What should be a quality chimney
Optimal variant of a quality chimney experts call that which is a channel with good thermal insulation, insignificant a deposition of soot, as well as a reduced level of condensate. Such chimneys tend to have a long enough working life and are able to withstand significant loads without compromising the house, bath house, cottage and other structures.
A quality chimney must first be designed so that the main requirement is met – the thrust increases with the increase in the height of the pipe. Otherwise (if the thrust is insufficient) there is a smoke delay effect in the smoke sink and even its return to the room. It should be taken into account that the appearance of the pipe and the coincidence of the proportions of the chimney and the building in this situation are secondary. After all, the functionality and proper operation of the heating system are particularly important in this situation.
It is important to determine the location of the chim So, for example, if it is to be classified as internal, additional work must be carried out fitting the support, organization of the correct protection, etc. If the option is internal, insulate it optional. However, at the junction point you will have to make insulation, which will be at least 60 cm before the exit.
It is worth considering that if the pipe during the internal stacking of the chimney passes through the unheated part of the room, the pipes will have to be insulated. Otherwise, from a sharp drop in temperatures they burst.
The exterior chimney, which bears the name quality, is usually a cylinder. This form ensures the most efficient operation of the smoke sink. Also, pay attention to the simplest models without any artistic delights. This is due to the fact that various ornaments and other intricate shapes lead to a greater accumulation of soot on parts of the pipe. As a result, the chimney more often starts to work worse and it will have to be cleaned more often too. It is desirable that the height of the outside chimney be at least 5 meters.
At a quality chimney, the joints at which the pipe is connected shall be located below the interstorey lintels and remain open for visual inspection. In most cases, it is recommended to further treat these joints with special non-flammable materials in order to achieve greater safety.
From which materials are made chimneys
Very often one can observe a painting when a bath house, cottage or house have a brick chimney chimney pipe crumbling, covered with white plaque and which has other destruction.$ This suggests that the wrong material was chosen to build the chimney. Today experts recommend only two materials – stainless steel and Hungarian furanflex for construction of chimney pipes.
Furanflex is a material of high strength and fire resistance. It is a composite metal product (it is a plastic reinforced with high-strength fibers). Its plus is that it is resistant to condensate, has low thermal conductivity and is perfectly applied where pipes are heated to 200 degrees.
The stainless steel has an optimal tube section, which creates the correct and optimal thrust. Furthermore, it is not subject to abundant condensate formation. Such a material specialics are called airtight and easy to maintain. And if you comply with all installation rules and properly operate a furnace or fireplace or gas boiler, the stainless steel chimney will be as fire-safe as possible.
As for other materials, from which chimneys are traditionally made, experts say that they are now becoming irrelevant due to their unsuitable functional features . Asbestos cement pipes are used as often as possible. The main reason why builders choose them is low price. At the same time, they are heavy, do not differ in special tightness of joints, absorb condensate and, as a result, destruct faster. If such material is overheated, the pipes can burst or even explode.
The zinc and steel pipes that are so often used in the construction of bathhouses also have a number of their drawbacks. Their service life is considerably short – from 2 to 4 years. Then, due to increased condensate formation, pipes begin to quickly rust, thinn and fall into disrepair.
Another unsuccessful material for building smoke diversions is brick. And that’s despite the fact that it’s used quite often. Brick is bad in that it quickly collapses under the influence of condensate moisture, very intensively absorbs it into itself, as a result of which even walls are wet, the brick itself simply crumbles.
If you want your chimney to be brick, just face it. But be sure to comply with fire protection standards of installation.
Remember that the correct (quality) chimney must necessarily be the correct dimensions, which are prescribed in the construction standards. According to these rules, a good quality chimney must be tight, vertical and detached. Also, he shouldn’t have any ledges. The section of the channel must be maintained along the entire length of the pipe. Otherwise, there will be traction issues.
Choosing the right chimney should be conscious. Therefore, before buying, be sure to study all the characetritics of the copy offered to you, so that you do not regret your choice. Do not pursue a low price, because subsequent repairs and problems that the wrong chimney can cause will cost you many times more.
