Working in Tiverton
As well as Tiverton itself (EX16), we survey in Exeter, Taunton and Exmouth.
Tiverton gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Tiverton homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. We check the duct route at Tiverton surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of Devon is supplied with soft water. 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.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
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.
