"How do I prevent condensation happening in a house?"
To help understand this explanation the Football Explanation above should be read first otherwise it might not make sense. There are two ways the situation should be approached. Obviously you are not able to stop breathing or perspiring, both of which produce water vapour, but you should consider all other water vapour generating activities that take place in your home such as cooking, bathing, clothes drying etc. Whenever possible the water vapour unavoidably generated by these activities should be forcibly extracted at source directly to the outside. By doing this the amount of water suspended between the footballs (air molecules) is reduced thus there is less water vapour in the atmosphere to potentially be deposited as condensation. Even if the air is cooled it may still be able to support the reduced amount of water vapour. If forced extraction is not possible a correctly used small domestic dehumidifier would also considerably reduce the water vapour levels suspended in the atmosphere within a property.
The second approach to be used in conjunction with the above is to provide constant adequate dry heat combined with good levels of insulation. Not only will a constant supply of heat increase the surface temperature of wall surfaces but it will also increase the size of the footballs (air molecules) to perhaps beach balls thus enabling more water vapour to be supported in the atmosphere. If surfaces are kept warmer by insulation then the footballs will just bounce off with little or no contraction occurring and the water will remain suspended and not be deposited as condensation.
