Why do you need a CO detector? Quite simply to survive! CO poisoning is dangerous and invisible. They can be caused by poor combustion of gas and block the oxygen in your body, leading to suffocation. A detector alerts you when CO is in the house and can save your life if there are problems with the flue or flue components. So, for a gas boiler at home, a CO detector is a must!
