Listing controls
A concentric flue with a diameter of 80/125 mm carries both the air intake and the flue gas exhaust in a single pipe – it is used especially with higher-output boilers or with longer exhaust runs, where the smaller 60/100 mm diameter is no longer sufficient.
In our range you will find chimney caps, separate exhaust connectors, vertical exhausts with air supply, T-pieces with an inspection opening, coaxial elbows and extensions of various lengths.
Frequently Asked Questions
- When do I need the 80/125 mm diameter instead of 60/100 mm? For higher boiler output or a longer flue run (more meters/elbows), the manufacturer usually specifies the larger 80/125 mm diameter – you can find the exact value in the boiler's manual.
- Can 80/125 mm components be combined with 60/100 mm? Not directly, these are different diameters – a special reducing adapter is needed to switch between diameters.
- What is a separate exhaust connector? With some boilers, it allows switching from a concentric connection on the boiler to a separate (independent) routing of intake and exhaust.
