Condensation vs Nuaire Drimaster

are these silent in operation chaps?
They aren't silent but it's a non intrusive sound (hum). If you're ultra sensitive to noise, you can mount the fan unit with different methods, some hang them from ceiling joists / use rubber matting / use bicycle tyres to further isolate the noise. Slower settings very quiet, highest settings are a bit noisy and probably best just for daytime or noise being mitigated using above methods (or better).

Good old Pete the damp mythbuster has got something to say about the loft venterizer at about 7 minutes in....

Righto.
I think he's a bit of a nutcase.
BUT. He is a period property remediation expert, things like reinstating void ventilation, removing cement render, lime rendering, ground drainage, breathable fabric etc etc, he's the only guy that calls out injection dpc people. I believe he consults for national heritage England or some such establishment. And a nutcase.

There's several comments with that video from people saying it's worked well for them.https://www.youtube.com/watch?v=O0Q5zZuzgLU
I suppose his comments could be valid if the loft was uninsulated and unventilated, but he should have qualified them. But he seems like the kind of person who sees everything as black or white.

You’ll be wanting the flatmaster for that.
Yeah i've been looking at that and thinking about how it would work here - it looks like the idea is largely the same; look to locate the discharge vent somewhere central for efficient distribution to all rooms and run ducting to an outside wall for the intake. I have a central hall area that all rooms lead off which would be suitable for the discharge but it isn't near an exterior wall. The bathroom vent runs along boxing at the top of the lounge so it maybe possible to tap into that or potentially go the other way and run ducting above the kitchen cupboards to get to that outside wall. All the pictures I see show the unit installed upright (standing on the thin depth) but is it possible to install the unit laying flat (on the larger width)? Wulmund said:
I bought a Nuaire Drimaster Eco HC. I don’t know if anyone knows of a wall unit that lets you manually select the fan speed? I can see ones that control heat (this one doesn’t have a heater) or ones that vary the speed according to humidity. I’d like to be able to manually select one of the 5 settings but it doesn’t seem like either of those units let you do this? I have an older house and the ceilings are quite high so it’s hard to get up there to change the settings manually! Thanks for your help.
As far as I know there's only the normal/boost switches.https://www.ebay.co.uk/itm/Nuaire-Drimaster-Eco-2-...
You can have the boost switch if you have the heat or not, you just need to have the link model if yours doesn't have heat. (All heat models are sensor ready by default I think).
Why do you wish to keep changing the fan speed?
I bought and fitted one a few weeks back. It was wired up on Christmas eve and the next day the windows were free of condensation. I'm very happy.
The 23rd was very similar morning temperatures and I had to do my normal morning wipe down.
As most people have said, the hall way is a bit fresher than before with 30l/min air flowing in but we've got a south facing roof so will get some solar gain with nice weather.
My humidity monitor in the kitchen has dropped 10%. It's only a sample of 2 days so I'll monitor and report back if it was just a fluke.

Well, that's a week almost done and condensation has been cured, even in the coldest of nights/mornings.
I've reduced the speed down to 2 last night as the icy air was making the hallway a bit nippy and my 3 year old was complaining. No effect on the condensation in the morning though so I'm happy!

One month in and all condensation has gone.
At first it was all good and then on colder days I noticed that one bedroom was still suffering minor condensation, this room had curtains and shutters so we then decided to leave the shutters open and shut the curtains. This did the trick and now we leave the shutters open and close the curtains at night. Previously before installing the Drimaster we had tried the same approach with open shutters and closed curtains to no avail.
Absolute winner and if anyone is wondering if its worth the punt (after all these arent cheap) then yes it is. We got really bad condensation across the front of our house (North facing) - I mean windows absolutely streaming you couldnt see out of without wiping down and now we have no condensation whatsoever.

Looking to install a PIV in the next few weeks due to consistent issues with condensation which have got really bad this year.
Can anyone advise whether the models that feature hall controls are worth the added investment? Are the units normally set and forget or are there occasions you might want to ramp up the air flow /
Equally does the heated version make much difference to the incoming air to justify the additional purchase price & running costs?
