A properly selected and installed ventilation system protects the apartment and its users against harmful substances in the air. Their excess negatively affects human health and well-being, causing, among others, headaches, respiratory diseases and fatigue, and even increases allergies. Moreover, the high water vapor content results in constant moisture in the interior, which translates into the development of fungi on the walls. Therefore, every installer should recommend effective ventilation solutions to their clients!

Room ventilation - how do ventilation systems work?
The main task of ventilation is to exchange air in rooms. The system ensures the inflow of fresh air and removal of used air. This guarantees an optimal microclimate, which has a positive impact on the well-being of the building's users.
Proper ventilation should have adjustable efficiency, i.e. the ability to increase and decrease air exchange according to demand. The effective system prevents the growth of mold in rooms and protects them against damage caused by moisture. High-quality ventilation does not cause drafts and reduces the building's demand for thermal energy.
All harmful chemical compounds and unpleasant odors are removed from ventilated rooms, including water vapor, carbon dioxide, tobacco smoke and all by-products of everyday use of the building.
The exact mechanism of ventilation depends only on its specific type. You can read about the solutions available on the market below.

Ventilation systems available on the market
Investors can choose from many different types of ventilation. Each of them has slightly different properties that work well in specific conditions. The selection of a ventilation system for a building should always take into account its purpose, specificity and external environment. Let's take a look at the most important solutions available on the market one by one.
Gravity ventilation
This system is based on natural air movements, so it is strongly dependent on the difference between the external and internal temperature. The higher it is, the more effective the ventilation is. This means that the installation will be most effective in winter and least effective in summer. Its efficiency is also influenced by the wind force and the height of the ventilation ducts (the higher the better).
As you can easily guess, gravity ventilation is characterized by an unstable air exchange process. On the other hand, it involves low operating costs because the system does not require electricity to operate. It works well in rooms with fireplaces or boilers with an open combustion chamber. It is worth using it where the weather conditions are relatively constant and favor air flow.

Mechanical ventilation
In mechanical ventilation, air movement is forced by a device powered by electricity. The system consists of a duct fan, ducts and exhaust grilles located in strategic rooms (e.g. kitchen or bathroom). There is an air discharge outside the building.
The undoubted advantage of mechanical ventilation is stable operation and 100% efficiency. The intensity of the system is adjusted by changing the fan speed. However, the disadvantages include the costs of electricity and the unsuitability of ventilation for use in rooms where devices with an open combustion chamber operate (risk of backflow of exhaust gases).
Hybrid ventilation
The hybrid system combines the properties of natural and mechanical ventilation. It can operate in one or the other mode, and this is determined by external conditions. This is an interesting solution that allows you to save on electricity and ensures the operation of the system even in the event of a power failure. If atmospheric conditions favor the operation of gravity ventilation, mechanical devices are not used. However, if the conditions do not allow for natural air flow, the exhaust mode is activated.
Ventilation with heat recovery
It is also worth mentioning recuperation, i.e. supply and exhaust ventilation with heat recovery. Its key element is the central unit, where the channels that pump fresh air in and blow it out meet. Recuperation involves heating a stream of fresh air by used air. This obviously reduces the costs of heating the building.

Modern room ventilation with the OnFloor flat system
There are also innovative solutions available on the market in the form of air distribution systems, such as OnFloor by Zehnder. In this case, the intensity of the exchange is regulated depending on the needs, and the easy installation of ventilation does not interfere with the structure of the building. In this system, fresh air flows through oval ducts with a smooth internal coating, installed on a concrete base in an insulating layer.
The manufacturer's product range also includes InFloor ventilation systems, which work in the same way, with round channels placed in the concrete substrate. Both solutions translate into a comfortable, healthy and energy-efficient climate inside the building.
Advantages of the Zehnder OnFloor system
The OnFloor system from Zehnder has numerous benefits that make using ventilation exceptionally comfortable and safe. The most important advantages of this solution include:
- easy installation of flexible cables,
- the use of health-friendly, high-quality plastics,
- possibility of central and local regulation of air volume,
- small pressure losses,
- cleanliness of the cables, which is ensured by their smooth internal coating,
- ease of system maintenance.
The manufacturer also emphasizes the great importance of the OnFloor system for the health of its users. Ventilation favors allergy sufferers and prevents the development of mold and fungi while maintaining thermal comfort in the interior. It saves a lot of energy and is also a highly aesthetic solution, because the only visible element of the system are discreet decorative grilles.
5-year warranty from Zehnder
One of the biggest advantages of Zehnder ventilation systems is a 5-year manufacturer's warranty. It declares the highest quality of all installation elements, their perfect fit and optimal operation for a very long time. If any repairs are necessary, they will be made free of charge as soon as possible, and a team of experienced professionals will be responsible for them.
