Nice job Mark, just seen this video. I used to work for a company that carried out service calls for Nuaire and other manufacturers. We used to be called out to mainly service, but sometimes if there was an issue we would inspect it to see whether it was an installation error or a fault with the unit when in warranty. Nuaire would replace if necessary, but you would be surprised how many install errors we would see😂😂. Nice to see you have fixed the outlet to wood above the ceiling as opposed to fixing to the larves, we always cringe when we see these types of old ceilings - you manage to cut the hole well 👌

Thanks Andy. Yeah nightmare on those old ceilings.

[@davidbrittain3212]

@@electrician247 HI Mark. Great vid many thanks. I'm thinking of fitting one of these but how do you screw the inlet securely to a plasterboard ceiling? I guess you put a hardboard specer ro something on the loft side hole and screw into that, but how is that fixed in place? Ta!

[@scotthenry3401]

With a hardboard, or ply or whatever on the loft side would form a clamp squashing the plasterboard between the outlet and the hardboard, you could use a sealant like a flexible caulk if you wanted . That will be more than sufficient to hold fast under any normal operating stress which is miniscule.

Insulation causes the issue. My homes cavity and loft insulated. Homes don’t breath anymore. I’ve a no window bathroom with an expel air that runs ten minutes per go once lights off. My windows are soaking. I’d never heard of these until yesterday. Very appealing. Il fit myself. Cheers

[@electrician247]

Trickle vents, under cut internal doors, seal all penetrations to loft such as spot lights and loft hatch, extractors to all bathrooms/WC and kitchen. Ideally continuous flow variants. Alongside a PIV it will work a charm.

[@MrSmid888]

Never seen one in a loft. 🤷🏻‍♂️ A guy on a KZbin video suggested one. I’ve no spotlights, I can seal the loft hatch no issue. Il be getting new windows next year but I fear they’ll do nothing, the issues in the air. Cheers

[@thepaintedsock]

Really useful video thankyou. Just curious if you think this would be suitable in an area of a lot of chimneys and wood burners, including my own which is pushing out some polluting pm2.5, that it might push that back into the house as the loft contains the chimney going out the house?

You would need a survey to determine the chimney was in tact. It should not be leaking into the loft space

Hi Mark, great video. Can i just as a quick sparky question here. I'm not a qualified electrician however i'm more than proficient in electrics and general DIY. I've got a double socket in the loft space currently powering our cctv setup and wondered if i can just spur off this socket into the 1amp fused spur included in the kit. Alternativelyi was given the info from the manufacturer that i could just bypass the fuse spur and stick a 3 pin plug on it and just plug it in. What are your thoughts?

[@factorsixty]

Hi, thanks for the great video. I'm just wondering if when you first turn it on and it chooses the temperature mode should you choose the mode yourself following the instructions or let it do it itself automatically?

[@electrician247]

It defaults to mode 1 which is generally what's needed. If you want a different mode you will need to select. Other features such as speed and heater are on the grill plate controls.

[@designer23t]

Very informative video. I am looking at having one of these installed, but the house is a semi with the party wall in loft not fully sealed. Would this be an issue, and would a wall mounted version be a solution? Thanks in advance!

I can't say with that model but with the Nuaire drimaster which has similar "Top hat" filters where it has the humidity sensor when its flashing red the filters need changing. When the filters are discoloured and dark they aren't doing their job so its best to change them regularly as per manufacturers recommendations

Every 3 to 5 years or so.

Hi Mark thanks for the useful video! We’re thinking of getting one but our loft has been converted into a spare room. Will it be effective if we put it in the eaves? Cheers

So long as they have good ventilation in the eaves and they are well sealed from the bedroom itself it will work.

[@d.w.evans1182]

Hi, I see there’s a three storey version for three storey buildings but its nearly double the price of the standard version, is it absolutely necessary to get the 3storey version? Apologies, but I’m clueless when it comes to building regulations.

[@electrician247]

Yes if you want it to work you will need the correct model. Standard version would still have an impact but wouldn't be as good.

[@fournierdon2172]

Around the 17:00 mark it looks like the suspension chord might be in contact with the horizontal roof timber. Could that not be a potential chaff risk leading to the unit falling on to the ceiling? Am presently considering one of these for my own house so am keen to learn as much as I can before I take the plunge. Not shown but I presume there must be some sort of cage inside the filters to stop them collapsing.

[@electrician247]

Hi mate, cord is hanging freely but it's strong stuff. You can get the mount kit and fit on timber base if you wish. Just make sure to get the rubber boots which reduce noise/vibration. The filters have a steel hoop in the ends of them. Very sturdy once into position. Thanks for watching!

It only takes the chill off rather than heating. Perhaps the heater has failed if its really cold.

Would you use a lighting feed to go to the fused spur (3a). Couldn’t clearly see in the video

If you have this unit you should see an orange 'on' light behind the disc. If you look at 6.58 you will see the light next to the blue switch. In darkness, if you stand about a metre away from it you should see an orange glow. Just remember to look at it from all four sides. You should also be able to hear it, although it is quite quiet.

Hello, can you please advise with the cost of electricity of late, how much it would take to run the system with the heater. I'm wanting to purchase but need to make sure I'm purchasing the correct one on cost.

[@electrician247]

Not especially expensive tbh. Even the heated models runs on a very low energy consumption. The heater pulses on and off rather than continuously. Costs vary massively based on tariff. But it's negligible and can actually reduce heating costs.

[@ifyougetstucklookitup237]

Thank you for the informative video.

[@latifnajimi3436]

Hi, can in install it on the bathroom ceiling?

[@paulbayliss4372]

I'm unsure on wheather to get the heat or non heat version, can the heater still be wired separately or turned off on the newer models?

[@electrician247]

I would advise a heated version and to leave it on and running. You can set the temp for it on the diffuser. Even on max its not permanently on and very low cost to run. On min it would essentially be off 99% of the time.

[@oxxSTEVExxo]

Mark, Would it be a really bad idea to cut the hole from above in the loft? I can get easy access to the upper side of the plaster board and take my time cutting from above rather than struggling on a ladder or step from below.

[@electrician247]

Never tried it to offer comment lol. But I would suspect you run a greater risk of cracking the plaster and damaging the ceiling. Go steady if you do it.

[@Jaxrus1]

That's what I did. I marked it out, drilled a hole big enough to put a saw blade through and then cut it out by hand. Still scary doing it though 😂

[@Frankiedoodle1941]

Hi Mark, great video from the layman point of view, 2 things I would like to pick Your brain about , 1, whats a ballpark price to fit the unit itself into a 3 bedroom bungalow with a large high loft, & 2 a rough idea of the price of a Spark to do the electrical side of the job, .............Regards

[@electrician247]

You would need to ask a local contractor and have a discussion. Lots of variables.

[@davesmith2910]

Nice video. Thanks. You mention ventilation of loft. How can I tell if the loft is sufficiently ventilated? Don’t want to make my situation with condensation worse! Cheers

[@electrician247]

Hi David. You need to see if the soffits are vented for example, if you have roof vents allowing airflow and air bricks. Basically a good flow/circulation of air within the loft. Also that your loft hatch is well sealed and any spot lights etc. We want airflow but not from within the house if that makes sense. Otherwise that moist air will simply be blown back into the property. Most loft spaces are naturally well ventilated. It's more an issue if any partial loft conversion has taken place or extensive insulation that has removed that airflow. Hope that helps. Mark

[@roberthaney4158]

Just to ask, do you install in the westmidlands and if so what would the cost be for the unit in this video.

[@electrician247]

No they dont blow out hot air. On the max setting they add around 8C-12C to the air temp in the loft. Essentially taking the chill off. Perhaps they forgot to attached the heater control wire as it shouldnt be freezing. Have mine on the landing and dont notice any cold through winter. You could try slowing the speed down as well.

[@martyn19760]

Hi there Many thanks for taking the time to make the video and it has cleared some questions for me, great stuff. I'm looking into getting one of these. I live in a grade 2 thatched cottage. Not sure if there's vents but there most certainly is a draught from somewhere as the cobwebs are moving about. There is also a previous owner installed extractor vent from the kitchen to the loft (gets used very rarely and I'm assuming Nuair say don't use if the case as I'm assuming it would re-introduce smells/moisture into the house if both on). Probably due to laziness not bothering with heritage planning permission to vent to outside. If I got the wall control I could switch PIV off whist extractor vent being used and an amount of time after for now. Would you advise getting one of these and I can afford the heated one incase with the details I've mentioned? Are the heated ones very expensive to run? My loft feels warm a lot. Many thanks

[@electrician247]

Hi Martyn, thanks for the kind comment. Firstly I would get the extractor correctly vented. It will be causing unseen damage to timbers and the thatch. Even if the PIV isn't running when the extractor is it will still raise the humidity in the loft for a prolonged period. I wouldn't advise running it this way. 100% heated versions are better but worth checking in terms of the thatched roof and risk of fire. I would perhaps consider enclosing the vent plate in fire board perhaps. One for an installer to carefully consider based on site conditions! Thanks.

[@electrician247]

PS they are not expensive to run. The heating element pulses on and off to reduce energy consumption. It doesn't produce hot air. More takes the chill off by raising the loft air temp by a max of 8-12C (it's adjustable)

[@davidellis5964]

I have fitted quiet a few of these, some hanging up and some on a joists. The only problem is fitted the ducting ! its a tight fit. I fit mine before taking the unit into the loft. The anti vibration kit unit isn't really require just fit some rubber grommets under the timber before screwing down. Also some lofts cannot take the unit due to poor ventilation within the loft. I have installed soffit or ridge vents to increase the air-flow. There is another unit called a Remcon which hasn't got a heater element, much easier to install.

[@electrician247]

Hi David. Yes good loft ventilation is critical. Also 100% on getting the duct on. Can be a wrestle at times! You can get these without heaters also. Thanks for watching

How long you had it on? Do you have bathroom/kitchen extractors? Undercut any tight fitting doors? Trickle vents to windows? Insulated roof? Loft sealed from the house properly aka hatch and spot lights? Has good ventilation to outside in the loft? They do work so something isnt quite right and can be solved! Unless you have an active leak or damp entering the property from somewhere? Sometimes they can take several weeks for the effect to be noticed if the building is especially damp. Hope that helps.

This system relies on the air in the attic being warmer but the whole point of loft insulation is to prevent heat going to the attic? Too many questions. This is the next cavity wall insulation problem.

That's not true. Generally the loft has less humidity as its effectively outside if the survey is done correctly and it's suitably ventilated. The air temperature isn't that important with the heated models. Of course it will consume more energy to warm the air a little but not a huge expense to cure the destructive damage of mould and condensation. The heating is difficult to get your head around but our bills dropped. Humid air requires more energy to heat it. So as the humidity drops due to the injection of fresh air thus the heating has to work less hard to raise the temperature. This is not new technology. Its well established and proven. It does not bridge wall cavities and allow ingress like cavity wall insulation. That's a silly comparison to make. Hope the info helps.

@@electrician247 How do you find it works in very wet weeks for autumn / winter. The the outside humidity should be 90% + outside ? Arn't we just replacing warm humid air with colder humid air at that point ?

Can you install my system for me?

Cheers Scott, work an absolute treat for condensation and mould. Brilliant in new build especially.
