Its quite clear that they way we are using our house is creating high humidity levels.
Can you get useful information from a £30 meter from Maplins et al, or are they little more than a gimmick at that level?
What I would be interested in is to measure the current level in each room, and then work to reduce it, and take qualitative values as I go along. Obviously to a certain extent it is the the qualitative data thats important, at the moment I know there is an issue as we're getting stupid amount of condensation on the windows, frames, and the uninsulated sections of the sloping ceilings to the point its running down the walls, but curiosity would like to but a figure on it if I can for a sensible price.
Key areas are the bathroom and kitchen. Use lids when boiling/simmering water/food Close doors when cooking/showering/bathing to keep the water vapour in the room brush of as much water as possible down before toweling Use a window squeegy to get excess water of shower wall/surround once finished( also help with limescale staining) Use extractors fans whilst cooking/showering or open a window in these rooms whilst doing the above Wipe any condensation off windows etc each morning with a cloth and dry outside Dont dry washing indoor unless you have to. Perhap use a dehumidifier in specific drying room close the toilet lid ? do use : Ventilation Thermal blinds Pressure cookers MHRV/whole house HRV Built in wardrobes often get condensation in the back of them. ensure that all internal surface temperatures are above the dewpoint for the relative humidity in the house Average source, break down - 45% from showers, 35% from drying clothes, 13% from cooking, 7% from breathing/sweating Improve/upgrade you windows
