How to properly ventilate your home – tips on how to do it correctly.


But open the whole wing as far as possible and make sure that it is pulled through. Then the complete air exchange – the energetically ideal way to ventilate – already succeeds in about two minutes, even faster at sub-zero temperatures. The exchange is achieved when the feeling “Now it’s getting cold” arises. The tilting position – especially preferred by shivers – is almost ineffective and costs a lot of heating energy.


Not only in the morning to change the damp bedroom air and the stale air in the rest of the apartment, but also in the afternoons and evenings when you come home. Then the room is ideally prepared for all the breathing, cooking and shower humidity that we produce during living. Fresh air is drier than stale air and can absorb more water vapour.

Before going to bed, you should let the moisture out again, otherwise it will deposit on the (cool) windows at night, and this means a permanent risk of mould. If you are at home during the day, it is best to ventilate again in the morning and in the afternoon.


Moisture is also a reason why doors should be kept closed between rooms of different temperatures. It enters the cold room with the warm air and condenses there. Apart from this, heat is distributed poorly between two rooms, so that only unnecessary energy is consumed when heating the bedroom from the living room.


Every degree of room temperature that you do without saves about six percent of heating energy. Marianne Gockeln (energy consultant for buildings) calls values between 19 and 21 degrees “reasonable”. Normally you don’t freeze, have a healthy room climate (with the help of shock ventilation) and still save energy.


It’s a waste of energy to turn down the heating in the evening or when you leave the house.

If you allow rooms below 18 degrees Celsius to cool down, you will use a disproportionate amount of energy to reach a comfortable temperature again later on. Dormitories may become slightly cooler at 16 degrees, colder air cannot absorb the moisture emitted by the sleepers. It does not make sense to set the heating to “frost-free” even during a weekend trip.
