Improperly maintained or faulty fuel-burning heaters can release carbon monoxide gas, which is odourless and colourless. Breathing in high levels of carbon monoxide can lead to carbon monoxide poisoning, resulting in symptoms like headaches, dizziness, nausea, and can even be fatal in extreme cases.
