we have an old boiler and just lately, although it is serviced etc, i've been paranoid about carbon monoxide. this morning, i thought, this is daft, so nipped to argos and got a digital one.
we've had those little square ones in the past with the dot that goes black but i feel less worried now i've got something which flashes green, so i know it's working, and i can also see the measurements it's taking.
so, who else has not got one yet??
