Heat recovery ventilation – do I really need it?

Homes and buildings are becoming increasingly more airtight to save valuable energy. It is, therefore, all the more important to ensure a regular air exchange in order to prevent consequential excessive humidity and mould growth, as well as the decrease in the resale value of the building resulting from this. As opposed to airing by opening the window with the heat escaping through it, the HRV system is energy-efficient due to the integrated heat exchanger, and - what is more - it prevents fine dust and allergens from entering. Our profi-air makes your home a cosy place to live.
