Richardtr3a Posted November 7, 2021 Report Share Posted November 7, 2021 I need to buy a CO2 monitor to help with the air inside the house. I am looking for a small unit which will be as easy to read as a clock. I need to place it near the old boiler and near the oil fired AGA. I am sure that I had a small gauge last year but I can not find anything. It is surprising how many other lost tools that have turned up during the search. Now that the colder weather is here, we are having some headaches etc. The heating/hw is on, it seems sensible to monitor the kitchen and other rooms nearby. Can anyone recommend a supplier preferably in Lewes , Sussex or a major store with a local branch. Thanks Richard & B Quote Link to post Share on other sites

Hamish Posted November 7, 2021 Report Share Posted November 7, 2021 All combustion appliances like log burners need an alarm in the room but I think they are CO (no 2) and just “go off” when an excess is monitored rather than a numerical reading of the conc. which would need calibration I would suggest. so shop carefully Quote Link to post Share on other sites
RobH Posted November 7, 2021 Report Share Posted November 7, 2021 As Hamish says - Carbon monoxide not dioxide. I have one with a bargraph display which seems OK (and which has never displayed above zero, thank goodness) . Quote Link to post Share on other sites
Rod1883 Posted November 8, 2021 Report Share Posted November 8, 2021 (edited) We have exactly the one shown by Rob. Not bought from Amazon as I won't buy from that tax avoiding and high street/bricks and mortar retailer destroying entity. I think I got ours from Dyas when they had it on offer. B&Q have that one showing on their website at £23, link: - https://www.diy.com/departments/fireangel-co-9dq-wireless-carbon-monoxide-alarm-with-7-year-battery/193503_BQ.prd and a simpler one at £20, link: - https://www.diy.com/departments/fireangel-co-7xq-wireless-carbon-monoxide-alarm-with-7-year-battery/261146_BQ.prd I see that Homebase also have the simpler version at £18: https://www.homebase.co.uk/fireangel-carbon-monoxide-alarm/12814431.html Edited November 8, 2021 by Rod1883 Quote Link to post Share on other sites
brian -r Posted November 8, 2021 Report Share Posted November 8, 2021 Hamish is quite right , it is carbon monoxide alarm you need for domestic boilers ,fires etc, Most are just alarms that go off, so the one above suggested by Rob looks good. The local fire brigade fitted Fireangel devices under a safer homes schemes, so I would think they are reliable. Brian Quote Link to post Share on other sites
stillp Posted November 8, 2021 Report Share Posted November 8, 2021 There was a post on a Facebook group from a woman who'd disconnected the battery in her CO alarm because the constant beeping was giving her headaches... Pete Quote Link to post Share on other sites

You did not mention until your second post, matters that had already been raised. Please tell us, this is important and we need to know, who is "qualified" to service a CO monitor? Your expertise as an expert adviser is most valued. John Quote Link to post Share on other sites
Bleednipple Posted November 8, 2021 Report Share Posted November 8, 2021 Yep I want to know too. Might be useful when I get a speeding ticket. I could then claim my speedo was "pointless" as it hadn't been "serviced by a qualified person". Nigel Quote Link to post Share on other sites
ntc Posted November 8, 2021 Report Share Posted November 8, 2021 Both the boiler and cooker must be serviced by a qualified person they would check the levels and decommission them by law if faulty and no monitor would help you in a inquest Quote Link to post Share on other sites

Nonetheless, the Health and Safety Executive "strongly recommends" the use of CO alarms as an additional precaution. Which was why the OP was asking for advice on which one to buy. I'm not sure I'd be too concerned about the inquest, if I was the subject of it. Nigel Quote Link to post Share on other sites
john.r.davies Posted November 8, 2021 Report Share Posted November 8, 2021 So the CO monitor should be checked by a gas engineer? Well, CO is a gas, and it is inflammable so good guess! Perhaps you would recommend a gas engineer with this particular expertise? Quote Link to post Share on other sites
Hamish Posted November 8, 2021 Report Share Posted November 8, 2021 Isn’t the CO monitor a HETAS requirement where solid fuel is used at least. and apt timing for this discussion. https://www.hetas.co.uk/co-awareness-week/ Quote Link to post Share on other sites
Rod1883 Posted November 8, 2021 Report Share Posted November 8, 2021 The Fireangel device as pictured in Rob's post above is what we have freestanding, in our living room, to monitor the CO level as we have a small log burner. Our chimney sweep checks that we have this in place and that the test button works as part of his assessment and includes this on the certificate. The Fireangel device is, imho, therefore fine for a domestic setting - currently £23 from B&Q Quote Link to post Share on other sites

I agree Rob but because of what Richard said in his post I would get both appliances checked asap then buy a monitor Quote Link to post Share on other sites
Richardtr3a Posted November 10, 2021 Author Report Share Posted November 10, 2021 Thanks for all the replies. It looks as if I need a monitor to cover both CO and CO2 and we are hoping that we can find a warning unit that works well. I know how to buy one but what I am looking for is resounding approval from a current owner who is fully satisfied with the monitor over a few years. It is useful to ask your friends on the TR forum who usually have no sales interest. I am currently waiting for the technical department at Worcester Bosch to come back to me with some information. If any one has a top quality unit please let me know. thanks Richard & B Quote Link to post Share on other sites
Peter Cobbold Posted November 10, 2021 Report Share Posted November 10, 2021 Acute CO poisoning is very obvious: nausea, retching, headache, and it's unlikely that anyone would fail to be aware, if awake. The danger is if it comes on when asleep. But no-one has suggested a bedside alarm. Peter Quote Link to post Share on other sites
RobH Posted November 10, 2021 Report Share Posted November 10, 2021 You don't really need anything to measure CO2 Richard. That isn't a hazard outside of confined spaces like man-holes. The long term exposure limit for working environments is 5000ppm over 8 hours. The usual ambient concentration is circa 400ppm. Your house is going to seem unbearably stuffy long before you get to a dangerous amount. Quote Link to post Share on other sites
