How to Install Nuaire Positive Input Ventilation PIV - Cure Condensation???

I run through a typical Nuaire Eco Heat HC installation from start to finish. Including a glance through the instruction manual.
If you are struggling with condensation and mould these really can be an effective way to help. I didnt mention it in this video but it also has benefits for Asthma sufferers.
I have created a Nuaire PIV playlist that has the other videos mentioned in this video. • Positive Input Ventila...
These are a great addition for electricians to offer customers, we install loads all year round.

Great content. Fitted a few of these now for family after watching your pervious vudeo. Too many people are unaware the damage mould can do to your house and health.

[@AyupStuggy]

I've just fitted my third PIV (Eco heat HCS) to try and prevent mould. These are great PIV units and worked really well on other 2 houses.

[@laurencelagden]

Perfect timing, I’m just about to order and install one of these.

[@ianmiller3182]

It's great how you go through the instructions. A lesson to us all. Even if the product is the same, the instsllation method can change. Best to find this out at the beginning rather than at the end.

[@electrician247]

I've made this mistake before 🤭. Thanks Ian and hope you are well.

[@MollyMortimer-gw8xj]

Hi mark great content. Can i ask where you get your PIV units from many thanks.

[@gvictoria2496]

I have just moved into a property and I can't figure out how to power it on and where it is wired into any ideas. I took grill lid of in landing but no lights display

[@user-og5ys3kv7s]

Great advice and clear explanation, thanks, Mark. You mentioned that the unit can be powered from a lighting circuit - I have an unused ring main circuit socket in the bedroom below (used to power a wall mounted tv) and can easily relocate it into the loft, would that be better and connect the unit via a 20amp DP fused spur? Thanks

[@electrician247]

Hi, I would used a fused connection unit rather than a DP 20A isolator. With a 3A fuse max in it. These devices consume little power. Thanks

[@user-og5ys3kv7s]

Thanks for that. One more question - just being cautious - the supplied spur has a 1amp fuse, you suggest a 3amp max. Would it be ok to go for the 1amp coming off a ring main?

[@electrician247]

@user-og5ys3kv7s that would be fine. But I would advise contacting a local electrician to carryout the work

[@tomohall2510]

Any idea why my machine won’t go into binding mode. I’ve followed the instructions to conect up a 4 way

[@tomprice3230]

Suffering from mould at my property but was put off the piv route by a lad fitting mvhr units for a living. Would anyone recommend the piv's? If so what model should i be looking into. Thanks

[@electrician247]

Deffo recommended from me. Heated models a must. Nuaire as shown here with 7 year warranty.

[@doonz1000]

what would I use in a single story house? would I need to install in each room?

[@electrician247]

If you have a loft space then one of these. If not then a flatmaster unit ducted through the wall. Ideally in a communal area of the property.

[@12988Jake]

I have insualted plasterboard, so a good 30mm of plasterboard, will the collar be deep enough to go into the loft enough to connect the ducting?

[@electrician247]

Yes, it's pretty deep with the heater cover plate. No dramas

[@12988Jake]

What do you mean by the heater cover plate?

[@electrician247]

@@12988Jake the PIV heater module sits onto the plate diffuser. If unsure speak to local installer

[@mattd6495]

Great video. I want a tradesmen to fit ours. Generally do people opt for electricians to fit these ? How long should it take generally take to fit it? Just working out how much it might cost to get someone to fit? Also can I ask why you wouldn’t recommend to buy one without the heat function? As I was planning to buy the Drimaster DRI-ECO-HC Condensation Ventilation Loft Unit (Hall Control) version for around £340. I didn’t want to spend over £400 on one really. Thanks Matt Thanks matt

[@electrician247]

Because they are very cold without a heater over winter. To the point lots of people switch them off defeating the object. Supplied and installed you would expect to pay around £800-£1000 BPEC ventilation engineer who are usually electricians would be the installer you need. Depends on the loft work, wiring and such for how long it might take.

[@mattd6495]

@@electrician247 wow really, didn't know they get that cold. Ill see what prices are like. The hot ones are from like £600. Might have to stick to the ones without a heater. As I've seen the hall control one for around £320. Brill. Ill check who can fit them around Derbyshire

[@electrician247]

@mattd6495 I really would say whatever you do get a heated one lol. We are often asked to replace those without through winter months. Think how cold the loft gets...

[@mattd6495]

Hi Ian, We have just had an electrician install our DricEco Heat. They have set it up on the default option. (1). When the temp in the loft reaches above 23degrees it will switch it's self off on standbu automatically. I wasn't sure if to switch it to another option? Thanks for the advice.

[@anonymous4201]

⁠@@mattd6495hey, how’s it going since having it installed? Do you went for the heated version I see? How much did you pay for the PIV and for installation? Considering getting one but like you I was initially considering the cheaper non heated version… I have a lot of condensation and mould in 2 bedrooms.

[@gauravguglani1]

Hi, how to remove the diffuser cap, do i force the hooks out with a flat screwdriver, just scared not to break them,Thanks

[@electrician247]

Firmly pull downwards in the area either side of one of the catches. Don't use a screwdriver. They just pull out

[@newhomediy]

Thanks for the video Can you let me know if this can be wired to the lighting circuit? I've seen other comments saying that it can be as this unit requires 1a. I don't have a mains circuit running in to the loft.

[@electrician247]

You would have to speak with an electrician who can review your lighting circuit and advise.

[@UpcomingChris]

Non heated uses a 1amp, Heated unit is 3amp. It can generally run off the lighting circuit.

[@vicmills7702]

Great video Does it only have one vent

[@electrician247]

Yep just a single vent

[@vicmills7702]

Okay thanks and do the do the whole 2 story house with the vent on the top of stairs. Also I have felt vents fitted in the loft. Are these okay to stay

[@electrician247]

@VIC MILLS 3 story and over you need a special model on the nuaire. Ventilation in the loft is a good thing so felt vents can stay.

[@vicmills7702]

@@electrician247 great thanks

[@user-yk9kl9pb1o]

Do you need an outlet duct through your roof? Where does the air go that is drawn up out of the house?

[@electrician247]

It's not drawn up it injects air into the house from the loft. Which is why you need good loft ventilation for these to work well. You can get through the wall vairents for situations lofts have poor access/ventilation.

[@musashi247777]

Which model is that without access to loft please

[@kevin77karthik13]

I just installed all the well And set my fan and temperature but I can not get a heating in my home, can you pls tell me what was setting I can do??

[@electrician247]

It doesn’t heat your home. The heating element takes the chill off the loft air. That’s all.

[@user-yd4hk2jy3e]

We have one of these without the heater. We are getting a smell similar to cigarette smoke. Is this common and how do we cure this please?

[@electrician247]

Check your filters and air quality in the loft.

[@user-yd4hk2jy3e]

Thank you. Are they washable or do you need to buy new ones. We bought the house when it was already fitted and don’t have any manuals for it. Thank you again.

[@electrician247]

@Deborah Musgrove some used to suggest washing but generally most say to swap them now.

[@sjcsystems]

@@user-yd4hk2jy3e when I moved in, I had something similar with the bathroom extractor fan. I changed the pipe and that fixed it, but another alternative is to run the extractor and spray a scented disinfectant into the grill.

Hi, how much do you charge to supply and fit one?

You couldn't unless the loft has a sealed and ventilated eves space. You would require a flatmaster that inputs air via a duct through a wall.
