|Where does CO come from?|
CO is produced by incomplete combustion in a heater or boiler. As burning fuel is starved of air it generates higher levels of CO, this is due to there being insufficient oxygen to produce carbon dioxide (CO2). CO2 is produced when carbon in fuel is fully burnt and all the heat released. With a shortage of oxygen the carbon does not fully burn and produces Carbon Monoxide (CO).
In a domestic boiler, CO can be produced by the following problems:
Any of the above causes, linked to conditions where CO can enter a room, is a recipe for disaster or ultimately.........
