Low Temperature Radiant tubing length

Hello everyone,

I am modeling a ZoneHVAC:LowTemperatureRadiant:VariableFlow, using the CFD algorithm. I have noticed that when I change the tubing length that does not show any significant effect on the air inside temperature. A 40m tubing length has the same effect as a 1m tubing length. Also when I change the circuit length I have the same results. May I know why is that happening?.Since changing the tube length should effect the temperature inside the room. And what is the different between the tubing length and the circuit length?

Thank you
