[EnergyPlus_Support] Hot Water Loop Temperatures



When I add internal gains to may model, (which as a chilled and a hot 
water loop, served by chiller and boiler, respectively), the 
Temperatures at the inlet and outlet of the hot water loop (and 
boiler), in a summer week, when the boiler is off (I checked!) start 
rising steadily, well above the nominal boiler temperature and the zone 
temperatures (even those of the uncontrolled zones).
NO similar effect occurs in the chilled water loop, nor in the winter 
nor in the summer.
I can't see the relationship behind this effect and I'm worried it 
reveals some problem with the modelling.
Can anyone help me?

Thank you,
Ana Rui
