[Equest-users] Multiple Heating Hot Water Loops

[Jeremy McClanathan]

eQuest allows you to create secondary loops with different design temperatures.  Right click on project, create a new circulation loop of type Hot Water, choose secondary subtype, select the primary loop and specify your design temperatures.  It will use a 3-way valve to mix down the temperature you specify.  There may be a couple steps I'm forgetting, but this is the general direction I head in.

How do you model multiple temperatures for various heating HW loops such as radiant slab (120/constant temp) vs. HW loop (160/based on OA reset) for any type system if they are all coming from the same boiler plant?

Do you provide a heat exchanger on the peripheral loop to account for the different temperature?
