Despite relative reliability, specialists note several of the most common causes of refusals of heating units. The most common flow of the coolant caused by a crack in one of the heat exchanger section. Repair is to fully replace the deformed section.
Causes of cracks:
It should alert the owner of the cast-iron boiler regular drop in the system in the system. These signs can also testify to the formation of microcracks on the walls of the boiler.
Often, restoration work requires a preliminary disconnection of equipment from the general heating system. For this you need:
Work on cleaning or replacing sections begins with hanging a cast-iron boiler. Further process of diagnosis, cleaning, replacement, crimping, flushing should be made using special devices by experienced masters.
Only experts will be able to correctly install back-free equipment, to take new sections to the plunders and levels, adjust the operation of the burners and other important nodes. Incorrect assembly and adjustment of the heating system can create an emergency.
We provide services for the repair of cast-iron boilers of any manufacturers. For this, our company has all the necessary conditions:
All together it makes it possible to perform work quickly, efficiently and inexpensively. Immediately after placing the order, we leave for the address specified in it and return the cast iron boiler into the working condition.
The cast-iron sectional boiler of any type is collected from individual sections. On the destination and configuration, there may be windy, medium and rear sections of cast iron boilers. The assembly is made on loosening nipples (the steel boiler sections are collected on welding). When installing section boilers and auxiliary equipment A significant amount of work falls on horizontal and vertical transportation of individual parts, packages, nodes or units. These works are carried out with rigging means, of which, first of all, the booms should be recommended. In the case of their absence, you can use jacks, winches, hoists, etc. The boiler sections can be collected in packets directly on the walls of the furnace chamber, as indicated in the ch. 2, packages can also be prepared outside the object and after the test is delivered to it (Fig. 2) and installed in the design position using rigging agents.
In all cases, it is necessary to strive for a packet method of installing section boilers. However, in practice, the installation of boilers from individual sections still takes place, so the technology of their installation is set below.
After accepting the construction part on concrete foundation Put the walls of the red brick furnaces to the level of gravy beams and install gravy beams; Next, the walls of the furnace are laid out of refractory bricks to the note of the sections of the boiler. Simultaneously with the walls of the furnace lay the outer wall of the gas plant to height, a slightly smaller height of the firebox wall. Red brick lay with sutures on clay solution, and refractory bricks - on a solution of refractory clay, mixed with chamoten powder. Bor is laid out of red bricks on a clay solution. At the end of the end of masonry, the firebox is arranged for the convenience of mounting the boiler.
During the production of these works, the locksmith prepare the boiler for installation: cleanse sections from molding ground, washed with kerosene nipples and nipple nests, having previously cleaned them from rust, and transport sections to the boiler room may be close to the place of assembly. At the same time, the rigging tools for lifting sections are prepared and assemble.
Before installing each section in its nipple holes on one side, light blows through the wooden bar insert nipples, blurred by graphite, mixed on a natural olife. The sections are then alternately installed in the design position, and each subsequent section of the nipple holes are put on the nipple of the previous section. The outer surface of the nipples is covered to the cone, which eliminates the possibility of slipping the nipple in the nipple socket and creates a seal of the type "metal about metal", which prevents the seeping of water. However, in practice, nipple lubricates graphite paste and the harness from the cord asbestos, impregnated with sudial or graphite, mixed on a natural olife is wound on it. The slim harness of the cord asbestos creates a more reliable seal.
When assembling the sections of the boilers, special attention should be paid to their stability. Stability of a gradually collected package can be achieved using temporary stops. In this case, the rear sections, which always begins the installation of the boiler, fasten the bar and raise the base. The rear sections installed in the design position are fixed by temporary stops to the floor or wall, depending on local conditions. After that, the lifting mechanism alternately raise individual sections of the right and left packets and are connected to each other on the nipples. Thus, in parallel, both packages are collected.
Recently, the assembly device shown in Fig.3 is applied; The assembly with it simplifies the installation and makes it safe, since stability is obtained more reliable. The mounting device consists of racks 1 and 2, the riglel 3 and the console support 4. When assembling the device first, the middle rack 1 is installed on the bottom, then the rigleel 3 is put on and fastened with bolts at height, slightly exceeding the height of the boiler, after which the beelel is coming Extreme racks 2 and also fasten bolts. Next, fix on the middle rack the console support 4. The device is collected on the site of installing the first middle sections of the rear part of the boiler, which, after the assembly of the assembly, is installed in the design position, evaporate and fixed with screw grips. 5. Set the extreme rear sections and further installation are produced similarly above. The device shown in Figure 3 can be used when assembling section boilers of any type.

Over time, the heat exchanger is wears, corrosion and scale do their job. However, its complete replacement of the heat exchanger is inexpedient, since it is usually separate sections, it is necessary to replace the pig-iron boiler section, in which a crack appears. The repair of the section does not give the desired effect - due to the constant temperatures of the cast iron of the welded seam after a short time, it is destroyed.
In some cases, the crack can only be detected when the boiler is diagnosed. Therefore, a specific technique is used with a crack, which increases destruction. At the same time, if you do not want the boiler to be completely out of order, then the problem needs to be addressed immediately after detection.
The price of the replacement section of the cast-iron boiler depends on the model of your equipment, its capacity, the complexity of the works. The final price can only be determined after the visual inspection of the place of work by the master.

After assembling and crimping the heat exchanger, if the hardware device is not required (wagon-6m boilers and similar) boilers will be ready for operation as usual. The work performed is provided with a warranty from 6 to 12 months depending on the manufacturer of the boiler.
Details: Repair of cast iron boilers of heating do it yourself from the present wizard for the site site.
The technology of eliminating damage to the compartments of the cast-iron heat exchanger is dictated by its device. N robust repair is solved replacement of the boiler section . The heat exchanger is a prefabricated design. Elements are assembled into a single unit by means of components (connecting conical nipples). The integrity of one of the sections leads to the failure of the entire device. What are the causes of the occurrence of destructive deformations and the flows of the heat exchanger?
A bit of theory - what phenomena cause the destruction of the heat exchanger?
Heating devices from cast iron are more durable compared to steel counterparts. Cast iron is less corroded in the aquatic environment. therefore gas boilers From this material almost do not rust. However, cast iron (in contrast to steel) is more sensitive to local temperature peaks. To preserve physical properties The designs negatively affect the effect of cold water on the heated metal.
These situations arise in violation of service rules:
The device's clogging leads to overheating of individual small sections of the cast-iron surface.
Feeding on working a gas boiler Cold coolant creates contrast temperatures.
Incorrect burner setting disrupts the overall thermal mode.
These phenomena lead to the appearance of the so-called. "Thermal shock" metal. As a result, one or several elements are deformed relative to others or simply burst.
Common breakdown during operation - to flow the device. There may be several reasons for this: microcrack in the body of the structure, drying sealing sealant. Then the need arises cast-iron boiler sections . For repair, it is better to invite specialists from the service organization. Such companies are carried out regularly. To build devices, they have a professional tool.
emonst is performed in stages. It begins with the diagnosis of body body and ends with a test and launch. Intermediate operations:
Dismantling of the casing and the searched disassembly;
Replacing the Cotele section and screed all elements;
Connecting the device to the heating system;
For diagnostics, the device stops. After cooling, the casing and the layer of thermal insulation is dismantled. The nature of damage and the number of compartments to be replaced is determined visually. If the leakage is caused by a microcrack, and detect the location of the defect immediately fails, the water pressure increases to 2 kg and leave one day.
The splitting on the sections is neatly produced by mechanical path.
At the same time try to strike only on a defective element.
Followed by cast-iron boiler sections . Neighboring with damaged elements are inspected for timely detection of clogging. They are washed or replaced by new ones. Sometimes the masters decide to assemble the unit and then wash it with water with chemical reagents.
Before tie, all surfaces of the contact of the elements between themselves are carefully cleaned. Sealing the path of passing the coolant with new nipples and lubricate their special paste. After replacement of the Boiler section The smoke tract is also compacted. To do this, cover the joints of mastic or tighten with their cords.
The screed is performed using a special tool.
It is very important to prevent skeur and accurately connect the sections.
When replacing several elements, they are added to the collected design strictly one.
In the next step, the device connects to the system and is subject to crimping. For this operation, the maximum pressure allowed by the manufacturer is supplied. For each model, this parameter is specified in the passport.
Repair of cast iron heat exchanger Required without explicit integrity disorders. When the heat carrier pressure regularly drops in the device and it is often necessary to focus with water. The reason for this behavior of the boiler is hidden in the appearance of microcracks in the furnace. At high temperature, the liquid has time to evaporate and removes with smoke gases. Unstable work - a valid reason for contacting the service.

Homemade heating boiler
In addition to buying the heating boilers presented in the market, well-known and not very global or domestic manufacturers, there is always the opportunity to make a boiler heating own hands. And to save at the same time the list of options, without which your heating system can well do. All you need for this - knowledge of the device and the principle of operation of your chosen type of boiler, materials, tools and equipment, as well as practical skills to work with them.
If you wish, you can build almost any type of heating boiler. The main thing is to make the right choice, and for this you need to know the main advantages and disadvantages of the most sought-after types of heating equipment. AND so, the boilers of heating are:
The manufacture of boilers of this type is not recommended independently: the gas equipment is presented technical requirementsthat you hardly succeed in satisfying in handicrafts.
Household electric boiler
Pretty high popularity of this category of heap block boilers is explained by simplicity of design and relatively low security requirements for installation and operation.
A huge lack of electric boilers - high electricity prices. As a result, such equipment is used to provide periodic heating, such as cottages or garages.
Homemade liquid fuel boiler
The design of such a boiler does not differ in high complexity. However, the cost and subtleties of adjusting the nozzles feeding into the combustion chamber will make any at least twice think before reaching the creation of a heating unit operating on a fuel oil or diesel.
Boiler long burning do it yourself
Representatives of this type are optimally suitable for heating both private homes and various objects of the commercial or industrial sector. High efficiency and versatility in use provide solid fuel boilers the highest demand in the market.
According to the principle of operation, solid fuel boilers differ in wood, pyrolysis, long burning and pellet. The most popular for independent manufacture An option is long-burning boilers, while pyrolysis and pellets due to the high cost of individual components are used much less frequently.
To which the design of the heating boiler will be, there are several conditions:
The greatest durability demonstrates the heat-resistant stainless steel. However, it is she who has the highest price in the market, and its processing is a rather difficult task with which not to cope without special equipment. The same applies to the cast iron, which, however, is worth much cheaper than stainless steel. Traditionally, for the manufacture of heating boilers, leaf steel with a thickness of 4 mm is used - this option is relatively easy to handle and, most importantly, is quite reliable and durable.
To ensure the natural circulation of the coolant, it is necessary to use the contours of heating and the binder reinforcement of a large diameter, and cumulative capacity Place at height. If there is no such possibility, you will have to use the circulation pump - it will reduce the diameter of the pipes. However, pump system Heating boiler is an energy-dependent, which must be considered when choosing a design and functionality aggregate.
No pipes that will be equipped with your boiler should have a diameter of at least 32 mm - a thick-walled steel pipe is suitable for their manufacture. The heating circuit should be made of galvanized steel, not forgetting the sealing of threaded connections.
Homemade boiler on firewood
The cheapest option for self-making is a wood boiler. Structurally, such an aggregate is two capacities placed one to another. Internal performs the function of the furnace, an external - heating tank. The design of the wood boiler is really simple, and it will be able to work not only with firewood, but also other types of solid fuel.
The design of the wood boiler includes:
Device of a solid fuel boiler
Large minus wood boiler - low efficiency, that is, a huge consumption of firewood or a constant lack of heat in the house.
Pyrolysis boilers are more expensive in the manufacture: they have two combustion chambers - for fuel and for pyrolysis gas, and some of their components and themselves are very noticeable. Nevertheless, such equipment is in great demand in mind its economy - it completely pays off throughout 3-4 seasons.
The classic pyrolysis boiler scheme includes:
Pyrolysis boiler work principle
Pellet boilers were invented at the end of the 20th century. They function on pressed sawdust, and their basic principle of operation lies in heat transfer from gas allocated during the combustion of the latter, which heats the coolant in the heat exchanger.
Boiler heating on pellets do it yourself
The design of the pellet boiler includes:
In pellet boilers, it is best to use cast iron heat exchangers: they have a higher heat transfer indicator and are not subject to corrosion.
The main element of the electric heating unit is the thermoelectric heater (TEN) - it is necessary for the transformation of electricity to heat. The electrocotel housing can be made of any material, and the nodes necessary for its operation are regulators, sensors, etc. - can be bought in any specialized store.
Device electric boiler heating
Structurally electric boiler consists of:
Principle of operation of the electric boiler heating
The coolant in the system can circulate both naturally for which it is necessary to provide a height difference between radiators and a boiler tank and forced with a pump. The easiest version of the electrocotel is the installation of the Tan directly into the heating system. If such a design is not suitable, you can construct an electric boiler with a removable nozzle - it will provide an opportunity to quickly reach the Tan if you need to repair or replace.
The optimal solution for heating, say, a small cottage is a separately located electric boiler of small sizes. The pipe of such a boiler will have a diameter of about 220 mm, and the length of the case is no more than half a meter, which allows you to install it almost anywhere, of course, taking into account the security rules.
The housing of the electrocotel should be sealed. It is supplied with a hole for the receipt of the heated coolant into the heating system, as well as a pipe for the return supply of cooled water.
In addition to solid fuel and electric boilers for self-making, a number of alternative heating units are suitable:
Represent transformers consisting of primary and secondary winding. In such a boiler, electricity on the outer winding is converted into a vortex current, and the created magnetic field is transmitted to the inner, which gives energy to the coolant.
Save thermal energy condensate, therefore they are considered more efficient than gas and even solid fuel. Condensation of steam occurs in a heat exchanger with a special design - it is it that provides such boilers 15-20% of the efficiency in front of traditional gas equipment.
Such aggregates evaporate through the work, after which it burns its pairs. The energy obtained in this way is transmitted to the heat exchanger, which heats the heating system thermal agent. The equipment of this type has two essential drawbacks - low efficiency and a large number of semissions into the atmosphere.
This equipment is universal in use, however, for its independent manufacture, there must be short-sighted skills and excellent knowledge of the principles of work. different species Heating equipment. Separate components of such aggregates can cost quite expensive, but in general the combined boilers are capable of paying off for no more than 5-6 seasons.
When making a boiler of any type, it is necessary to be guided by the requirements of the safety rules and the categories of the heating equipment of the standards with respect to the chosen category of heating equipment.
A gas boiler complex mechanism. It can be divided into 3 Main parts: Electronics, gas pipes Burners, heat exchange knot (pump, tank, fan). You can only repair only the last part.
Attempts to restore the first two parts, without due skills, lead to the final breakdown Boiler, gas leakage and other negative consequences.
Gas boilers rarely break. This happens as a result natural wear equipment or because factory marriage. Other cases of breakdowns are necessarily related to the following factors.
The boiler may break due to water. In the risk group, first of all, there are two-circuit devices used not only for heating, but also for hot water.
The fact is that rust From the pipeline, other fractions, thin heat exchanger tubes are littered for the year.
Avoid troubles related to water quality will help filter rough cleaning. It is installed when installing on the feed pipe liquids. For more security, you can add to the system small-grained filter, or establish a full-fledged cleaning system.
Household appliances resistant to voltage and disconnect electricity. But the gas boiler is a thinner equipment. Voltage jump will turn off the boiler or breakage of electronics. The malfunction of the device or turning off the electricity will damage the heating pipes.
In order to avoid sad consequences set at least one of the additional devices.
Photo 1. Electronic resanta voltage voltage stabilizer for heating boiler. The device is attached to the wall.
Attention! When buying a generator, check if it really single-phase.
Installation of complex equipment nonprofessional He will entail hard consequences. In frequent cases, the following problems arise:
If the installation of the gas boiler is performed correctly, operational problems occur only because of weather conditions . Cold in winter, a desire to warm up pushing people to use the boiler in the maximum mode. Equipment Such conditions can withstand, but there is no gas system. Reducing the fuel pressure leads to interruptions of the device. Automation starts off the boiler. The problem is that it is it is impossible to call breakdown And it will not be possible to eliminate it.
A specialist should fight with any malfunction of the gas boiler. However, the ability to use the services of the master is not always, and breakdowns are empty. Consider problems that are solved on their own.
Usually the smell of gas appears when it leaks from a threaded connection of the feed hose. If indoors where the boiler is installed, the smell appeared, you need open the window and turn off the boiler. Next, act according to the instructions:
Attention! When the place of leakage could not be detected, overlap gas, call a specialist.
If during the boiler disappeared or decreased sound published turbine - indicates a malfunction of the fan blowing. For repair it will be necessary: shipping, new bearing, rag, thick lubricant.
The turbine may also not work because reduced voltage network or control board faults. The first is eliminated using the stabilizer, but the second only by calling a specialist.
Chimney problems arise only u Boilers outdoor type. This is due to its size and vertical position. Attachments do not need to clean the chimney.
Chimney, consisting metal partsCleans with a metal brush. It is necessary to disassemble and mechanically remove the accumulated soot. Whole chimney clean special vacuum cleaners or chemicals. But for this you need to call a professional.
Photo 2. Three ways to improve the chimney for an outdoor gas boiler. The first option is to clean the most difficult.
Overheating boiler is associated with contamination of heat exchanger. To clean the device, you will need: special soloic acid solution, adjustable key, fum-tape, metal brush. Next, act according to the instructions:
Problems usually arise with electrode burning. If the flame burner fucks after a few secondsAnd the boiler gives an error, then the problem is in the combustion sensor. Turn off the boiler, overlapping gas.
For the repair of the electrode will be required sandpaperwith which sensor probes are cleanedwithout removing it. If the breakdown remains - the sensor changes.
Exist two problemswhich lead to spontaneous shutdown of the boiler. The combustion sensor broke or smoking chimney. Repair of both faults is described above in the article.
Look at the video in which it is described about the malfunction arising from the operation of the boiler.
Most of the boiler breakdowns are eliminated independently, but this does not mean that you need to neglect the help of a specialist. Gas equipment Potentially dangerous for life.
And also do not forget about maintenance . Cleaning the heat exchanger and chimney will keep off from possible breakdowns.
The reasons why the flow of the boiler is not really so much. First, corrosion can be the culprit. What is corrosion is the destruction of the metal structure under the influence of the external environment. The internal corrosion of the gas boiler is due to the effect of oxygen in water, external combustion products.
The next reason for the leaks can be the low quality metal, from which the heat exchanger and the quality of the seams of its connections is made.
High pressure in the system, or the hydroworks also cause leaks in boilers. Traveling the walls of the heat exchanger also gives to flow.
In some cases, when water drips from the boiler, and you think that you have a drift boiler, in fact, it can be a condensate from the chimney that flows along the chimney pipe and hits the burner. If such a situation happens often, it is necessary to equip a moisture assembly glass in the chimney. When dripsing near the circulation pump, the bolt was unwound, located on its center. Two bolts.
Let us consider in more detail each case separately and describe what to do if it happened.
Heat exchangers installed in heat generators can be made of copper, steel and cast iron. Each of them has its pros and cons. Copper heat exchangers are resistant to corrosion and durable, subject to the proper operation of the boiler. Steel heat exchangers are the most common, due to low cost, resistant to thermal stresses, due to its plasticity, but are often subject to corrosion.
Corrosion of heat exchangerCast iron is resistant to corrosion, have a long service life, although it is afraid of the temperature drop and hydrowards. Most of the manufacturers do not use anti-corrosion coatings. But in the latest models of gas dual-circuit boilers Ferroli (Ferroli) steel heat exchangers Covered with anti-corrosion aluminum coating with ecological internal insulation.
On BAXI (Baksy) units, copper heat exchangers are covered with special corrosion makeup. Protherm (Proterm), Budrus and Beretta have a cast-iron heat exchanger, which is covered with a special composition from corrosion. In addition, such a heat exchanger consists of individual sections that can be changed in case of damage, without changing the entire heat exchanger.
Wall Boilers Rinnai (Rinnai), Celtic (Celtic), Bosch (Bosch) are equipped copper heat exchangers, Vaillant (Vailant) and Navien - stainless steel, it is believed that they are less exposed to corrosion.
The formation of corrosion is a great influence of a frequent boiler feeding. In the ideal embodiment, the so-called "dead water" should circulate in the heat generator, without an oxygen content. It is oxygen that contributes to the formation of corrosion.
If you often have to feed the heat generator, the reasons for the pressure drop in the unit should be eliminated. Oxygen corrosion forms an ulcer heat exchanger on the inside of the heat exchanger, which is very dangerous. Well-inside, it forms a cross-cutting rust and destroys the heat exchanger.
The strength of the boiler depends on the quality of the welded joints. If there are cavity, irregular seam on the weld, sooner or later this seam can give to flow. Particularly dangerous is the void, which is inside the seam. Ideally, the seams should be shifted by the X-ray apparatus, but not all manufacturers do it.
Although heating boilers They are vessels working under pressure and have an increased requirements for manufacture, marriage sometimes happens. And, as a rule, dripping from the heating boiler after the end of the warranty. Rave the boiler inside and stop the flow does not always succeed.
It depends on how the heat exchanger is arranged. In models where the bitermal heat exchanger is installed (secondary and primary are in one case, heat exchange occurs due to the design of two in one) to do it problematic. But even if you did it, as practice shows, it will not help you for a long time.
Excess pressure in the system can also trigger the flow of the boiler. The causes of high pressure may be many reasons. The main reason may be a malfunction expansion tank, air traffic jams in the system, clogged mesh filter, safety valve fault, fuse crane.
The fault of the safety valve says constantly leaking fluid from the tube. High pressure can not only give a crack in the boiler, but also to cause an explosion. Watch out for the health of the pressure gauge and the reset valve, sometimes the valve encourages the layer of salts due to it. Rinse it in citric acid.
Heating Boiler Safety ValveIt is necessary to regularly check the compliance of the pressure on the valve and in the expansion tank. When installing the expansion tank, it is necessary to calculate the volume of the coolant. How to calculate - there is a calculation formula, and the mean value of -1.5 atm or 0.2 atm is lower than in the system. For prevention, do not forget to wash the filters at the inlet and outlet from the heating circuit, after feeding the system, you need to be lifted the batteries.
The cause of the flow can be the sampling of the combustion chamber. Steel and cast iron burn out when carbon is injected from their composition, so the metal on the combustion chamber is thicker. As a rule, the squeak occurs when the height of the combustion chamber is incorrectly installed, the burner's incorrectly displayed, the burner is not adjusted for the minimum and maximum power, too high flame.
The fire happens when the boiler is constantly working at maximum power, this happens in case of insufficient housing insulation or when the heat generator is selected without taking into account heated area.
By purchasing the boiler, read the reviews on the Internet and prefer positively proven manufacturers. It is better to buy a heat generator a little greater power, with reliable flame modulation and configure to be entrusted to specialists.
How to repair the place of the leaks - the leak elimination algorithm is the same on solid fuel boilers, such as Don, CFM, and gas, for example, on AOGV, Alixia 24, Ariston (Ariston), Deu, Ardery, Electrolux.
What the heat exchanger looks like - it is a metal or pig-iron body, heated by the flame of the burner and transmitting the thermal energy of the liquid, which is inside it.
To disassemble it and spare it yourself, you need to remove the front panel, protective casing and protection of the combustion chamber with a long screwdriver. Then disconnect the wires of the sensors and the pipelines suitable to the heat exchanger, try not to damage the nozzles and tubes, hold them with the key.
In order to connect everything correctly, it is necessary to first take a picture of the insides of the heat generator. Then disconnect the fan and the smoke sensor. Removing the heat exchanger, do not use force and do not make sharp movements, do everything extremely carefully.
If you discovered a breakthrough between the contours in the tube - it is impossible to close this hole, the heat exchanger will have to change. The heat exchanger cannot be welded, you should apply a gas burner soldering.
Soldering heat exchangerIn order to make a soldering with your own hands, you must first clean the place where the fistula was formed. You can do this with shallow sandpaper. Soldering is produced by a gas oxygen mixture with a solder containing the same chemical elements from which the heat exchanger is made.
It is impossible to apply tin in this case, since such a repair again will again lead to the formation of a fistula. After soldering, a protective coating should be applied to the problem space, for example, a layer of aluminum.
When buying a heat generator, carefully view the quality of the soldering of the connecting seams, both on water and on the primary heat exchanger, there should not be in the influx, irregularities.
Perform the burner setting in accordance with the instructions in the instructions. To avoid the appearance of fistulas, it is necessary to take measures in a timely manner if high pressure and enforcement in the system. Avoid frequent feeding system with water, find out the reason for the pressure drop in this case and eliminate it.
✔ Feedback Rate Article:Often homemade boilers are better than manufactured by industrial way.
This is due to the fact that not every design can be adjusted under the existing heating system, but to make a pigtail battery boiler that coincides with it in its parameters is quite easy.
Requirements that are presented to the boilers of private house owners, simple:
Given the fact that both gas boilers and a gas pipeline supply to the house cost a lot of money, and the subsequent payment of gas, the same savings will not bring, in many private houses there are devices running on firewood. The most effective view of the heaters is a water boiler that can not only warm the small vacation home Or a cottage, but to supply it with hot water.
The homemade pigtail battery boiler is an excellent alternative to industrial aggregates that are expensive, and there is little saving.
The structure of it is such that a water boiler is embedded in an ordinary furnace, which increases its heat transfer in many times, thereby reducing spending on firewood, and the heated room is almost instant.
Find the old Soviet cast iron batteries today is not a problem. They are demolished in tens of tens when residents of apartment buildings change heating to more modern modelsOr when the old buildings are demolished. The best option for making the design will be cast iron radiators M-140.
In one section of the battery is placed to 1.5 liters of water. The number of sections directly depends on what area should heated the heating boiler from the cast-iron battery. For example, for a house of 100 m2, 12 sections will need 12 sections with a total capacity of 18 liters and the amount of 3 m2.
Before starting the manufacture of the boiler, all the radiator sections need to be thoroughly rinsed from scale and dirt that has accumulated over long years of operation. To do this, you can pour a 6% solution of hydrochloric acid inside and hold it there for some time until it is connecting all sediments. After that, the solution merges, and each section is thoroughly washed with water.
This procedure should be carried out in slower, in compliance with all precautions. In the hands there must be protective gloves, and on the face respirator. After all the sections have passed the cleaning process, you can start collecting a cast-iron battery boiler with your own hands.
Collect radiators together is easy, but it is pre-acquire new intersection gaskets or use asbestos cord instead of them, impregnated with graphite powder, pre-divorced in Olife.
Since inside the boiler, the temperature may exceed +600 degrees, then the gaskets should take care in advance. The tightness of the entire design depends on their quality and strength.
The sequence of the radiators assembly is as follows:
On the one hand, the riser should be the right, and on the other - the left thread. If it does not work, then you need to screw the nipple, and on it a clutch with a Sgon.
It is important not only how they will be collected and connected to heating system Radiators, but also their place in the stove. In order for the device to work for a long time and efficiently, a boiler of the cast-iron heating battery (video shows how to do it) to install not in the furnace, where firewood is lit or coal, and therefore there is an open fire, and behind it in the smoke canal.
It will save the device and will extend its service life, and the heating of the gases that are formed during the combustion of the fuel, no worse than open fire.
Cast iron is a fairly fragile metal, so neither blows, nor excess pressure, nor too high temperatures He will not stand. By installing the boiler from the radiator into the furnace, it is necessary to ensure that the pipe at the outlet of it was perpendicular to the floor, and the return was under the floor and the foundation of the design.
After the boiler is installed, you can proceed to the masonry of the stove walls, after checking it on tightness. To do this, run water on the pressure system.
The furnace can be built yourself by adhering to the sequence of actions.
After graduating from the chimney, the entire furnace must be checked for the quality of work, for which it is flooded.
You never need to stir the oven if there is no coolant in the boiler. It can output a system. You can think and build a design that will work both as a heating system, and as a stove for cooking.
After performing all the actions, you can quite build a stove with a water boiler from cast-iron batteries with your own hands.
