Yep, we did. Worked for us. Not the cheapest but we found them good to work with. ESCROW protection on stage payments was attrractive. It was around 7 years ago now mind.

So close, Dave. I think I'll have to give you that. We have three showers but only use one of them except when visitors are staying. It's been so long that the traps in both of the others had dried out. Took me a day or two to figure it out, but let's just say I ended up following my nose 😉

Our loft is inside the airtight envelope.

No, we've been in the house for over 5 years and this has only occurred in the last fee days.

I'll give you all a clue. This was caused by something we didn't do rather than by something we did.

That would have been a pain, but no.

No letter box No log burner Could have been but wasn't 😉 No extractor fan (MVHR but not that) No son

Not even close

Sorry, but no

🤣

Nope

Nope

If only life was so exciting 🤣

Nope. Keep trying, it's something that could happen to anyone.

Not even little mouse holes

None of the above

Nope, we never open windows.

As the title suggests, we have recently experienced a sudden loss of airtightness which was manifesting as internal doors that had been left ajar slamming shut as others were opened or closed. Mystery now solved as to why, but the question is, what was causing it? Answers on a postcard below...

An airfix Spitfire hanging from the ceiling, but next summer I get to fly in a real one. Merry Christmas everyone.

Reminds me of an old Odeon cinema.

We had to put in soakaway crates, lots of them, despite being on fairly free draining land. Complete ban on connecting to existing surface water drains here, never mind discharging surface water to foul drains. Ridiculous thing is that the surface water drainage adjacent to our property discharges to a stream less than 200 yards away, and that runs direct to the sea. Edited to add: Not that any of this stops Southern Water from discharging effluent into the Solent 🤬

Maybe you need to think about it more 🤔

Hi Mike, it was originally suggested that speed 2 was 'normal' but we've found, through trial and error, what works best for us. Air quality was the main objective for the house due to Mrs NSS's lung conditions, and so far as any monitoring is concerned, her lungs know when the intake filter is close to needing changing. We have the Paul Novus 300. Pic of the control panel below.

Five years in we've experimented with different settings and settled for a summer programme and a winter programme. In summer it runs on speed 2 (of 4) from 7pm to 7am and speed 1 from 7am to 7pm. In winter we reverse that. If we have a particularly hot spell, as earlier this year, then we up the night time speed to 3. Summer bypass is programmed to avoid heat recovery when outside temp exceeds 20C. Speed 4 (boost) is reserved for the likes, for example, of when cooking fish and runs for 60 minutes unless manually stopped. In all bar boost mode there is no perceptible noise in the house. We never open windows, and doors are seldom open for more than a few seconds.
