This is the amount of steam we produce day by day
An average of up to 15 litres of water are absorbed by the air as steam in a four-person household per day. Due to cooking, bathing, plants - or simply breathing. One person, for example, exhales up to one litre of water per night.
To discharge this humidity, the windows would have to be opened every two hours - in summer and in winter. Convenience ventilation systems constantly provide sufficient air circulation and continuously discharge the humid air from the house. Mould damage is avoided and your building fabric is protected in the process.
