RE: [EnergyPlus_Support] Question about plant loops and water heaters



1. Do plant loops simulate evaporation of the working fluid? i.e. water
to steam and vice versa?
 
Steam models do use fliud properties in the calculations.

2. If I wanted to run propylene glycol to heat water in a water heater,
can I simply use one plant loop for water heating and a second plant
loop for the glycol? OR would I need to add in a heat exchanger?

The water heater use and source nodes can model a HX. But as I write
this I wonder if a flud other than water is allowed to connect to the
use and/or source side of the water heater (it should be allowed, but
is it?).
