Compliance with all necessary technical requirements in the design and installation of the chimney is one of the most important conditions for creating comfortable conditions in a private house.
If the smoke evacuation system is improperly installed, the risk of smoke and the creation of conditions for reverse thrust becomes very high. So, in case of violation of the rules for the construction of this most important system, fire hazardous conditions are created. Consequently, living in a house, in which the chimney was built in violation of the rules, becomes very dangerous.
Chimney device in the house: requirements that must be met to ensure safety
To comply with the standards that ensure the high-quality performance of work on the construction and arrangement of the chimney, it is necessary to:
- to construct a chimney made of non-combustible material (the recommended level of fire resistance must be at least 1 h),
- ensure reliable chimney tightness,
- to carry out all the installation of the chimney so that the combustion products do not fall inside the building,
- position the chimney canal vertically,
- calculate the exhaust hole in accordance with the boiler chimney area.
When removing the chimney pipe, it is necessary to follow the recommendations of specialists when determining the required height of the chimney pipe in accordance with its location, the allowable distance to the ridge of the roof (with a pitched roof):
Efficient chimney function - strong thrust needed
Choice of chimney design options: the need for traction and the ability to retain heated air indoors
At installation of a flue in the private house 2 main designs will be applied. One of them is a plastic stocking that heats up quickly and creates strong traction. In addition, this design is rapidly cooled, so that hot air after cooling a source of heating, for example, a fireplace, leaves smoke channel can not.
Another option is to use a three-layer construction - a stainless steel pipe covered from the inside with a ceramic layer, thermal insulation (usually mineral wool) and steel pipe outside - ensures the reliability and high efficiency of the smoke removal system. When constructing log houses, as a rule, this type of chimney structure is used. In addition to compliance technical requirements Such a smoke exhaust system is relatively inexpensive, which ensures its widespread use.
How to make a chimney in a house outside?
When constructing an external chimney in the house, the installation is carried out from the bottom up. The easiest way to purchase a finished chimney. In this case, the time of work can be reduced. In addition, the guarantee of a beautiful appearance designs. The chimney links are collected sequentially. To protect the chimney from moisture, all joints should be treated with a sealant. The structure is fixed to the elements of the building with the help of brackets.
For solid fuel boilers, bricks are often used. Such a chimney is quite heavy. Therefore, it is recommended to place the chimney of such material on a solid foundation or reinforced concrete floor.
When constructing chimneys for modern boilers for which liquid fuel and gas are used, the brick chimney is not suitable, as the brickwork starts to collapse very quickly due to the humidification of the pipes. Experts recommend the construction of chimneys made of ceramic pipes for such boilers. Such chimneys are universal and suitable for boilers operating on any type of fuel.

A chimney or chimney is part of a complex mechanism for removing smoke and gases from the heating system. All heating appliances that run on dry, gaseous or liquid fuels must have such a system in order to meet all the rules and regulations.
The chimneys in the house are designed for removal of combustion products due to natural thrust this design. The service life of the boiler and its ergonomics are directly dependent on the proper removal of such products of combustion. Therefore, the question of the device chimney in a private house and the choice of a suitable model remains a priority for each client.
The conditions of use of the chimney in a private house affect the characteristics of its design and the choice of material from which it needs to be made. That in turn will affect the performance and quality of any heating device.
If you raise the issue of the trend of growth of houses in summer cottages and near megacities, then there is a significant increase, with it growing faster than the number of houses made of brick or other material. But first of all, to buy or build a wooden house, you need to learn the technique by which the chimney is made wooden house . A lot of useful will be just in this article.
The future owner of a cozy wooden cottage needs to get used to the idea: the number of stoves in the cottage corresponds to the number of chimneys, the number of areas that are ventilated is equal to the number of ventilation channels. The level of traction occurs when the temperature difference in the rooms and output products. Therefore, the chimney in a wooden house set higher than usual. Just do not confuse the chimney and flue - this is all different designs . Most of what comes up to the first one doesn’t fit the second one at all.
It is worth remembering that pipes for smoke are not always permissible, if there are no statutory charters, which are kept as a guide when building pipes. According to the norms chimney need to build exclusively at an angle of ninety degrees (from clay bricks, without projections). According to the documentation, the pipe should be deflected at an angle of thirty degrees from the vertical, moving in a horizontal position no more than a meter. The pipe for smoke is at least five meters in height, but the height of the chimney is calculated from the base of the grate.
A chimney in a private house is of particular importance. Today there are many installation options and chimney construction options. I would like to mention the option of a sandwich. It is a heat-insulated pipe, which consists of: metal pipe (stainless steel), external steel pipe, material for thermal insulation. Stainless steel pipe also contains a layer of ceramics. To preserve heat, use mineral wool. All parts are mounted with special locks and sealant. But the latest design of the chimney should be used with the participation of the outer wall.
The life of people depends on the device of a flue in the house. Therefore, the chimney device in a private house is made durable and durable, while the chimney must withstand temperature changes, promote quality gas removal, resist the effects of condensate, as well as acids formed during operation of the heating system.
Such types as: stainless steel chimneys and brick chimneys are widely used. Only recently appeared alternatives brick chimney in a wooden house, and before that all the structures were made of brick. True, today such a pleasure - a chimney device in a private brick house - not everyone can afford it. But do not exclude such a laying, if it fits perfectly into the design of a cottage or any country house. But there is a good alternative.
A stainless steel chimney may even be more expensive than a brick, but it has a large number of advantages when compared. The latter option is much easier than the first one - from brick. So the construction of the foundation (reinforced) under the chimney is not necessary. It is simple in its installation and is stable in various factors of furnace gases (both thermal and chemical corrosion). The advantage is the durability of such a chimney and the ease of installation of the chimney in a wooden house.
Pipes chimney (stainless steel) - important element chimney, which is made of durable (relatively hot) stainless steel, while its design is made according to the principle - a pipe in a pipe. The gap between the pipes is filled with fire resistant insulation. therefore inner tube protected from condensation, and soot is not delayed. Manufacturers of such chimneys give a good guarantee - up to ten years of service without any interruption, although brick versions of chimneys can work even longer.
In each private house there is a smoke exhaust system. In addition to its primary function of smoke exhaust, it is also used as ventilation. Many people mistakenly think that it does not play a significant role in their life, and forget to take care of it, or they initially violate some of its installation rules. In order to understand what the negligent attitude of the consumer can lead to, we will deal with what a chimney device is.
How does it work
The flue system of a private house is a special channel for the discharge of gases and combustion products to the street. Improper planning of such a system can lead to the fact that the smoke will get into the rooms of the house or there will be problems with the back pull. The installation of the chimney, namely its size and location, must be very precisely calculated, otherwise a fire may even occur in the house. Of course, the channel walls are very hot during intensive work, which alternates with its complete cooling. Such a temperature difference is not at all beneficial to the working surfaces, but contributes to their rapid wear. That is why the installation of the chimney should include laying bricks. Brick walls around the canal provide it with a long service life, due to the fact that the brick balances the temperature difference, taking part of the heat itself. Thus, the heat in your home is stored longer with less wood and coal.
Modern designs and technologies offer a wide selection of equipment and the chimney itself. Among them are double-circuit, coaxial and others. The most effective are coaxial stainless steel devices. They have a dense layer of insulation, due to which the walls of the channel are protected from acid exposure. It is important that their interior is made of polymeric materials.
A chimney in a private house definitely needs proper operation by its owners. It is necessary to take into account that the temperature of the smoke rising through the channel can reach 600 degrees. Therefore, to install the chimney was literate, Brick wall must be quite thick, able to withstand exposure high temperatures . For this usually use 12 centimeters brickwork or ceramics. Steel is also suitable for this purpose. Channels from steel are very convenient in use and installation. Their design contributes to the rapid removal of hazardous condensates from the chimney, and also prevents friction of gases on its walls. A stainless steel chimney device has several advantages over others:
- suitable for any boilers and stoves;
- you can not worry about the occurrence of corrosion, as stainless steel is not afraid of it;
- You can install both at the time of construction, and in the already finished house.
On the market today there is a huge amount of quality equipment for chimney devices. The most popular brands are “FF Bofill”, “Selkirk”, “Raab” and “Hild”. No matter how high-quality and expensive your chimney is, it does not at all exempt you from caring for it. Pipes need to be systematically cleaned from soot and soot. A device of the chimney and its walls need to be checked. Even the smallest crack can spoil it. If at least some moisture gets there, it will lead to its destruction. So take care of quality air supply to your home, first of all you should do it yourself.
As we have found out, most modern devices installing is pretty simple, but there are several important moments , which you need to know before you start installing the chimney. It is necessary to carefully check the section of the wall through which the pipe will pass. Ideally, no joints should be observed there, and it should also be isolated from the wall. As a special measure when installing a chimney in a wooden house, it is important to isolate it from wooden walls non-combustible materials. Perfect brick or asbestos.
You can install the chimney in a private house by yourself, taking into account the following recommendations:
- It is necessary to remove the horizontal part of the pipe from the boiler.
- Fix the tee or the knee on the outer edge of this pipe to fix its vertical segment.
- If you use a tee, then it is important to take care of blocking its bottom output. In the case of the knee, it is necessary to ensure the possibility of cleaning the horizontal section.
- It is necessary to attach the vertical part to the wall with the help of special brackets, which are located at a distance of two meters between them.
- If the vertical pipe is made of heavy materials, then it must be supported with a support.
- The distance between the edge of the roof and the edge of the chimney should be no less than half a meter.
- Of course, it is better if the flue duct is attached to the wall along its entire length, but in many cases this is not possible. Then you should use the system of stretch marks.
All connections are tightly fastened to each other and sealed with hose clamps. Vertical pipe must provide high-quality insulation, for this they use mineral wool and other materials. Areas that may be subject to corrosive processes, you need to paint a heat-resistant paint.
After the installation of the chimney is completed, you can admire the work done, and become the owner of a high-quality chimney system.
