Working in Wellingborough
In Wellingborough we cover NN8; we also cover Rushden, 4 miles away, and Kettering.
In Wellingborough, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For windowless bathrooms in Wellingborough homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. Fans fitted in Wellingborough bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of Northamptonshire are hard. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. 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
- A backdraught shutter and external grille, so cold air does not blow back in
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
Decisions to make first
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
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.
