Which towns do we cover in Edinburgh?
Supplies across most of Edinburgh are soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier. We check the duct route at Queensferry surveys, because a short, straight run to outside matters more than the fan's headline figure.
What the job includes
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- 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
- Making good around the fan and checking that it extracts properly at the grille
- A check of the room, any existing fan or vent, and the shortest route to the outside
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.
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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.
Rules that apply in Scotland
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 title deeds often require the other owners' agreement for a new extract vent, and in a listed building a new opening through an external wall can need listed building consent.
In Scotland, the Technical Handbook also uses 15 l/s extract for a bathroom. A replacement fan rarely needs a building warrant, but forming a new bathroom may.
