Where does Carbon Monoxide come from?
Carbon Monoxide can be produced by gas or oil appliances like a furnace, clothes dryer, range, oven, water heater, or space heater. When appliances and vents work properly, and there is enough fresh air in your home to allow complete combustion, the trace amounts of CO produced are typically not dangerous.
Carbon monoxide comes from the burning of fossil fuels … that’s gas, oil, coal, wood. Becoming drowsy when you’ve got your oil heating and combi boiler on is not a good sign. It may be that one or more vents are not open to allow the carbon monoxide to escape. Dependent on where your boiler is situated … if, for instance, it’s situated in the chimney breast (a previous fireplace), could indicate that you may need your chimney sweeping due to a build up of soot. There are carbon monoxide detectors that you can purchase from DIY stores, though I’m not sure how much they are. You should really get an expert in to assess whether it is, or is not, a problem with carbon monoxide. It’s no use finding out when someone has died. I wish you all the very best of luck in finding out the cause of your drowsiness.
