[Equest-users] Condensing Boiler in DHW Loop

[Nick Caton]

Hi John,

This may get you started:

-          Create a HW Loop

-          Create a Condensing Boiler/Pump, attach to the new loop

-          Define a process load + schedule in the second tab of the loop to match your DHW consumption.  You may need to define the load with MBtu/h and not gpm.

-          As a result you should see your condensing DHW pop up in the consumption reports as a green process load on the gas side.

-          You might want to leave your normal DHW loop in operation while setting this up as a check to see that you're matching well before deleting.  Review the HW loop/boiler inputs carefully to ensure everything is appropriate to DOMHW.

Screengrabs follow to illustrate the concept:

Best of luck!

Subject: [Equest-users] Condensing Boiler in DHW Loop

Any suggestions as to how to make the DHW heater a condensing boiler ?? The Condensing feature is for a boiler , which wants a Hot Water loop, NOT a DHW loop..
