The Berlin consumer advice center knows what to consider when installing a ventilation system. Among other things, it points out that appropriate specialist planning is required, that the most efficient devices have the EU efficiency label A+ and that the purchase costs for ventilation systems with heat recovery can be financially subsidized via the federal subsidy program for efficient buildings (BEG).
According to the consumer advice center, ventilation systems are not only practical because they evenly supply fresh air to living spaces, extract stale indoor air and remove moisture. In some cases, they may even be necessary, for example in some new builds or renovated properties. This is the case if the windows and doors are so well sealed that opening them is no longer sufficient to protect against moisture.
According to the Berlin consumer advice center, a ventilation system can ensure continuous, needs-based ventilation. On the other hand, the filter systems in the ventilation systems can keep dust, pollen and insects out of living spaces. A distinction is made between centralized and decentralized ventilation systems. Centralized ventilation systems are suitable for new buildings, while decentralized systems, which can be retrofitted, are suitable for existing buildings.
