An extractor fan can kill you!
Did you know that in certain parts of the U.S., it is part of the building regulations that every new home is ‘pressure tested’ to make sure it has enough ventilation?
By the way, last time you bought an older house, I bet you had to have en electrical survey. But I bet no-one made you have the gas appliances checked, did they?
In a modern, well-insulated home, if you turn on the bathroom or kitchen extractor fan, the pressure drop created is enough to draw fumes back down a chimney or flue, particularly if that flue or chimney has not ‘warmed up’ yet.
