carbon monoxide alarm

So, how hot is it in the boiler cupboard then?

What is the boiler, have you had it serviced ever?

Any other problems with it?

Personally I'd avoid putting a CO detector in cupboard with a boiler.

quick check and "slight" service last december I will put the detector right outside the cupboard door then

should it be ceiling height or head height? (is CO2 lighter or heavier than air?)

Not being funny but didn't it come with instructions ? Personally I would trust my safety to 2nd hand.

The three I've dealt with lately have suggested about 2m away from the possible source and at a height of about 1.5m

Whoops - wouldn't !

Does it go off if you put it back in the cupboard but leave the door open?

not tried that, will do exactly that now, watch this space ta

Yes, they just show the potential rooms one shoulf go in, but no height mentioned

OK ta

I brought one a few weeks ago for my gas fire which hasn't been serviced wanted to check CO levels as the cat kept falling asleep in front of it [1] ;-)

Anyway it always reads 0 (zero) whehter at floor level or on top of the fireplace.

Does anyone know of a way of testing these testers, could I create a bit of safe CO to see if I can actually get a reading on my digital readout ?

CO2 is heavier than air. CO is almost the same density as air. This detector is for CO.

Make and Model of boiler? There's a much better than evens chance the boiler is room-sealed and the CO detector is serving no function. IF the boiler isn't (room sealed) then proper checking and regular servicing is a much better approach than CO detectors anyway.

had the local gas man in he said my balanced flue was not cemented in and the recent wind may have blown the fumes back in He says there was no visible evidence of a problem he relocated my detector just outside the cupboard. May need to cement that flue in properly

Press the test button?

Indeed.

No substitute for servicing however I dispute the claim that the CO detector is serving no purpose.

1. Something can always go wrong with your boiler
2. People have died of CO poisoning from other properties faulty appliances

That only tests the circuitry though, not the test element itself.

I would love to know a good way of testing the sensors though, I know of people who have held them near their car exhaust but I have no idea how this level of CO would compare with the kind of levels you would get in a property.

I think the official way to test them is to hold a lit cigarette 50cm away from them.

The problem with them is people start using them as the indication a boiler needs servicing, and they just aren't anywhere near reliable enough for that.

my in laws was placed in a passage near the bedroom doors (bungalow). anyway it started going off and they just unplugged it. one day when I went over I found that when they cooked using the gas hob the thing would register over
