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.

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... 👍👍

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

@dougle03 6 күн бұрын

@@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.

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.

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.

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.

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.

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👍

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 16 күн бұрын

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 16 күн бұрын

@@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.

@MrBinabanana 11 күн бұрын

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.

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.

Such wiring has to be carried out by a qualified electrician under Part P of the Building Regulations. I never specify that the fan is energised by the light switch simply because you cannot guarantee that the bathroom or toilet user will turn the light on. By far the best option is to install a PIR detector to switch the fan, this guarantees that the fan is switched on whenever the room is occupied. Bathrooms invariably contain a WC and the smells need to be vented, you can expect that at night the light will not be switched on if the person has gone to the loo in the middle of the night. In addition, fan ventilation as shown simply dumps the warm moist air outside but now we have the opportunity to extract the heat in that moist air and send it back to the room. These heat recovery fan units are more expensive but pay for the premium quickly in the energy saving. I would strongly suggest that the fan unit is mounted on AV dampers as the form of construction shown will act like a sounding board and be noticeable in the room below - I have direct experience of this.

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!

A guy who's hot even when he's not in a 65 degree attic! 😉 As an American, I find the differences in electrical systems fascinating. Both have their benefits and drawbacks, but I don't understand why electric in bathrooms is so restrictive for you all. GFI has been a thing for a long, long time, and there doesn't seem to be any issue with outdoor switches and sockets, which anyone can try to use while dripping wet in the pouring rain.

@jpjapers 16 күн бұрын

In the UK you can have sockets in bathrooms but they have to be I believe minimum 10ft away from a water supply. Most of our houses don't have bathrooms so large that would allow for a socket so we just dont have them.

Voltage used in the uk is higher than the US this leads to many restrictions when it comes to wet areas.

@marcberm 15 күн бұрын

@@abdoaiman I don't really buy this either, though. Although our frequency is higher in the US (60 vs. 50), our power system is still nominally 240 volts. Because we use split phase, the bulk of power is consumed in 120 volt applications, but we still have plenty of 240 volt loads and a system operating at that potential. Also, something that confounds us here (in America), is that for all the fear and restriction around using electricity in proximity to wet humans in a bathroom, you all have no problems putting a screamingly powerful electric resistance heater IN the water stream of the shower! 🤣

can I do this as a diyer under the P certification, or do I need an electrician? I'm not totally sure because it is a bathroom, and not sure if the new wiring is considered as new circuit. Excellent video anyway, I just bought my first home, and I suscribed to your channel as it is really useful

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?

Did I not need the 6A fuse way? I did this with virtually identical but different make fan. I thought you had to put a 6a fuse on the fan. I struggled as DIY to get my head past the switch live not been 6A fused so I spurred off the the loop and put the light and fan through the 6A fuse way. My over-run fixed at about 25 mins, would look at the manrose next time I think 10 minutes would be better.

@delspark 13 күн бұрын

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 👍

So with your wiring you have to put the light on to start the fan? In the summer months when there’s plenty of natural light I’d want to just have the fan on without the lights

@bertbox69 6 күн бұрын

You can have a seperate on off switch with string, next to the bathroom light switch to switch it on manually instead, or a fused on off switch high up but must he outside the bathroom. Some fans have timer anyway so it wouldn't matter if you switched it of manually, you still get the benefit

@steve6375 12 күн бұрын

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!
