Flue for stacked construction

A safe flue gas extraction system is essential in apartment blocks. Whether it’s central heating boilers, stoves or fireplaces: a leak in the flue system can have serious consequences. That is why there is one important rule: if you replace the appliance, you must also check and assess the flue gas extraction system. But which solution is best suited to your project? Burgerhout offers complete flue gas discharge systems for multi-storey buildings. From individual flues to CLV and Half CLV systems: safe, reliable solutions for new builds, renovations and sustainability upgrades, with minimal disruption to residents.

CLV, half-CLV or individual

Which system do you choose?

The right solution depends on the number of storeys, the available duct space and the situation of the building.

Individual

The ideal choice for buildings of up to approximately 3 to 4 storeys. Each dwelling has its own flue gas discharge and air supply via the roof or the facade.

CLV system

For multi-storey buildings, a collective system is often the best solution. Thanks to the concentric pipe-in-pipe design, a CLV system offers a high level of safety. Any potential leakage is immediately caught in the air supply pipe.

Half CLV

When the available space in the shaft is limited, a Half CLV system offers a solution. The flue gases are extracted centrally via a single pipe to the roof, while each dwelling has its own air supply via the facade.

The standard for high-rise buildings

Collective Systems (CLV)

Would you like to connect several boilers to a single shared vertical pipe? If so, a concentric CLV system from Burgerhout is a tried-and-tested, safe solution.

Due to its compact concentric design, the system combines flue gas discharge and air supply in a single shaft. As a result, the system is space-saving, safe and widely applicable in renovation and new-build projects.

Advantages

  • Telescopic connections for quick installation without the need for additional sawing.
  • Suitable for virtually all standard central heating boilers.
  • Maximum safety thanks to the concentric design.
  • Compact design for efficient use of available shaft space.

During renovations, a CLV renovation solution helps to make optimal use of existing ducts. The system also offers the flexibility needed for transformation projects, such as the conversion of offices into apartments.

Clever solution for lack of space

Half CLV systems for stacked construction

Is there insufficient space for a fully concentric CLV system? Then a Half CLV system offers a practical alternative.

This system combines a central flue gas discharge to the roof with an individual air supply via the facade. As a result, the required shaft space is kept to a minimum, while you benefit from a safe and reliable solution for multi-storey buildings.

Burgerhout supplies Half CLV systems in a range of configurations, ensuring that a suitable solution is available for virtually any renovation or new-build project.

Benefits of a Semi-CLV System

  • Requires less shaft space than a full CLV system.
  • Ideal for renovation projects and existing buildings.
  • Safe central flue gas discharge.
  • Flexible in application in complex building situations.
Flexibility of up to four storeys

Individual flue gas discharge systems for multi-storey buildings

For apartment buildings of up to approximately four storeys, an individual flue gas exhaust system is often the most logical choice. Each dwelling has its own flue gas exhaust and air supply, which keeps installation, management and maintenance straightforward.

Burgerhout offers a wide range of systems for new builds, refurbishments and replacements. Thanks to the wide choice of materials and diameters, a suitable solution is available for virtually any structural situation. The systems are designed for quick installation and comply with the applicable safety and quality requirements.
