The need for efficient dehumidification is not just restricted to neither water damage, construction work, production processes, swimming pools and waterworks and other obviously damp areas. Buildings, valuables and people in all sorts of climates will often benefit from dehumidification in less obvious everyday situations. The outdoor air is never completely dry anywhere in the world, and indoors multiple sources add to the relative humidity of the indoor air: transpiration from people; steam from cooking and bathing; humidity emanating from production processes or the storage of damp goods; even building materials and furniture slowly drying out add to the overall humidity of a room. Due to ever rising energy prices, buildings are much better insulated than before. The insulation might keep out the cold, but it also reduces the air change and traps humidity. A sure sign is dew on on windows, which can easily turn into moisture causing damage to the woodwork.
