Oil vs. Gas: Learn the Pros and Cons of Both Heating Fuel .

Oil Heat is Efficient – A gallon of oil delivers 140,000 BTUs. Gas delivers only 100,000 BTUs per therm. Oil Heat is Comfortable – Heating oil creates the hottest flame of any home heating fuel (400 degrees HOTTER than gas), so your home heats up faster and needs less fuel to maintain temperature, so it feels more comfortable.

Varying the pressure of the fuel oil immediately before the orifice (nozzle) controls the flowrate of fuel from the burner. If the fuel flowrate is reduced to 50%, the energy for atomisation is reduced to 25%. This means that the turndown available is limited to approximately 2:1 for a particular nozzle.

Emissions from fuel oil combustion depend on the grade and composition of the fuel, the type and size of the boiler, the firing and loading practices used, and the level of equipment maintenance. Because the combustion characteristics of distillate and residual oils are different, their combustion can produce significantly different emissions.
