Working in Aston
In Aston we cover B6, B7 and B19; we also cover Birmingham, 1.5 miles away, and Washwood Heath.
In Aston, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. In Aston flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. If your Aston bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Water hardness varies across the West Midlands: some supplies are soft, others moderately hard or hard. Scale is a minor issue next to condensation, which is what a properly sized extractor fan is for. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
Rules that apply in England
In England, Approved Document F sets bathroom extract at 15 l/s for an intermittent fan or 8 l/s for continuous extract. Wiring a new fan alters a circuit in a room with a bath or shower, so it is notifiable under Part P.
