Air-exhaust flue pipe DN80/125, white, push-fit 2000mm 2651469

Dual-function system for condensing boilers

This white pipe with dimensions DN80/125 and a length of 2000 mm is a ready-to-use coaxial system component designed for the safe evacuation of flue gases and the intake of fresh air from outside. The telescopic "push-fit" construction significantly simplifies the installation process – the installer does not need to perform additional cuts or apply complex gaskets, which speeds up work and eliminates the risk of leaks resulting from connection errors. For the end user, this ensures that the boiler will operate under optimal conditions, while the building façade remains aesthetically pleasing thanks to the uniform white finish of the pipes.

Practical application and operational benefits

The main advantage of this solution is its versatility in closed systems. One outer pipe (125 mm diameter) surrounds the inner flue pipe (80 mm), allowing two processes to be carried out simultaneously:

• Air intake: Fresh air is drawn through the space between the pipes directly into the combustion chamber, which is crucial for the efficiency of condensing boilers.
• Flue gas evacuation: Combustion products are safely directed outside the building through the central part of the pipe.

This design eliminates the need to drill two separate holes in the wall, which not only improves the appearance of the façade but also reduces the risk of damaging the building's thermal insulation. The white coating color ensures that the pipe blends subtly with most modern facades, not standing out as a technical element.

Installation and resistance to external conditions

The push-fit system allows flexible adjustment of the section length to the needs of the installation – it is sufficient to insert the inner pipe into the outer one until the appropriate tightness and stability are achieved. This makes installation quick even in difficult terrain conditions or with limited working space. The material ensures resistance to chemical corrosion and high flue gas temperatures, translating into a long service life of the installation without the need for frequent inspections or repairs. This is a solution dedicated to gas boilers requiring a closed system, guaranteeing safety and compliance with the requirements for next-generation heating appliances.
