In line with modern residential building regulations to limit heat loss, modern domestic properties are made as airtight as possible. The reduction in natural fresh air reduces moisture transfer and has the knock-on effect that the air becomes dry, causing the occupants to suffer from symptoms such as dry throat, skin and eyes, headaches and eczema– particularly at night.
Antique furniture, timber floors, musical instruments and pictures can also crack due to the low humidity levels – possibly reducing their value, affecting their appearance and making them difficult to insure.
Residential heat exchangers and other energy efficient technical additions to a domestic building assist with temperature control and the removal of unwanted moisture, but it is important to consider the air condition as a whole and this includes creating a stable relative humidity.
Humidity control is particularly relevant where vulnerable people require humidity control for comfort and wellbeing to ease breathing and skin irritation issues.
In addition, properties with high value items such as artwork, musical instruments and antiques require humidity control to keep their value and condition. Whilst more short term cigars, wine cellars and fur rooms require conditioning to maintain quality.
