The Degree Day System Service explained
Heating Oil and other fuels are consumed for heating based on how cold the weather has been and for how long. At Ingoe Oils we use this information to estimate when you need us to deliver fuel based on the Degree Day Unit. Degree Days correspond to fuel consumption needs, so for the purpose of scheduling when to deliver, Ingoe Oils tracks them at each heating season which typically is from the start of September until the end of May the following year.
A Degree Day is a unit for measuring how hot or cold it has been over a 24-hour period. Whenever the average temperature drops below around 18 degrees, you will have a Degree Day. That average is based on looking at the highest and lowest temperatures reached that day and based on that working out if it is then a degree day from the temperature in between those two temperatures.
Within the Degree Day System there are various aspects which when combined allow us to deliver fuel when necessary such as the K-Factor which is quite simply a number which shows us how fast a household uses fuel. As just as on a car you will see miles per-gallon of fuel use, the K-Factor shows us degree days per gallon. Another aspect is the Usable D.D. which tells us how many degree days can pass before we need to make the next delivery to you.
Obviously however there is also the Reserve which is equally as important as it is a safety reserve of fuel if necessary. All of these aspects combined in the Degree Day System enable us at Ingoe Oils to ensure we provide our customers with the best quality service we can provide.
