Enjoy optimum heat recovery with the Brink Renovent Excellent 400 balanced ventilation system. This MVHR system can change 400m³ of air per hour, suitable for larger dwellings. Houses used to have a lot of natural ventilation thanks to cracks and holes. Although this is by no means energy-efficient, it did ensure a healthy indoor climate through constant air renewal. Nowadays, houses are very well insulated and natural ventilation no longer gets a chance. That is why mechanical ventilation is necessary. If you want a sustainable and energy-efficient solution, go for a heat recovery system such as the Renovent Excellent 400 of Brink Climate Systems.
