The chimney system is often seen as an accessory to the main heating installation. But the function of such an addition is difficult to overestimate, since not only the quality of heating and the reliability of equipment, but also the safety of people depend on the ability of the design to rid the room of combustion products in a timely manner. An effective solution for such needs is offered by Schiedel developers. The chimney of this brand is available on the market in a wide range. A suitable design will be selected by both a private homeowner and the head of a large enterprise to equip a workshop or work site.
General information about Schiedel chimneys
The formation of Schiedel's production facilities took place in the 1940s. Today we can say that the company initially focused specifically on the chimney manufacturing segment. This allowed the company to form its own technological base. In particular, one can note the variety of unique design solutions that the German-made Schiedel chimney is endowed with. Metal and ceramics have become the main materials for the manufacture of structures, while the insulation and ventilation systems of the passages have undergone an innovative revision. If in the middleof the last century, the company relied on optimizing the dimensional parameters of chimneys, sections and other technical aspects, but recently the emphasis is on environmental friendliness, heat-ventilation function and energy efficiency.
Chimney specifications
One of the key parameters for assessing the compatibility of a chimney with a specific heating unit and room conditions is the height of the structure. In the middle range (8-10 m) the main Schiedel models are presented. Chimneys higher than 10 m may require the use of additional sealants. The inner diameter varies on average from 120 to 250 mm. In turn, the outer diameter corresponds to these indicators, but with an increase of about 30 mm.
You should also take into account the coefficient of resistance to vapor diffusion, which in this case is at least 550. The resistance of the material to acids is about 0.07% in relation to the change in mass, and the thermal conductivity, which determines and energy-saving function, is on average equal to 1 W/mK. But this mainly concerns Schiedel ceramic constructions. A metal chimney, in turn, shows not so high performance in terms of thermal conductivity. On the other hand, galvanized alloy models benefit from strength and durability. Now it's worth taking a closer look at the features of ceramic and steel structures.
Ceramic chimneys
The design of such chimneys is formed by a three-part system,including stone shell, insulation board, as well as high quality ceramic pipe at the base. The surfaces of the structure are equipped with special ventilation channels, due to which the ventilation function is provided. The features of ceramic systems include versatility and the ability to remove moisture with excess heat without harming structural elements. One of the most popular developments in this range is the Schiedel Uni chimney, which has additional top protection. The roof structure eliminates the negative effects of precipitation on insulation materials and pipes. With regard to versatility, the unit can be integrated into various roofing "pies" due to its compact size. It does not matter the type of fuel on which the heating system operates. These can be both solid resources and liquids with gases.
Steel structure
Despite the functional advantages and practicality of ceramics, many owners of private houses still prefer the more familiar metal, which is associated with reliability and durability. However, German designers allow you to combine the advantages of two materials. In particular, ceramic chimneys of the Kerastar series are based on a light ceramic pipe, the shell of which is made of stainless steel. That is, the direct function of smoke removal is performed by ceramics, and protection is provided by high-strength metal with an anti-corrosion coating. The system can be used not only asadditions to traditional heating units powered by wood, coal, natural gas, etc. Technologists have provided the possibility of integration into new pellet boilers and condensing units.
Installation of chimneys
Installation can be done both indoors and in the attic. In the first case, it is necessary to provide an insulating protective coating, as well as observe indents from the building structures of 20 cm. When all the initial calculations have been made, you can proceed with the installation. The special joint compound is generously applied to the socket of the pipes, after which the clamping collar is loosened in the lower area. Next, the upper part of the pipe is installed. In parallel with the physical installation, the system is assembled by tightening it with a clamp using mounting grooves and fasteners. Also, the installation of chimneys provides for the addition of precipitation removal systems. Condensate and rainwater are discharged into the sewer through special liquid collectors.
Schiedel product reviews
The units of this brand are famous for their reliability and durability. The latest models also receive a lot of positive feedback in terms of performance, ease of maintenance and overall maintenance. The materials from which German Schiedel chimneys are made are distinguished not only by heat resistance and high insulating qualities, but also by ease of cleaning. There are also negative reviews, most of which are addressed to the high price of this product. For example, basic one-way structuresabout 6-7 m high cost an average of 50-60 thousand rubles.
Conclusion
The chimney system performs a difficult task, which is complicated by the technological requirements for its implementation in the roofing base. The master must provide during the design and power loads, and compliance with tightness, as well as ventilation functions. These and other conditions are provided for in Schiedel designs. The chimney is initially designed with the expectation of a minimum of additional operations during the installation process. The design, which includes a pipe and protective shells, is completely ready for use in combustion products removal systems. After purchase, you only need to perform fixing operations and properly protect the circuit with insulators.
