Which towns do we cover in County Antrim?
Water across much of County Antrim 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. We check the duct route at Belfast surveys, because a short, straight run to outside matters more than the fan's headline figure.
What the job includes
- Making good around the fan and checking that it extracts properly at the grille
- 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
- A backdraught shutter and external grille, so cold air does not blow back in
- 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
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.
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.
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.
