Drying out water damage
It is difficult to give exact guidelines for how to approach a water damage situation, as both the nature and extent of water damage varies considerably. However, there are some general points that you should always take into consideration.
It is essential to contain the damage by sealing off the afflicted area as quickly as possible to avoid outside air or other sources adding humidity to the locale. This way you only have to deal with the water that is already in the locale.
It is equally important to remove the moisture as quickly as possible. In most cases it is beneficial to add heat to the room to increase the evaporation. This is especially true if the water damage occurred recently and the water has not had time to penetrate deep into furniture and moveables, or walls, floors and other parts of the building structure.
If the water has had time to penetrate deep into the building structure you need to use a larger dehumidification capacity to get quick results.
Empirical values are essential to ascertain the required dehumidification load. Please read the rules of thumb.
Water damage under floors
In the case of underfloor water damage, it is often necessary to tear up the flooring to replace the wet insulation. This is time consuming work and often it is both very inconvenient and costly as it renders the room virtually useless for as long as the repair work goes on.
In quite a lot of instances, however, a dehumidifier equipped to add heat to the process such as the CDT 30 S and CDT 40 S will spare you the inconvenience of breaking up all the flooring and save a lot of money.
Hot dry air is fed underneath the floor at one end by means of ducts from the dehumidifiers 1 kW heater. To ensure sufficient air supply the length of the ducts should not exceed 5 metres. The hot air continuously feeds through a hole at the other end, evaporating water from the insulation and taking up moisture as it passes under the floor. This allows you to use the room above the afflicted floor while the insulation is being dried out.
The theoretical calculation involved is extremely difficult. We advise you to use empirical values and read the rules of thumb.
