Positive Input Ventilation Flatmaster 2000 - Condensation

lightyearsboi

I live in a new build apartment and was suffering from condensation and mould problems. I bought a dehumidifier a couple of years ago and that stopped the mould and limited the condensation but was expensive and noisy to run.

After researching online I had a Nuaire flatmaster 2000 fitted two weeks ago. It has solved my condensations problems, the humidity is now in the 50's. It runs really quietly and I no longer need to empty out water.:)

There is little to no control over just where the air is blown or drawn from (it takes the path of least resistance leaving 80-90% of the house unchanged ) so you have a miracle solution to a problem that shouldn’t exist in a new built therefore insulated to comply with building standards house (dew point being around 12 °C if built to correct standards these should only occur in roof space )

They can work better in older buildings no insulation etc but new build better cheaper more efficient remedies out there and conditions shouldn’t be happening in a new build to start with so do you sell these by chance :rotfl:

First of all I'm talking about an apartment not a house.

When I walk past the other apartments in my development in the mornings most have condensation on the windows with some with mould on the blinds. My friend who was renting in the next block also had lots of mould problems.

In the apartments people have to dry their washing indoors, washing lines are not allowed outdoors. As the new build is so insulated all the damp air is left in the apartment. When the guys drilled through the wall (gable end wall) it was solid concrete, insulation and brick.

When doing my research I read some comments like yours that weren’t helpful at all. "new build better cheaper more efficient remedies out there and conditions shouldn’t be happening in a new build to start with" What remedies are you talking about? We already have trickle vents that are always open, they do not work. I cannot leave windows open during the day as I am in work and it is a ground floor apartment. The humidifier did work but was expensive to run, too noisy for my apartment and I had to keep emptying it.

"it takes the path of least resistance leaving 80-90% of the house unchanged" Wrong ALL my windows now have no condensation and the readings in the bedroom and living room are in the 50's, prior they were 60+. Mine is installed into a central hallway.

"do you sell these by chance" No I do not. I am just glad I found something to control the humidity

Irrelevant as manufacture states "designed for homes":)

I'd guess a high % of those that don't have mould/condensation problems are not using nuaire

They don't have too they choose to and damp air is a misconception the air outside may have higher humidity than that indoors so where does your dry air come from ?

Condensation You need to understand the basic heating and ventilation ? this may help http://www.axa.co.uk/help-and-advice/my-home/what-causes-condensation-and-how-to-stop-it/

Air takes the path of least resistance basic rule of physic's? I do not disagree nuaire help so can opening a window and ventilating , fitting a fan etc ....
Preventing condensation is much easier than attempting to control/ cure it if you wish to know how you need only ask ?

Clue is in the name flatmaster, it is made for flats.

All but one apartment on the ground floor when I checked had condensation.

Again not helpful did you read my post? I am in a ground floor apartment I could not leave the window open during the day when I am not at home. The humdity in the mornings was 70% + and we have to dry clothes indoors (the lease does not allow us to put up washing lines). We already have a cooker vent and the bathroom and ensuite have fans that are used. The flatmaster allows the air to get in without having to leave the window open. It also has a heater so the air is not suddenly cold as it is when you open the window in winter.


The whole point of the post is regardless of your opinion of what "should work" is that it this does work for me. Have you actually used one? I am not sure why you are so against them?

You say all "apartments" but one show signs of condensation conditions this points to something being wrong poor design , insufficient ventilation , insulation etc You’ve not bothered to read link above which is why you’ve not helped yourself or is it you have and don’t understand it ?
May help you more

Warm air holds moisture, cold air holds less with it so far ? You are in taking less moisture laden cold air (Possibly heating it ) then distributing it throughout your flat or as you say apartment ta da " Nuaire flatmaster 2000" ventilation heater fan ta da exactly the same...
Very very basics Produce less moisture, Ventilate to remove the moisture, Insulate and draughtproof…. As a starter external extractor within kitchen would likely lower moisture 30-40%
Average moisture produced per day
Breathing - 0.3 l (asleep) 0.85 l (awake)
Cooking - 3 l (gas cookers create more)
Personal washing – 1 l
Washing and drying clothes - 5.5 l
.
I have used them yes and designed HVAC, MEV systems even ones used by nuaire among others? They have there place but a new build and all showing signs as you say there is something fundamentally wrong. as you've fitted one you would I assume own property ? If so you would know if there NHBC standard built?

Yes I have already read that when I was doing my research thank you! The property is very well insulated, they are 10 years old. Windows have open trickle vents. I know warm air hold more moisture like I said I did my research.


"As a starter external extractor within kitchen would likely lower moisture in home by 40-50%"

You assume I've not tried anything before, like you assumed I must be selling them...I already said I have external extractor in Kitchen, bathroom and ensuite and the humidity used to be 60%+.

Just got home from work and the kitchen / living room is now 46% and that is with clothes drying in the airing cupboard last night.

I could only possibly open windows after work and before bed, to repeat it is a ground floor apartment and we are not allowed to dry clothes outside. The flatmaster is now running quietly in the background at all times. Plus it costs next to nothing to run £3 to £6 a year!! and it has fixed the problem.

So you have Vent not a fan

I assume as you've posted "vent" in kitchen in previous post and fans in bathroom etc that you know the difference? As its now become external extractor in kitchen not a "vent" and 10 years old isn’t a new build I'll not bother wasting anymore of my time spam away........

I meant extractor fan.. The extractor fans however and the dehumidifier were all annoyingly noisy. The flatmaster is really quiet.

brightontraveller

Sound 39 db @ 3m that’s certainly not quite plenty of extract fans lower db and dehumidifiers (desiccant type ) add power consumption with heater (which without there even more useless) is more than your £ 5-6 per year.

The major floor in these type of units the warm moist air inside the property is forced 'looks' for an exit route, rather than being drawn out as it would with extract fans this can and often does produce more problems e.g. think condensation and warm air forced onto cold surface? More mold, condensation etc than they cure? Understanding how they work shows the obvious pitifuls unfortunately most don't.... [FONT=&quot]I’d say 99.9 % of the time better results can be achieved without installing these,

[/FONT]If your happy then alls fine for you? That doesn’t change the fact there are better, cheaper, more efficient methods out there or that these units are at best second rate at worst creating even more problems for poor householders.... You sing there praises I don't

Mines is not on setting 3, it is on setting 2 which is very quiet as the unit is located by my bedroom. the old desiccant dehumidifier needed to be on the highest setting which was loud and it cost me about £20 a month to run (running for around 7 hours a day)

You say that without the heating function they are more useless, but mine has been running the last 2 weeks without the heating function switched on and is working perfectly fine.

You seem to praise extract fans, but like I said I already have 3 of them as do all the apartments and if I walk past the windows of the apartments I see condensation and mould on blinds and on the plaster board by the window. (I did purposely check to see if other people had the same problem)

The air from the flatmaster is being pumped into a central hallway and is working well for all the rooms. I imagine if the apartment was laid out differently it might not work as well.

I'd rather one system that works and that is out of slight than anymore extracts fans. I am going to look at changing the bathroom and ensuite extract fans at some point just with the view to get ones that don't make so much noise.

"You sing there praises I don't "

I'm just happy I no longer need to either wipe windows or run a noisy dehumidifier.
