Bathroom extractor

[jrussuk]

Hi,
This may sound a stupid question. I have a in line extractor fan in our bathroom. I got a powerful line which should service a room bigger than the size we have. I was going to get a cealing fan fitted as well for two reasons. 1 I can’t stand the look of the plastic inlet and 2 I thought it might boost the extraction rate. Is this a stupid idea ???

1. do you need more extraction
2. is your inline fan got a timer on it
3. why not just replace with a single bigger unit, normally bigger will flow more air and can run slower thus quieter, but then you need to balance it otherwise all that nice hot air is just chucked outside while you are in the bathroom

I could do with more extraction. The steam from the shower seems to hit the wall opposite and condensation on that wall is a problem.
It hasn’t a timer. Runs on a switch outside the bathroom next to the light switches but we do run it a good 20 mins after showering.
The unit we have is a pretty large one. I replaced the old unit with a unit which should service a larger bathroom than ours

Does extraction improve if you crack a window open slightly?

 

[jrussuk]

Not really. We also have a trick event in the window. Also there’s a gap under the door and we always leave the door ajar.

Best thing you can do is leave the window open a little whilst the steam is being created and then leave door open with the window when finished a little just to create a through draught. The type of wall coverings/finishings can make a difference too.

The wall with condescension problem is currently bare plaster.

Well that's one reason, the moisture will soak in to that quickly as it's porous.

Once I decorate then if I still have problems. What do you think the next step should be? A larger in line fan? Would an extra ceiling fan work. Also have you any ideas for the actual plastic inlet. I hate the one I have. I will post a picture

 

[jrussuk]

This is what I want to replace.

Which extractor have you got?

Can you photograph the ducting?

Are the walls cold? Solid, cavity, CWI?

 

[jrussuk]

I’ll have to go in the loft later but the ducting is flexible plastic. The wall is cold. Don’t think it’s cavity as property was built in 1910

 

[jrussuk]

This is simler to fan in loft.

 

[JohnD]

"Similar"

But which one have you got?

Can you photograph the duct?

How many of the walls are external?

 

[jrussuk]

I’ll have to get into the loft later. 2 walls are external
