Hi Jean,I see that you've also asked this question on Unmet Hours, so I'll cross-post my answer to this email thread for everyone's reference. If you're asking specifically why the term "GetSpecificHeatGlycol" appears in this warning message, that is because the GetSpecificHeatGlycol algorithm in EnergyPlus is called to check the fluid properties for ANY plant loop where a liquid circulates -- even if that loop doesn't contain glycol. You can see this reflected in your warning line:* Warning * GetSpecificHeatGlycol: Temperature is out of range (too high) for fluid [WATER]
You can see the EnergyPlus source code where this algorithm is defined here. In your case, a water plant loop is experiencing a temperature of 125 C, which is above water's boiling temperature. This could be happening during no- or low-flow periods, and you can read more about this in other Unmet Hours posts here and here and here.Regards,AaronOn Fri, Oct 23, 2020 at 3:35 AM Jim Dirkes Jim@xxxxxxxxx [EnergyPlus_Support] <EnergyPlus_Support@xxxxxxxxxxxxxxx> wrote:Â
If you actually want a 125C setpoint, that could be the reason for the error. Water doesn't do well above 100C ð???
On the other hand, the typical reason for getting a temp out of bounds error (in my experience) is some other problem with my input.

Subject: [EnergyPlus_Support] No Glycol Loop gets GetSpecificHeatGlycol: Temperature is out of rangeÂÂHi Guys,Does anybody get this error with loops when there's no glycol in the loop? ** Warning ** GetSpecificHeatGlycol: Temperature is out of range (too high) for fluid [WATER] specific heat **
  **  ~~~  ** ..Called From:PlantLoopSolver::EvaluateLoopSetPointLoad,Temperature=[125.00], supplied data range=[0.00,125.00]
  **  ~~~  **  Environment=KEITHSTRASSE (2O-12:26-12), at Simulation time=12/20 00:00 - 00:10Best regards,Jean
