Heating oil produces 138,500 British thermal units per US gallon (38.6 MJ/l) and weighs 8.2 pounds per US gallon (0.95 kg/l). Number 2 fuel oil has a flash point of 52 Â°C (126 Â°F). Most heating oil products are chemically very similar to diesel fuel used as motor fuel.
If you divide this into the 100 gallons of oil, you get 0.125. In other words, you used 0.125 gallons of oil per heating degree day. The longer the time you use for this calculation, the better your baseline figure is going to be.
