[EnergyPlus_Support] Condensing boiler curve question
The EnergyPlus installation includes the Boilers.idf file in the
Datasets directory. This file includes a Biquadratic, condensing
boiler curve. What isn’t clear is if this curve is based on the boiler
Entering or Leaving temperature.
The reference for this curve is from Viessmann and all the Viessmann
condensing boiler literature I have reviewed states the boiler
efficiency is dependent on system heating water return temperature.
Should I specify Entering or Leaving when using this curve?
Thanks for your assistance!
