New buildings commonly use a mechanical ventilation system with heat recovery. When renovating older buildings, we recommend the VILPE ECo Ideal Wireless control system. ECo Ideal is an automatic regulation system for roof fans, which adjusts ventilation according to indoor air quality by removing excess moisture and carbon dioxide. To complete the ventilation system, supply air is also needed to replace the bad air. This can be done with an intake vent: for example, the VILPE Wive. ECo Ideal is also suitable for ventilation in recreational homes, warehouses and garages.
