Homemade washing machine. Apparatus for flushing heating

It is not uncommon for the owner of this heater to flush the heat exchanger of a gas boiler. For example, when there are no such masters in the settlement, and there is no desire or opportunity to bring the boiler to the city. Although, it is worth recognizing that cleaning this part is a rather expensive service, which not everyone can pay for. In addition, only trusted companies with specialized equipment should trust this work. If you have to turn to "handicraft" craftsmen, then it's better to make a booster for flushing heat exchangers with your own hands and perform the procedure yourself.

Why cleaning is necessary

Sometimes there are certain problems in the operation of the heating system and to get rid of them, it is enough just to clean the equipment.

This is due to the fact that during the long-term operation of the boiler, various substances and deposits accumulate in the heat exchanger, which can lead to the complete destruction of this part of the equipment.

In addition, under the influence high temperatures impurities deposited on the heat exchanger react with each other, which in turn will lead to a decrease in the performance properties of the entire heating system as a whole.

So, they can interfere with high-quality heat transfer:

  • hardness salts;
  • dissolved iron.

Hardness salts and excess iron are characteristic of water in many regions of our country, so the problem is relevant for many!

In order for your boiler to operate at the maximum level of efficiency, and the heat exchanger to keep its performance for as long as possible, it is recommended to periodically clean the equipment using special liquids and solutions for this, which we will discuss in more detail below.

The frequency of cleaning directly depends on what kind of liquid you use in the heating system:

  • if it is ordinary, clean water, then this procedure must be performed every four years;
  • if it is antifreeze, then the cleaning procedure is performed every two years.

When using antifreeze, it is extremely important to replace it on time. If this is not done, then the entire heating system of the house can be seriously damaged.

Of course, ideally, this should be done by specialists, but the cost of their servants is unreasonably high. Therefore, if desired, with a little skill, you can achieve an acceptable result with your own hands.

Booster preparation and pumping features

It should be noted right away that the biggest problem in this situation is the booster, that is, a special device that ensures the pumping of liquid through the heat exchanger and at the same time removes fumes.

It is unlikely that you will be able to take it from someone you know. And it doesn’t make sense to buy it yourself - its cost exceeds $ 300 (and these are not the highest quality and reliable devices). It is clear that the acquisition is unjustified. Therefore, the only true option is to make a booster from improvised materials with your own hands.

An example of how to clean the heat exchanger of a gas boiler in the video:

For these purposes, an old but working pump may be suitable. washing machine. If you don’t have one, then you can easily buy it at a “flea market” or on the Internet for a small amount.

Connection Features

It would seem that there is nothing difficult in next steps no, but in fact it is not so simple, because it is important to correctly connect the flushing tubes coming from the pump.

To do this, you need to make a special mounting plate. Carefully study the features of your equipment and based on this:

  • take two solid metal plates, the thickness of which is 2.5 millimeters;
  • according to the device, drill holes to match the holes in the heat exchanger;
  • in a regular plumbing store, buy four so-called "Americans" with a diameter of half an inch and several gaskets for them;
  • use only the inside of the "American", installing them in the bottom hole of each plate;
  • using bolts, fix the plates so that the fittings are pressed as tightly as possible to the heat exchanger.

To ensure the connection of hoses, even ordinary brass fittings with a diameter of ¾ inch will do. They can be used for both main and secondary heat exchangers. By the way, how to properly connect a booster for flushing heat exchangers with your own hands, see the video presented in this article.

The preparation does not end there. Now you need additional capacity. It may be ordinary plastic canister or even a five or six liter water bottle. Be sure to wash the container well to remove even the slightest contamination.

Install a fitting at the bottom that will allow you to connect the hose. The fitting must be fixed tightly and firmly. You may need to melt the hole under it a little, install a fitting, and when the plastic starts to harden, it will wrap around it tightly and ensure tightness.

If there is a desire and opportunity, install a tap at the outlet, but this is not necessary.

Washing agent

The next step is to choose a flushing agent. There are a great many such solutions, and on specialized forums, each specialist advises the remedy that he himself used. To be honest, you should not unconditionally believe such statements, there is a very high probability that the liquid is actually imperfect.

For example, some stubbornly advise using a 10% hydrochloric acid solution. Or phosphoric acid. However, we strongly recommend not to use acidic solutions - they can burn through the heat exchanger and you will have to buy a new one! Or go in search of a master capable of high-quality and reliable soldering a hole burned with acid.

It is recommended to use special solutions for cleaning - their price is quite high, but the result is appropriate. In addition, they are completely safe. So, for example, positive results were noted and a really large number of "live" good reviews for Detex, one bottle is enough to create ten liters of solution.

Step-by-step guide to self-cleaning

Now that you have everything ready, you can start flushing. The sequence of actions will be as follows:

  • take the pump from the washing machine;
  • connect it to the devices you have created - a container for flushing liquid and the heat exchanger itself;
  • pour six liters of clean water preheated to a temperature of 50 degrees into a container;
  • turn on the pump;
  • drive water through the created circular system - this is necessary in order to make sure that the entire system is reliable, durable and does not let liquid through anywhere;
  • after you are convinced of the reliability of the system, turn off the pump;
  • pour cleaning liquid into the container - Detex or any other (we remind you, do not listen to artisans and "professionals" on forums on the Internet - do not use acid solutions, they can burn through the heat exchanger!);
  • start the pump and let it run for about forty minutes.

If you use a transparent hose at the outlet that conveys the liquid back to the container, you will be able to see the dirt being washed out.

After flushing the secondary heat exchanger for forty minutes, move your fixture to the main one and also flush it for about forty minutes. The result is amazing - heat transfer devices will be as clean as they were at the time of purchase.

Cleaning times are approximate. If the heat exchanger is very dirty, flushing should be done longer. If it is relatively clean, the pump run time can be reduced. Here, see for yourself in the process - by the level of contamination of the liquid. That is why it is recommended to install transparent tubes that allow you to visually control the cleaning process.

After cleaning with a special solution, connect the heat exchangers to a water tap. drive away clean water about five to seven minutes. This is necessary to wash out the remnants of the product.

In this case, professional craftsmen use a special neutralizer - if you have the financial ability, you can buy it, and if you don’t want to spend money, then use this method of removing cleaner residues, it is quite justified in terms of the final result.

To better understand how to make a booster for flushing heat exchangers with your own hands, watch the video:

As you can see, it is not at all difficult to create an efficient and workable booster for flushing heat exchangers with your own hands, the photo of which is presented in the article.

Be sure to first study the issue of dismantling the heat exchanger so as not to damage it. In general, there is nothing complicated about this, but there are certain features of dismantling - it all depends on the manufacturer and model of the boiler.

Well, after you remove the heat exchanger, clean the boiler itself - why not take advantage of this opportunity? To do this, take a regular soft brush and arm yourself with a vacuum cleaner. When cleaning, pay special attention to the burner, but do not show excessive zeal so as not to accidentally break or damage anything.

At TeploProfi you can purchase washing stations for heat exchangers, boilers, boilers, electric, gas water heaters and similar devices. We offer a wide range of models that differ in technical parameters and performance.

How to choose a pump for flushing a heat exchanger?

Installations for flushing heat exchangers are different:

  • By pressure
  • performance
  • tank size
  • The presence of a reverse

To select an installation, you need to understand the volume of heat exchangers you need to flush.

In practice, it is best to choose a unit with a tank volume 2-4 times less than the volume of a heat exchanger with automatic reversal. In this case, flushing will be the most comfortable and convenient, the performance and pressure of the pump will also be more optimal.

The volume of the heat exchanger can be found in the passport. If you can't find your passport, don't worry pump with a tank volume of 20-40 liters will be enough to flush heat exchangers for heating and hot water supply of most residential apartment buildings.

How to choose a fluid for flushing a heat exchanger?

Heat exchangers for heating / ventilation and hot water supply are made of steel plates ( Aisi 304 and Aisi 316) and seals ( EPDM), Steeltex Inox liquid is suitable for washing them, you will also need a neutralizer to eliminate chemistry.

Pumping units for flushing heating systems

Heating flushing equipment creates increased pressure in the pipeline. The system is cleaned by forced circulation of the injected reagents. Chemical preparations, moving through the pipes of a closed highway, remove a large amount of salts, deposits and contaminants.

You can determine that the heating system is dirty and needs to be flushed by the following signs:

  • Reduced heat transfer;
  • Weak heating of individual radiators or heating circuit;
  • Clogged mud filter;
  • Frequent shutdown of the boiler;
  • Increase in fuel consumption.

A powerful flushing pump is an indispensable unit used in complex branched heating circuits. The equipment is used in residential apartment buildings, as well as in private households, in commercial and industrial buildings. With regular use pumping unit and special reagents, the risk of blockages in the pipeline is reduced to zero.

Features of flushing heat exchangers

Untimely maintenance of heat exchange devices leads to the formation of scale on the walls and premature failure of the units. To prevent breakdown, it is necessary to regularly use the equipment for flushing heat exchangers in combination with acid reagents.

Once inside the unit, the acid-containing solution softens hard deposits and exfoliates scale and rust under the influence of forced circulation created by the pump. The booster for heat exchangers allows cleaning the circuits without dismantling the structure. The advantage of this technique is the integrity of welded or rolled joints. For more effective work the units are equipped with the function of changing the direction of the washing liquid flow.

The heat exchanger washing plant is a professional equipment widely used by service companies serving boiler houses in residential, public and industrial buildings. In TeploProfi you can order a high-performance pump for flushing heat exchangers.

We also offer to purchase concentrated reagents that quickly and effectively remove lime, corrosion and other contaminants. Remember - timely preventive maintenance, washing and cleaning of heat exchange devices increases their service life!

Any technique needs maintenance, and gas boilers not an exception. Many homeowners for years and even decades do not remember the need to flush the heat exchanger, but sooner or later this has to be done. Regular maintenance not only prolongs the life of the equipment, but also saves the owner money. By what signs do they determine that flushing of boilers is needed? How to do it with your own hands?

Why do you need regular cleaning of the gas boiler

Most of the year, water is constantly circulating in the heating system. Over time, a coating of salts, lime, impurities that enter the coolant settles on the details of the equipment. The harder the water, the more mineral deposits appear on the elements of the system. They remain in the heat exchanger for the gas boiler, which negatively affects its operation.

Heating equipment in the house

The principle of operation of heating equipment is based on the fact that the coolant is heated, passing through the curved channels of the coil. To raise the temperature of the liquid, special plates are used. Thanks to these additional elements, the coil itself and the water entering it warm up more evenly. When assembled, the system looks like a car radiator.

The efficiency of the equipment largely depends on the thermal conductivity of the materials from which it is assembled. Usually copper or alloys with this metal are used. Any growths, deposits on the inner surfaces of the coil tubes lead to a decrease in thermal conductivity and a deterioration in the operation of the system.

Deposits in the heat exchanger for the boiler

Preventive measures are beneficial

If the equipment is not cleaned in a timely manner, problems may arise:

  1. The heat exchanger of a gas boiler constantly overheats and fails faster. It can be replaced, but such repairs are very expensive. To this amount should also be added the inconvenience and cost of heating the house during the period when the equipment is being repaired. Electric heaters are usually included, and this significantly increases the cost of repairs.
  2. Limescale greatly complicates the passage of the coolant through the system. The more scale, the higher the load on the circulation pump. The equipment has to constantly work in emergency mode, which leads to natural wear of spare parts and negatively affects its service life.
  3. A clogged boiler heat exchanger works less efficiently. It takes more energy to heat it up. Accordingly, the gas consumption increases (on average by 10-15%). This means that the owner will overpay for heating, and the house will warm up worse. Simple calculations show that during the season an amount close to that paid on bills for the whole month will come out.

Do-it-yourself device for washing heat exchangers

How often do you clean the heat exchanger in a gas boiler

The frequency of cleaning the heat exchanger depends primarily on the type of coolant and the design features of the unit itself. Least of all, it is necessary to service single-circuit boilers in heating systems in which purified water is used as a heat carrier. To keep them in good condition, it is enough to carry out preventive maintenance every 4 years.

If untreated water circulates in the system, then the boiler should be flushed once every 2-3 years. If the water is hard, then the cleaning regimen is once every 2 years. The secondary heat exchanger of a double-circuit boiler must be flushed with the same frequency, because. through it comes unfiltered tap water with impurities.

Most often, maintenance is required for equipment in heating systems, where antifreeze is used as a coolant. It should be washed at least once every 2 years. In addition, you have to control the expiration date of antifreeze, replace it in a timely manner. Otherwise, the efficiency of the system will decrease, and heating costs will increase.

When cleaning heat exchangers, pay attention to appearance boilers, nozzles and, if necessary, carry out repair work. You should also monitor the condition of the chimneys, clean them from soot in time. These simple measures prolong the life of the heating equipment, prevent breakdowns.

Antifreeze for heating systems

Contact the experts or do it yourself

Professional cleaning of heating boilers - expensive pleasure. Depending on the condition of the equipment and the features of its operation, the amounts can range from several tens to hundreds of dollars. In addition, the masters rarely arrive in the next few hours, sometimes they have to wait several days. It is not comfortable.

The cost of professional cleaning with a special heat exchanger washing station pays off: the parts are washed from the inside to a shine, and the equipment works much better. But if you want, you can always save money and do the same yourself. The result will not be worse, and you will have to invest only your own time and effort.

Professional device for flushing heat exchangers

Methods for cleaning the gas boiler heat exchanger

There are two main types of flushing the gas boiler heat exchanger - with and without disassembly of the unit. To disassemble the equipment, you will need tools. What exactly - it depends on the design of heating equipment. In some cases, it is generally impossible to remove the heat exchanger, but you can access it by removing some of the parts.

Before starting work, prepare the equipment:

  1. Disconnect the boiler from all power sources, drain the water from the system and expansion tank. To drain the coolant, special fittings must be provided. If this is not the case, then you will have to turn off the water supply to the house, and then drain it from the system into pre-prepared basins and buckets.
  2. When there is no water left in the system, you can proceed to disassemble the equipment. First, remove the front of the case to gain access to the heaters. If the boiler is double-circuit, then the heater of the second circuit is located closer, the main one is further. To remove it, you need to disassemble the combustion chamber.
  3. Construction details are usually contaminated. Outside, it is advisable to rinse them with special compounds that remove soot and soot. If there are no such products, you can take the traditional household chemicals that are used to wash stoves - gels, cleaning pastes, etc. They should be used only in extreme cases, since even the most aggressive household chemicals are not able to wash carbon deposits as well as specialized ones, but they can damage materials.
  4. From the inside, the elements of the unit can be washed with a strong aqueous solution of citric acid. It does not corrode metal, but it removes plaque and lime deposits well. Most often there is a lot of scale. It is not possible to cope with it by half measures. In this case, equipment for flushing the heat exchangers of gas boilers will be required. Can be made by hand easy installation with circulation pump.

Soot and soot on heater parts

There are three main ways to clean boilers: manual, hydrodynamic, chemical washing of boilers. Let's look at them in more detail below.

Option #1: Do-It-Yourself Manual Cleaning

Manual is the cleaning of boilers without the use of special mechanisms. You will need only simple tools that are in almost any home. The boiler must be partially dismantled in order to gain access to the heat exchanger and remove it. Next, you should decide how best to remove the dirt - mechanically or using chemical solutions.

If it is decided to remove plaque mechanically, you should stock up on a scraper, brush and vacuum cleaner to remove small particles of deposits. If chemical descaling of boilers is planned, then you can use a solution of citric acid, or even better, buy a specialized product.

Trademarks MasterBoiler and SVOD TVN Professional have proven themselves well. They are issued in different forms. There are liquids that do not require special preparation before use, and powders. When using, read the instructions carefully. Some formulations foam, and you need to be prepared for this.

How to flush a gas boiler from scale? Almost all compositions are suitable for removing calcium carbonate deposits, and only individual preparations cope with iron oxide deposits. When buying a product, it is important to make sure that it is designed specifically for the types of deposits that are typical for a particular boiler. Of the popular preparations that remove iron oxide plaque, one can advise the REDD TVN Extra.

Advice. When disassembling and cleaning the boiler, try to be extremely careful not to damage the parts. Installing them in place after manipulation, check the tightness of each connection.

Option #2: Chemical Wash

Boosters are often used to flush boilers. These are special installations that pump liquid into the channels of the heat exchanger. You can make a booster for flushing heat exchangers with your own hands by connecting a circulation pump so that it drives the acid solution, flushing the equipment from the inside.

A good flush can take up to 10 hours if the channels are very dirty, but usually takes much less time. Cleanliness indicators: carbonate and iron plaque completely disappears, and the inner surfaces of the channels shine. To neutralize the residues of acid preparations, special compounds are used, they are poured into a booster to flush the heat exchangers at the end of the procedure.

Option #3: hydrodynamic cleaning

Hydrodynamic flushing of boilers and heat exchangers is similar to chemical flushing, as it also uses pumps and acidic solutions. The main difference is that the liquid is pumped under high pressure. Sometimes abrasive preparations are used as cleaners.

Since deposits are destroyed under the influence of water hammer, the procedure itself is quite dangerous. If the pressure is higher than allowed, the pipes can be damaged, and their repair will cost a serious amount. It is better not to take risks and entrust this work to professionals.

Condition of the heat exchanger before and after cleaning

Do-it-yourself cleaning from soot and soot

Soot and soot hinder the operation of heating equipment. There are models that automatically turn off in such cases. If this does not happen, then combustion products can enter the room. Harmful gases can poison the residents of the house, so it is important to clean the boilers in time to prevent such situations.

Work order:

  • Prepare tools: brushes, screwdrivers, open-end wrenches (keys 8-17 are most often suitable), needle, brush, rags. If a complete cleaning of the channels is planned at the same time, a means for flushing the gas boiler heat exchanger will also be required.
  • Shut off the gas, remove the front wall of the boiler, disconnect the wires, ignition electrode, burner tube. During cleaning, it is advisable to immediately replace the pilot burner gasket.
  • Next, you should get the burner, swirlers. They and the surface of the heat exchanger are cleaned with brushes - soft and for metal. From the inside, the channels are blown with a vacuum cleaner.
  • It is convenient to clean the burner with a brush and a needle smaller than the diameter of the burner hole.

Advice. Do not try to widen the burner hole with a thicker needle. It will be easier to clean next time, but the performance of the heating equipment may deteriorate.

DIY booster

  • When cleaning and washing the heat exchangers of gas boilers with your own hands is finished, the equipment is assembled in the reverse order. First, the burner, nozzle, tube are put in place, the ignition electrode is connected, etc.
  • The assembled boiler is tested. It is turned on and the tightness of the connection of tubes and burners is checked. If the equipment is working properly, it can be put into operation. If there are any failures, then the boiler will need to be disassembled again and the connections sealed.

Video tutorial: do-it-yourself disassembly and cleaning of a gas boiler

The article proposes do-it-yourself options for flushing the gas boiler heat exchanger and video materials demonstrating the procedure. It is desirable to carry out all these procedures at least 1 time in 2 years, and cleaning from soot - once a year. Best time before the start of the heating season. As a rule, the equipment is cleaned and checked at the beginning of September, because. often by the end of the month it gets colder and you have to turn on the heating at least for the night.

Attention! If you are not sure that you can handle flushing the gas boiler heat exchanger yourself citric acid or special tool, contact the experts.

During operation, a thick layer of scale forms on the walls of heat exchangers, as well as limescale. As a result, the efficiency of using boilers and other heating equipment is significantly reduced. To return the heating system to its capabilities, you can use in modern ways cleaning pipes and radiators with flushing units. The main task of installations for flushing heat exchangers is to ensure the forced movement of the chemical flushing agent supplied to the system, which will remove most of the build-up, scale and various contaminants. The pump is the main part of the flushing system.

When to clean heating equipment

They clean heating and technological systems equipped with heat exchangers, as planned after the end of the heating season, or once every 2 years.

Cleaning is also carried out as necessary - this can be determined by significant deviations from the required indicator for the pressure of the coolant in the system or from temperature data. If you clean the system in time, you can avoid replacing the heat exchanger on the gas boiler. This is a big money saver.

Scheduled flush

Private homeowners clean up autonomous systems much less frequently. But if signs of pollution are detected, the owner should think about the need for preventive maintenance. In the event of a drop in the efficiency of the heating system, not only the “pipe in pipe” heat exchanger (or any other) is washed, but also the radiators, as well as other components of the system.

Signs of pollution

When does a heat exchanger need to be flushed? This can be determined by the following signs. So, fuel consumption increases significantly for frequent stops, heat transfer drops, batteries do not warm up enough. Also, the need for flushing is indicated by the rapid clogging of the filters.

If flushing is regularly performed using installations for flushing heat exchangers, then pipelines and other elements of the system get rid of blockages, as well as violations of the coolant circulation processes.

Low-power cleaning equipment is used for autonomous heating systems in private houses. More efficient pumps for flushing heat exchangers are used in multi-storey residential buildings, office buildings, as well as industrial facilities.

The use of such equipment helps to prevent accidents, failure of radiators, the need for major repairs or complete replacement, and an increase in energy costs.

In boiler equipment, the heat exchanger is a critical and responsible unit. It depends on him the efficiency of space heating, as well as the correct flow technological processes. Flushing should not be abandoned, especially if it was announced by experienced specialists after the diagnosis. Cleaning with a heat exchanger flusher using hydrochemical technology is much cheaper than overhaul or complete replacement of heating equipment.

Flushing technology

There are several cleaning methods that can be divided into:

  • Collapsible.
  • CIP.

Collapsible technology is necessary in case of severe pollution or if it is necessary to replace any components of the system. During work, the heat exchanger must be disassembled, and then each component is subjected to mechanical, hydrodynamic or chemical washing.

Since collapsible cleaning requires certain resources, a method is most often used that does not require the mandatory dismantling of the system. This is a chemical washing technology. If it is carried out regularly, it will help to preserve the properties and characteristics of the device for the entire service life.

The technology is simple and economical. For its implementation, a pump is needed to flush the heat exchangers. It is connected to the inlet and outlet of the heat exchanger. The result is a contour. Next, pour into a special container of the pump chemical reagent, after which it enters the heat exchanger. The flow direction on different devices can be changed both manually and automatically. After flushing is complete, the reagent will be neutralized. It is drained, and the heat exchanger itself is washed with plain water.

Washing Equipment Types

If heating is carried out in a timely manner, this will help get rid of corrosion, scale and sediment. There is a special equipment for maintenance of heat exchangers. There are several types of such installations. We will talk about them further.

hydroflushing

This technology is the supply of compressed air to the heating system along with water. Through high pressure and frequent pulses, small air bubbles actively fill individual areas. This allows you to quickly and effectively exfoliate deposits on the walls of the water heat exchanger.

In this case, compressors are used for cleaning. This equipment allows you to flush the entire heating system. But the process is carried out in stages. To achieve maximum effect, small areas should be washed. Before proceeding to the process, determine the required amount of water and the level of pressure that will be supplied to the DHW heat exchanger or any other.

It is possible to carry out hydroflushing in two ways - flowing and filling method. The first technology involves the complete filling of the system with water. In this case, you need to open the valve of the air collector. After maximum filling, the valve is closed. Then the compressor starts to feed into the system compressed air.

Washing chemicals

They are used to obtain the maximum effect from flushing heat exchangers and heating systems with copper pipes. Chemicals are also suitable for steel products. With installations for washing heat exchangers, red liquids are used, which, reacting with contaminants, change their shade. Depending on the volume of dirt, the amount of the product is adjusted. Along with special fluids, hydrochloric or phosphoric acid is also used. These substances will help to rinse the “pipe in pipe” or any other heat exchanger as efficiently and quickly as possible.

For high-quality cleaning, 10 to 30 percent of chemicals are pumped into the system. The use of aggressive substances allows not only to clean the various elements of the system, but also protects against corrosion, water foaming, and increases the life of the boiler.

Device for descaling "Romantic-20"

This is a very affordable product that allows you to rinse the entire heating system with the highest quality. But it is important to understand that the device is intended for use in systems where the coolant volume is up to 300 liters.

This appliance removes scale and other contaminants. "Romantic-20" has the function of automatic reverse control. The pump power is 1.5 bar, the head is up to 10 meters, and the performance characteristics are 35-40 liters per minute.

"Ropuls"

This installation can be used not only for heat exchangers and heating systems. It effectively cleans the supply systems drinking water. Also, this device is widely used for cleaning water heated floors, solar collectors and other equipment. "Ropulse" removes the effects of corrosion, scale and other contaminants.

"Rockal"

This is a small pump that allows you to effectively flush heating systems and boiler heat exchangers. The device is used for washing steel, as well as copper pipes. The system is suitable for where the amount of coolant is not higher than 300 liters.

With its compact size specifications circulation pumps"Rockal" is quite high. So, the productivity is up to 40 liters per minute. The pump is capable of maintaining pressure up to 1 bar.

Cillit-boy

it modern system equipped with an electronic control function. Pumps of this type are used not only for heat exchangers and heating. They can also be used for flushing potable water systems.

Judging by the reviews, Cillit-boy is the highest quality and fastest process for hydropneumatic cleaning of hot water or other types of heat exchangers. Due to the use of new technologies, the unit evenly supplies compressed air and water. The vibrations are constantly pulsating. Due to this, they pass not only through the pipes, but also clean the boiler from the inside.

Do-it-yourself washing device

As you can see, there is nothing complicated in the design of the washing station. This is a pump, a reservoir resistant to aggressive chemicals, as well as hoses for connecting to a water heat exchanger or to a heating system. Therefore, you can assemble this installation with your own hands.

Booster

Boosters are devices for chemical washing of heat exchangers in boilers and columns, any radiators and for cleaning the heating system. The operation is carried out without the need to disassemble the system. The installation consists of three parts:

  • Pump.

There are systems without TENs. However, they are of low efficiency. Let's see how to make a booster for flushing heat exchangers. The first thing you need is a tank. A plastic canister with a volume of 10 liters or more can act as a container. You will also need ½ or ¾ inch hoses and a pump.

Make a booster based on the type of pump. This may be a submersible element or a separate pump. In the case of a submersible, no holes are needed in the tank. A hose is attached to the pump, which is connected to a heat exchanger. The second is taken to the tank. The main thing is that the pump can withstand acid exposure - there are a number of chemically resistant devices.

A remote pump is more convenient for these purposes. You can apply even the most ordinary circulation mechanisms for heating systems. To connect to the tank, you need to use a spur. It is connected to the bottom of the tank and then clamped with nuts. All connections must be tight. Then a coarse filter is installed on the drive. Behind him, the second hose is connected to the heat exchanger. This is how the system is cleaned.

The disadvantage of such devices is the absence in the design of the heating element. Flushing with cold reagent will take much longer. Also it is more high costs for electricity.
