Sometimes central ventilation is optimal. For example, if it can be planned from scratch for the entire living area in a new building with maximum efficiency. Or as basement ventilation, where a smart control system ensures condensation, mold growth and typical musty basement odors for the entire basement floor under sensor control.
A decentralized living space ventilation system with heat recovery is often ideal for renovations. It is ideal for retrofitting small apartments, offices or bedrooms, for example, where installation costs are manageable. In addition, these systems are very quiet and extremely energy efficient.
Sometimes, however, single units in only some rooms such as toilets, bathrooms, wellness rooms, utility rooms or garages are the best solution. Control modules allow the fans to be optimally adapted to the task at hand and automated. Combined with properly executed window ventilation in the rest of the apartment, this creates an inexpensive, yet energy-saving and comfortable solution.
The advantages and disadvantages, and then the appropriate system selection, are best made together with the architect or builder and the installer who will plan and implement the ventilation design.
