More and more people decide to replace their old coal boiler with a modern gas boiler. Thanks to it, you can save a lot. Of course, you also need to consider which chimney to choose for your gas furnace. Today we will present you the rules for selecting chimneys for gas boilers.

How to choose a chimney for a gas boiler?
The chimney is undoubtedly an important element of the entire heating system. Therefore, it must be selected appropriately, because it is through it that exhaust gases escape. The chimney parameters should be selected according to the power of the installed boiler. Moreover, in the case of gas boilers, extremely strong and durable materials must be used. Steel, which is resistant to mechanical damage, will work best here. In addition, steel chimneys for gas boilers are characterized by high tightness. It is also worth noting that they can even be used to renovate old brick chimneys. The installation itself is not expensive. So if you are faced with choosing a chimney system, a model made of steel will actually work very well. The steel chimney is also resistant to the harmful effects of condensate. Its surface is smooth, which prevents dirt from settling.
Or maybe plastic chimneys for gas boilers?
Steel chimneys are not the only solution that deserves attention. You can also choose plastic chimneys for gas boilers . They are made of plastic. Contrary to appearances, such models are also safe. They are particularly suitable for boilers with a closed combustion chamber, including condensing gas boilers. It is worth noting that such chimneys have high fire resistance. The materials used for production, of course, must be durable. Chimney elements made of polypropylene work very well and work effectively even at high temperatures, usually up to 120 degrees Celsius. Polypropylene is also a relatively cheap material and does not degrade quickly, so it can be used for many years. It is resistant to UV radiation. Additionally, such chimneys ensure good gas tightness. Chimney systems made of PPS work well even in overpressure or wet mode. The exhaust gas discharge system consists of an inner pipe and an outer pipe. Such a system can be used as a chimney liner in combination with single-wall systems or as a stand-alone system.
How to choose a chimney system for a condensing gas boiler?
Condensing gas furnaces allow you to recover additional heat that would be dissipated through the chimney in the case of a regular furnace. However, you must remember to select the appropriate chimney system. Here you should pay attention to:
- tightness and possibility of wet operation (The discharged exhaust gases are wet and
directed to the chimney under pressure. For this reason, the chimney system must be as tight as possible). - existing standards and approvals (All chimney systems must meet the most restrictive standards and approvals).
- cross-section of the insert (We distinguish round, rectangular or oval. If the chimney is square, a round insert can be placed in it, but if the chimney is rectangular, an oval or rectangular insert will work better).
- chimney height (Each boiler has a specific chimney height. It must be respected, otherwise the flue gases will escape incorrectly. In the case of condensing boilers, inserts with a diameter of 60/100 are most often used).
- the material the chimney is made of (we distinguish steel or plastic).

Noteworthy is the ONNLINE DN 80, L=250 chimney pipe with a condensing exhaust gasket for turbo and condensing boilers . It is made of strong heat-resistant and acid-resistant steel. It is designed for continuous operation even at 600 degrees Celsius. It is worth paying attention to the socket connection, which facilitates installation. The pipe is resistant to soot fire and is designed for a closed combustion chamber.
You can also choose a product such as the L-250 DN60 single-wall condensing chimney pipe with a gasket for Krzys-Pol condensing/turbo boilers . It is also extremely durable and resistant to mechanical damage. It is acid and fire resistant. The favorable price is also worth mentioning.
If you are looking for a plastic chimney, a straight PP L1000mm DN80mm chimney pipe resistant to UV radiation with an [EPDM] ONNLINE gasket may be the right choice. Quickly and effectively removes exhaust gases from condensing boilers. It has a system that works in overpressure and in wet mode, but remember that the maximum operating temperature cannot exceed 120 degrees.
