Ground Floor Bathroom Extractor Fan Query

[lmike19]

Hi. My current axial Xpelair model 92614AW ground floor bathroom extractor fan is installed in zone 1 and doesnt work efficiently at all. Its wall mounted but doesnt go straight to the outside as there is now an extension on the back of the bathroom. I think either I need to get a more powerful fan (going by Google search of data sheet, looks like the max air flow is 76 m3/h) or due to ducting I believe to be over 1.5m, I require centrifugal fan.

So I have some questions regarding this - should I try a more powerful axial IP65 fan wall mounted, or should I try to make this centrifugal and be mounted on ceiling (dont particularly want a big unit on the wall). If I went to mount this on ceiling, can existing ducting be extended? The wall in bathroom sticks out slightly so I think I can take duct this route if need be. Finally, And are there any regulations for this being installed on ground floor in first floor void, apart from adequate access being available?

Thanks

A 230/240 volt fan should not be in Zone 1

How is it vented now?

Ducting in a first floor void is acceptable if it is not a separate dwelling above.

I'd like you to show me the regulations where it states a 230/240 volt fan cannot be installed in Zone 1.

Ventilation equipment are one of the few items that are explicitly listed as being allowed in zone 1 (701.55 Current-using Equipment), with the caveat that they are suitable for installation in said zone according to the manufacturer.

I have installed 230v extract fans in zone 1 the unit being specified as suitable for zone 1 by the manufacturer.

I did not say it was a regulation, just a pretty stupid thing to do IMO, and now we will go down the "some installations" yada yada yada.

Anyone going to give the OP some positive feed back instead of the usual guff.

You say it should not be in zone 1 so can you back this up aside from 'It is a stupid thing to do'.

 

[Mike Johnson]

Do you not understand what IMO stands for?

 

[westward10]

Well you gave an opinion so what are you basing it on.

You didn't say 'IMO' in post 2 though. You stated it as a fact.

Absolutely nothing wrong with it. Napit assessor asked me about a fan I’d installed on a recent rewire. I said it was ok for zone 1, as per manufacturer’s guidance, and no more questions asked.
