Extractor fan for bathroom that is draft proof

cbrady9

Hi All,

My parents house has two bathrooms both fitted with extractor fans. However due to where they live the draft and heat loss that these two fittings cause is unreal. The holes are on the wall, and it is a 4 inch wavin pipe that connects the inside to the outside. There is a static grill fitting on the inside and outside with a cover over the outside grill which is supposed to stop drafts but its not working well.

What they are looking for is an extractor fan that will close the hole completely when the extractor fan is not in use to stop any drafts and only open when switched on. Has anybody any advice or recommendations? Based in South Dublin but they are also willing to buy from the internet.

Thanks for reading.

Look at some of the more expensive ones at the bottom. They only open when moisture/humidity/heat is detected.

I think the agent for Airflow fans is Core Electrical.

if u can get at the ducting..u mgiht be able to add another damper in the middle to help, i seen foklks here on boards use them for say cooker extractors..

Many thanks almighty1, Hoagy & tred for your replies.

almighty1 - I take it the fans your saying I should be looking at are called "HUMIDISTAT". These only open when in use and are obviously closed when not in use. This is exactly what my parents were looking for only we didn't know they were called HUMIDISTAT. At least know I know the name of what I'm looking for. Cheers

tred - I'll suggest this to my parents as a cheap alternative but I think they're looking for HUMIDISTAT one. Thanks.


Has anybody got links for supplier of HUMIDISTAT extractor fans at reasonable prices. B&M or Online?

I've had a look through the www.tapsforless.ie web site from almighty1 and the extractor fans with the front shutter that automatically opens and closes to stop draughts are priced between 221.95e and 352.09e. More expensive than I thought they would be unfortunately. Any suggestions or links where I could get something similar at a better price?

Humidistat is not a brand name, it's a humidity sensor which is fitted to control the fan, sometimes it's built in to the fan.
What you're looking for is a fan with an Iris shutter, for example the Airflow type mentioned above.
The fan can be controlled by the light switch as normal, or by a humidistat, but it's not necessary.

Taps 4 less went bust last year by the way, the website is only for reference.

Hoagy

Vortice make 4inch fans with automatic shutters, ATC are the distributors, they're available in most electrical wholesalers.

cbrady9

Thanks for your quick reply Hoagy. I was aware Humidistat was not a brand name but thought this bit of technology would be helpful in any internet searches. However from what your saying this option does not necessarily guarantee the automatic shutter that I'm looking for which would stop draughts so perhaps Iris shutter as you suggested would to be a better search term.

Cheers

How about something like this.http://www.batticdoor.com/bathfandraftblocker.html

Thanks fergal.b for the Link and Video. I've never seen this product before and it could turn out to be a cost effective way of fixing the problem I've found their product on ebay and appears to be around 32e delivered for each item from the US.

Ebay Link: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=161012162899

Does anybody know if this product is for sale in Ireland or if it could be got online anywhere else for cheaper?

muffler

The damper itself can bought cheap enough here.

I havent checked if they deliver here or not but parcel motel would get it sorted.



Edit: The last 2 sellers here will deliver it seems.

cbrady9

Hi muffler. I appreciate you finding the links for the Backdraught Shutter on Amazon but I think the product fergal.b was suggesting was an In-Line Back Draft Dampers. You'd have to view the full video to see it or click on this link http://www.batticdoor.com/bathfandraftblocker.html

Appreciate you looking though

am i right in thinkin that the humidstat extractor fan will only turn on when the shower or bath taps are on and the heat and humidity gets to a certain level in the bathroom ?
so you can turn on the bath light to go to the toilet and the fan will not come on ?

That's correct.

I've found this one on an English web site: http://www.extractorfanworld.co.uk/airflow-icon-15-210-p.asp

Seems to be exactly what I'm looking for. Can anybody see anything wrong with the spec on this as it appears to be a good bit cheaper than what I expected?

Two delivered to Ireland = 96e

i was speaking to the lads in atc in balymount today and they told me that a humidstat fan is rather pointless as it wont switch off all the time due to the high humidity in the bathroom , it would just keep on running for ages .
does anyone here have a humidstat fan in their bathroom and if so does it switch on and off like its supposed to?

the lads did give me a good solution for keeping the fan off when the bathroom lights are on . they said something about putting the fan on its own isolation switch so that when you want to have a shower you hit the switch plate outside the bathroom for the shower and you also hit a switch to activate the fan . has anyone got this done in their house ?

I will be purchasing one soon and I think having it linked to the bathroom light is the best option. If you do purchase and use then please post back your experience.

My current fan is set up this way. I have an isolation pull-cord for my shower that is linked to the electric fan but sometimes I forget to turn it off.

so when you pull the pull-cord for the shower unit then the fan comes on too ?
my bathroom is wired with the shower isolation switch outside the bathroom on the wall beside the bathroom light switch . the lad in atc said something about installing a 3rd switch on the wall for the fan unit or linking the fan into the shower switch plate .
would this be safe to do this with regards the electrical and building regulations ?
i dont want the fan comming on when i turn on the lights just to go to the loo or brush my teeth at night .

oh and i bought a vortice lineo 100 t-vo inline fan from atc today some size of a fan allright extracts 180m3 of air per hour on its slow speed setting and 225m3 air on its high speed setting . also got fully aluminium insulated flexi ducting too, 10 meters of it .

you need to measure the size and volume of your bathroom in order to find out the correct size of fan to buy
you multiply the length by the the width by the height of the bathroom to get the volume and work out the right size fan that you need .
thats what the lads in atc told me today and helped me out with , i brought my measuremennts with me and they helped me to choose a fan to suit .

I have an extractor fan fitted in the celing of my bathrooms, and when it is not working, there is a terrible cold draft coming from the roof.

The fact of the fan coming from the ceiling is a grill like.
Are there any covers I can get for this?

Thanks to all the posters I have found this thread very interesting, having had a new extractor fan fitted to the bathroom the other day, with a massive draft coming down it.
