Our automatic oil delivery depends on a degree day system that helps us keep track of how cold it is and when you need an oil delivery.

Most homes start using their heating systems when the outside temperature falls below 65 degrees. A degree-day is the average number of degrees below 65 on a given day. For example, if the average temperature on Oct 1st is 55 degrees, we would say that 10 degree-days accumulated on October 1st (65-10). If the average temperature on Oct 2nd is 50 degrees, that would mean that 15 degree-days (65-50=15) accumulated on October 2nd. Add the degree days together (10 +15=25) and we see that 25 degree-days have accumulated since the start of October. If you do this for an entire season you will have a total of degree days. In Connecticut we accumulate close to 4,800 degree-days a year.

Depending on how high you set your thermostat or the size of your home the house will use a constant amount of oil for every degree day. Again depending on the size of the home, a large home might use one gallon for every two degree-days, a small house maybe using one gallon for every 10 degree-days. This is called “Consumption Factor”. In this case a small home may have a WKF of Ten and the larger home would have a WKF of two.

Once we’ve determined a home’s WKF. This is done after a couple of deliveries or the past history on your account, we project when we need to make a delivery. For example a house with a WKF of five that has a 275-gallon tank we try to deliver a tank when it is 1/3 full. We target a delivery of 180 gallons. Since we know the WKF is five and since we want to make a 180 gallon delivery, we know we should deliver oil to this house every 900 degree-days.
