Drying to deal with problems with condensation damp
Condensation damp generally occurs in basements when moist air penetrates the basement
in summer and condenses on the cold walls of the basement. We recommend that you de-
humidify the basement, room by room, in continuous operation. To start, run the device in
continuous operation mode until you see that the amount of water that you are emptying out
of the tank each day starts to reduce. Then move the device to the next room. Once you have
dried all the rooms in this way we recommend that you select a central location for the device
and then run it in automatic mode. We recommend a humidity setting of approximately the
middle setting of the regulator knob. This method of dehumidifying is more efficient in energy
terms than dehumidifying in automatic mode from the start, because if you do the latter the
device will switch on and off a lot.
Drying to deal with building defects or water damage
In the case of building defects or water damage, the cause needs to be eliminated first. Once
this has been done the rooms can be dried using condensation driers such as the Demecto
30. In this case the dehumidifier is run in continuous operation mode. The ambient tempera -
ture needs to be at least 20°C (but not above 27°C). Additional heating can be provided by
an electric heater if necessary. Gas radiant heaters are not suitable! To generate the air circu-
lation required, fans can be used in the room.
Please note that the insulation layer may also need to be dried, depending on the nature of
the building defects. This will have to be undertaken by a specialist firm.
Recommended humidity levels for rooms
As a general rule this is dependent on the ambient temperature. The higher the tempera -
ture of the room, the lower the setting for the relative humidity needs to be, otherwise it will
encourage the growth of fungus or mold in the room. A pleasant level of humidity is between
35% and 65% relative humidity, depending on the ambient temperature.
The following diagram provides a point of reference for the optimum level of humidity at diffe
-
rent ambient temperatures.
The diagram is based on the assumption that temperatures >=20°C are for living quarters
and temperatures <=20°C are for basement quarters.
