Our life is moving forward rapidly. Scientific and technological progress regularly supplies new technologies, techniques and materials at our disposal. This also applies to construction, where more and more technologies appear that are distinguished by environmental friendliness, efficiency and ease of use.
These recent developments in the field of construction have become a
coaxial chimney. Translated from Latin, this means coaxial. It is a pipe-in-pipe system (bypass). Oxygen is supplied through the outer pipe to the boiler, which is necessary for the combustion process. Combustion products exit through the inner pipe. Such a chimney is made of high-quality heat-resistant
stainless steel .
This type of chimney was developed as an alternative to the usual one, which takes up a lot of space, requires taking into account a large number of nuances to create good draft and is mainly suitable for solid fuel stoves and boilers. Coaxial chimneys can be used both for conventional stoves and boilers, as well as for liquid fuel boilers and floor and wall gas boilers.
There is one feature: for the system to work, the boiler must be equipped with a draft fan. If a turbo boiler is available, a coaxial chimney is ideal for it.
The need for the use of chimneys of this kind was caused by mass gasification and the provision of apartment heating. The advantages of using such chimneys are obvious. It is easy to install, you do not need to take it out of the roof visor to provide traction, but you can simply take it out through the wall. The performance is much higher than that of conventional chimneys, due to the fact that the intake air is heated in the chimney itself. There is no need to often clean the chimney, and this increases the usability and comfort level. Suitable for any type of fuel. It can be displayed both vertically and horizontally. Eliminates the possibility of smoke in the room.
In order to choose the coaxial chimney correctly, you must definitely check the tightness of the welds, and also ask the seller about the availability of a quality certificate.
How is a coaxial chimney installed ? Installation does not require special training and time-consuming operations. A hole is punched in the bearing wall of the house and chimney pipes are inserted into it. During installation, it is necessary to make sure that all connections are tight, especially the connection of the external chimney pipe and the boiler pipe, so that there is no intake of air from the room, the air flow came only from the street and warmed up during movement. The connection of the chimney parts is done using a bell system. For reliability, a gasket made of heat-resistant rubber is inserted. It is worth paying attention to the fact that the structure is not located near the windows of a residential building, this is not at all correct, since air will flow directly into the living quarters.
Using new technologies, we bring comfort to our lives and can protect ourselves from many problems. Coaxial chimney will increase the efficiency of any heating system.
