The most optimal choice for hot water in the house or apartment is called the gas column. But one of the conditions for mounting most of the models of such equipment is the need for chimney. Therefore, thinking about buying a column, the user should learn more about the rules of the chimney installation, as well as on possible alternatives to this type of branch of combustion products.

Chimneys for gas heaters are classified depending on the material from which they are made. Allocate:
- Corrugated flexible air ducts. There is a wire spiral inside such pipes, and the pipe itself is made of aluminum foil. A plus of this chimney is the possibility of bending at any angle and changes in length using metal scotch.
- Aluminum exhaust pipes. Their advantages are low weight, availability, lack of condensate formation inside the chimney. However, in winter, without insulation, such pipes may find out.
- Galvanized chimneys. They have low weight and quite high resistance to corrosion. Steel chimney is also important to warm in the cold season.
- Sandwich chimneys. Their design is one pipe located inside the second, and there is a non-combustible insulation between their walls (often mineral wool) for preventing condensate formation. Such chimney is called durable and reliable. It is often recommended for mounting in a private house when the chimney pipe must be carried out through the roof and overlaps (especially if they are made of combustible materials).

Coaxial Chimney for Gas Column
This is a modern and quite popular version of the chimney, which is used for turbocharged columns, characterized by the presence of a closed combustion chamber. Its design is represented by the pipe in the pipe, while the smoke is derived from the column, and fresh air from the street comes into the gap between the outer and the inner tube to the combustion chamber of the device.

Such a design allows you to make an exhaust pipe of a smaller length and increase the efficiency of the device. In addition, the column with this variant of the chimney will not exist oxygen in the air of the room, which is usually occurs when the combustion chamber is open. Stopping the choice on the turbocharged column, it is not necessary to take care of sufficient ventilation of the room, however it is important to pay attention to the choice of the chimney diameter. It is necessary that its diameter is not less than the outlet of the column.
What diameter of the chimney should be?
The selection of diameter is carried out with regard to the performance of the column, that is, based on its power. For almost all the heaters used in everyday life, the pipe diameter 11 or 13 cm is needed. At the same time, for devices with a capacity of up to 20 kW, providing water with one point, usually choose a pipe with a diameter of 110 mm, and for a high capacity column, more than 21 kW, from which water Twisting 2-3 cranes, the pipes of diameter of 130 mm are required.
Features for installation in the apartment
To connect a standard gas column in an urban apartment, a stationary canal must be present in the house. In most modern buildings, such ventilation channels are laid in the walls, so the chimney from the column is not a problem. However, in many buildings of the last century there are no such channels, so the usual column cannot be installed in them. In this case, you can stop the choice on the turbocharged model.
Other singing features of the chimney in apartments are such nuances:
- Chimney inside should be smooth and without any narrowings.
- Most often it is installed vertically. Not more than 3 bends are allowed.
- The pipe should be well sealed to avoid hitting the combustion products into residential premises.
As for the choice of pipe material, the corrugated aluminum, despite its simplicity and low cost, is called an inappropriate option. Such pipes are quite quickly roasted, therefore it is recommended only with rarely using the column. To install in the apartment, the chimney of steel is more preferable.
Features for installation in a private house
If the chimney was thinking at the construction stage of the building, the best choice would be the arrangement of a vertical brick mine, inside which steel or asbestos pipe can be located. At the same time, it is important that the gas column and the heating system have different mines for removal of smoke.

If the building is already built, the most appropriate variant of the chimney is a warmed steel pipe. It can be attached to one of the outer walls, and establish inside the building through its overlap and roof.
Other nuances of the chimney plant in the house are the following points:
- The material and design of the chimney, as well as the installation site must comply with the current standards.
- To chimney, easy access must be provided, so that if necessary it was possible to quickly eliminate possible problems.
- By mounting the chimney in the house vertically, it is important to prevent a significant deviation of the pipe - it should not deviate over the entire design by more than 1 meter.
- The end of the chimney pipe should protrude above the roof at least 40-50 cm.
Installation steps
Installation of chimney when installing a gas column includes such actions:
- Assessment of conditions for installation work.
- Choosing a suitable variant of the chimney.
- Installation of the flue of the chimney at its connection with a gas column.
- Installation of the chimney pipe inside the house or on the outer wall (for installation in a private house).
- Removing the pipe through a hole to the street (if coaxial chimney is mounted).
- Check thrust.
When the chimney is not needed: smoothly speakers
Nowadays, it is such devices in connection with the spread of turbocharged columns, as they do not need a special chimney, and their coaxial chimney is excreted through the wall. However, there are also columns that derive combustion products to the premises in which they are installed. As a rule, these are low-capacity low-capacity models. An example of such a column is the nova 3001, the power of which is 9 kW, and the performance is only 2.6 liters per minute.
To install such a column, good ventilation of the room is very important, but even in this case there is a risk of carbon monoxide poisoning, because it does not smell and affects a person when he does not even suspect the deadly danger. That is why the smokeless column loses the turbochable and has been practically not used recently.
