Ron: I haven't found a way to deal with that at all. I can tell you that DW makes a significant difference in demands compared to HW at low temps.

Since we deal in GPM have you found a way to account for the gradual dilution of the solution for the first minute of flow or isn't that a factor?

Does anyone have a copy of that article they can send, or at least post the formula to adjust the k-factor? I have found out that hydratec does not automatically perform this adjustment. Thanks for your help.
