Which towns do we cover in Northumberland?
Supplies across most of Northumberland 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. If your Blyth home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply.
What the job includes
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Making good around the fan and checking that it extracts properly at the grille
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.
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.
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.
