[Equest-users] Condensing Boiler Curves

[Brad Robinson]

Looking through the archive, I don't see much discussion on  condensing boiler curves.  Is there an example anywhere of how the variables for the Bi-quadratic in Ratio & T are calculated?  Independent-1 and Dependent seem to both be part load factors.  Independent-2 is the HWR temperature.  I have the efficiency's at various return temperatures and boiler load conditions, so I should be able to derive these values.  Thanks for any help.
