It's called a constant flow vent then? Will have to read up on that Judd, thanks.

Just thought though...does it let in fresh air?

And, you say it's usually for new properties - I've read about those and I'm sure opening windows makes it useless or less efficient?

I've a 60s bungalow T pin not a 70s

Edited to add:

I read up on the NuAire Flatmaster, the one to put on an outside wall for apartments etc....is that the one you meant in your 1st paragraph Judd?
I bet it's about 68/9?

I've installed 3, one of which was in an old stone terrace house. I fitted a humidistat in the bathroom for that one which boosts the fan speed if condensation builds up above a certain level and I'm happy to report that the h/stat hasn't been needed up to press and the condensation problem has disappeared.

Hi Pesta. No, the one's I use don't let in fresh air, they're mainly for extraction. The one's you are talking about sound more like heat recovery systems where warm moist air is extracted and used to warm up incoming fresh air which is then vented back into the building.

The one's I use are these: https://www.alertelectrical.com/manr...FQMW0wodCjsP5g

Although installed as standard in larger new homes, they can be installed retrospectively in older properties. No need to open a window

Re: Positive Input Ventilation

Malcolm's on the right track (for a change).

Although, I realize that cold, bleak, miserable Britain is different from warm, tropical, Pumicestone Passage paradise.

Here, if it's too warm - or even 'hot' - I peel off clothing and open all the windows to let the sea breezes waft through.
Too cool or even cold (rarely), I simply don more warm gear, close the windows a bit and (very rarely) switch on a heater.

Re: Positive Input Ventilation

People dry clothes on the radiators here when the weather's bad .. never open the windows and wonder why they get condensation on the windows and mould growing everywhere.

Re: Positive Input Ventilation

Pesta, have you used a humidity meter to assess RH levels?

I have one if you want to borrow it.
