Criteria for selecting steel chimneys for condensing boilers

When choosing a steel chimney, several key factors should be considered. First of all, the power of the condensing boiler is important. It affects the required diameter of the chimney pipes. The length of the planned installation is also important. It is important when selecting the appropriate system elements.

Another aspect is the method of running the installation. Different solutions are used when draining through the wall. Others when draining through the roof.   It is also important to take into account local building regulations and standards.   They influence the selection of specific elements of the chimney system.

1. Condensing boiler power
2. Length and route of the chimney installation
3. Method of exhaust gas discharge (through wall or roof)
4. Compliance with local regulations

In our daily practice, we encounter various challenges. We recently completed a project for a large housing estate. It required the use of a chimney system for 50 condensing boilers. Selecting the right pipe diameters turned out to be crucial. We had to take into account the different power of the boilers in the individual apartments.

Another interesting case was the modernization of the heating system in a historic tenement house. Here, the challenge was to route the installation in the existing chimney flues. We used special sets for the shafts. This allowed for the effective use of the existing infrastructure.
