I've been asked, "What is a Degree Day?". Degree Days are what we use to help gauge how cold the weather is and how much Oil our customers will use. A Heating Degree Day compares the average temperate of the day to 65 degrees. For example if the High Temperature for the day is 45 and the Low Temperature of the Day is 25. The Average Temperature of the day is 35 degrees. We then subtract the average temperature from 65 to come up with the calcucation of 30 Degree Days for that day.
We then use the number of Degree Days to calculate a customers "K Factor" this is industry lingo that essentially just means how much oil a customer will use. We determine a "K Factor" but looking at the number of Degree Days we've accumulated and how much oil was used. For example, if you start out with an empty tank - buy 100 gallons and run out again after we've accumulated 600 degree days. Your "K Factor" is 6.0. A typical winter has about 4200 Degree Days - we can then project that during a typcial winter a customer with a "K Factor" of 6.0 will burn about 700 gallons of Heating Oil.
