Our bathroom revamp is going to include an extractor - the room currently doesn't have one. However, I am having trouble deciding what to go for.
It will be wall mounted, two layers of brick to the outside wall so a very short duct. Will use a timer system plumbed in to the lighting circuit, via 30mA RCD and three pole isolator. (Yes, I know I need to get this certified/done by Part P person - for the 8inches of wire that will be actually in the bathroom!)
The room is 14.5m3. I have read varying advice for what capacity of fan to get. This room will have a shower in, so some advice is 15-20 times the volume - which would mean a fan of 215m2/hr. Other advice would indicate less than that = such that 85 or so would be sufficient.
Manrose do some at that level (230m3/hr) at 150mm duct size, which does seem pretty beefy. They also do many at the 85 level seemingly aimed at bathrooms.
After all that intro, all I really want to know is - is 230 overkill, and should I just stick with around 85m3? Are Manrose a decent enough make? They seem cheaper compared with the others.
TIA
