Which towns do we cover in Clwyd?
Most of Clwyd has moderately hard water. 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. If your Wrexham bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
What the job includes
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- 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.
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.
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 Wales
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.
Wales has its own Part F with similar extract rates, and its own Part P, under which new fan wiring in a bathroom is notifiable.
