A neighbour bought a detector and asked me to fit it. As her Combi is in an
upstairs airing cupboard, I fitted the detector in the cupboard (the door
isn't especially soundproof)
Would you agree with this - or would you take the view that it should be in
a habitated area - such as in the hallway.

Interesting. Density of CO is nominally the same as air.
I guess the correct place is where it visible and a habitable area,
close to the potential source of CO.
I also believe that a full airing cupboard may have limited airflow, so
it would be impossible to second guess the position of highest
Aren't there rules about placing combustible materials in the same
enclosed space? Don't such enclosed spaces with boilers need fireproof
doors? I recall a tale where a door was removed to satisfy regulations!
(And promptly put back!)
NO! -CO is a bit more than half the density of air. Town gas was
largely CO and was sometimes used to fill balloons although the 'lifting
power' was less than hydrogen.
Hence a good idea to locate a CO detector high up.
Town/coal gas is lighter than air because it is mostly hydrogen.
I only ever heard of CO detectors being recomended for conventional flued
appliances (ie with chimneys)
Seems pointless for a room sealed appliance.
The destructions on one I bought recently stated it should be mounted,
not closer than 2 metres and not further than 4 metres, from the
probable source of CO.
So I assume the hallway would best fit that.
What I have done is looked at where the sources of CO could be and which
areas of the house are frequently habitated.
I then bought 4 interconnectable CO detectors.
one went by the combi boiler in kitchen which vents outside via a
another went by the wood burner which also happens to be the lounge and
there is a chimney stack for the wood burner.
Another went in the master bedroom (Which happens to be above the
lounge) simply because we sleep in there AND there is a chminey stack by
the bed where said fumes from wood burner pass through.
the last one went in the loft near the wall where the chimney stack
continues up. This is in case the chimnet stack ever leaks into the loft.
The lot is all interconnected and there is also a connection into the
house alarm panel via a spare 24 hour zone.
