Currently, to solve a heating problem, manufacturers can offer a wide variety of options for gas boilers. Among them, one of the leading positions in demand is occupied by wall -mounted heating models that are offered on this site.
It is worth knowing that the installation of any wall gas equipment involves the presence of a chimney. Although it is also necessary to emphasize that, depending on the type of equipment selected, a chimney installation method also varies. This method depends mainly on the principle of removal of combustion elements.
This principle is carried out by a couple of ways: by natural or by forced traction. In accordance with this, wall -mounted boilers have an open or closed furnace chamber.
The difference between chimneys for wall boilers
Wall models that have a closed camera work, in principle, due to forced traction. The fan mounted inside such equipment allows better removal of combustion elements, while the need for air tributaries from the room is canceled, and oxygen is not burned.
For this type of gas boiler, it is necessary to install a special coaxial chimney. This is easy and cheap. The coaxial chimney is plastic pipes that are inserted one into another, with a small diameter – up to twelve centimeters. They go outside through the required hole in the surface of the wall next to the boiler.
In the second version, boilers that have an open camera require a very expensive and insulated chimney established according to the rules.
