I want a carbon monoxide alarm to place near my combi boiler. It needs
to be faily loud as the the boiler is in the loft. Can anyone
recommend one that's good value?

Thank you,

Just read your other thread. Carbon monoxide is heavier than air. Get
that boiler checked.

Actually it is about 3% lighter than air.

Sorry, I was thinking of CO2.

Just about any of them, I think the one I have on the boat is "First
Alert". It seemed very cheap for the peace of mind and it's ear
shatteringly loud.

They're tuned for firedamp (whatever that is).
You'll will need to get it re-calibrated for CO.

Ensure it carries a BS Kitemark on front.
Some in Robert Dyas were recently withdrawn.

I'd look for one that will automaticaly shut off the electical supply
to the boiler if it's tucked out of the way where you might not hear
it.

Carbon monoxide has a molecular mass of 28, and air an average of 28.8
so carbon monoxide is marginally less dense than air. With the air
movement in the loft tis is probably nor significant.

A CO alarm is an extra level security.

The main idea is to install, operate the boiler does not produce any CO.
Furthermore just about all modern domestic boilers are room sealed and if
installed correctly will have a vanishingly small chance of emitting CO
into the loft or elsewhere.

That's good to know - thanks. Yes, mine is a fairly modern one (1997),
and it's in the loft which is well-ventilated too, so what with carbon
monoxide being ligter than air, as someone said, I am now less
worried. But I'll get the detector anyway, just as an extra
precaution.

Thanks to all for the help,

Look it's not about CO being lighter than air.

1) The boiler shouldn't make very much at all. If it does the boiler is at
fault.

2) All gases produced by the boiler should be sent outside under all
circumstances. A room sealed boiler achieves this without trying.

3) CO is not (significantly) lighter than air but is likely to be warm
when produced and hence lighter in practice.

It is open flued (and flue less) appliances that need monitoring.

Good idea.

Aldi had some CO detectors that were made by the exact same company that
badges them for BG but at a quarter the price of the BG ones.
