Working in Llanelli
In Llanelli we cover SA15; we also cover Gorseinon, 5.2 miles away, and Swansea.
In Llanelli, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Llanelli bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. For windowless bathrooms in Llanelli homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Supplies across most of Dyfed 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.
What the job includes
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A backdraught shutter and external grille, so cold air does not blow back in
- 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
Decisions to make first
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.
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.
Rules that apply in Wales
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.
