Calculated flow rate
Temperature differential (primary circuit flow/
return) ΔT:
■ With secondary circuit flow temperature =
35 °C and primary circuit flow temperature
= 10 °C
■ With secondary circuit flow temperature =
35 °C and primary circuit flow temperature
= 0 °C
Testing the mixer, heat pump and cylinder heating
Checked under the following conditions:
Room temperature
Outside temperature
Temperature "Cylinder temp. top" constant?
