For example, a farmer uses 8,000 gallons of propane to cure his crop. The same 8,000 gallons of propane equals approximately 5,247 gallons of heating oil. The maintenance cost on modern oil burners has been dramatically reduced because of modern solid state electronic controls on oil burners. Oil burner reliability is unsurpassed in the heating industry. Through proper combustion set-up and fuel filtration, the oil burner will give many decades of steady service.
Gaseous fuels have more water in the combustion gases than liquid fuels.
The excess water in the combustion gases causes more heat to go up the flue with gaseous fuels. Heating Oil is a liquid that can not support combustion below its flash point, which is generally around 130 degrees. You can throw a lit match into heating oil and there will be no explosion or fire. Fuel pricing is directly related to crude oil prices. National Fire Protection Assoc.
