Which towns do we cover in County Armagh?
Water across much of County Armagh is 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. Fans fitted in Craigavon bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
What the job includes
- 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
- 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A check of the room, any existing fan or vent, and the shortest route to the outside
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.
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.
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.
Rules that apply in Northern Ireland
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 Northern Ireland, ventilation is covered by Technical Booklet K, and building control is involved where a new bathroom is formed. There is no Part P, but the fan should be wired, tested and certified to BS 7671.
