Chimneys made of steel pipes can be made quite easily with their own hands, you do not need to be professionals( like laying a brick chimney pipe), it is enough to study the necessary information and follow a clear plan of action.
But still you have to be extremely careful and cautious.
After all, if you do the work incorrectly, at best you will have smoke, and at worst, you can cause a fire.
Modern chimneys are rather complex systems that need careful selection and quality assembly work.
The performance of the whole structure is affected by the main factors:
- boiler efficiency level;
- fuel consumption;
- economy;
- security;
- the oven itself.
A chimney for a private house or a sauna is extremely important.
It does not matter what kind of unit you have - a gas boiler or a stove, you have a brick or a house made of wood, you can not do without a chimney anyway.
Correctly delivered chimney of quality materials should have the following properties: good draft, sufficient tightness( due to which no leakage of even a minimum amount of carbon monoxide is allowed), absence of soot and soot formations.
All these qualities are available in stainless steel chimneys.

Advantages steel chimney
Chimneys stainless steel have indisputable advantages:
- smooth surface inside the tube, which prevents soot deposits and soot(which can not boast a smoke exhaust system made of bricks);
- possibility of their installation in a dwelling or in a steam room of a bath;
- no need for a foundation;
- the ability to perform any repair work, regardless of the time of year;
- with a small amount of condensate, provided that it is properly installed and insulated( in the first place this applies to a chimney installed on a sauna stove);
- high resistance to negative effects of gas leaving the furnace or boiler;
- good strength;
- long life;
- the budget price( steel is much cheaper than brick);
- complete list of matches for fire safety requirements.
All these advantages made the chimney device of steel extremely popular.
In addition, if you compare a steel chimney with other chimneys( for example, with a brick pipe), then installing a steel chimney is much easier.
Compared with ceramic, the stovepipe from stainless steel has a much more reasonable price( if you do all the work yourself, the difference in price will become even more tangible).
Therefore, let's not waste money again and install the chimney installation ourselves. First you need to choose the right chimney system.
The video below shows the appearance of steel chimney systems.

Types of chimneys
To date, manufacturers are producing steel chimneys of 3 types.
Single-wall chimney is installed in an existing and installed chimney of brick or ceramic( it is used in the event that the installed system is not working properly, and there is no possibility to replace it or repair it).
Such a homemade chimney is fairly simple to install with your own hands, while the lower part of the system near the furnace must necessarily have a special device for collecting the released condensate.
The two-walled is made of a pair of pipes, and the cavity between them is filled with a fire-resistant insulation that has a low coefficient of thermal conductivity.
For installation by own hands basically it is chosen a two-walled version of the pipe system.
Thermal insulation for it is carried out with the help of a basalt insulation, which under the influence of high temperature does not melt and gives off an unpleasant smell.
The thickness of the layer of insulation is calculated depending on the climate and the location of the chimney, as a rule, it starts from 3 cm and ends at 10 cm( thick insulation is also used for baths to minimize heat consumption).
Coaxial chimney is made of two pipes as well as double-walled, but in this case the pipes are inserted one into the other. The pipes have different diameters.
The gas that is located inside( with a smaller diameter) is supplied with combustion gas, and its lifting is carried out with a special fan built into the boiler of the house or a sauna stove.
Through the gap between the inner and outer pipe, the supply of clean air is carried out, which is necessary for combustion.
Coaxial chimney is mainly installed for a sauna oven, as it better retains heat.
This system is more complicated than a double-walled one, but you can do it yourself if you want.
Installing the chimney
Which of the three systems of steel pipes will be installed on your boiler or sauna oven? Only you can choose.
In any case, the installation of a stainless steel chimney must be done taking into account the mandatory requirements( especially if you plan to do all the work yourself):
- collect the links of the pipe, starting from the bottom and slowly rising upwards, the upper segments must be as tight as possible in the bottom(existing joints can be sealed with a special fire-resistant sealant that can withstand up to 1000 degrees of heat);
- we insulate the chimney layer of insulation;
- if the roof of the house or bath is made of combustible materials, then we install a spark detector.
It is not difficult to perform these actions, it is much more difficult to lead a chimney through a wall or a roof to the outside of a house or a bath.
Flue outlet outside
The flue gas system is led either to the wall or to the roof, there can be no other options.
If the system passes through one of the walls, then the diameter of the cut-out hole should slightly exceed the diameter of the pipe, and not cut one to one.
This moment is necessary for the installation of a steel sleeve, which will protect the wall from heating and destruction under the influence of high temperatures.
If the pipe passing through the wall is quite long, then it is better to fix it using brackets.
It is also necessary to fasten the brackets to the pipe and on the outside of the house, so that it does not swing under strong wind and bad weather.
If you plan to remove the chimney through the roof, you need to take care of the protection of the overheating overlaps( the first meters of steel coming from the boiler are heated very much, and if from the sauna stove this heating occurs periodically, then from the stove or boiler in the house,heating in winter is almost continuous).
For this, it is necessary to cut a hole in a large diameter overlap and protect the material by applying galvanized steel with a layer of insulation.
Galvanized sheets will reflect heat well, and a layer of insulation will create a necessary layer that will protect the floors from overheating( this is especially true for a bath, where all the ceilings are made of wood).
Pivoting and tilting of the
pipe system If you do all the work on installing a steel flue using your own hands, special attention should be given to the pipe turns and the angle of their tilt.
On how you fulfill these conditions, the permeability of smoke through the pipe system and the heat preservation in the room will depend.
But do not be afraid ahead of time, the installation of steel pipes with turns easier to lay the chimney of brick.
If the steel pipe has one turn or even several, it is possible to connect its parts at different angles. The most common are 3 cutting angles:
- cutting a straight pipe at an angle of 75 degrees - allows you to form an angle of 150 degrees( for this, the cut pipe parts must be flipped and reconnected diagonally);
- when cutting a pipe at a slope of 60 degrees, you can form a rotation equal to 120 degrees;The
- cut, made at an inclination of 45 degrees, allows you to create a right angle of rotation.
The device of slopes is also of great importance.
For example, if the steel pipe going from the furnace to the wall will be located at a slight slope, this will not allow the creation of the traction necessary for the output of the smoke.
Subsequently, this will lead to the fact that all the smoke will not go out to the chimney, but into the room until the pipe properly warms up.
As you can see, the work is quite simple and you can do it yourself.
But if you have such an opportunity, it is better to seek professional help, because one mistake a beginner can cause a fire in a dwelling house or a bath.

Cleaning should be done regularly.
A straight steel pipe can easily be cleaned by hand with a brush( steel does not soot adheres to the surface like a brick), and if it has corners and turns, you need to take a flexible thick cable for cleaning.
