Working in Portishead
In Portishead we cover BS20; we also cover Nailsea, 3.5 miles away, and Clevedon.
Homes in and around Portishead vary, so we look at the floor, the walls and the water system before we price anything. We check the duct route at Portishead surveys, because a short, straight run to outside matters more than the fan's headline figure. If your Portishead 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.
Most of Somerset has hard water. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
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.
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 England
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.
