It's a modern 1976 house so any internal moisture just
finds its own way out (mostly thanks to the hugely
excessive air leakage anyway). I adopt the German method
of opening all the windows for a few minutes occasionally
anyway.

Ah, stossluften - shock ventilation - yes, I do that. I think it's quite a continental thing. My Dutch relatives even hang out their duvets every
morning. It seems counterintuitive, letting all the heat out. But it soon
comes back, stored as it is in the building/contents.

I also have an Ebac PowerDry dehumidifier and at the end of
September I turn it on at its minimum setting and just
empty the tank every other day-ish. My Lidl temp+humidity
meter reads up to 70% by the end of a hot humid summer
but over a period of a month or so (Oct + Nov) drops to
somewhere in the mid 40's.

I'm not quite that rigorous but when the RH is up I'll dehumidify in living rooms if it's persistenly above 65%. Never achieved mid-40s though. I've got these scattered around the house:

I've used them since reroofing and a 'warm roof'. No problems so far - except
I lost one when the battery went and I'd forgotten where I'd put it. And TBH I haven't had a detailed look at the data logs - there's simply too much.
