In modern devices, heating can be used various elements. Their composition depends on the variety of coolants and the method of heating. The obligatory component of such installations is the chimney responsible for the removal of smoke and other combustion products from the room. Let's figure it out what it is - coaxial chimney for gas boiler And what is its advantages. For competent installation This design does not only eliminate gary and smoke, but also provides the influx of fresh air.
So it looks like a design for the removal of combustion products
The design of the coaxial chimney for the gas boiler is not as complicated. It consists of two pipes of various diameters, which are installed in each other. In this case, there is a few centimeters between the walls.
Such chimneys are two types:
It works a coaxial installation as follows: on the external highway, the air is closed from the street, then it moves through the pipes and heats up. The air is fed to the furnace already heated, which makes it possible to lower the gas consumption. On the channel from within the smoke is derived. In certain devices there is a system of insulation. In order for the chimney design to work correctly, a high-quality assembly should be carried out. This includes security nodes.
For camera units closed type The chimneys are suitable, the length of which is no more than two meters. This will prevent deunions from the appearance.
Helpful information! Coaxial option can be installed even in wooden buildingSince it is perfectly protected from fire.

Do you know what this technique is so good? In this review, we will consider all the advantages and disadvantages, as well as the secrets of choosing this type of boilers.
Most often, the installation of the coaxial chimney is performed using a direct passage through the wall. In some cases, the device is used through the roof or overlaps. Best location For such a design - horizontal. If the heater is in hard to reach place, the air duct is derived using vertical sites.
Such highways are ideal for parapet equipment and convectors. A coaxial type system can be used with a burner. Steel chimneys are suitable for dual-circuit and single-circuit units. In the manufacture of pipes, stainless steel, aluminum or plastic is used.
For your information! When selecting pipes under gas equipmentIt must be borne in mind that only the designs made by the same manufacturer as the main units are suitable for individual heating devices as the main aggregates.

Coaxial chimney for gas boiler contains such elements:
For the manufacture of installation, acid-resistant stainless steel is used capable of withstanding significant temperature increases. Chimneys are such:
Important information! Many boiler manufacturers advise to mount coaxial equipment with a bias to the heating unit.
The most important advantage of the outdoor gas boiler with coaxial chimney is that fresh air flows allow to maintain the combustion process. When mounting such a device, you will not have problems with excessive dryness in the room. In addition, you do not have to air the rooms often.
The air passing along the installation contour warms up, thereby improving the combustion process. This contributes to greater equipment efficiency. Due to the constant inflow of air - the gas in the furnace chamber is completely burned, which increases the efficiency of the system. Coaxial highway has no such high temperature Surfaces like a traditional chimney.
For your information! It is possible to choose a coaxial type chimney to each heating structure. There are pipes of various diameters and from different types material. Such a device will easily install even an unprepared specialist.
Some rules for mounting a coaxial chimney will help you build a high-quality heating system. Of particular importance is the step-by-step instruction:
The chimney device through the wall does not require special devices and skills. This design is relevant for buildings with an autonomous heating system.
Such chimney elements are easy to install, and also have a high service life. Under the influence of low temperature values, some sections of the chimney design may vary, which affects the efficiency of the entire system. Insulation will avoid such situations. It is important to take into account the features of a specific device when the pipe in the pipe. An effective solution will be a decrease in the cross section of the chimney installation. You can try to make the inner tube shorter. This will prevent condensate icing. The installation of separate pipes made of steel is practiced. At the same time, one will take the air, and the second output combustion products.

The decision to install the coaxial chimney will give good results. And useful recommendations and the application of instructions will help to establish a similar design yourself, without attracting specialists.
Instructions and drawings of solid fuel boilers long burning do it yourself 
As one of the components of comfort and comfort, the house is warm. Today, many ways are known, with the help of which you can warm the housing. For apartment buildings, the decision is centrally heating, while owners of private houses have to install boiler equipment.
Such devices that work with fire must necessarily assume the presence of a chimney device. And if ordinary pipes used earlier, today they replaced a more advanced solution. An increasing number of homeowners resorts to the installation of coaxial chimneys, which have effective.
Coaxial pipe provides for the presence of two nodes, one of which is inserted into another. The design has two contours that have different diameters and are located on the principle of Russian nesting. Inside there is a jumper, which eliminates the contact of the parts.
Such a device is mounted in a heat generator, which has a closed combustion chamber, the gas boiler should be attributed to it. The coaxial pipe has such a device that the inner tube is used to derive combustion products to the street, while the more impressive pipe diameter, which is located outside, is used to supply the oxygen required to ensure combustion.
The standard chimney of a coaxial type has a special device, it allows you to solve the tasks, one of which guarantees the combustion process, the other - provides air intake. The length of the device does not exceed 2 m. Typically, such structures are located horizontally, but are outlined through the wall. Sometimes there is a coaxial tube, which goes through the roof and ceiling overlap.
The design of the chimney described allows it to work according to the principle that differs from the usual one. Required for burning oxygen enters the equipment outside. This eliminates the need for a constant inflow of air into the room by ventilating method, which is traditionally for conventional smoke channels. Among other things, several more problems are quite successful, which are characteristic of traditional chimneys, among them:
Coaxial pipe reduces heat losses due to the fact that the air incoming outside heats up from the discharge internal hot pipeAs a result, it is possible to achieve a higher efficiency. The risk of fire is minimized, this is especially true of areas that come into contact with the discharge channel and flammable surfaces, because the inner tube is cooled to a safe temperature when it gives the heat that is located outside.
Such chimneys for gas boilers provide complete fuel combustion, and unburned particles are not thrown out and do not contaminate the atmosphere. Equipment equipped with coaxial chimney is characterized by environmental friendliness. Due to the fact that the processes on the type of combustion, gas removal and oxygen flow occur in a closed chamber, the operation of the equipment becomes more secure for humans, combustion products that could represent the danger of health, no longer enter the room. This also indicates that the ventilation system is not required.
Chimneys for gas boilers have enough compact sizes, it will additionally saves space. Having visited the store, you can find such structures that are presented in a wide range, certain models are used for systems, different in power.
To date, two ways are known for which the installation of a coaxial chimney may be carried out:
The chimney channel will have a direction that is determined by each boiler individually. It is important to take into account that horizontal designs are designed exclusively for those devices that have forced ventilation. If you look into sanitary standards and rules, then you can find out that the horizontal area must have limited length, its maximum value does not exceed 3 m. But some manufacturers install other restrictions for their products. Therefore, before designing structures, it is necessary to familiarize yourself with the characteristics of the device.
Gas coaxial pipe is located vertically, if there is no possibility to equip the channel output through the wall. This case applies to a small width of the street or the close location of the windows. Coaxial chimney can navigate and obliquely.
Installation work should be started after it is possible to choose the device properly. If we take into account the installation rates of the internal chimney, then the output diameter should not be greater than the diameter of the discharge channel. This moment should be controlled by referring to the data of the chimney passport, where you can find it diameter.
Coaxial pipes for gas boilers are connected to the equipment with a pipe, a tee or knee. Each subsequent element must be fixed to the previous one in such a way that obstacles are not created for the removal of combustion products.
The list of items that will be required for the installation will depend on where the outlet is located at the top or side. In the first case, the chimney is to bring much easier. For the second option, you need to use a horizontal design, displayed using modifications and brackets to a vertical position.
To install the pipe, you need to apply the transitional node. Clamps are fixed to other elements in a hard way. The use of adapter or extension cords of self-made production, putting the ribbon and applying the sealant is invalid, because these options will not only be unsafe, but also unreliable.
When installing the chimney it is important to remember that the outlet should be higher heating device 1.5 m minimum. Pipe conclusions must have an angle of 3 °, which will ensure the unobstructed condensate output. Coaxial chimney is best spaced over the surface of the roof of 1.5 m, otherwise it may be clogged.
If it is assumed to be equipped with a rather complex system, then the total length should be 3 m. The installation of a coaxial tube should not assume the presence of more than 2 knees. From the nearest windows to the outlet, a distance of 60 cm should be ensured, as for the distance to the gas supply pipes, this parameter should be 1/2 the diameter of the outer tube. Fragments of the facilities must lay down to each other as close as possible, if it is necessary to circle the chimney of the obstacle, then a special knee with different angles of inclination should be activated. You can use two such nodes at once.
The area of \u200b\u200bthe roof is considered to be the most responsible zone, work here must be carried out taking into account fire safety. For this, insulating nozzles are used, as well as non-combustible insulation. Between the pipe and overlap it is necessary to leave the air layer. The chimney canal should not touch the objects, for this, protective covers are used.
If the chimney is displayed through the roof, then this node must be sealing, by protecting the apron, which must close the joint. When the output is carried out through the wall, you need to use non-combustible materials. Coaxial chimney should always remain cold, this feature is one of the main ones.
Frequently often owners of boiler equipment are asked about why coaxial trumpet freezes. In this case, the boiler room can even stop functioning. In order to avoid such trouble, it is important when connecting the boiler try not to ignore the manufacturer's tips. It is necessary to observe the length of the pipe, its location and bias. The presence of a fan will free the camera from combustion products, it will provide a sparseness that is necessary for the new air supply.
Coaxial kits are also distinguished by the material of the manufacture, as well as structurally, so some of them can freeze, while others function normally. If the vertical coaxial pipe frozen, then the problem can be solved partially by removing the plugs that are located in the top of the boiler. The flue gases in this case will go outside, and the air will come from the room.
The plug must be installed on the previous place as soon as the ice melts. After all, it will not be able to work in this mode in this mode. The unit breakdown is inevitable, if the particles contained in the air according to the type of kitchen dust and the soot will fall into the equipment. When icing does not happen so often, this method is quite possible, but with regular frost, you should purchase the "Anail" kit.
Coaxial pipe 60/100 can be purchased by 1500 p. It is an active design that is capable of improving the environmental characteristics of the boiler and its fire prevention properties, while at the same time increasing the efficiency of work. Installation You can do yourself, but if you doubt your abilities, the installation is better to entrust professionals.
Autonomous heating recently becomes not only prerequisite accommodation in a private house, but also by the way of hanging comfort and saving money owners of residential area in apartment buildings. The increased demand for heating devices has become a reason for developing more powerful and productive models. Modern equipment places increased requirements for connecting and conclusion of burning waste through smoking channels. For this reason, the coaxial chimney for the gas boiler has entered, the device of which is fundamentally different from the usual one.
Coaxial chimney is a smoke removal channel, the design of which is two pipes of different diameters, inserted one to another. The inner surfaces of the pipes do not touch each other, between the contours is the air layer. Coaxial chimney is collected from challenges: straight pipes, taps, tees, condensate collections. It performs two main functions:
Important! Such a device is designed on the principle of separation of the chimney function. This allows you to improve performance and efficiency. Fuel combustion products, the temperature is high enough, heat the outer contour. And the external pipe through which the air passes is passed, in turn cools the inner. Thanks to such a design, the temperature is equalized in the chimney, which prevents the appearance of condensate and reduces the risks of the occurrence of fire.
Coaxial chimney is considered more perfect and effective way Removal of combustion products from the furnace of the heating device. Elements for assembly are often supplied complete with equipment. Most manufacturers recommend setting their products with chimneys of this type, as they have the following advantages:
Important! Coaxial chimney is suitable exclusively for gas boilers with a closed firebox and a forced product operating due to a small fan embedded inside the pipe. The project of the smoke removal system of this type necessarily include a condensate collection and a revision through which the pipe is cleaned.
According to the statistics of the Ministry of Emergency Situations and manufacturers, the coaxial channels of smoke removal are considered safer and efficient. However, when they are installed, certain requirements should be followed:
Note! Professional builders argue about the efficiency of using coaxial chimneys on the territory of the middle strip of Russia and the Bole of the Northern Regions, arguing that from developed for use at temperatures up to -15 degrees. Where in winter most Time The temperature drops below this mark, they are frozen. Manufacturers explain the problems in improper calculation of the diameter of the external and inner pipe And the length of the chimney.
In contrast to the traditional methods of smoke removal, the chimney of the coaxial type is mounted simply. To install, you need to strictly follow the instructions of the manufacturer of gas equipment and requirements fire safety. Experienced masters They advise paying attention to the following points:
IN wooden house most often began to use autonomous heating systemconsisting of a variety of elements. Their composition can be modified depending on which the heat carrier is chosen or, as it will be heated. It is worth noting that, regardless of the material used for the furnace, the smoke system should be present in the boiler or, in other words, chimney. The design may have a different configuration, features, and even specifications, however, a coaxial chimney is recognized among many of many.
Coaxial tube for a gas boiler is not just a product, but, having a mass of advantages, due to which it has become so popular. The high efficiency is provided by perfectly heated incoming air.
The compact dimensions are characteristic, since the installation of 2 large pipes is not required, and one is sufficient.
The pipe does not require installation of additional ventilation. Ecology is extremely important for humans, since it is often possible to meet heavy and cheap materials capable of separating toxic substances when heated.
Benefits:
Such a device as the vertical removal of the smoke of the coaxial species is used for the heating system in which the gas boiler is installed, with a closed combustion chamber. The device for direct heating can be in the form of a gas boiler, convector or radiator. The installation of a two-king coaxial chimney should be carried out as correct as possible so that the principle of operation is not broken. Each contour is responsible for its definite task. The first is required for the output of combustion products from the firebox cavity in the boiler. The second is intended for the inflow of air into the firebox cavity, which ensures efficient burning.
Our next article discusses the criteria for the choice of dual-circuit boilers :.
It is in order to be a great thrust and uniform combustion of gas, in the boiler with a closed combustion chamber cost a coaxial chimney, whose length does not exceed 2 m. Otherwise, curvatures that prevent the release of combustion products from the furnace can be formed on the pipe.
In order to establish a heating boiler in which closed camera combustion, it is necessary to install an independent heating system, you can use for individual construction, as well as apartment house or production room. If it is decided to install a coaxial chimney, then it will be necessary to comply with certain rules and requirements so that the device is carried out as correct as possible and without mist.
Requirements:
It is strictly not desirable to install a coaxial chimney tube under the window opening, but if there is no other option, then there must be a distance of 1 m. To eliminate condensate, the installation of a coaxic chimney and a small tilt of the pipe is required.
It works a coaxial boiler, as well as everyone else, in order to pull the room, however why is it so called? Coaxial boilers Received their name due to the installation of coaxial chimneys.
Such chimney performs functions:
The inner cavity is responsible precisely for the withdrawal of smoke. Air is also supplied to the combustion device or, in other words, the air mass is carried out. Due to the air, there is a functioning of the boiler for the cavity of the outer tube.
The chimney for a coaxial boiler must be installed, corresponding to such provisions as the standards standards, carefully thought out, high-quality and working properly. Coaxial chimney differs from the vertical and traditional device to the fact that it is not difficult to install it, and a number of special skills or preparation will not be required, be sure to follow the instructions so that the installation technology has not been broken. Only in this way can be confident that the product is working properly and the penetration of the smoke inside the room is strictly excluded.
Stages:
Installation of coaxial chimney is strictly prohibited to be carried out by means of adhesive tape or sealant. The hole in the wall space must be laid by a special non-combustible insulation.
If forced ventilation is installed in the boiler, then it is necessary to install only that section of the chimney that is horizontal.
If there is a need to make a turn in the pipe, you can use a special swivel knee, and on 1 chimney is allowed to install a maximum of 2 knees. Installation of the pipeline on the wall surface is carried out with the help of brackets, and so that they are necessarily present on each junction. In the end of the coaxial chimney, it is necessary to install such additional elements such as an umbrella, a deflector and others.
Depending on the model of the coaxial boiler, the length of the chimney is selected, but it is possible to elongate if it is permissible technical characteristics. On average, the length can be 3 m. The chimney of the coaxial species has certain advantages, at the expense of which increases its popularity almost every day.
The advantages are to:
Unfortunately, there are disadvantages of such products, but on the background of many advantages, they sometimes go to the background. To carry out installation, you need to coordinate the actions with SanEpidadzor. During the operation of the chimney, the release of toxic condensate is carried out, which is forbidden to pour into the ground, and is direct pollution of the environment. Disposal of such condensate should be carried out in a separate place. If you set the design of such a two-channel type in a house with a variety of apartments, it is possible to perturbation from the inhabitants. If there is no appropriate permission from the organization, it will be necessary not only to remove the installation, but also to pay a fine. No matter how the condensate is isolated, it will be too large, and the minimum violation of the installation technology will lead to a variety of problems.
Coaxial chimney is excellent option For installation on the tipping pipes of combustion products on the gas boiler, as relative to other structures, it has a lot of positive sides and a long service life. The most important thing is to purchase high-quality equipment and correctly implement installation.

FEATURES OF MONTAGE
Anyone wants to be warm in his house. After all, it is precisely from this to the comfortable stay of the whole family. Those who have no centralized heating should take care of him. In addition to installing the boiler and other components, it is necessary to solve the chimney question. Without it, smoke from combustion of fuel would be straight into the room. Previously used ordinary pipes for this. However, coaxial chimney invented over time. What is this device? What is its advantage? These issues should pay special attention.

However, there is a problem with which you can still encounter - freezing of the chimney. If you ignore this opportunity, the frost can lead to a breakdown of the heating unit. At the moment, experts believe that the problem is in the wrong heat engineering. As kpd. heating apparatus It depends on how well heated air, the designers have reduced the pipe diameter to exit the combustion product. They have increased efficiency. However, precisely because of this, there is more condensate in the inner tube, which subsequently freezes. To avoid this problem, it is advised to correctly select the diameter and the length of the pipe.
