Working in lofts is the worst believe me.. All the hard work & effort is Much much appreciated. ❤

[@muffinbubble]

Appreciate all the efforts. Definitely sound from down near my way (Norwich).

[@RB-xg2vz]

One tip I picked up for CRJ Electrical channel is to put rubber grommets (the type you use in metal back boxes) under the 4 mounting points of the fan and then screw the fan down - reduces vibration noise.

[@TheDIYGuy1]

Sounds like a great tip that and something I’ve never done 👍

[@freddieleethompson3536]

I do the same but use tap washers.

[@bobbeats]

Do you understand how an AV mount works? What he does with the grommets achieves nothing, still amazing what useless information you can find on YT

[@kuk3411]

You can also take two pieces of ply screw the first to a joist and attach the second on top with beaded silicone lowers the amount of vibrations through to the joist

Fitted one of these manrose fans a couple of years ago and it's so much better than the small inline fan type as you say. My only regret is not upgrading the ducting at the same time to the insulated type. I'll have to get a handyman to do it now as access is so poor into my eaves. Good video and you've got +1 subscriber from me. Cheers

Absolutely 👍

[@DTech101]

I always use ridged pipe stops turbulence and the build up mould in the duct. You said hard to find a fan with that extraction rate but for my downstairs bathroom fan installed over the shower area ridged ducting under the floor board this is the answer Airflow iCON60 Circular Extractor Fan for Large Bathroom, Utility Room or Kitchen 280mhr/78 ls but it’s a beast! PS I would get a humidity sensor wired up they do one that will work with that fan works good 👍🏾

[@dougle03]

Now I know the manual shows flexible ducting but.... Air ducting is always better when the inside of the duct is smooth. For such a short run I'd have been using 4" tube with an insulated wrapper. the rough surface in flexible ducting slows down the air travel, it causes turbulence and reduces the efficiencies of the fan. Perhaps not a problem for this install since it's a short run, but worth using a couple of lengths of tube between flexible angle joints. Cracking video, and I could feel your pain filming in that heat... 👍👍

[@flyingwhiteindian]

I dont understand why the tube has to be insulated - isnt it just taking the air outside. What does the insulation achieve/

[@dougle03]

@@flyingwhiteindian In the winter if the duct was not insulated it would get very cold and the steam would condensate in the duct before getting outside which is not desirable.

[@narrowboatlongpod4176]

@@flyingwhiteindian Condensation forms and runs back inside. You can get traps to take this away but it's not usually practical.

I installed the Timer version of the Manrose fan over the shower and also have an always on version (set to lowest speed) in the main part of the bathroom. Did this late last year and we've had no issues with condesnation, mould or "lingering smells" :) Must admit I'm surprised at how quiet these fans are, no need for anti-vibration measures at all.

These fans need fusing down which I did via a spur with a 3a fuse, I didn’t realise that you could get a fused isolator. Live and learn. Great video

[@neiltrevatt]

Did you have a fan with a timer if so how did you fuse both sw & permanent live

[@cgo225]

Thanks for the vid..... I've just had my new extractor fitted used solid tubing with a slight fall to the outside vent to drain any condensation to the outside, also added rubber grommets under the fan to minimise vibration, plus removed the flyscreen to prevent build up of fluff/dust and added a backdraught flap which keeps the bathroom draught-free especially in winter.

[@TheDIYGuy1]

👍

[@RogerHolden]

I've installed one of these, but only after first buying the version without a timer - so be aware that that exists. It didn't even cross my mind that they wouldn't have a timer, thus didn't check the spec, like you wouldn't check the spec of a car to check it has a steering wheel! Screwfix brilliant as ever and exchanged it for the (more expensive) timer version. I've also turned mine down to the lowest power setting as thats fine, and it was surprisingly noisy on medium or high.

[@johnny71c]

You are inspiring me to do the same in my bathroom. I have a wall mounted Envirovent and still have the same issue with condensation on the walls window and mirror

[@TheDIYGuy1]

👍 go for it. Wall fans aren’t the best

[@kn4cc755]

Independent of this video, I installed a similar fan about a year ago. It works well. Too well. With it at maximum speed (mine is variable), it is louder than a 747 on a short takeoff roll.

[@TheDIYGuy1]

They are good. The sound is more air suction sound rather than fan vibration

[@rss112]

Top video mate! Just what i was looking for! Might of been worth adding that the door for the bathroom should be cut back to allow air flow. But over all great video. I will be installing one of these in the summer.

[@FLOSSYTREADWELL]

BRILLIANT! Thank you!

[@TheDIYGuy1]

You're welcome!

[@simonbeasley989]

I fitted one a few years ago, those fans are brilliant. The bathroom had mould when I bought it as the builders in 2005 fitted a pathetic mains fan in the ceiling nowhere near the shower and bodged the ducting and I swear it couldn't hold a sheet of toilet paper up because I tried it! The Manrose can hold a flattened toilet roll middle up! And instead of motor vibration the main noise is the rather more pleasant whoosh of airflow.

[@TheDIYGuy1]

Absolutely 👍

Great video. It would be nice to have a humidistat option with maybe a wireless humidistat possibly but I suppose this could also be possible with a bit of ingenuity.

[@stuartday1876]

Just used the exact same fan for our bathroom, the performance is amazing. I used solid pipe from the fan out through the gable end, just because I worried about moisture pooling inside a long flexi pipe. I have a small drop on the solid pipe, so it's all downhill to the gable vent.

[@stuartday1876]

P.S. the electrics blow my mind, but luckily I have a brother in law who is a sparks who broke it down into simple instructions😂

Cracking vid mate. Really well installed. One point though that is a safety issue. The wiring between the fan and the 3 pole switch should have a 3 amp fuse installed. I’m not sure why this is as to me it’s a bit pointless but 90% of manufacturers state that it has to be there in the installation guid. Please don’t think I’m being a keyboard warrior as that was a cracking install you did there just a point I picked up that’s all.

Just a tip for the less powerful fans, with the duct work I would always recommend using solid ductwork as opposed to flexi. Better air flow, less resistance, less dirt and bacteria captured over time, Also undercut the door to allow make up air.

[@fredblogges]

How did you get the 4 core from the fan into the back of the fan isolation switch, did you drill up from the back of the back box?

[@VINSCOT5]

Another Informative video🤓🤓🤓

[@TheDIYGuy1]

Glad you think so!

[@MrBinabanana]

Great video, but one little thing worth mentioning is that any electrical requirement in the installation instructions for any accessory need to be adhered to in order for the installation to be compliant with wiring regulations, and most of these shower fans call for 3A fusing on both the permanent and live cores - so the usual 6A MCB for the lighting radial isn't sufficient for compliance. I usually install a separate single backbox next to the isolator with a 2-way grid plate containing two fuse holders fitted with 3A fuses. It's an added expense and arguably overkill, but technically needs to be done in order to make the installation 100% compliant.

[@Participant616]

Hey DIY Guy, would you recommend an inline non return backdraft shutter thing with these Manrose fans, or is it unnecessary?

[@jparky1972]

Nice video and very well explained regarding the wiring. I'm sure I read somewhere that you shouldn't put extractor fan inlets and smoke detectors in the corners of rooms due to how air flows in a room.

[@TheDIYGuy1]

👍 thanks, never had a problem myself with this position but I’d like to hear if anyone has.

[@GretatheEvilGremlin]

Smoke detection should be 1M in from walls where possible and installed flat, as smoke rolls. Extract ventilation is sited more source specific, like over baths/toilets, in front of cooking areas etc.

[@gwarski]

By putting the valve in the corner you do restrict the air flow, however in this scenario the difference would be negligible

[@johnadams1976]

if only those fans could connect to a smart home system.... combined with a humidity sensor in the bathroom... the overrun could then be controlled by the humidity in the room and not just a fixed timer. Great vid as always.

[@TheDIYGuy1]

Great point! Thanks

[@David-dz8jb]

I recently fitted a inline bathroom fan and fused it down to 3a as per manufacturers instructions (this is their get out clause in case of problems) you could make up a multi gang switch plate to fuse both line and switch line together with a three pole isolater but it gets a bit over the top and messy. The best solution I found was fit a smart switch cheap as chips which is linked to Alexa and I find this the very best for complete control over overrun I just ask Alexa to switch on the fan and on it goes for 20 minutes you can alter the settings by just asking Alexa “ turn on fan for xx minutes” and of course you don’t need to have the fan running at all for a trip to the loo at 3am. Probably not the best solution for a enclosed bathroom where I would guess a light linked fan would be required but in my situation this works the best.

[@rehmancricket]

Great video ❤❤

[@TheDIYGuy1]

Thank you!!

[@ef7480]

An observation- the Wago 221 connectors should be used with the Wago 221-4 junction box with the 3 compartments to be maintenance free (although yours is accessible in the loftspace). The Wago box with the 2 compartments at the end like yours is for the 772 and 333 connectors for a maintenance free connection, just in case someone uses the wrong combination and hides it under floorboards or in a wall. The 2 compartment box can be converted to MF with inserts from Wago👍

[@jonron4729]

Hi, thanks for the video, I did not notice you making any comment on the type of fan you must use depending on the zone in the bathroom you have the fan sited.

[@GretatheEvilGremlin]

Zoning is for electrical equipment mounted in a given zone. He's not installed any electrical equipment in a zone.

[@Gixer750pilot]

After securing to a board, i suspended the fan on bungees to stop any noise coming through . Did you not need a back fraught eliminator or is there in already in the fan ?

[@samashevs]

"inshulation" this vid was really helpful thanks!!

[@TheDIYGuy1]

Glad it helped!

[@BALLOOROOM]

Very clear explanations, thanks that's not easy to do. I might be able to fit a soffit vent if I can remove one brick from the top of the 9" solid wall in-between roof rafters otherwise the gap between the roof and wall is too narrow and would constrict the air flow. Are tile vents reliable or problematic, I recall you mentioning a condensation trap is needed, but do tile vents typically leak or cause other issues after some years? The gable end is solid wall so not as easy and would need a long run of ducting which probably would reduce performance. Any advice/recommendations appreciated, I really would like an in-line fan if I can get around the obstacles.

[@TheDIYGuy1]

Thanks. Tile vents are fine if done correctly. But they involve some work! They cause issues if no condensation trap is used otherwise should be fine. Could you solid duct to your gable end? That may be a solution

[@BALLOOROOM]

@@TheDIYGuy1 I should of said the loft is boarded and used for storage so unfortunately not a straight run of ducting it would need to go round the perimeter so at least two 90 degree bends and at least 9 metres long as it's the other side of the house. I'm guessing the fan would struggle and I'd need to wrap the solid ducting to insulate it.

[@qkayani]

Would having the vent above the shower not cause a cold draft coming down when showering , say if you don't put the lights on in winter? Would being slightly further from where you stand be better?

Good job 👍 need to install one myself. i always wonder why do i have to turn on the lights for the extractor fan to spin. Is it not better just to have another swich for it and just turn on the fan with no light after the shower is done? Is it something to do with building regulations?

[@LeiChat]

I would like to use a smart switch/relay to control the fan based on a humidity sensor, rather than having the switched live from the light switch. Do building regs require the isolator power to come from the light switch?

[@surya2089]

Hi can we use some other things for ducting ?

[@delspark]

i felt the pain in the loft😓, i would of personally used a click mode fan isolator with fuse to meet the 3amp as per instructions and use this for the downlights too, normally mount the fan on the cheap rubber matt to lessen the noise. And don't forget RCD for cables in walls 👍

[@steve6375]

I use medium hard rubber spacer standoffs to mount the fan motor. It makes a massive difference to the noise because the board you screw it on acts as a sound board and amplifies the vibration. Easily available from Amazon, etc. Don't know why Manrose don't supply them in the first place!

[@Morbidia]

Nice one! Out of interest how did you get the cable from the box you cut in up into the loft space?

There’s an airing cupboard behind the back box, drilled through into there and then up into the loft space. Alternatively I’d of just chased the wall out up to the ceiling.

Hi Cameron great video as always, was wondering if you wanted to use the extractor without the light on, would a fused spur powered from the ring main be acceptable?

[@MuckSpreader99]

Instead of screwing fan onto board, place onto a pillow made of loft insulation and a plastic bag. This will provide sound and vibration isolation. Another way, given room and dependant on local conditions, is place the vent on the facia. This provides a straight through hose connection, unlike a soffit vent. Either way, make sure you drill between the rafters/trusses otherwise you'll be drilling the vent to find it blocked!

The Manrose MF100T instructions state it must be fitted to a circuit with a 3A fuse. 18th edition states manufacturer's instructions are taken into account for electrical installation. I use a double pole fused spur as the isolator with a 3A fuse fitted and a double pole light switch so the lighting circuit and extractor circuit are switched separately when installing these.

Hi mate, I wonder if you can help me, I have a 2 way switch controlling one light on my hall way, I want to remove the second switch so the light is just controlled by the one switch, if I remove the linking cable am I right in thinking I will need to rewire the other switch so the light still works? Thanks mate

[@narrowboatlongpod4176]

The way 2-way light circuits usually work (in the UK) is by linking L1-L1, L2-L2 and C-C in both switches and putting the two wires from the ceiling rose across L1 and L2 in one of the switches. If the switch you want to keep is the one with the ceiling rose connection then you can remove the link cable and move one of the ceiling rose wires to C. You may have the neutral in the switch box if you don't have ceiling roses but it should still have the connection to L1/L2 after removing the link cable and move one to C.

[@banzaiman1]

What speed you got your fan set to? I've got the same fan and it's only on slow but it's an absolute beast of a fan
