Several of these things can be linked with property ‘damp’ problems in bathrooms and can in fact be related ked to condensation problems (and then mould problems). In our article about the signs of a water leak, we mentioned how there are a few signs of a leak to watch out for. On this setup, 4.3m/s is approximately 430m³, which for an 11.78m³ bathroom is 36x more so again, more than enough for that size of bathroom. But is it big enough for the larger bathroom? Lets take a look. That said, it is an in-line extractor fan placed and ducted in the loft (venting to the outside to avoid loft condensation!) which is higher rated and in a larger bathroom, so the results are expected. You can see that below, we are testing the existing fan in the ensuite bathroom mentioned above.Īs you can see this has a reading of 4.3m/s which is much faster then the other. Importantly, to give a better reading you need an anemometer with a hood on it to give a good ‘seal’ around the fan to give better more accurate readings. There are tests you can do on a bathroom extractor fan, using an anemometer. That is 7.64 times per hour not really enough aloneīut how do you know if your extractor fan is sufficient, especially if you do not have the original instructions, know the model number or (perhaps more commonly) it is old and not running at full or original capacity / speed. ![]()
