Excellent video, and I'm glad this has resolved your issue. We were experiencing similar a few years back, but luckily, a dehumidifier solved it for us. We bought a Pro Breeze unit and placed it in the cooler part of the house. As you mentioned, keeping to a consistent temperature is also key to this. Thanks again for the video and great channel too.
They really do work - I considered the heater version, but it’s really not necessary. Easy to install and our house just feels more comfortable. I’d argue that they save you money - it’s cheaper to heat a dryer house.
We've hardly any condensation as we use a dehumidifier for drying the clothes in a room rather than the radiators like we used to but the RH level is still 72% plus after opening the windows to change the air etc. We tried placing the (expensive) dehumidifier at the top of the stairs but, whilst it was keeping the upper levels at a reasonable humidity, it just wasn't really affecting downstairs. We've now bought a heated version of the Nuaire Drimaster and it's due for fitting tomorrow, I'm doing the fitting and an electrician is wiring it up to the lighting circuit in the loft. Fingers crossed...
Sorted and works a treat, took a few weeks to get there though. Now at 55% RH downstairs on speed 4 so will eventually drop this if RH gets too low. NO condensation at all on the bedroom windows even in this freezing weather !
We’ve had ours in for just over 5 months (Jan ‘24) the first month or so you can definitely smell the loft but it isn’t overwhelming. It has died down now and only the odd occasion you notice a smell and even then it’s only right under the unit.
The PIV channels air from the loft into the house. The air in the loft should be less humid, if you have condensation issues it sounds like there is insufficient ventilation? You might need some vented roof tiles or vents in the soffits
Okay, so im in Dublin and the weather has shifted now in Nov '24, we are having big condensation problems in our bedroom. We probably have the same weather and home conditions. This looks like it could be the answer - I've done the usual research. How are things now?
Hi mate, I installed one of these and I can’t figure out how to make the heater come on. I think it’s the C18 setting, which is between 5-20, do you have any tips on what I should set it to, so it comes on and blows Warner air please?
Good to see you back mate. Have you noticed any increase in heating costs due to the cooler air being pumped in? Ive been considering one of these, the idea of continuous fresh air is appealing.
Thanks it's good to be back. The air is heated as it's pumped in but people have said even without the heat option on they haven't noticed any difference
The unheated version on mid setting costs about £2 a month (depending on speed setting), we have it on speed 4 which is about 10 Watts an hour, so 240 watts a day a day times by 30 = about £2. With the heater on it will be quite a lot more depending on the set point you have it at BUT it will only actually 'heat' the air a couple of degrees anyway so IMHO not worth having on. We actually have the heated version but I switched the heated element off.
I can see how one would be good for rooms immediately under the loft space, but wouldn't be able to fit where the room affected by mould/condensation has a habitable room above.
What they don't tell you is they don't suit every home, there are a set of conditions or criteria these units are suitable for which this video does not cover. A great video but it can only show you the positives in a house where it appears to work well but some people I know have installed them and they don't work so great.
stupid idea... 60-70% of all UK houses have in bathrooms already fitted, extractor fans... all you need to do if wanting to achieve the same affect, is swap the already fitted fan in/ out ducting in your loft, three minute job with one screwdriver after hitting isolator switch, and you will have air from outside being pushed into your rooms, so reducing on mass the humidity. But is that really the solution. Yes as that is exactly what a trickle vent is right? But some hard stats on this needed, and a £20 humidity sendor with wifi, in every room in a house, monitored to see/ before after affects, and keep the weather outside and heating inside the same to prove it.
well there really isnt any easy efficient way is there .im in S.E bc canada i get 4 seasons right now im in the rainy to snow transition . i have run a dehumidifier but dont want to waste electricity plus the cost .maybe ill just try calcium chloride to pull moisture from air .its crazy cause you can just boil potatoes at supper time and steam out the house .
Great to have you back. I was beginning to worry.
Thank you, it's good to be back. I've been busy working on other projects but I'm really trying to get back into UA-cam
I have one of these for a few years. Great, especially for old houses especially.
Good to hear!
Been mulling over getting one of these, looks like I will getting one now.
I am in a bungalow so its pretty straightforward to get one fitted.
They are really worth it 👍🏼

The dehumidifier just wasn't enough for us. Thanks for watching 👍🏼
It's insane how much water we collect in our pro-breeze.
But I'm really liking this system. It makes a lot of sense on a lot of levels.

Interesting bit of kit. Great video.

👍👍👍 Great review. Thank you
You're welcome, thanks for watching 👍🏼
Great video. Thanks! How often does the filter need replacing and at what cost?
Not sure about the filter but I suppose it depends how dusty the loft space is
Have you noticed a drop in temperature. How ofter do the filters need changed as roofspace a arw very dusty
No drop in temperature as the air is heated as it's pumped in.
Not sure about filters yet but I suppose it will depend on how dusty the loft space is.
Great video m8 well done, hope it works ok
Thank you 👍🏼
Is there any (unmitigated) fire risk with something like this that runs 24/7?
Thanks for the video. Can this be wired up with the lighting mains circuit and a fused spur?
According to my electrician, yes...
Any issues with loft smells? Mines a 1930s house too but roof tile direct on Batten (no felt) so I gets a bit musty in winter.
We haven't noticed any smells but our loft is fairly clean with a new roof
We’ve had ours in for just over 5 months (Jan ‘24) the first month or so you can definitely smell the loft but it isn’t overwhelming. It has died down now and only the odd occasion you notice a smell and even then it’s only right under the unit.
Does this one blow cold air in the the landing or have 400Watt heater built-in that costs more than a few pence per day?
He says in the video around 1:35 about this.
It's got a heater
We have condensation problems in the loft, could this be fitted in the loft without the vent part in the ceiling perhaps?
The PIV channels air from the loft into the house. The air in the loft should be less humid, if you have condensation issues it sounds like there is insufficient ventilation? You might need some vented roof tiles or vents in the soffits
Rather than get vented roof tiles, a hack is to place round pipe lagging where the felt joins to increase airflow...

It doesn't blow warmer air as in like a fan... tbh I wouldn't turn the heating element on as it only 'heats' it a couple of degrees anyway
Good to see you back mate. Have you noticed any increase in heating costs due to the cooler air being pumped in? Ive been considering one of these, the idea of continuous fresh air is appealing.
I have one installed come the winter your bills will jump quite abit makes my house really cold
Thanks it's good to be back.

@@spendtimesavemoneydiy cheers mate, that's good to hear.
@@THEGSADVENTURER we already have solar panels on the roof as it is so they're offsetting our costs a little bit.
Fantastic video, I’ve been looking for months to solve this condensation problem, can’t thank you enough 👏🏽👏🏽
You're welcome, hope it works as well for you as it does for us
How much does it cost to run? We're getting our loft borded in Jan and now thinking about getting a PIV installed afterwards 👌

We installed a PIV (same make) 5 years ago. Hasn’t made any discernible difference yet. Sadly.

One of Europe's best cities to visit. Public transport is also excellent.
