Degree Days Routing Method


Degree Days Routing Method

If you are unsure what a degree day is, please see Overview of Degree Days.

If you choose this routing method (and at least four deliveries have been made to the tank) the system will automatically calculate the Gallons Per Degree Day to project the next return date.

Note: Accurately using the Degree Day method requires that you maintain the degree day file for your location each day. For help on how to do this, go to Update Degree Day Information.

What if you don't have enough history?

If you want to use the Degree Day method but do not have sufficient history for the tank (at least four deliveries), you can use any one of these different approaches listed below. When you finally do get four deliveries, each of these approaches will automatically revert to using the actual delivery information and Degree Days to calculate the return dates.
