Ironbug: Primary/Secondary hydronic loops?

@MingboPeng…lots of questions today…thanks for your help as always!

what connections would I need to do in order to do a Primary/Secondary Chilled Water Loop? I tried connecting a CW Loop to the “Supply” node of another CW Loop but got an error. Any insight would be great! thanks!

You will need a “Fluid Heat Exchanger” to connect first loop’s supply side to the second loops’ demand side. Something like this?

awesome…and then connect BOTH CWLoops to the HVACSystem Plant Loops?

Right, both loops need to be connected to HVACSystem
