  • Page 12 Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Curve Inclination Primary Flow Temperature The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C.
  • Page 13 Heating Summer season Primary Flow Temperature switched off ºC All properties have internal heat gains (lamps, oven, Heating up body heat, etc.), which means that the heating can be switched off when the outdoor temperature is lower than the desired room temperature. The better insulated the house is, the earlier the heating from the heat pump can be switched off.
