Many consumers who want to mount the heating system on their own often ask the question of how chimneys for boilers with their own hands are installed. We will try to answer them.
Which chimneys for gas boilers are better?

Today, gas boilers are widely used to heat various buildings. It can be multi -storey buildings, cottages, cottages. Such popularity is determined by the low price for gas boilers and fuel. However, in order for the system to work efficiently and efficiently, and all combustion products freely went out, it is important to arrange a chimney how to equip. You need to choose it correctly and competently mount it. Any errors during installation can turn into serious problems in the future and reduce the service life of the entire heating system.
A qualitatively installed chimney, provides an unhindered output of combustion products, good traction, supports clean air in the room. He must meet the basic safety standards and quality standards. The chimney should be fireproof, have a pleasant appearance, have good thermal insulation and easily install. Therefore, it is important to choose the right thing. Today, modern chimneys differ in form (cylindrical) and the material of manufacture is considered the best. The following pipes are most popular:
Brick;
steel;
Ceramic.
Brick pipes are not in special demand, as they differ in a short life. This is due to the fact that condensate is often formed on their walls. Stainless steel pipes have a much larger consumer period. Sandwich chimneys are especially popular. They are easily installed, quickly warmed up, have good traction and perfectly remove combustion products. Ceramic pipes also have good operational properties. But they are not so popular to a greater extent due to their high price.
In addition to pipes, all kinds of shaped elements can also be selected to the chimney, which provide proper configuration.

Before starting to mount chimneys for boilers with your own hands, it is important to know a number of mandatory requirements. In general, there are a lot of them, but we will list only the main. It is important to read the instructions and technical documentation for the boiler. See what requirements the manufacturer makes. Usually the necessary height of the chimney and the diameter of the pipe are prescribed there. A circle is considered the ideal shape of the cross -section (as the most convenient for installation). The diameter of the pipe should match the diameter of the pipe. A slight decrease is sometimes allowed (up to 5%). But then such a change is compensated by the length.
The height of the pipe can vary depending on the shape of the roof, as well as on where the chimney is located (from the wind -up or leeward side). The material from which the chimney is produced should have resistance to aggressive chemical components. During operation, it will often be cleaned with various means, so the material should not be destroyed. Gas boilers often require a tee of condensation. If it can not be used for fireplaces or stoves, then for boilers it is required.
What are the features of installing a chimney for a gas boiler?
The installation of the chimney directly depends on the number of parameters. To give specific instructions acting for all heating devices is impossible. So, the size of the chimney depends on the power of the gas boiler, the width of its output pipe. The height of the pipe is calculated depending on the shape of the roof and dimensions of the nearby buildings. All these parameters are collected, and a specific drawing is made, on which the assembly scheme for the entire structure as a whole is indicated. The specialist can best do this. But, if you wish, you can do it. It is only important to have technical documentation for the boiler under hand.
During the connection of the boiler to the chimney, there are often small inconsistencies in diameter. Therefore, you can use a special adapter. Subsequently, this zone is mandatory processed by a heat -resistant sealant. Next is the assembly of the chimney with a gradual expansion up. During the output of the pipe out, necessarily inserted a metal sleeve into the wall. The space between the wall and the sleeve is filled with sealant. The outer pipe is additionally coated with thermal insulation material and casing. A small hatch is created in the pipe rotation areas for cleaning the knee and washing condensate.
