10.1 Template for Experimental Determination of the Actually Required
System Temperature
Fig. 10.1: Diagram for experimental determination of the actually required system temperature
Carry out the following steps during the heating
period at different external temperatures:
1. Step: Set the thermostats in rooms with high heat
consumption (e.g. bathroom and living room) to the
highest level (valve fully open!).
2. Step: Reduce the flow temperature at the boiler or at the
mixer valve until the desired room temperature of
approx. 20-22 °C is reached (note: take the
sluggishness of the heating system into
consideration!)
3. Step: Enter the flow and return temperatures and the
external temperature in the table.
4. Step: Transfer the measured values to the diagram.
Measured values
Example 1 2 3 4 5 6 7 8 9
External temperature -5 °C
Flow temperature 52 °C
Return temperature 42 °C
Temp. difference 10 °C
