Just fitted same unit but cored through wall, fitted manrose internal fit outlet with back draft shutter and insulated hose for condense free operation. The difference between those little fans and the 345 cubic metre per hour ones is great. Did the spur job first time so just wire swap over as spur and fan all laid out on a piece of 20 mm plywood. Its only took me about 4 years to do as my loft is only 4 ft high in the middle and the bathroom is on the side of house so worked in 2ft triangle, hence the long term thinking about it 😁.

[@alsanova]

Wow loft insulation was so bad which is also part of the problem. Glad you help insulating it as well, hope that will help. 👍

[@alanpark9670]

Top tip!!! Extract fans work better sucking rather than blowing....so always install fan as close to the external vent as possible. I will give you that one for nowt!👍

[@danmetcalf3866]

That's how mine is done 👌😉

[@alex1975uk]

I’ve got insulated ducting in and out, should I attempt to insulate the body of the pump? Any chance the moisture can condense whilst going through the pump in a cold loft?

Get yourself a couple of 3m scaffold planks. Cut one in half (2 x 1.5m, and the second into quarters (4 x 0.75m). You will be amazed how useful they are when working in lofts.

[@martin54123]

I always bring the fused switch down onto the wall outside the bathroom (normally above the door frame) so it's accessible, personal preference and means the fan can easily be isolated in case of a problem. Saves climbing into the loft just to change a fuse too!

[@beardedsparks2825]

If there's a problem with the fan, you've still got to go in the loft. It makes no difference where you place the fused connection unit.

[@martin54123]

@@beardedsparks2825 Yes agreed, but if the fuse pops for any reason at least the customer doesn't have to crawl up into the loft.

[@beardedsparks2825]

If it pops there's a problem and the fuse will blow again. Someone will still have to go up into the loft regardless. Also, the switch is to isolate the fan, you want that isolation device close to the item it isolates. You don't want someone switching it on when you're in the loft working on it.

[@martin54123]

Personally I always isolate with Wago's when working away from isolator. My original post was my personal preference anyway, everyone had their own way of doing things.

[@Tokaisho1]

@@martin54123 The fuse is ultimately there to prevent a fire in the event of equipment or cable failure, it is not something that should ever need to be replaced and if it does you need to go into the loft anyway to repair or replace the fan. Manrose however say that if the fan is on a 6A lighting RCD/RCBO the 3A fuse is not necessary

[@mbplove]

FFP3 mask when working around loft insulation and you should use insulated ducting in a loft like that to minimise condensation, a lot of inline extractors require condensation traps to be fitted now.

[@DaddyBear3000]

The lack of insulation was half of the problem. Moist air meets cold surface = condensation. Had this on a single skin wall in a bedroom. Warm room with a dehumidifier on and reasonable ventilation. Soaking wet wall covered in mould. Insulation and boarding over was the only way to stop it (after killing off the mould and drying out with fan heaters).

[@loosecannon5813]

Excellent point about the loft insulation being removed.

[@dancrawford2690]

Karl I agree 100% the lack of insulation is most of the problem, and I also noticed they are drying out towels on the radiators

[@kingspunkbubble]

We had a mold patch that kept appearing in our bathroom. When I got up in the loft to take a look the insulation had been removed directly above. Funny enough it looked like it had been done by whoever installed the extractor.

[@zstation64]

[@chrisparker3331]

Just a question about positioning the exhaust vent. If the vent is over the window won't you just draw the same, damp air back in to the bathroom? (I can't actually see the vents in the video due to the contrast but in the preamble you said that's where you'll fit it).

[@flamingskoda]

They should paint the ceiling with Crown Trade Steracryl mould inhibiting paint. I use it in all the mouldy tenancies I decorate and it works well.

[@AzH1988UK]

I've just fitted my fan , my ducting runs up I've pulled it tight as you suggest , is it ok to have the fan mounted horizontally but the exhaust going upwards?

[@zeea6507]

Please advice me, I had an inline extractor fan fitted and a roof tile vent but he has connected the inline fan to a normal extractor fan. So my bathroom has a celling extractor fan connected to an inline one in the roof. Is this ok or should he have just used a vent in the bathroom?

[@xxxyyy9544]

Just about to install a Manrose MF100T extractor fan. I thought venting through a soffit was bad due to the damp hot air being sucked back into the loft via the soffit vents creating dampness in the loft. So the options are through a roof tile vent kit (which I will not attempt) or core drill 117mm hole through the gable end wall. Enjoy your videos but am uncertain if soffit venting is ok, certainly easier.

[@daibonehead]

I love watching someone that knows what they're doing. That said, I know nothing. But top work. I do have a question though. Do you need insulated pipe? Or is putting the loft insulation in top of it enough?

[@lewis94uk]

Those manrose fans are very good!

[@johnhoward2104]

Some nice little jobs. I avoid a vent being near a door or window that opens into the room from which air is being extracted because the extracted air could be sucked back into the room; I don't have any stats on it but seems a reasonable precaution. And they say that rigid ducting is preferable to flexible with in-line fans, yet provide flexible in the kit - go figure. What did you use to cut the holes through the plastic soffit? And doing these little 'oh, can you just do that for me...' is part of self employment I'm afraid, we've all been there, just have to grin and bear it and think of good karma.

[@ZanderKaneUK]

Anyone know the reg's or at least the pro way to do it, on ducting on the cold side (loft) of the house? Always thought you "should" use that insulated laminated silver ducting? Wouldn't the hot vapour in the duct and cold of loft cause water to sit in the bottom of the ducting?

[@Clip7heApex]

Many times seen those flexy vent pipes full of water from condensation building up, as the loft, and therefore the inside surface of the pipe is cold. Trying to vent warm damp air out results in the condensation building up and causing the pipe to sag under the weight of the water. Better to use insulated vent pipe as it prevents this and makes it much quieter too.

[@andyhawkes3335]

We use envirovent fans expensive but never let us down

Nick, thanks for another great video, very detailed. You look good in it too. I was just watching Artisan Electrics thing on monetisation (youtube) and it struck me how many people - like me - have replaced their old chasing set ups with the Metabo stuff you showcased, all because of your video. I certainly did and I hadn't budgeted for tooling to the end of my accounting period but did it anyway. If you'd linked it through to a wholesaler with a decent discount on that stuff you'd have got yourself a fair few pennies with a 5 percent commission. I don't think you did have a link did you on that? Have a good week.

By the look of the plumbing there's been a lot of DIY bodgery going on there. Ptfe does not belong on compression joins

Not required but you often see it used, I use it too. As long as it is wrapped around the olive and not the thread, i.e. where the joint is actually being made, no harm done.

Interesting that you use the black as the neutral (sleeved blue) and grey as switched live (sleeved brown) Nothing wrong with it but I’ve always done it black as switched live and grey as neutral. Doesn’t matter as long as you sleeve them I guess. I always use white duct tape to attach the ducting to the fan, gives a better hold!

Is the 5 or 6amp breaker too high for a fan ? Not got a fuse fitted to mine 😯

[@westinthewest]

The fan is a fixed load so you're probably fine. Regulation 433.3.1 says that you don't need to worry about overload. You just need to make sure that the MCB will provide fault protection. You could very likely connect your fan using 1mm cable directly into a 32A circuit. I did something similar last year for a new wall light. I checked the spec on the 32A Hager MCB and confirmed on the minor works certificate that it would disconnect in good time if a short circuit occurred. You might find that even a 50A breaker would be fine. It was in Amd 3 of the 17th Edition when following manufacturers' instructions was changed so that they only had to be 'taken into account'. The fused spur is usually unnecessary and can be omitted.

[@flipflop595]

@@westinthewest Thanks for your reply. It's suppled by a 5amp breaker on the lighting circuit an old 1987 MEN braker unit tho. Installed the fan myself, (I repair domestic applyiances for a living) and an other thing how would you go about putting a fused spir on a fan with a timer eg two lives? Can't see how that would work ??? 😀

[@westinthewest]

@@flipflop595 The 5A breaker is good for overload and fault disconnection. 1mm cable will handle up to 13A so you don't need additional fusing from a BS1362 fuse e.g. 3A, 5A or 13A. Interesting question about the timer fan and the two lives. You'd have to fit two fuses but then if there were a fault, only one of them would pop and there would still be a live connection in the other one. It's possible that manufacturers don't mention fused spurs (FCUs) for their timer fans. Have you seen the fused spur mentioned in the installation instructions?

[@flipflop595]

@@westinthewest There was no mention of additional fusing in the instructions for the fan . I got it from ebay, the fan itself is an inline one like the ones you installed but centrafugal type one "fan blade".

Worst case scenario is that you derate by 0.5, that means cable will only carry half it's original rating. 1.0mm t&e will carry 16A clipped in free air, derate by 0.5, that's 8A it will carry. Most lighting circuits are on a 6A circuit. Where's the problem?
