Heizkennlinie Calculator

Enter the "Neigung", "Raum-Solltemperatur" and "AußenTemperatur":


Max Puffer Temp:
Min Puffer Temp:

The equation we use to calculate the Vorlauftemperatur is a standard ansatz used for heat pumps:

TVor = Traum + α η (Traum - Tout)x

where TVor=Vorlauftemperature, Traum=Raum-Solltemperatur, Tout=AußenTemperatur, and η = neigung. The parameters α and x depend on the particular heat pump used. Note: we have chosen the offset N=0. For our Vießmann heat pump we use α=1.83 and x=0.83, which agrees fairly well with the graph below.
