The chimney, also known as the chimney, has a wide range of materials and variations of its installation. Most of the choice is left to the owner and his personal preferences regarding certain characteristics. But consider everything in order.
Views
The chimney, in addition to the division according to the materials of manufacture, may also differ in its installation specifics.
There are the following types of pipe installation:
- External chimney.
- Indigenous.
- Hidden.
- Nozzle.
When choosing a material for a chimney, it is also important to consider that depending on it, the approach to laying the chimney may change. So, when installing a cast-iron and steel product, the laying process will be very different from brick and occur in different ways.
What determines the choice of material?
When choosing a material, you need to remember that stove heating can be removed from the house in two ways:
- Through the wall.
- Through the attic and the roof of the building.
Depending on this, you must also choose the type of chimney used. Suitable for the first categoryexternal and hidden chimneys, while under the second - mounted and root.
Therefore, in the process of choosing products, you need to find out how the pipe will look, in which direction it will go. And only then proceed to the selection of material.
Material selection
The most common are brick, metal and sandwich chimneys. The undeniable advantage of metal pipes is their durability, which is why they are considered one of the most common materials. Brick pipes, on the other hand, are easy to install and use.
Sandwich chimneys have begun to gain popularity only recently. However, they are considered one of the most progressive materials in use. Quality and ease of installation captivate customers.
There are also other types of pipes. But they are not so simple and practical to use. For example, installing ceramic does not take much time, but requires certain skills.
Asbestos cement
Asbestos-cement pipes should be singled out as a separate category. According to their characteristics, they are not too different from metal ones, but they have a much lower cost.
Among the advantages of such structures are:
- Corrosion resistance.
- Resistant to aggressive environments.
- Durability.
- Slight hydraulic resistance.
- The ability to not change size with temperature changes.
Also, asbestos-cement pipes can be machined and do not freeze. Thus, this type of structure is great for chimneys, because it has a number of necessary characteristics and is not too expensive.
Material specifications
No matter what material you choose, you need to know that only materials that have the following characteristics are suitable for laying chimneys and chimneys:
- Resistant to high temperatures.
- Easy to assemble.
- Low cost (to facilitate the replacement of a certain amount of material if necessary).
At the same time, cleaning of chimneys should be easy and efficient. This work should be done at least once a year.
Roof structure
The chimney on the roof has its own installation features, which must be followed during installation. First of all, you should remember that before installing any type of pipe, you need to think as much as possible how it will fit into the interior and whether it will fit into it in principle.
When installing a chimney on the roof, you must also make sure that there are no communications above the installation site so that access to the roof can be easily provided.
You need to make sure that the foundation in this area is as strong as possible, which will avoid unnecessary trouble during the assembly process or directly in use.
The main factor when bringing the pipe to the roof is to ensure the evenness of the structure. Only in this way can maximum safety and the best traction be ensured. The pipe must not be moved to either side.
Insulation of this design can occur with the help of bas alt wool and a casing, which must be installed along the entire length of the pipe. This step is quite important if you plan to use pipes for space heating. If you do not take care of the insulation, this can lead to the fact that most of the fuel will be spent on heating it, and not on the room.
In this installation, the following factors must be taken into account:
- You need to install an additional box. And if the installation takes place without it, there should be a large gap between the pipe and combustible structures.
- The output structure must not have joints. If this condition is not possible, it is recommended to tighten the connecting places with iron clamps and do it above the roofing material.
- When laying brickwork, it is better to use fired brick, which can be installed with both cement and sticky clay.
- Easy to use ready-made chimneys that do not need additional tightening. It is enough to install such structures on the street - they are isolated and well protected. This technology has been gaining more and more popularity lately.
An important condition is the installation of a visor on the pipe. This step is not only attractive, but will also help protect the inhabitants of the house from getting sparks or precipitation into the premises. This makes the design safer.
Stainless steel constructionssteel
Stainless steel chimneys have several advantages over other materials:
- Can be used for stoves or fireplaces with any kind of fuel.
- Have a smooth surface that increases the natural draft of the air.
- Can be used for both indoor and outdoor chimney.
- Fireproof.
- Have high corrosion resistance.
- Easy to install.
- Easy to clean.
- Small in size and light in weight.
- Easy to fit into old pipes. You can thus modernize the old structures and give them a new, more modern look.
- Durable to use. They are guaranteed for at least ten years.
- Can be used close to walls or any other element of the house with optional equipment.
Brick structures
Brick chimneys also differ depending on the type of installation and the exit side of the chimney. In general, they do not have any special differences from any other designs, however, they have a number of their own features:
- The product can only be installed vertically.
- The height of the pipe must be at least five meters to create optimal traction.
- If the house has stove heating and a fireplace at the same time, you need to make two separate conclusions for them.
- If the structure of the house is flammable, the pipes must be separated from it with special sheets.
- To prevent snow drift, it is recommended to make sure that the heightpipes at least half a meter higher than the roof itself.
- A node must be mounted at the exit point of the structure to avoid excessive moisture entering the room.
Cleaning
Why are chimneys cleaned? There are many reasons for this, including:
- Improved traction. Poor draft can cause smoke to be drawn into the room, and the house itself will not heat up to the right temperatures.
- Safety when it comes to a fireplace. If soot accumulates in pipes, this worsens traction and many other indicators, which can subsequently lead to cracks in the structure. And then sparks will fly into the room. This could lead to potential fire and a massive fire in the building.
Thus, do not ignore this operation during the operation of chimneys. This is especially true for those rooms where wood heating is carried out. Unlike coal, this material leaves behind much more soot. A thick layer of soot forms inside the walls. Because of this, hot air cannot leave the structure, which adversely affects the operation of the boiler and prevents the normal combustion of products in it.
Summing up
As you can already understand, chimneys have many variations, and their choice can be made solely on the basis of the choice of characteristics and the most convenient properties.
In the selection process, it is also importanttake into account the purpose of the pipes and their exit to the surface. You need to think about how they will fit into the interior, and prevent the presence of communications over the path of their installation.
Pipe installation can be done in different ways. Some structures can be installed independently, while others must be installed exclusively by specialists due to the too complicated technique of their application.
It is also important to consider the factor of resistance to high temperatures. After all, if the material is not resistant to large temperature changes or even just high temperatures, this can lead to the fact that the structure will soon collapse and be unsafe to use.
The choice of material and pipe outlet must be treated as responsibly as possible. After all, later it will be difficult to adjust your choice, and the consequences in the case of low-quality material can overtake you after a fairly short period of time.
The question of the correct selection of chimneys depends solely on the owners, because only they can know what the chimney should look like in their house, what type of construction they will choose and what its output will be.
After choosing the right material, one should not forget about cleaning the pipes, which should be carried out regularly to prevent fire or smoke from entering the premises. This step should not be neglected, and cleaning should be done systematically - at least once every 12 months. Thus, you can protect the residents of the house from the unpleasant consequences of their own negligence.
