Thanks for your reply.
I was thinking winter rather than summer, but would be interested in the circumstances of both please.
Currently doing this, as I've been in Australia for the last 6 months, returning back a week on Saturday.I was thinking winter rather than summer, but would be interested in the circumstances of both please.
Heating is set for 8, and looks like my humidity levels are rather high, with the PIV still running
Looks like I'll have some fun when I return.
Current State of temps and humidty
PIV energy usage for the past 2 weeks
Last 2 weeks of humidity levels where PIV is installed
Just hope that sticking the heating back on for 48 hrs at 19 before I arrive home helps.
Interesting info here, thank you.
Important to remember the difference between absolute and relative humidity here I guess.
Cooler air cannot carry the same volume of water so the relative humidity of the air will be higher regardless.
I think low level background heat probably is important to keep the fabric of the property from dropping too cold and thus allowing condensation to form.
But I’m thinking a PIV might really help this also by keeping air circulating and introducing potentially dryer air.
The only concern I can see is if the air it pulls in happens to be warmer than the fabric of the house.
I guess the ideal scenario would be temperature differential sensor that meant it turned the PIV off if the air outside is warmer than inside the house.

I've returned from 10 years of lurking to post on this mega thread after being inspired by everyone's success.
It's installed in a 1900(ish) terrace with a loft absolutely FULL of black dust (coal/fire/chimney related? No idea..) that has a really vile damp/musty smell about it.
The loft appears to reasonably well ventilated but the 'loft smell' still manages to occasionally appear in the house since fitting the Drimaster. I wondered if anyone has any solutions to this? Do the added 'upgraded' NOx filters avoid this? I imagine if the smell has made it through I'm probably also breathing in some kind of ancient loft dust which isn't what I had in mind when fitting the thing.
Thanks!

I’ve a Victorian detached with a similar loft by the sounds of it. When we lit the log burner the end of last year I noticed the Dri master was sending the smoke smell about. Where we are there is a significant down draft as we are on the Worcestershire side of the Malvern Hills. This is countered on the chimney by using a spinning euro cowel that draws the smoke away.It's installed in a 1900(ish) terrace with a loft absolutely FULL of black dust (coal/fire/chimney related?

What I found was some of it was re entering the loft space when particularly windy. The PIV was then sucking it onto the upstairs landing. The NoX filters have cured this. I saved over £100 buying online from a company who ordered it from Nuaire.

Thanks for that Mike - to clarify it's more of a damp / musty old coal dust type smell I'm getting as our fireplace has been capped/blocked and out of use for years now.. Hopefully the filter would still help What I found was some of it was re entering the loft space when particularly windy. The PIV was then sucking it onto the upstairs landing.

- glad to hear they worked for you!robemcdonald said:
I’ll have a word with the sales director tomorrow and see if I can add NoX filters to the deal.
That would be great, thanks Rob.Being the industry professional here, would you normally recommend the NOx filters anyway for just the "vile old loft dust" and damp smell issue? I'd rather not be breathing that rubbish in!

The normal filter should get any particulate over roughly10 microns in size, so is pretty good anyways.
