Filip, 

When I run your closed feedwater heater specification in the latest
version of TRNSYS it runs without issue. May I ask what version of
TRNSYS you are using?

I use the Condensate Pump (Type 597), which can reach the outlet pressures of up to 230 bar and cannot reach the desired outlet presure of 250 bar. When the outlet pressure is set to 250 bar, I recieve the message that TRNExe.exe is not responding. I recieve the same message when I use Closed Feedwater Heater (Type 621) to heat condensate (t=180 C, p=200 bar, h=773,5 kJ/kg, m=970020 kg/hr) with superheated steam (t=500 C, p=20 bar, h=3468 kJ/kg).
