Ventilation system C

Ventilation system C combines mechanical extraction of stale air with natural supply of fresh air through windows and vents. The system is widely used in renovation projects, where available space is often limited and a system D is not always feasible. A well-designed system ensures sufficient fresh air, without drafts or disruptive noise. Burgerhout supports installers and consultants with smart solutions and practical design tools, so that the system fits within the home and works effectively in practice.

Hybalans+

An air distribution system that ensures flexible and efficient air distribution within the ventilation system. Due to its modular construction, Hybalans+ is easy to adapt to the situation in the home and keeps the air pathway clear.

In practice, that means:

  • Modular and flexible design that moves with the design
  • Quick and easy to install, with fewer site operations
  • Suitable for new builds and renovations, also for varying installation spaces

EasyAir EPS & EPP insulated ducts

Lightweight ventilation ducts with a high insulation value. Due to their low weight and fixed shape, the ducts are pleasant to work with and easy to integrate into the air path.

In practice, that means:

  • Easy to handle, even in tight spaces
  • Suitable for modern and existing buildings, for new builds and renovations
  • Ideal for connecting ventilation systems, with a clear system structure

How does ventilation system C work?

With ventilation system C, fresh air enters the home via vents and windows. At the same time, stale air is mechanically extracted from rooms where moisture and odours occur, such as the kitchen, bathroom, and toilet.

This combination ensures a continuous airflow through the property and contributes to a healthier indoor climate.

As outdoor air is supplied directly, correct placement of grilles and diffusers is important. This prevents draughts and maintains comfort and noise levels.

A good ventilation system is essential for a healthy home.

Requirements for a healthy indoor climate

Insufficient ventilation can lead to complaints such as fatigue and headaches, but also to moisture problems and the accumulation of pollutants in the home. Good ventilation is therefore a basic condition for a healthy indoor climate.

The BBL (Environment of Buildings Decree) stipulates the minimum amount of fresh air that must be supplied and extracted per hour. For renovation projects, it is often advisable to base calculations on new-build requirements where possible. This ensures that the ventilation system is better aligned with current insights and the comfort level of modern homes.

When designing a ventilation system, it's not just about the ventilation rate. These factors are also crucial for proper operation:

  • De positie van ventielen
  • De functie van de ruimte
  • De luchtstromen door de woning

That's why Burgerhout advises installers to look beyond the minimum requirements. With our calculation software, you can easily create a reliable ventilation calculation per room, providing a solid basis for a system that works well in practice.

The main considerations for a comfortable ventilation system.

Comfortable ventilation: a challenge

With ventilation system C, the supply air is drawn directly from outside. In winter, this means cold air enters the home. In strong winds, this can lead to draughts at ventilation grilles and reduced comfort. Good design is therefore essential.

Key points to consider:

  • Sufficient ventilation grilles
  • Correct placement of valves
  • Sufficient ventilation capacity
  • Quiet airflows

For example, a system with insufficient capacity may drain moisture from the bathroom too slowly. And if too much air has to go through a duct, it can cause noise nuisance.

With Burgerhout software, you can easily calculate the correct capacity per room. Based on this, you can assemble the system, which can then be installed plug-and-play.

Which ones do I need?

Ventilation system C or D?

Ventilation system C is often used in renovations where space for additional ductwork is limited. The system is practical and effective, provided it is well designed and suited to the home.

Is there indeed enough space available? Then ventilation system D is often the better choice. This system offers more control over the airflows and increases comfort in the home.

Why?

  • Warmteterugwinning verwarmt de toevoerlucht met warmte uit de afgevoerde lucht
  • Minder energieverlies
  • Minder kans op tocht
  • Meer controle over luchtstromen

Ventilation system D ensures more comfort and is often the most sustainable solution when the situation allows.
