If the problem of blockages in the house occurs frequently, then it is more profitable to purchase a unit for automatic professional cleaning and use it. For the first time, it is better to invite a professional to carry out the process, carefully monitor his actions and then practice cleansing yourself.

The cleanliness of the internal surfaces of heating devices directly determines how efficiently they operate. It happens that during the heating season you notice that the radiators stop heating and they are less warm than the riser pipes. This means it's time to wash them. But how to rinse a heating radiator in an apartment correctly so as not to harm it and effectively clean it of dirt?

Flushing aluminum, bimetallic and cast iron radiators is different. If you don't follow the technology, you can only do harm. In this article we will tell you how to do this.

How to flush a heating radiator

Regardless of the type of radiator and the material from which it is made, the following are suitable for cleaning from internal contamination:

• Chemicals for washing car radiators;
• Caustic soda ( 50-60 gr. for 1 liter of water);
• Alkali ( 20-30 gr. for 1 liter of water);
• Acetic acid ( solution with water 70% or more);
• Drain cleaner.

Some chemicals can be dangerous, so all work must be done with gloves. Also avoid getting washing liquids into your eyes, skin, or respiratory tract.

Sometimes citric acid and whey are used for washing, but they are ineffective for severe contamination.

If you are washing for preventive purposes, you can use a citric acid solution 20-25 gr. for 1 liter of water. Before flushing, the citric acid solution must be boiled and only then poured into the radiator.

If you use acetic acid solution for washing, bring it to up to 100 degrees. This is easy to do - place the container with the solution in a pan of boiling water and wait until it warms up well. The boiling point of acetic acid is +118 °C, so it will not boil with this heating method.

You can rinse a heating radiator with whey, but only if nothing else is at hand. The time it takes for her to clear it is at least 12 hours. If the contamination is severe, the procedure will have to be repeated several times.

How to clean an aluminum heating radiator in an apartment

First of all, you need to disconnect the radiator and remove it. If you carry out work during the heating season, you need to drain the remaining water from it. To do this, unscrew the plug at the top (if installed instead, release it with a special key). After this, place the drain container under the plug at the bottom and carefully unscrew it.

The radiator is connected to the heating main through valves or crimp connections. Unscrew the nut (see photo) on the connection so that it has free movement on both taps or fittings. Pull the radiator away from the pipes - it should come out without applying too much force.

It is best to flush the radiator in the bathroom. Cover it with rags or rags so as not to damage the bathtub coating and the paint on the radiator. As a rule, contamination accumulates at the bottom of the sections. Use rags or rags to remove it. After that, do the same at the top. Rinse the inside with hot water.

You cannot use caustic soda and alkali to flush aluminum radiators. They will corrode the metal, after which dirt will quickly accumulate in it.

Now it's time for the detergent. Screw the plugs into the bottom of the radiator and fill it with the product or solution (as indicated in the instructions for use). Place the battery vertically and let it sit. This is not a quick process, it all depends on the amount of contamination.

After the washing liquid or flushing has done its job, drain it by unscrewing the lower plugs. Close them and fill all sections about halfway with hot water. The aluminum radiator is not too heavy, so give it a shake so the water can wash away any remaining dirt.

Repeat this process until the dirt and buildup are completely gone. It happens that for complete cleaning you will have to flush the radiator two or three times.

Cleaning cast iron radiators is not a problem

Rinse the cast iron heating radiator, as it is heavy, which in itself is inconvenient. In addition, due to the design features, it silts heavily.

To remove a cast iron battery you will have to work hard - as a rule, the connecting couplings and taps are rusted, so it will be difficult to unscrew them. Start by draining off any remaining water. To do this, unscrew the plug at the top, place a basin or other container under the bottom and begin to unscrew it easily.

On cast iron radiators, the plugs can be with either left- or right-hand threads.

If the plugs are painted, use solvent or White Spirit to remove the paint from the junction with the section. After that, try to unscrew it with a gas wrench. If it does not flow, use a rust converter, for example WD-40.

When the remaining water has been drained, it is necessary to disconnect the cast iron radiator from the common line. Usually it is mounted on special couplings (see photo). As with plugs, couplings can also become rusty. Instead of couplings, valves, taps or fittings can be installed. In this case, you will need to unscrew them.

Such couplings usually connect pipes in heating systems with cast iron radiators.

It is best to wash a cast iron battery in a bathtub, which must be completely covered with rags or rags so as not to damage the enamel coating or acrylic.

First, clean the bottom and top using rags. You may need something like a metal rod to remove any stubborn dirt, especially at the bottom.

After this is done, you need to tighten the plugs at the bottom of the cast iron radiator and pour liquid or flushing solution into it. Let it sit for as long as required by the rules of use, then drain it by unscrewing the bottom plug.

Screw the cap back on at the bottom and fill all sections with hot water. Let it sit for 3-5 minutes and drain. Repeat the procedure until the water coming out is as clean as the water coming in.

The level of contamination of cast iron radiators is higher than bimetallic and aluminum ones. Therefore, repeat the cleaning procedure again. You may have to do this 3-4 times.

How to wash bimetallic heating radiators

Bimetallic radiators can be with copper channels or steel. It is not recommended to use aggressive auto chemicals to wash copper channels. An oxide film forms on copper, which protects it from corrosion, so it is better to use special products for flushing heating or sewage systems.

First you need to drain the water from the battery. To do this, unscrew the top plug (if installed, unscrew it completely). After this, place an empty container at the bottom of the radiator and unscrew the bottom plug. When the water stops flowing, we begin dismantling the radiator.

Bimetallic radiators, like aluminum ones, are connected to the heating system through taps, fittings or valves with a crimp nut (see photo). Unscrew the nuts completely from both pipes, then pull the battery away from the line.

Example of an elbow fitting with a floating clamp nut.

It is best to wash the radiator in the bathroom. Cover the inside of the bathtub with rags or rags to avoid damaging it and the paint on the radiator. Then clean the internal horizontal channels with a rag or brush to remove dirt.

If you have a radiator with a copper core, do not use steel wool or a brush to clean it.

If you have a semi-bimetallic radiator (the upper and lower channels are made of steel or copper, and the vertical middle ones are made of aluminum), you cannot use caustic soda and alkali for flushing.

Tighten the plugs and fill the radiator with flushing liquid or solution. Let them sit for as long as indicated in the instructions. After this, drain and rinse the radiator with hot running water. To do this, screw the plugs so that the open holes are located diagonally (see photo).

After the contamination stops coming out and the water at the outlet acquires the same color as at the inlet, repeat the washing procedure again.

How to flush a heating radiator in an apartment without removing it

Many people ask this question, because dismantling a heating battery is often difficult. But if everything is done correctly, this will not be a problem. The only exception is that if you have a top connection to the radiator, then in any case you will have to unscrew one of the fittings or valves to drain water from the system and add flushing fluid.

First of all, you need to drain the remaining water. To do this, unscrew the top cap, place an empty container under the bottom and unscrew it. When the water is completely out, close the bottom plug. If pipes are connected to the lower part, turn off the taps on them like this.

Pour the cleaning solution into the sections through the top hole. Let it sit for as long as necessary. After that, drain it through one of the lower holes. Then fill the radiator with hot water (preferably brought to +90...+95 degrees). Let stand for 3-5 minutes, drain.

Repeat the procedure as many times as necessary. You can determine this by the purity of the water coming out after washing. You will have to spend a lot of flushing solution, but you won’t have to remove the radiator.

Let's not remind everyone that the heating system is the most important network in the house, on which warmth and comfort depend in winter. Efficient heating is the dream of many people. But practice shows that the efficiency indicator decreases over time. And there are several reasons, one of which is contamination of heating radiators with deposits. Unfortunately, the quality of the coolant in domestic heating networks is very low. And what can be done to get rid of these deposits? Option one is to flush the heating device. Therefore, we will answer the question: how to wash radiators?

Let's start our conversation with the fact that operating companies annually, before or after the heating season, purge the entire heating system of a multi-storey building. To do this, using a powerful compressor, air is pumped into the system from the discharge pipe, which is located in the basement of the house. Water is often used instead of air. The compressor pressure is so high that all bottom sediments must be removed, and the radiators will be flushed accordingly. This can be attributed to the question of how to blow out radiators.

No one knows how effective this technology is. After all, control over the washing process is carried out by the operating company. It is clear that the pipes will be washed this way, that’s for sure. But whether the batteries will become clean after this is a big question. Moreover, as often happens, the ill-fated human factor intervenes in the process, which, unfortunately, has not yet led to anything good. Therefore, you should not place high hopes on flushing with a compressor; rely only on yourself.

Washing methods

It is very important to understand the condition of your heating device. That is, how clogged is it with bottom sediments, what are the chances of breaking through the dirt and pulling it out from inside the radiator. The greater the mass of deposits, the more difficult it will be to deal with them, the more active the washing process will have to be carried out.

Flushing with water

This is the simplest option that does not require much effort. That is, the degree of pollution in this case is not the greatest. What do I need to do:

• Close the shut-off valves. If there are none, then you will have to completely drain the coolant from the heating system.
• We dismantle the radiator: unscrew the American ones and remove it.
• If your house or apartment has a cast iron bathtub, then washing can be done in it. If this is a plumbing fixture made of a different material, then the whole process will have to be carried out outside. Old rags are placed in several layers in a cast-iron bath, and the battery will be placed on them.
• All four plugs are removed from the radiator.
• The watering can is removed from the shower hose.
• The radiator is placed on the end.
• A hose is inserted into it and hot water opens. Usually this pressure is enough to remove small deposits. Flush first from one pipe, then from the other.
• To be sure of the final result, turn the radiator over and place it on the other end. And repeat the whole process only on the other side.

Cleaning chemicals

This washing method can also be used if the dirt is very large. True, they cannot be softened or removed with water. Therefore, prepare a piece of metal fittings slightly longer than the length of the radiator itself. Insert the iron rod into the pipe of the device and push it inside until it appears on the other side. Sometimes the dirt is so dense that the rod cannot be pushed through by hand. Only a hammer will help you here, but be very careful. After which you can act with water.

Chemical flushing

Currently, there is a fairly large selection of various chemicals on the market that are used to decompose mud plugs in sewer systems. They can also be used to flush a heating radiator. To do this, you will have to install the bottom plugs in place, it is important that they are installed tightly.

Now place the radiator on its end, with the open pipes facing up, and pour flushing liquid into the battery.

Please note that the liquid must fill the device to the brim. In this state it should stand for a couple of hours. Periodically tap the radiator sections with a mallet (wooden or rubber hammer). After this, you can drain the internal filling and continue washing with water.

Instead of ready-made household chemicals, you can use caustic or soda ash. True, not in dry form, but their solution.

Conclusion

These are the effective methods you can use to flush the radiator. Let's face it, they are not very difficult, so every man can cope with them. Thus, we have answered the question that worries many - how to clean a heating battery.

To create a comfortable microclimate in the apartment, it is necessary to maintain an optimal air temperature for all residents. However, over time, the efficiency of the water heating system decreases, and the rooms warm up much worse. The reason for the decrease in heat transfer is clogging of the batteries, which occurs due to the coolant. Timely cleaning of radiators, which can be done at home, will help remove deposits and restore the functioning of radiators. How to wash heating batteries depends on the nature of the contaminants, operating conditions and the material of the heating elements.

Causes of clogging of the heating system

Hot water, circulating through the heating pipes, interacts with the metal and contributes to the occurrence of chemical processes. As a result, deposits appear on the internal surfaces of the batteries, which interfere with the operation of the system and the heating of the premises in the apartment. In cast iron pipes, blockages are formed due to pockets of corrosion that destroy the metal and settle on the walls in the form of tiny particles. On internal surfaces, deposits occur due to the precipitation of calcium and magnesium salts.

In addition, poor quality coolant contributes to clogging of the heating system. Along with water, sand particles, welding scale, and other types of contaminants move through the pipes, especially if the communications are old. Over time, all elements of the heating system become silted and require cleaning, which you can do yourself.

Signs that batteries need cleaning are:

• increasing the room heating time;
• growth in energy consumption;
• uneven heating of radiators;
• in a heating boiler;
• with hot pipes.

This method is based on removing deposits from the heating system using a jet under enormous pressure. Water is supplied to places where sediment accumulates using special nozzles. As a result, there are no accumulations of silt particles, rust or other contaminants inside.

This method is effective for cast iron elements of the heating network, since due to the porous structure, dense deposits form on the walls, interfering with the operation of the equipment. The rather high cost of hydrodynamic cleaning is compensated by the result.

Chemical

Flushing with chemicals is one of the effective ways to remove deposits. For this purpose, various compositions, solutions of alkali, mineral and organic acids are used. This option is optimal for removing sediment from the inner surface of steel pipes and is used in apartments of multi-story buildings.

Chemical cleaning requires special equipment, which consists of a liquid container, pump and hoses. The composition of the solution is selected taking into account the material of the heating network.

The advantage of this method is the ability not to stop the operation of the heating system, so all technological operations can be carried out in winter. To get the desired result, you only need to correctly select the solution and calculate its concentration.

To clean using this method, you need equipment capable of creating high pressure. Ordinary water is used as the working fluid without the addition of reagents and chemically aggressive substances.

Deposits on the inner surface of the radiator mainly consist of magnesium salts, sodium and other elements. The specificity of such sediments lies in the combination of strength of attachment to the walls and fragility. Therefore, during hydropneumatic treatment, deposits are easily destroyed by turbulent flows.

Deposit removal technology

To rinse and remove sediment from the walls with your own hands, you will need to perform a number of operations. First, turn off the water supply to the heating element. If there are no shut-off valves, then completely drain the water from the utility network. To do this, remove the radiator and take it to the bathroom, and under certain living conditions, to the street.

When cleaning indoors, protect plumbing fixtures from damage using rags or film. The bathtub opening should be covered with a special mesh to prevent large particles from entering the drain during flushing. Then do the following:

• remove the plugs from the batteries, this is done especially carefully for cast iron products;
• using a garden hose, thoroughly rinse the internal surfaces with a stream of water under pressure, tapping on the outside;
