Carbon monoxide is known as the "silent killer" as it is a highly poisonous gas that has no colour, taste or smell, making it impossible to detect without an audible alarm. It is produced when fuel burning appliances are incorrectly fitted, badly repaired or poorly maintained, or if flues, chimneys or vents are blocked.
We were delighted to run a competition with Ei Electronics for four lucky readers to win an Ei207 Carbon Monoxide alarm.
Here are our competition winners:
