Water across much of South Yorkshire is moderately 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. Fans fitted in Sheffield bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Making good around the fan and checking that it extracts properly at the grille
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A backdraught shutter and external grille, so cold air does not blow back in
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
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.
Rules that apply in England
A bathroom needs extract ventilation when it is newly formed, and on a refit an existing fan should not be replaced with a less effective one. The fan and its wiring must meet BS 7671 for the zone it sits in, on a circuit with 30 mA RCD protection. In a flat, the lease often requires freeholder consent for a new extract vent, and in a listed building a new opening through an external wall can need listed building consent.
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.
