Excellent as usual Mark 👌
Thanks Mark, just installed ours today by watching your video. Now to see if it works!
Just come across your channel, great video, had a piv unit with a dual outlet fitted around a year go but a different brand (envirovent), had no idea about the smoke alarm positioning as one of my outlets is placed with in 500mm of a smoke alarm and the other 400mm off a heat alarm with no dampers installed also was installed by the company that sells them, guess I will be on the phone tomorrow, but again great video and great information 👍
Double check, because if there was no way to keep it away from the smoke alarms (i.e. not enough free space on the ceilings), they should have installed the baffles/deflectors to direct the air flow away from the detectors and you should be ok 👍🏽
Great content as usual, appreciate the effort on all your videos. The ladders you used to access the loft, were they the Little Giant Dark Horse ones? Thanks
Thanks mate. Ladders were off amazon. Cheaper version than little giant but they are decent steps all the same!
If you want a really neat job when fitting anything odd shaped into plasterboard the drywall routers are brilliant for it if you don't have a steady hand with the buzzsaw. Lovely showcase of an installation and how to configure and maintain one.
Yes they are epic tools. I am still kicking myself as I had a dewalt one but lost it..... loved it but refuse to pay again which is kinda silly when it's my fault I lost it 🤣
@@electrician247 I know all too well how that feels, just wait til you see them on offer and grab it. Occasionally see them drop below 100 on screwfix etc but always sell out fast.
Great video. Can you tell me what a herm is?
Can I get a link to the unit you recommend please? Our windows are like a water park in the morning. Thanks!
My dad told me about these a few years ago and have always thought about installing one at home myself… seem like really good products
We have installed lots over the years. I have them in my home and family members homes. They work. But get the heated version and if budget allows the Nox version also.
@@electrician247 yeah definitely… I’ve thought about using these instead of in-line fans in bathrooms but I guess you should use them in conjunction with them rather than instead of…
@@hackwoodelectrical for sure mate. In conjunction. Important to have back ground ventilation and extract moist air when you can.
@@electrician247 What does the Nox version mean?
@@ciaranhughes8705 has the filters that clean the air of contamination www.nuaire.co.uk/product-list-page/drimaster-eco-range look at the nox model on the drop down tab on this page.
Fantastic video Mark, much more informative than those supplied by the manufacturer. I got one of those, but unfortunately it seem to be faulty, after wiring the power doesn't reach the unit, no LED lights go on, the electrician says 240 gets to the heater board but nothing comes out, I'm based in Spain and the manufacturer doesn't take any responsibility for more likely faulty device, have you ever came across that, any advice would be much appreciated, I'm desperate, defo won't get my money back and I don't want to risk getting a new device! Thanks
Have all the communication leads been attached? There is a short one between the heater and the control board that fits in the grill plate. This often gets missed. Also the comms lead which is longer back to the PIV itself. Hope that helps. Mark
Great video Mark, it would be great if you could show the installation of a flatmaster 2000 or similar in flats with no loft access seems to be a lack of videos on TH-cam about them. 👍
Great suggestion!
Really informative video! I've trawled through the comments, so forgive me if I'm repeating a previous question, but can you tap into a lighting circuit with this (heater) unit, or does it require 2.5mm cable? In my loft there's plenty of lighting cable but no ring main, like a lot of lofts I guess...Much appreciated !
Hi mate. These are fused down via a supplied 1A FCU so can be wired from a lighting circuit. In some cases that's better as it's easier to know when the power to the piv goes down and stops tennants turning it off.
Consumption is small so similar to having an extractor fan on the lighting circuit.
Hi Mark. Excellent video on the installation of the Nuaire PIV, thank you.
Have you compared the Nuaire Drymaster to the Vent-Axia model?
I have and we choose to only install the nuaire.
@@electrician247 is there any particular reason why you dont go for vent-axia? I have seen both of them on Amazon and the price difference is quite a bit. Great video very informative
@@DickTheDastardly we did try them but had some early failures. Nuaire is better quality imho and you get what you pay for.
Does a PIV unit chill your house more in winter? Surely it will blow in cooler air as well as force the warmer central heated air out. If you set the heating element to a comfortable home temperature (somewhere around 19-21°c) would this cost a lot to run?
It takes some figuring out in your own mind. I had my doubts but it actually helps keep the heat in your house. By keeping the warm air from rising.
That said the heater is generally set to 12C and pulses on/off to take the chill off and allow for more bearable airflow mixing in landing spaces were it can get cold under the vent outlet with unheated models.
Running costs are minimal even at current prices.
What about getting a feed of a lighting circuit if the consumer board is full
Nice video, thanks . Just wondering does the machine blow dust particles from the artic back in the house... i saw filter but i would be worried fiberglass particles from attic insulation going back into the house....
Filters prevent that. Helps remove allergens from the air. Cam even get advanced filters for even finer filtering.
Informative video however I would be interested to understand how the system conforms with Revised Part F - Ventilation & Part O - Overheating which are both due out in June 2022. Also what is the average watts per year the heater will use? Airflow of the unit is dictated by the nearest wall positions to the outlets. If higher airflow is required, baffles should be used to stop 'dust build up on wall surfaces'. The unit you describe has 'high quality' filters fitted. So where is the dust coming from?
That's one for the manufacturers to answer in terms of compliance with new regs. I am sure they will be ahead of that curve.
The dust is a pretty easy one. It's naturally circulating in the air all the time. The pressure on the air if close to a wall surface does tend to result in staining/dust collection. Makes sense really if you imagine the dust debris that builds up on trickle vents, extractors, doorways. This is similar. A source of air aimed at one spot will deposit dust that is just present in the air rather than injected from the loft.
You can even get the Nox filters for Improved filtration out of the loft but these buildups still occur.
Thanks
A few houses i work in have the older Nuaire Drimaster 2000 for ventilation.
I do find the filters get really black as the filters need replacing every so often which doesn't get done on maintenance once the product is installed
Yep a very common problem. Every 5 years. You used to be able to run them through the washing machine but that's not recommended now!
Great video, just one question, is okay to spur off the 1.5mm lighting circuit or does it need to be from the 2.5mm 13amp ?
Did you discover the answer? I was wondering this too and can't find the answer anywhere...
@@sufc43 I didn’t receive a reply but I spoke to customer services at Nuaire and they said it was okay to spur from the lighting circuit, best ring them direct just to confirm though.
@@Family.Channel Thanks for the reply.
@@sufc43 I have the same question here and wanted to know if you installed a PIV in the loft through the 1.5mm lighting circuit?
Thanks
@@newhomediy Yes, switched fused connection unit, 3mm fuse, all working lovely! The OP was kind enough to answer my question on a different video, so I am grateful to him for the info.
Hi, great video! Question... We don't have trickle vents on our windows. How does the air pushed in from the PIV unit then push out the humid air? Do you need to leave a window open slightly?
Just a like and no answer? 😂
@@bergzy7 were getting piv installed soon, fitter saying if got kitchen or bathroom ventilation be fine.
We've got no trickle vents as window company didn't fit them like I asked.
He also said you could have a vent size of tennis ball on ceiling each bedroom.
@@adrianflake8273 We do have an extractor fan in kitchen and bathroom so hopefully should be ok. Let me know what you think of the unit... I'm thinking of buying one in Jan
@@bergzy7 get mine 29th December so let you know.
Hopefully get rid of bit of condensation at bottom of windows without using dehumidifier.
@@bergzy7 ain't going ahead with it now.
Got them to send name of exactly which piv and which bathroom fan was getting.
40 pound fan which was discounted at £200fitted.
And the piv wasn't one I was expecting and was £300 online wanting £695inc fitting.
So not paying someone £500to fit for couple hours work.
Hi. I'm going through same issue in my house and builder have installed 2 bricks in concern room. I was wondering if you tried air vents before installing the system and how's your system doing now?
We have trickle vents in Windows etc. This worked a charm
Great video👍 and as one other says ‘much more informative than what the manufacturer provides’
Just installed mine, electrician wired it in and low &behold…… there’s not a kick out of it. It’s flashing ‘F’ which apparently means it needs replacing. To say I’m livid is an understatement!!
Waited a month for delivery, I told the misses this unit is gonna be the business and now My wife is giving off that we’ve spent the guts of 600 purchasing and getting it installed and all we have to show for it is a whole in the ceiling.
I’m just waiting for 9am so I get on to the supplier. Not happy!! And the trouble is if the supplier offers a replacement I’m dubious as to what faith I now have in it
One thing to check is all the comms cables are correctly installed. The long one between the PIV and the wiring loom and the shorter one in the heater/outlet plate. If they are not properly in place it will throw an F fault. Hope that helps.
@@electrician247 Top man Mark, I did check that last night, but i intend doing a full check on everything later when I’m home. I hope it is something as simple as that, if so I’d be delighted.
Appreciate it cheers 🍻
@@marklynch4493 yes, sometimes they can be not sat down quite right or the wrong way around. So worth a check over.
Just off the phone with the supplier and they’re awaiting a manufacturer response which can take 7-10days!!! As standard, which is shockingly ridiculous!!
apparently there is a stock shortage due to a delay with sourcing a particular component that is holding up manufacturing and it’ll be the end of February before there will be any sign of a replacement. So I’m £500 quid down with a hole in my ceiling and a wife who doesn’t fully appreciate the situation!!

Would you not recommend the unheated version then?
I want to get one but don't want it to cost a fortune to run throughout the year especially with electricity prices at the moment being so high.
Definitely wouldn't recommend it at all. The heated versions don't cost that much more to run. The elements are pulsed on/off rather than continuing to run. Bit more expensive of course but much more effective and saves on heating costs over all. Unbearable to have them on without a heater in the winter imo.
@@electrician247 Glad you said that before I froze my house!
How much to install one of these
I'm looking at getting one off these. My house is a solid wall I've just had some external wall insulation done and i think one of these would help the air around my house. Where about are you please? I'm just thinking about getting a price thank you 👍🏻
We are based in East Yorkshire
Hi, looking at getting one of these installed in our 3 bed cottage as really struggling with condensation upstairs and it’s creating mould areas around windows. What areas do you cover, we are Bury way?
We can come to Bury but it's outside our normal work area. Prices are typically around £1100 with the VAT supplied and installed.
Drop an enquiry over to mark@powersonic.co it is just .Co on the end
Do these help during muggy summer days drawing cooler fresher air in in the evenings?
I wouldn't say so tbh. They do shut down in high loft temps but won't really impact in that way. Mine doesn't anyway!
Fans and AC the best way to combat that
Do you need an outlet duct through your roof? Where does the air go that is drawn up out of the house?
I think I answered this on another video with yourself lol. But for those following here. It injects air rather than draws it out. Which is why you need a well ventilated loft space or to use the flatmaster version to duct the air in from outside.
We were looking at this as an alternative to trickle vents in the windows. As buying windows with trickle vents completely negates the sound proofing of windows which is a big reason why were buying new windows in the first place, due to noisy neighbours.
We were told by a local window company to get one of these so you don't have to have the trickle vents. Is this not the case?
Yes and no... basically you need natural points if extraction for air. That can be extractors etc. Trickle vents work best imho
@@electrician247 that's just a no go for us. We're a family of autistics and need the sound proof. Can you suggest anything else?
@@Thorocious mechanical whole home ventilation then. This removes and injects air to the house
@@electrician247 have looked into that.. This is an old home and would cost a small fortune to get that installed. Was really hoping the PIV unit would be enough.
Guess we're just going to have to block up these massive holes on our brand new windows.
Any idea who we should complain to about these new regulations? If we all make enough of a fuss about it I guess things could change. My local window fitting companies are absolutely livid about this change.
How loud are they? Can you hear them or is there a constant hum when installed?
At low speeds almost silent. Faster speeds it can be heard if your close enough but still very very quiet.
Always suspend them rather than fix down. Even with the rubber buffers it makes more noise when fixed down.
Hi Mark, I've been told I require 3 fans (Downstairs Utility room, W//C (Next door to downstairs utility room and upstairs Bathroom) This would be fitted in the loft and comes out on the upstairs landing? Does this sound correct to you? I'm unsure how this would work supplying to two fans downstairs and one fan upstairs? How would this work in the landing?
Sounds like you have mechanical whole home ventilation going in? That is different to a basic PIV.
@@electrician247 I have asked them and it's this model. Lo-Carbon
PoziDry Pro by the company Vent-Axia?
They were installed in Bradford council houses about 15 years ago, I don't know anyone who still uses them
Older models without heaters were less than tolerable. You can install these in a locked mode for rental properties but that never sits well with me when it's occupiers paying to run them.
@mark I get bad water build up on my downstairs sunroom windows. Would one of these help. Can you give me a average price it would cost to get one installed. I have a socket outlet in roofspace so you could spur of that.
Hi Ciaran, it would help with that. Where abouts are you based?
@@electrician247 I'm based in Belfast. Just think it would be a good investment in the house but don't know how much it would cost.
@@ciaranhughes8705 we supply and install them for £900 + VAT as an average. Depends on the supply circuit and wider electrical install. We don't cover that area tho
@@electrician247 Do you know the best place I could buy one to get someone local to install it.
@@ciaranhughes8705 City electrical factors stock them.
Im just looking into getting one of these after knowing about them for a few years, now the question is... which one to get?
I'm going to go for the heated option but there is a new pricer version with carbon filters, are they necessary in your experience?
Do you generally smell the attic through the air coming into the home?
If thats not necessary which model would you recommend out of the range?
Nox filters are best. Always worth it in polluted areas and dusty lofts 100%
@@electrician247 Thank you very much, I'll go with that so. I thought my husband could fit it himself however from you video it seems to need to be wired to the mains? Does it not come with a plug?
@SiobhdhraMc some of the PIVs do but the nuaire doesn't presently.
@@electrician247 Thanks for taking the time to reply!
I’m sending you a hug if your reading this 💕
I'm responding with a formal complaint of harassment as defined in the Equality Act 2010.

I just fitted my unit
How long will it take for it to take full effect??
Mine has been in 24hrs and I still had bedroom window condensation this morning
It wont clear the problem on its own or within 24 hours. You need to ensure the loft is well sealed from the house. Spot light holes, loft hatch etc. You need to ensure the loft itself is well ventilated. Extractor fans to bathrooms/kitchens. 10mm undercut to doors minimum for airflow. insulation to loft. Trickle vents to windows ideally. With the above in place it still isnt a solution in full and condensation will still form on the coldest days. However it will improve things without question. It depends how damp the property is and if the heating is utilised alongside the PV. But results should be noticeable within 2-3 days in most circumstances and this continues to improve overtime. The best way to monitor the actual air quality is with a humidity meter. But dont expect condensation to disappear in full. That is not how these work or a realistic expectation. Thanks
@@electrician247 thanks for the response,
Yeah I have covered all the above,
I moved in fitted a inline extractor fan in the bathroom, all new windows have trickle vents open and the loft is vented and the hatch / down lights are nice to tight
We have been previously using dehumidifiers so wanted something more permanent
I am going to cut 10mm off the doors this weekend 👍
We don't have any mould it's just the window steaming in the mornings we are trying to battle
Should it stay on constantly?
Yes
@@electrician247 ok thanks for the reply, is there an off switch just incase?
What if the outside and therefore the attic humidity is high (87%)
It will be raining 🤭. At times of high humidity the impact of the PIV is reduced. But generally that is a very short duration. It is essential loft spaces are well ventilated to outside and sealed to inside. Such as loft hatches, spot lights and other ceiling penetrations.
Mine is blowing cold air out all the time, my house is freezing, how do I turn it down please so it's not cold all the time
Do you have the heated version? If it's the newer model controls are under the vent cover plate. Older version controls are in the loft with the unit. New unit has a round vent old square vent
@@electrician247 the controls must be on the unit, I've checked under the round thing, I will have to get in the loft, hope there's no spiders lol
@@sarahlocke9026 did you find out how to turn it off?
I have one too and have no idea how to switch it off completely?
@@andrewvasey16 the man next door also has one so I asked him to get up in the loft for me to turn it down, it was set for a 5 bedroom house, mine is way smaller house than that, he turned it down and it feels a bit better but I think it needs to be turned down more, the controls on it are on the unit itself up in the loft, hope this helps xx
Drafty.
Kind of the idea. However a well installed system with integrated heater is only really noticeable if you stand directly under it.
It doesn’t make any sense. MVHR that’s what you should install, not that overpriced toy 😂😂
Is your opinion and your entitled to it. But it’s wrong. Lots of homes don’t have the need, want or budget to install MVHR. Never mind the redecorating afterwards. We do install plenty of MVHR when appropriate, like all professionals out there working with clients to solve problems rather than trolling away on a keyboard.
@@electrician247 I agree, I shouldn’t say that, apologies.
But after seeing so many problems with loft conditions , and I know UK building standards I can’t agree to install this device in loft. We can still find over there old asbestos insulation , asbestos water tank,plus no breathable felt, plenty dust etc. If the person who installs it is aware of this that’s fine , but in many situations unfortunately people don't know about it.
That’s why I think it’s better to not promote this device.
@@Matt.ffgmatHexPulseChain professional installers will be surveying loft spaces. If asbestos is found no work takes place and that is beyond just these products. Generally most loft spaces do not contain asbestos as accessible to occupiers. You can’t discredit a product and not offer it as a solution based upon that imho.
Again a properly specified system will take into account the sealing of the loft from the house and also the external ventilation into it. Ensuring the conditions are suitable for the product.
These are a very cost effective way to help tackle poor ventilation when professional installers are utilised.
There is no promotion here beyond exactly that. If you are not comfortable installing them and don’t carry out asbestos surveys then 100% you do right to not offer these products. But that doesn’t mean other people who are capable can not.
