This method is very similar to the Degree Day routing method, except the K Factor does not change.

How it works: Go to the Routing window for the tank and select the "Degree Days" routing method. Then enter the K-factor for this tank in the text box. The system will use this factor to calculate return dates. For an explanation of K-factors, left-click here.
If you're unfamiliar with the Gallons per Day routing method, see Gallons Per Day Routing Method.
How it works: This routing method uses a combination of both the Gallons Per Day and Static K-Factor to determine the next delivery date. For instance, this might be used if a customer has both a water heater (where usage is consistent and Gallons Per Day is the best way to estimate usage) and a heating appliance (where Degree Days is more appropriate).
