The quality of heat supply systems may deteriorate over time; most people have probably had to deal with this at one time or another. Many people now have to live in houses that were built at least twenty years ago.

It is in such buildings that this problem most often occurs. Poor circulation of the coolant, the role of which is most often played by water, causes poor heating. The corrosion process deteriorates the quality of water, impurities in which are deposited on the inner walls of pipes and radiators, preventing the normal passage of heat.

Naturally, there is a way out of this situation - or, for more “advanced” cases, its chemical cleaning (read also: " "). The photo clearly shows the difference between pipes with a layer of deposits that have accumulated over years of operation of the system without regular cleaning, and pipes cleaned using one of the above methods.

We will look at a detailed description of such a problem, the reasons for its occurrence and a description of solutions in this article. By following the instructions below, you can learn on your own how to clean heating pipes and repair quality work heating system in your house or apartment.

Why is heating system cleaning necessary?

By cleaning your heating system, you will make it work more efficiently and heat your own home it will be much better quality. The problem of contamination of heating equipment lies mainly in inadequate water quality.

Scale, collecting on the inner walls of pipes, radiators and other components of the heating system, causes:

• Acceleration of mechanical wear of pipelines and batteries
• Reduced heating efficiency.

According to experts, scale just one millimeter thick reduces heat transfer by fifteen percent. This significantly reduces the quality of the system and its efficiency. The throughput and heat transfer of the system deteriorate. This result is explained by a decrease thermal resistance, a decrease that is caused by deposits.

Cleaning the heating system - work technology

The complex of works associated with cleaning the heating system consists of the following stages:

• Primary diagnosis. As a result, the nature of the formed scale and the composition of the deposits are determined.
• Selection of what is needed.
• Drawing up a technological map.
• Anti-corrosion treatment is necessary to prevent further education various types of deposits and scale. Doing it follows cleaning.

The following methods of cleaning heating systems from deposits are distinguished:

• Hydrodynamic
• Pneumohydropulse
• Chemical

Chemical cleaning of the heating system

According to experts, the last type of cleaning is so popular and in demand precisely because, in comparison with other methods, it removes almost any deposits most quickly and efficiently.

As a rule, aqueous solutions of organic and mineral acids, solvents, and alkalis are used as cleaning agents. When using this kind of product to clean heating systems, you must be extremely careful and attentive, use eye protection and skin, since each of the solutions listed above is toxic.

For systems equipped with aluminum radiators, these are not suitable, since they can break the tightness of the components.

To carry out the work, special equipment is required:

• Pumps
• Hoses
• Capacities
• Powdered and liquid cleaning products

Carrying out cleaning using this method in preparation for the heating season will require several days (more details: " "). As a result throughput will be fully restored, allowing you to avoid in case of system failure overhaul.

Hydrodynamic cleaning of the heating system

Or – washing batteries. The required result here is achieved using the supplied under high pressure water that destroys deposits and removes them from the system (more details: " "). Special adapters and nozzles are used to connect the pipeline to external equipment that directs water into the system for cleaning.

The disadvantage of this method can be considered the higher cost of work compared to the previous one, which is compensated by the safety of work and high quality cleaning. For heating systems with cast iron radiators, this method is the best, since cast iron radiators are more susceptible to contamination by deposits and are quite difficult to rinse with chemical solutions.

Pneumohydropulse cleaning of the heating system

Is in the best possible way if necessary, clean the system without stopping its operation. A compact water pneumatic gun is capable of cleaning a pipeline with a cross-section of up to fifteen centimeters. Additionally, you will need a connecting hose, “American” connectors and adapters.

There are two most common cleaning methods:

1. Washing boilers with chemical reagents preheated to a certain temperature. The solution is fed into the system using a pump and, reacting with scale and destroying it, then comes out along with the deposits (read also: " ").
2. Mechanical cleaning boilers are made using brushes, scrapers and special mechanical devices. Before cleaning a gas boiler from soot in this way, it is necessary to fill the system with water, which should be brought to a boil, drained, and then brushed over the contaminated surface with a wire brush.

Cleaning the heating system of a private house will allow its owners to extend the period of its effective uninterrupted operation, reduce the cost of heating the mansion and eliminate damage to heating equipment.

During the entire period of operation, contaminants accumulate in the pipes and radiators of the heating system. They negatively affect performance and can lead to serious problems. Therefore, the owner faces the question: how and with what to flush the heating system of the house: radiators, radiators, pipes? After all, the quality of the entire heating supply to the house will depend on this.

Causes of clogged heating pipes

The water contains many additional components. The most predominant are iron, calcium and magnesium. When exposed to relatively high temperatures they are released in the form of small fractions that settle on the inner surface of pipes and radiators.

Therefore, before washing aluminum radiators, you need to find out the nature of the contamination. In addition to calcium and magnesium deposits, oxide deposits can form due to natural rusting of metal heating components. Depending on the nature of the contamination, the optimal cleaning technology is selected.

Usually the plaque includes the following elements:

• Iron oxides. In a system with steel pipelines and radiators, they can occupy up to 25% of the total plaque volume;
• Calcium and magnesium deposits occupy up to 60%;
• Oxides of copper, sulfur and zinc – up to 15%.

Since the heating radiator in an apartment should be flushed only after a preliminary analysis of the nature of the contamination, it is recommended to first take a plaque sample. To do this, you can dismantle part of the pipeline. In practice, this is not always done, especially for heating systems installed relatively recently.

The frequency of flushing the heating system depends on the composition of the coolant, temperature regime work, as well as from the materials used to manufacture pipes and radiators.

Heating system diagnostics

How to flush an aluminum radiator and when should it be done? First of all, you need to decide on the feasibility of carrying out the system cleaning procedure. It depends on several factors that can be identified independently.

The main sign of the urgency of resolving the issue of how to flush the heating system in apartment building is uneven heat transfer from radiators. Those. In some areas the heating temperature is normal, while in others it is not. Relevance of flushing heating batteries can be determined by touch (which is not entirely correct) or using a thermal imager and precision thermometers.

Since it is possible to flush the heating system in a private house only after comparing its current indicators with the required ones, you should check the pressure at various areas scheme. In places where pipes and radiators are clogged, the wire diameter decreases, which entails pressure surges. This is also one of the factors for mandatory cleaning.

What else external signs may indicate a blockage?

• Increased noise level. It is a consequence of changes in the volume of passage hot water in various parts of the system;
• Frequent activation of the safety group - air vent and bleed valve.

Having found out that it is necessary to flush the heating system in a private house, you should choose the right technology. It depends on the material used to make pipes and radiators.

Regardless of the symptoms described above, cleaning the heating system must be performed at least once every 5-6 seasons of operation.

Methods for flushing the heating system

Before flushing the heating system, you should choose the best method for cleaning pipes and radiators from blockages. One of the problems is the density of scale, which most often has a uniform structure located on the inner surface of heating devices.

Therefore, before flushing a cast-iron heating radiator, this deposit should be destroyed, breaking it into individual small-sized components. Then, using a flow of liquid, they are removed from the heating. This process becomes more complicated if the heating network components are made of various materials– metal, polymers. Traditional chemical cleaning can damage some of them. Therefore, it is advisable to choose a method of mechanical action on scale.

Hydrodynamic heating flushing

This is one of the most labor-intensive methods for removing contamination. Its essence lies in the impact of a shock wave of water on sediments. This requires special pumping equipment, nozzles and fluid supply hose.

The hydrodynamic method can only be used for pipelines or radiators with a simple layout of water channels. How to flush long heating pipes? The use of chemical compounds will not be economically beneficial due to the significant volume of the system. Therefore, in such cases, scale is removed mechanically.

This procedure is carried out according to the following scheme:

1. The coolant is removed from the lines.
2. Areas for flushing the heating system in an apartment building or cottage are identified.
3. The pipe section is dismantled and the hose with the nozzle is inserted into the main line.
4. Water is supplied under pressure, which destroys the scale.

After this, the system is filled with water and washed several times to remove any remaining scale. Before this you need to dismantle everything internal filters. So that contaminant particles do not remain in the system.

But how to rinse heating radiators if their internal configuration has complex shape? The above method in in this case not effective. Therefore, you need to choose another, alternative.

For heating with a short length of pipelines, the hydrodynamic method may be advisable only if there are large solid deposits on the surface of pipes and radiators.

Chemical flushing of heating

Flushing heating radiators in an apartment is best done using chemical reagents. They act on scale, destroying it and crushing it into individual small components.

To flush the heating system in a private home, you need to choose the right composition. Some of them can destroy aluminum or polymer pipes. Therefore, before purchasing, you should read the instructions from the manufacturer.

For self-cleaning heating you will need a pump and a container for liquid. These devices are connected to the main line using pipes. This can be done as follows: separate area, and on the entire system as a whole. For many chemicals, it is necessary to first dilute the composition with water. After finishing preparatory stage The procedure for flushing the heating system in a private house is carried out according to the following scheme:

1. Draining coolant from the network.
2. Filling the treatment station tank with the prepared chemical composition.
3. Turn on the pump and fill the pipelines and batteries with cleaning liquid.
4. It usually takes 2-3 hours of exposure to the composition to destroy and dissolve the scale.
5. Reusable fluid circulation in the system. This is carried out until no deposits are observed in the container filter.

After flushing the aluminum heating radiator and pipes, the system is cleaned with water to remove chemicals. Then the heating must be pressed and its tightness checked.

The cost of cleaning products for aluminum heating radiators depends on the composition and manufacturer. For a small system, it is recommended to purchase already ready liquid, and for autonomous ones - a concentrate that must be diluted with water.

If there was antifreeze in the system, before chemical cleaning you need to first flush the pipes with water 2-3 times.

Pulse pneumatic heating flushing

With its help, you can wash aluminum radiators without fear of destroying their surface. It's relative new method, which requires special equipment and experience in its operation.

The principle of cleaning radiators is a short-term pulse effect on the hydraulic medium - water. This creates a pressure of up to 12 atm, with a shock wave speed of about 1400 m/sec. This will be enough to flush the heating system, regardless of its configuration. This technique allows you to remove plaque in long highways without dismantling individual components.

However, before flushing the heating radiator, you need to familiarize yourself with the features of pulse hydraulic cleaning:

• The maximum pipe diameter is 4 inches;
• Clogging is effectively removed even at a distance of 60 meters from the installation of the impact ram;
• Virtually no effect on integrity assembly units heating - fittings, threaded and welded connections.

To flush a cast-iron heating radiator in an apartment building, you must first shut off the flow of coolant in this section of the pipeline. This can be done without permission management company, if there is a bypass in the battery harness. Then a hydraulic ram is installed in one of the pipes and several cleaning cycles are performed.

Timely flushing of the heating radiator will increase its heat transfer by 20-25%. Those. will actually restore this indicator to the normalized factory value.

Do-it-yourself heating cleaning

Is it possible to flush heating pipes with your own hands? To do this, you will need to conduct a preliminary analysis of the degree of contamination of the highway. Most of the scale is formed in the zone of maximum thermal effects– in pipelines located closest to the boiler. This is where aluminum radiators most often need cleaning.

If the system has not been cleaned for 15-20 years, it is recommended to dismantle the radiators, as well as the boiler heat exchanger. In this way, you can most effectively flush the heating system in a private home. To do this, you do not need to remove the pipes - just temporarily dismantle the batteries.

Then you should select equipment for washing the heating system. Since this procedure is rarely performed (once every 5-6 years), it is best to take pumping station for rent. During the cleaning process, you will need to drain the contaminated water. For temporary storage, use an airtight container. This is relevant when performing flushing cast iron batteries heating systems, in which scale accumulates the most during operation.

Then the tank is filled with the already diluted cleaning liquid concentrate. The pump pipes are connected to the battery, and several circulations of the purifier are performed. They continue until there are no scale components in the filter. A similar scheme for flushing heating in a private house is carried out in the summer - during this period there is no coolant in the system.

Heating systems perform a restorative function, helping to restore the original performance and heat transfer characteristics of the pipeline, boiler and radiators.

The background of the problem

The reason for the decrease in the efficiency of heating equipment is banal and simple: the water circulating in pipes and radiators contains foreign impurities. Therefore, after a long period of operation, various dense deposits settle on the walls of hollow products and elements of boiler equipment, reducing the thermal conductivity of the system several times. As a result, the temperature in living quarters drops.

To winter period the heating worked as expected and the heated house was warm and cozy; before the heating season begins, care should be taken to clean the systems. These measures will also help save money allocated for heating.

Most effective method Elimination of scale in pipes involves treatment with special reagents.

How to choose a liquid for flushing the heating system

When choosing a flushing product, professionals urge you to be guided by a number of criteria.

1. Fluid for flushing the heating system may contain either acidic or alkaline components. The first ones are activated as quickly as possible, but interaction with them requires extreme caution - there is a danger of damaging the washed objects and causing damage to health. The latter are safer, but not as efficient in operation. To achieve a positive result you will have to spend a lot of time.

1. It is preferable to choose a product with an anti-corrosion effect. If the flushing liquid does not provide this function, you will have to additionally treat the system with a special substance containing inhibitors and passivators that prevent the corrosion process from starting.
2. Before using, or better yet before purchasing, the chosen product, you should make sure that it is suitable for the material from which the pipes and other elements of the heating system are made. If you neglect this, you can damage the equipment and spend a lot of money on replacing it.

In what form are the reagents presented when sold?

Flushing the heating using chemical reagents will help keep the system in order. Experts say that this kind of prevention should be organized annually. Chemical reagents for flushing heating equipment are available in three types:

1. concentrate - before use, diluted with water in proportions according to the manufacturer’s instructions;
2. powder - in the same way must be diluted with water;
3. ready composition.

Rules for disposal of rinsing products

By adding special components to the preparations, the waste after flushing is allowed to be discharged into the general sewer system. This liquid is capable of biodegradability. If the reagent does not contain biodegradable additives, then a neutralizer must be added to it.

Popular products for flushing heating systems

To prevent clogging of pipes and batteries, experts in this field recommend using safe flushing chemicals. Today, solutions and concentrates are sold on the domestic market that are capable of flushing heating systems of any configuration.

By flushing your heating system you can restore its youth. Often, clogged radiators cause the apartment to become cool. Below we will look at how you can solve the issue as cheaply as possible...

It is also important - how to determine that it is no longer possible to do without washing? Has the time come that the heating system needs to be cleaned...
Next - the main ways to clean the heating system in houses and apartments - how to do it correctly, what to do...

How pipes and radiators become overgrown and dirty

There are salts and metals in the water, dissolved oxygen, which react with steel and cause its corrosion; gradual overgrowth with corrosive deposits occurs steel pipes. The internal clearance decreases until the cross section is completely blocked.

Also in the water there are suspended particles of the most different materials, minerals and substances that settle in places where the flow is slow, forming silt deposits. As a rule, this occurs on horizontal surfaces of radiators.

As a result, little coolant is supplied, and the rate of heat transfer through deposits decreases, so in general, heat transfer from the heating system drops many times over.

How to determine the need for flushing

Overgrowing of steel pipes and the presence of sludge in radiators reduces the performance of heating systems significantly. It can be cold in houses and apartments.

But do not confuse clogging of the heating with airing of the radiator (the top is cold) or an entire branch, or simply with unsatisfactory operation central heating.

An obvious signal that radiators are clogged is that the lower part of the radiator is cooling significantly, and the dead-end part may be cold. It is obvious that the coolant circulates only through the sections closest to the connection points.

At the same time, the supply pipes are hot, which indicates normal operation central heating system - it contains hot coolant under pressure.

Why is heating flushing rare in private homes?

In private houses in Lately metal-plastic, polypropylene, copper, galvanized pipes were installed. Overgrowth and corrosion do not occur in them. And after 50 years of operation, these pipes are like new.

In private homes, as a rule, the exchange of water in the heating system is not significant. Therefore, the addition of salts and sediments is minimal and could not cause anything serious. And some owners also used distilled, rainwater, boiled water for filling.

Only with rare exceptions is it possible for the home heating network to become silted due to high water exchange or the use of too contaminated water. A large exchange is possible due to an incorrectly made system, in the presence of leaks, due to constantly existing connection to the water supply due to evaporation of water in open containers.

But flushing the entire system of a private home with water is required after using anti-freeze products in order to remove toxic and aggressive residues and products of their destructive action.

What happens to gravity home heating?

In a gravity system, which was widely created from steel pipes and cast iron radiators in private homes in the last century, and which is still widely used, one way or another will be the most significant changes, compared to systems created from plastic pipes and aluminum (steel) radiators coated inside with polymer.

Steel pipes were used with large diameters, so corrosion activity, during normal water exchange, did not significantly affect performance. But the low speed of water movement created conditions for the deposition of silt, not only in radiators, but also in pipes. As a result, under certain circumstances (high pollution and high exchange) a home system of steel pipes can significantly reduce the ability to transfer heat, especially by gravity.

Signs of contamination will be boiling of the boiler, with relatively cold radiators, which was not observed when the system was young. Then cleaning is needed.

How do radiators in an apartment get dirty?

In centralized heating of multi-storey buildings, the speed of the coolant through the pipes is much greater. In this way, a minimum temperature difference is created along the length of the lines, with large quantities connected heating devices.

And in radiators the speed is much lower. In fact, radiators are settling tanks for central heating coolant. At the same time, the exchange of water in the system is very large, it is not limited, since a lot of coolant is lost, users take it apart, every year it is replaced with a new one...

Radiators in apartments become significantly clogged with silt deposits. Sediment accumulates where water speed is slower. With a return-flow circuit, the radiator dead end is usually always clogged.
Steel riser pipes also quickly deteriorate.

Rare cleaning methods - chemical reagent

The use of chemical reagents to clean the heating network is only possible if its use is guaranteed in a designated section of the network, after which it must be completely washed out of the system with water and disposed of in in the prescribed manner. Alkaline and acidic solvents are used to remove rust formations and fallen mineral deposits. The compositions can be purchased at the store. Next, you need to act in accordance with the attached instructions.

In a private home, such washing is not problematic, but you need special equipment with a pump to fill the reagent. As well as mandatory removal and disposal of acids. Part of the central heating network can also be flushed in this way by specialists if similar works planned.
But it is worth remembering that as a result of a chemical attack, defects in the pipes may be revealed, and the service life of these products will be reduced.

Any pouring of aggressive substances inside reduces the service life of the system as a whole, at a minimum. If done incorrectly, it will disable expensive equipment without the possibility of repair.

What happens during chemical washing

• There are small-diameter steel pipes that are overgrown with deposits from the inside, so the system does not work.
• Such a system includes special equipment with a container with a chemical reactant and a circulation pump. Usually they remove the regular one circulation pump and instead, chemical cleaning equipment is connected to the heating system.
• A chemical reagent is supplied to the system and circulates through it for some time.
• The spent reagent along with the garbage is poured into containers, removed and disposed of.
• The system is filled with water several times and washed.

Hydropneumatic cleaning of radiator interiors

Destruction of silt deposits in radiators by pneumatic or hydraulic shock is a long-used method of flushing heating systems. But it can only be carried out with special equipment that creates a water hammer impulse. Therefore, this is done by specialists servicing large heating networks. The lower radiator plug is removed and loosened with a jet. Then the coolant is supplied to a number of treated radiators, and the outgoing fluid is drained into the sewer.

Or the radiator is completely dismantled, taken outside, and purged using machines.
In any case, mechanical destruction in radiators is much safer, technically more reliable, and more environmentally friendly than the use of chemicals. reagents.

What happens during pulse cleaning

• The radiator is opened (the plug is unscrewed). The hose of the pneumatic equipment is connected.
• The system is filled with water, and the equipment pulses to destroy deposits inside the radiator.
• The water is drained down the drain along with the garbage.

Folk method for cleaning a heating system

When it becomes cool in the apartments, due to the fact that the heating radiators are half cold due to the accumulation of deposits, then it is time to do the flushing. If it is not possible to use hydraulic destruction and supply water through a riser with discharge to the sewer, then proceed as usual. The radiator is dismantled and redirected to the sewer or to the street. The plugs from the battery are unscrewed. By mechanical means, with long brushes, dense deposits are destroyed, and the internal surfaces are washed with the pressure of water from the sludge.

The flushing operation is usually combined with the complete replacement of steel risers with plastic options -

Partly because when dismantling radiators, the pipes are often destroyed, since unscrewing the overgrown threaded connections difficult, and the walls of steel pipelines have become thin.

Another option for flushing is to stuff some chemical into the removed radiator. But such actions do not guarantee results; it is better not to repeat them.

A simplified method for flushing radiators in apartments

IN centralized networks Heating radiators are connected to the risers so that they have areas where the flow of water slows down. This is where the deposits will be in the lower part. When connected according to the “bottom-to-bottom” scheme, there will be no contamination, since the jet speed is constant and the deposit area is constantly washed. But this connection is not recommended and is not used due to the general decrease in the efficiency of the heating device.

But it is possible to create a temporary flushing jet through the bottom of the radiator. The only question is how to organize this correctly without dismantling the device.

In the summer, as a rule, radiators are dry, and it becomes possible to open the bottom plug, and also unscrew it, possibly with heating blowtorch, radiator plug. Then you can simply clean it with a long steel brush and rinse with a stream of water from a hose without removing the device. And this is usually enough to significantly increase heat transfer for some time.

Additionally, what cannot be done according to centralized heating standards:

• Instead of a plug, securely screw a ball valve with a fitting into the plug. After supplying coolant to the system, you can use a hose from the tap to the toilet to flush the radiator with coolant. Also, periodic flushing will prevent silting. But such a tap is a violation.

Is it worth doing preventative flushing?

There is no need to worry about the threat of clogging of the heating system. Opening the system, and even more so pouring some kind of chemical substances, without a very serious reason, should not be.

It is necessary to plan flushing of the heating system only after an unacceptable decrease in the amount of heat generated.
It is recommended to use mechanical (hydro-mechanical) methods for cleaning radiators.

There is no point in restoring the internal cross-section of steel pipes using a chemical method - it is better to replace them immediately.

Reading time ≈ 9 minutes

The heating system is an important component of every home.

This design includes not only pipelines, but also batteries. The heat supply of the entire room will depend on the condition they are in. But in order to wash it, you should learn about all the features of such a procedure and determine how such washing should be done.

Main causes of pipe contamination

By heating pipes water is coming. And as you know, water contains many components that can affect metal. IN water composition most of all calcium, iron, magnesium. When water heats up, they are released in small quantities, deposited inside pipes and other parts of the system from the inside.
Oxide deposits also often form, which is the result of rusting processes of metal elements. Therefore, it is important to determine what kind of pollution has occurred and, based on this, use certain technologies for cleaning.

Dirt can accumulate for years

Most often, the plaque has the following composition:

• iron oxides - up to 25% of the total plaque (if we talk about a steel pipeline);
• magnesium and calcium deposits – 50-60%;
• oxides of sulfur, zinc and copper – no more than 15%.

As you can see, the plaque can be completely different composition. Therefore, it is recommended to take a sample before washing and then determine how to produce it. This will not only save your energy, but also give maximum results.

In order to take plaque for testing, the pipeline should be partially disassembled. But according to statistics, this stage is often skipped. Especially if the heating system was installed not so long ago.

Important: How often the system should be flushed directly depends on the composition of the coolant used, the operating temperature, the material of the pipe itself and the battery.

Features of diagnosing the heating system at home

Many people are concerned about the question: when is it worth washing? Initially, the feasibility of such an action should be determined. Several factors indicate this. They are easy to identify at home yourself.

The first indicator of the need for a system is recognized as uneven heating and, consequently, heat transfer from the batteries. In other words, the battery will be hot in some places and cold or warm in others. This is very easy to determine - touch the radiator. But it is more correct to use a thermal imager or a point thermometer.

Variations in radiator heat transfer

In a private home, it is necessary to compare the current indicators with those stated in the characteristics. To do this, you need to measure the pressure in different zones scheme. Where the pipe is clogged, the wire diameter will be smaller. As a result, pressure drops appear. This phenomenon requires flushing the heating system.

Possible external indicators that indicate a blockage in the pipes

If you hear a lot of noise, this indicates that there is a blockage inside the pipes. Noises arise due to the fact that the volume of hot water passing through the different zones heating system.

Also, the need for flushing is indicated by the fairly frequent activation of safety groups. These include an air vent and a bleed valve.

When you are sure that you can’t do without flushing, then it’s time to choose optimal technology and learn how to flush the heating system in a private home with your own hands to ensure the greatest efficiency.

Pollution can be enormous

Methods for self-flushing the heating system

To heating season did not bring any unpleasant surprises, choose the most suitable method for cleaning pipes from contamination. The problem remains the density of the scale. It most often has the same structure, which is located inside the heating devices.

Therefore, if the house has a cast iron radiator that needs to be washed, then the first thing you need to do is divide this deposit into separate components, which will be small. And after that, use liquid pressure to remove the blockage from the pipe.

The presence of combined system heating system, which consists of materials different types– metal, polymers and so on. If you choose standard chemical cleaning, the aggressiveness may damage the pipes. So in this case it is worth using mechanical action on the scale.

You can clean the scale yourself

Hydrodynamic method for cleaning a heating system

This method is the most labor-intensive in terms of removing contamination. The essence of the method is the use of a shock wave of water, which is directed and acts on the accumulated blockage.

Such flushing of the system involves the use of specialized equipment, including:

• pumping system;
• professional nozzle;
• a special hose through which liquid is supplied.

Equipment for hydrodynamic cleaning of pipes

The hydrodynamic cleaning method is only suitable for batteries or pipelines that have simple diagram placement of water channels. When there are pipes of considerable length, then the use chemical methods becomes unprofitable in economic terms due to the significant volumes of the system.

Washing is carried out step by step

Chemical method for cleaning the heating system of a private home

For apartment building It is best to use chemicals to clean the heating system. They are capable of breaking down scale into small elements. But to use chemical method in a private home, you should carefully select the chemical composition of the reagents. After all, some can negatively affect pipes made of aluminum and polymers. So before purchasing, consult with a specialist or carefully read the instructions provided by the manufacturer.

Chemical reagents for flushing pipes

Here too some equipment should be used to achieve efficiency. You need to stock up on a pump and a container that will contain the liquid. The equipment must be connected to the main line using pipes. The connection can be in a specific area or throughout the entire heating system in general.

Most often, the purchased chemical reagent must be diluted with water (the proportions are indicated in the instructions). When all preparations are completed, you should proceed to direct washing according to this scheme.

The price of chemical solutions that are intended for flushing a heating system with aluminum radiators and pipes directly depends on chemical composition and manufacturer. If the heating system is small, then it is better to buy a liquid that is ready for use. In case there is autonomous system, then it is better to take a concentrate that needs to be diluted with water.
Important: When using antifreeze in the system, be sure to chemicals Flush the system at least 2-3 times with plain water.

Small secrets of rinsing

Since cleaning the system, according to the recommendations of specialists, should occur once every 5-6 years, you do not need to buy special equipment. It is enough to rent it for the time of use. This will save you a lot of money and won't take up space in your pantry.

If you need to flush a system that has been uncleaned for about 20 years, then experts recommend dismantling all radiators and the boiler heat exchanger. Thanks to this, cleaning the heating system in a private home will be as effective as possible. There is no need to dismantle the pipes.

Removing the radiator for cleaning

Take care of containers that will be used to drain and store liquid from the network. Especially if you have cast iron pipelines. This is where most of the various types of pollution are generated.

The heating system is playing important role in every home, especially in private homes. Your comfort and health during the cold season depends on its functioning. But with any operation, contamination cannot be avoided. So knowing how to flush the heating system in a private home, doing it yourself, is not only interesting, but also useful. To learn about all the secrets and nuances of flushing your heating system yourself, watch the video with practical tips.
