Working in Grangemouth
As well as Grangemouth itself (FK3), we survey in Falkirk, Alloa and Bathgate.
Being a smaller town does not change how we work in Grangemouth: free survey, written quote, one team. Fans fitted in Grangemouth bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. We check the duct route at Grangemouth surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of the Forth Valley 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
- Making good around the fan and checking that it extracts properly at the grille
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A check of the room, any existing fan or vent, and the shortest route to the outside
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.
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
Rules that apply in Scotland
In Scotland, the Technical Handbook also uses 15 l/s extract for a bathroom. A replacement fan rarely needs a building warrant, but forming a new bathroom may.
