Answer: No, it is definitely not carbon monoxide. I can see why you are worried though. When you turn on your heater after it hasn’t been used for a while, the dust on the heater gets heated up and that’s what creates the smell. It isnt something one should be worried about as long as the smell goes away few minutes after the heater has started running.
