Extractor fan installation UK - choosing and installing an extractor fan

- It's time to fit the extractor fan for our utility room and downstairs toilet so I thought I'd share some thoughts behind our choice of fans and some installation tips.
According to the Building Regs all new build (including within house extensions) utility rooms with any kind of plumbing need an extractor fan with a minimum extraction rate of 30litres/seconds. Although it's not mandatory to have an extractor fan in the downstairs toilet we also decided to fit one here.
Thanks to Gil-lec for supplying the fans.

*Works great with **Fastly.Cool** , exactly as described. Love the fact that it can push, pull, or exchange air with the push of a button. The remote is a nice bonus too!*
Great informative video! As an assistant QS this has help me get my head around the installation
Well explained on why you need a extraction fan to fight the problem of moisture and prevent the build up of mould growth thoughout your house... 10 out of 10 from me... gr8 video...
Hi Georgina, one of the best descriptions of damp / humidity I've seen. Ventilation & background heat = perfect conditions 👌
Most people don't realise just how much moisture we produce ( even just breathing)
I would also say if it dry enough to hang your linen outside then open windows & ventilate. If it's too damp to hang linen outside then close your windows - easy.
Excellent video, thank you.
Hope you have a great day.

Thanks Tim and a good tip 😀
Really useful video and professional production! 5 stars - I bought mine after watching this.
Thank you. Glad it was helpful! 🙂
Great video very informative. Like your wall colour in utility.
Thank you! 😀
THANK YOU! Excellent video. I moved five weeks ago. There are vents on the outside that I assumed were linked to the utility room/downstairs toilet "extractor" fan, and the cooker hood (above a GAS stove) fan. But no! The cooker hood chimney reaches up to the ceiling (lovely grease patch) but doesn't leave the house. Upstairs bathroom fan blows steam into the loft (had no idea this was a thing!), and the windowless downstairs toilet/washing machine room has a fan to nowhere. I'm so shocked that this four-year-old house could pass building regs.
That's unbelievable! Thanks for sharing.
Thanks. I found that really useful.
Excellent video
Ive just had the envirovent filterless extarctor fan fitted to my bathroom by the housing they do make a hell of a diffrece to the bathroom feels fresher it runs on trickle mode then boosts when the humidity rises automatically recommend
Hi I have a question.
If the flexible ducting has tears inside, does it need replacing or it doesn’t matter?
My main worry is damp might get to the brickwork instead of venting outside?
Great video
Glad you enjoyed it : )
Wish this vid was around when we installed the extractor.
Do you have any suggestions for the insect mesh on it's own?
Would be good to add to stop the creepy crawlies in summer.
Seen stainless Steel and fibreglass
Hi this is great and so informative! I was sure it was 300mm from the boiler flume! I was wondering would this be ok to use in a kitchen instead of an over the job extractor good? Thanks again.
unfortunately the people who converted part of the old garage into a utility in our current house didn't fit an extractor, and the occasional build up of smells and damp when we keep the door closed to the utility needs dealing with, currently looking at how we rectify this, looks like we are going to have to use an inline fan through the new garage that's in front of the utility and out the front wall, or soffit, our outside wall is right on boundary and roof ventilation also isn't an option. still going for the humidistat controlled option as this makes most sense, you can get some nice remote stats, just a shame nobody seems to do a wireless version as they do in thermostats. only bit of the work we won't be able to do easily without using surface mounted cable is the connection between the stat and the fan. great informative video that confirms everything I've learnt about active ventilation.
Glad it was useful - good luck with your project : )
inspired!
My downstairs toilet is getting too humid and causing problems, but the room is quite narrow and theres no space on the wall to fit an extractor, fan since its taken up entirely by a upvc window.
Any idea what's involved in fitting one in the ceiling? I thought regulations would require it to have an isolating wall switch (aswell as the light pullcord)?
Could it be fitted from downstairs or would the fitter need access via the floorboards in the room above? Thanks
Probably worth asking expelair as they're the experts - I'm pretty sure you could fit it from downstairs though
I bought my house in April and I've just noticed that the bathroom extractor fan extracts into the loft!
Oh no! It’s not uncommon unfortunately 😬
Won’t the bathroom extractor fan allow lots of cold air in in winter?
We have an extractor fan in the shower cubicle with no bulb in it,in the same bathroom we also have 3 more modern ceilings mounted lights we wanted to fit the bulb , but i have assured my wife that, the bulb in the shower will be a special one and not the same as the other three,, am I right and if so which bulb do i fit,, PS the fan works fine and extract to outside. Can you advise, please, Yes they are all switched from the switch outside the bathroom?
Yes I think you will need a special bulb but you'll have to refer to the manufacturers' instructions which should give you the info you need.
Any update on this? How is the extractor?
Hi Georgina. Very good video. Can you help me out. I have damp in my wooden shed and need to put an extractor fan in there to stop mould etc. The shed frame work is 4 inch by 2inch and the cladding is 22mm loglap. I can easily put an extractor fan between the studs as they are 16inch on centre. Can you recommend an extractor fan which won't give a big protrusion beyond the outer shed wall. I would also like a one way draught flow as well. Many thanks
I would probably look at where the moisture is coming from first - through the floor, wallks, ceiling - is the shed heated? It might be difficult to get rid of the mould if it's not regularly heated and well insulated. In terms of a fan - I don't know of any specifically but Xpelair has a decent range so I'm sure they would be able to help. 😀
Would you add silicone to outside as well?
Yes you could do, especially if there’s a significant gap between the plate and the wall
Do u have the link to the mesh for the grill?
Here you go: www.amazon.co.uk/dp/B004X4RYFS/ref=cm_sw_r_wa_awdb_imm_t1_nYn2Fb60VAMEH?_encoding=UTF8&psc=1
@@GeorginaBisbyDIY Thankyou! Was after just the mesh but might buy a sheet to cut and insert. Or change for the one in link
Does the mesh ever get clogged up and you have to remove or change it?
You didn’t show properly the inside bit of the kitchen .
30 litres of air per second at 1:14 ????
wouldnt that much suck up cats and small children and dogs ?
No George, 30 litres per second is possible, air is a lot thinner than milk you idiot!
who are you calling me an idiot ?
@@DICEGEORGE Uh, you ok there buddy?
yeah, that's the same minimum rate for intermittent extraction as a kitchen hood, if you use continuous extraction it comes down to 8l/s , kitchen general extraction (not using local to hob extraction) is 60l/s. high extraction rates do not always equal high velocities and hence suction to achieve this air movement. Its volume of air over a set time, because it's through a large diameter pipe, typically 150mm diameter it can move high volumes at quite low velocities. 30l/s equals about 65 cfm (cubic feet per minute), most domestic Vacuum cleaners move between 50 and 100 cfm, but a vacuum uses pipes equivalent to around 50mm, thats about 11% the cross sectional area of an 150mm duct. hence a vaccum cleaner moving 60ls has 9x the air velocity of an extractor. think cats and small children can rest easy
Tell this to our housing association! We have fans which vent back into the room, so pointless.
How frustrating! Poor ventilation is everywhere in this country unfortunately!
Key points for me when choosing extractor fans are extraction rate, noise level (for bathrooms try to get below 30dB) and I suppose in todays climate the wattage (how much will it cost to run).Delay on timer and delay off timer functionality is also good to have. How the fan exhaust connects to the ducting is also crucial. No point in having a fancy new fan and the extract air is not being efficiently channelled away. Your wasting energy and not getting as good extraction as you could if you don't consider this.
can I borrow your dad's core drill
I can only presume you are Roger's daughter ?
Yes I am.
Ha, I assumed the same, thought I'd look down the comments before posting it, and there it was 👍
I was wondering too as I follow rogers channel 😁
