How to prevent Condensation

There are several things the inhabitants of a house can do to significantly limit the condensation that occurs, many of which cost nothing. Firstly, and perhaps quite obviously:

    • reducing the amount of water vapour produced can be very beneficial
    • drying clothes outdoors when possible
    • ensuring cooking pan lids are and that kettles are not left boiling for unnecessary time can all help
    • certain types of heaters such as paraffin heaters can create lots of water vapour so these should be avoided

Another way to reduce condensation problems is to keep the vapour contained within the bathroom or kitchen. By closing doors when cooking or showering, moisture is kept in a few rooms instead of spreading to the whole house. Then by ensuring these rooms are suitably ventilated by keeping a small window open or turning on the extractor fan, condensation will be limited. One of the best and sure fire ways of reducing condensation is through appropriate ventilation. Allowing the warm, high moisture air out of the house whilst letting cooler, lower moisture air in will help significantly.

Another route to reducing condensation takes a different kind of approach. Instead of reducing the amount of moisture that could condense on cold surfaces, limiting the cold surfaces can be equally effective. By keeping the home warm during the colder seasons, there will be less chance for moist air to condense. It is important not to heat the house using paraffin or portable gas heaters as these generate lots of water vapour, as mentioned above. Furthermore, the heating of a house is most effective when done at a low level but over a long period of time (as opposed to for a few short, but hotter, spells) to ensure the windows are always slightly warmed.
