With all the advantages of steel chimneys, they are also distinguished by high reliability and durability. Their elements consist of an inner fire clay pipe, an insulating layer on the basalt rock and the outer shell – lightweight foam concrete or stainless steel. Price refractory elements Flue slightly higher than that of steel. But everything pays off long-term operation. The modern market offers and more exotic materials for the chimney.
For example, glass. The advantages of glass flues are: they do not corrode, do not absorb moisture, have a low thermal inertia. But now such chimneys are very expensive and require costly installation. It is possible that in the future, the glass gradually replace other materials production of chimneys. I must say that we have to build more flues used asbestos cement pipes. Unfortunately, this comes from poverty. It should be borne in mind that they are perfect for this purpose not intended.
The fact that this material is carcinogenic to lightly cover the eyes that, as the most dangerous thing that the asbestos-cement pipe fire risks! You should not put their lives at risk for the sake of a dubious economy. Thus, modern chimney systems have significant advantages over traditional brick. And thanks to its characteristics and versatility in a leading position in the now emerging steel flues are made of stainless steel. Its advantages over Steel 3 ("black" steel) are obvious. Low corrosion resistance of the material leads to complete destruction of the air holes in a fairly short time. His primary cheapness leads subsequently to a permanent additional investments. And a decent portion of these costs falls on reassembling the chimney. The more so because the smoke channel is made of stainless steel, reliable and therefore, significantly increases the fire the whole heating system. Single-flue There are two types of metal chimneys – single circuit and double-circuit.
