Dear customers,
we understand that designing a flue gas exhaust can sometimes be complicated from your point of view, so there is the option to use a short guide and we will design the flue gas exhaust for you.

Or you can assemble the entire flue pipe yourself. All components are available for a separate exhaust with a diameter of 80mm. |
Frequently Asked Questions
- What diameter of flue pipe do I need? Common condensing boilers use a concentric exhaust of 60/100 mm or 80/125 mm, or a separate (classic) exhaust with a diameter of 80 mm – you will find the exact diameter in the manual for your specific boiler.
- What is the difference between a concentric and a classic flue pipe? A concentric flue pipe carries both the air intake and the flue gas exhaust in one pipe (pipe within a pipe), while a classic (separate) system handles the intake and exhaust with separate pipes – suitable especially where the intake needs to be taken from a different location than the exhaust.
- Can I assemble the flue pipe myself? Yes, we offer all components for both separate and concentric exhausts – if you are not sure about the design, we will gladly prepare it for you according to your boiler and layout.
- How far can the flue gas exhaust be routed from the boiler? The maximum length depends on the type of boiler and the diameter of the flue pipe (the manufacturer specifies the maximum number of meters and bends) – for longer runs we recommend consulting the design in advance.
