Healthy home climate by proper ventilation
At the latest when the windows are constantly clouded with condense water or mould begins to grow on the walls habits
should be checked and perhaps thought over.
The answers to following questions might be quite helpful for you:
How often should I ventilate?
Your home climate hygrometer can always give you the answer to this question. Whenever the hygrometer display
exceeds the blue range specified for the room temperature it is time to ventilate.
How long should I ventilate?
The hygrometer can answer this too: In winter, when temperatures are cold, under approx. +5°C, a maximum of 5
minutes is sufficient.
If it is milder outdoors (5-15°C), about 10-15 minutes are necessary.
How should I ventilate?
Effective air exchange is only achieved by opening the window or glass door of a room real wide ("force ventilation").
There is no need to cause a draught. Simply tilting a window, for ventilation, is absolutely insufficient and a waste of
energy.
What should I do if I am out of house during the day?
It is absolutely adequate if you ventilate when you are at home. This should be done at least once in the morning before
leaving the house, once when you return to the house and once in the evening before going to bed. It is just as
important that you do not turn the heating all the way down during the day (minimum 16-18°).
Should I ventilate when it is foggy or raining?
This is also very sensible. Even very cold, wet air always has less moisture than normal indoor air. Besides that you
also need fresh air when the weather is damp.
How should I ventilate the cellar?
Cellar rooms are at risk in summer because the outside air contains a lot of moisture then which condenses on cold
surfaces. Cellar flats should therefore, if possible, not be ventilated when outdoor temperatures are over 15°C or a
dehumidifier should be used.
Is it possible to dry clothing in the home?
Perfect for this purpose is a drying room that can be continuously (except in summer or during frost periods) ventilated.
Clothes should only be dried in the home if the room is closed off and very well heated. During the drying the room
should be ventilated very often. COMFO-X is the ideal aid for this too.
