where is alarm installed ?

 

 

about 3 mtrs away from the woodburner on the ceiling. What could it be about the position of the alarm?

CO alarm will signall if batteries is low.

 

 

Along the same line as this:-

 

If the alarm is going off, remove it from the wall/ceiling and take it outside. If it continues to go off it is a faulty  carbon monoxide alarm.

 

But as mentioned before get someone in and get it checked. Better to be safe....

I seen alarms installed just nearly on the stove😬, so asked just to be sure it is in proper location .

Thanks. I have none of these! Everything else is electric.

Have you had your chimney/flue checked and swept?

how old is the alarm? They reckon they need changing every 10 years because the sensors can go, just to add another thing to think about.

Can’t help with the initial question but, isn’t CO2 heavier than oxygen. I thought that CO2 monitors should be mounted at head height, not on ceilings.

is the room airtight try opening a window a little and see if it makes a difference to the draw/ burning of the logs? 

i think that co2 alarms are suposed to be about a foot down from the ceiling

It is a CO monitor for combustion devices because CO, carbon monoxide, is very poisonous as it combines better with blood than oxygen

 

CO molecule is about 28 gram per mole and air is mostly nitrogen 28 and oxygen 32 so all roughly the same, as you say CO2 at 44 is heavier.

Thanks. On days like today (very low wind) it's practically impossible to keep a flame going, unless I'm on it all the time. And even then....

I would say there is something fundamentally wrong then, to burn wood cleanly you must have a good flame and a good draught,

Would you say to never keep the fire slumbering? I tend to do this overnight to keep some heat in the living room, or on days that it's not too cold, because otherwise it gets way too hot in the room.

Yes never let it slumber as slumbering just burns char, the heat that this gives off pyrolyses the remaining wood and the offgas from this rises into the chimney unburned where it cools off and deposits soot and tars in the chimney which eventually block it, but it usually catches fire in the chimney with often damaging results.

I reckon your wood ash is stifling your coal and your coal ash is stifling your wood. Clean it out and try one or the other for a couple of days.
