Ventilation systems: The fresh helpers in the background

It is hard to imagine modern buildings without ventilation systems. They keep the indoor air basically clean and fresh without you having to take care of it yourself. Manual ventilation through open windows or even doors is almost a thing of the past with a ventilation system.

What can ventilation systems do?

Ventilation systems usually consist of one or more ventilation units that provide air exchange in rooms and entire buildings. The different units of a ventilation system work as a team. For example, it is possible to take into account the different frequencies of use of the different rooms and automatically ventilate the much-used study significantly more intensively than the rarely used guest room.

Ventilation systems exist in various designs. They can be controlled centrally or decentrally, equipped with heat recovery or sometimes even replace the heating system. But no matter which version you choose: Thanks to your ventilation system, you will not only always breathe fresh, but also filtered outdoor air. Because before the ventilation units release the air from outside into the interior, it is passed through various filters. Pollen and pollutants must therefore stay outside.

Where are ventilation systems particularly useful?

Ventilation systems ensure an all-round healthy indoor climate through regular and demand-oriented ventilation. This is not only good for us, but also for the walls, because mould is a nuisance of the past with well-coordinated ventilation.

In new buildings and particularly energy-efficient houses, ventilation systems are not only an option, but a must. Since there are no cracks or leaks in the masonry, "automatic" ventilation is not possible. Therefore, ventilation systems take over this task. With their constant work, they always keep the air fresh and prevent the formation of moisture in room corners and behind cupboards.

The advantages and disadvantages of ventilation systems

On the disadvantages side, there are the purchase costs. This means an additional expense, which naturally becomes noticeable especially when you already have a lot of expenses (for example, when building or moving house).
These costs are offset by a number of advantages.

For example, systems with heat recovery save a lot of heating energy and thus also costs. Often, these devices even save more money over their lifetime than was spent on their purchase. Owners of a ventilation system always enter a home with a fresh indoor climate, no matter how long they have not been at home or have not aired the room. Fresh is not to be confused with cold. The temperature can be controlled just as much as the ventilation intensity per room.

Thanks to the fact that most windows are closed, there is even greater protection against burglary, because leaving windows open while you are not at home is no longer necessary with a ventilation system. And those who live on a busy road or near railway stations, airports or industrial areas will also appreciate the fact that it is now much quieter within their own four walls thanks to the closed windows.

However, this is not the end of the advantages. Thanks to the demand-oriented, automatic ventilation, mould and moisture no longer stand a chance, and allergy sufferers will also quickly notice what they have in their ventilation system. In addition, pollutants that have accumulated are quickly led from the inside to the outside and new pollutants are not allowed in in the first place. So the air is not only fresh, but also healthy.
