GetSpecificHeatGlycol: Temperature is out of range error with loops when there's no glycol in the loop

savecancel

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 $^o C$, 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 posts here and here and here.
