hi there this might sound daft but just wandered if you need a carbon monoxide alarm with a combi boiler?
the reason i am asking is because my mum has had british gas service her combi boiler for the past couple of years and they keep trying to sell her a carbon monoxide alarm. it is a ex council house the council put in a new heating system not long before she bought it she had a alarm with her old boiler. when they put new one in they said she does not need one with a combi boiler. i also have a council house with combi boiler and the last time it got serviced i asked the guy about it and he said you dont need one.
i have also heard stories on the internet about the alarm going off and transco shutting off the gas till a gas engineer came round( 2-3 days later) and finding nothing wrong with the boiler
having heard stories about british gas i just wandered what you guys thought about it.
