I believe 1 / % boiler efficiency is the Heating EIR. So go to your
boiler tab on the Component tree when in the Water Side Module and input
the new Heating EIR.
I believe there are Condensing Boiler Curves in one of the BLDG-SIM
threads to also add to this. And I believe that under DOE2 HELP, there
is some discussion on such curves as well.
Good luck !!

Subject: [Bldg-sim] how to vary dDHW efficiency
I entered my model in the wizard and defined peak DHW use for this hotel
as a btu/sf value that EQUEST assigns a part load curve to.
Now I'm in the Detailed Editor and want to show a 98% condensing hot
water heater and differentiate from my base case generated at 80%
efficiency. Where do I get to assign these differing efficiencies?
Thanks in advance for any assistance!
