Yes. Heating oil is one of the safest fuels ever developed. Oil produces low emissions, is biodegradable, and it won’t burn in a liquid state. If a lit match were dropped into a container of heating oil, the oil would extinguish the flame, just like water does! To be ignited, oil must be vaporized. This only occurs under pressure at 140°F.
Properly set and maintained oil burners produce very low, safe levels of carbon monoxide as a normal part of the combustion process. And if there is ever a malfunction in your heating system, there’s little or no need to worry about an explosion or the release of carbon monoxide into your home.
