Flue gas extraction systems for ground-based dwellings

A flue gas extraction system must be suitable for the appliance, the property and the available space. Burgerhout offers complete systems that combine safety, ease of installation and reliability.

Flue gas discharge starts with a complete system

Ground-level dwellings usually use an individual flue gas discharge system. In this context, the appliance, the available space and the discharge route together determine which solution is suitable.

A flue gas discharge system consists of multiple components that must be matched to one another. Together, they form a single safe and reliable complete system.

These parts include:

Foot connection
Pipe run with bends and extensions
Fixing and bracing
Roof or gable penetration

These components influence each other. The choice of appliance and the available space determine the drainage route, the maximum length and the type of system. At the same time, the chosen system and the throughput impose requirements on assembly, bracing and maintenance.

That's why at Burgerhout you'll find a variety of smart, reliable flue gas exhaust systems for residential buildings that prioritise not only safety but also ease of installation.

Safety and points to consider

Why flue gas evacuation in residential homes requires extra attention

Flue gas discharge in ground-based homes requires extra attention because the installation is often located close to living spaces. A leak, incorrect connection, or faulty assembly can therefore have direct consequences for the safety of residents.

Typical points of attention for flue gas discharge in ground-based dwellings are:

Limited installation space around the appliance
Short drainage paths with little margin for error
Existing shafts or penetrations during renovation
Variation in roof pitches and facade situations
Combinations of old and new installation materials

Furthermore, correct fixing, appropriate bracket spacing, and adherence to installation instructions play an important role. Deviations from these increase the risk of leaks, combustion disturbances, and the incorrect activation of appliance safety devices.

That is why Burgerhout’s systems have been developed for use in refurbishment and replacement projects. With smart components, clear installation instructions and a wide range of products, Burgerhout offers a suitable solution for both the replacement and refurbishment of existing installations.

Concentric, parallel, or flexible flues?

The correct choice of flue system for ground-level homes

When it comes to flue gas ventilation in residential buildings, a distinction is made between parallel (single-walled) and concentric (pipe-in-pipe) systems. Both can function safely, provided they are applied and installed correctly. However, in practice, there are clear differences.

Concentric (tube-in-tube)

A concentric flue system combines flue gas extraction and air supply in a single pipe-in-pipe construction. The inner pipe exhausts flue gases, while the outer pipe provides the supply of combustion air.

When would you choose this?
Concentric systems are widely used in new-build and renovation projects where safety, ease of installation and a compact design are important.

Advantages

Extra safety thanks to the tube-in-tube construction
Compact system requiring less installation space
Fewer brackets and components needed
Quick and clear assembly
A popular solution for ground-level homes

Parallel (single-walled)

In a parallel system, the flue gas exhaust and air supply run via two separate pipes between the central heating boiler and the roof or wall terminal.

When would you choose this?
A parallel system offers a solution when the available space, structural conditions or drainage route require extra flexibility.

Advantages

A great deal of design freedom in complex situations
Can be flexibly installed around obstacles and existing structures
Suitable for a variety of drainage routes
Widely applicable in renovation projects

Point of attention

For safe operation, correct installation in accordance with the applicable regulations is essential.

Flexible systems

Flexible flue gas discharge systems consist of pliable pipes made of plastic or stainless steel. They have been specially developed for renovation projects that make use of existing shafts, ducts or flues.

When would you choose this?
Flexible systems are ideal when a new flue gas discharge needs to be installed in an existing duct or a hard-to-reach situation.

Advantages

Ideal for renovation and replacement
Easy to install in existing shafts
Long lengths ensure quick installation
Optimal flow thanks to the smooth inner wall
Suitable for both detached houses and multi-storey buildings
