How we approach extractor fans in Hemel Hempstead

The rate a fan delivers through a real duct run is often far lower than the number on the box, which is why we size to the room and test the result. For England, Approved Document F gives minimum intermittent extract rates: 15 litres a second for a bathroom, 30 for a kitchen with a cooker hood (60 without one), 30 for a utility room and 6 for a WC.

Like-for-like replacement

A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.
