David,
It looks like you will have to make a boiler to approximate the district hot water loop.
Some suggestions:
1. Make boiler efficiency equal to 1
2. Remove any auxiliary equipment and start-up/shut-down time
3. Assign a separate fuel meter to it with the associated district hot water cost per unit of energy (perhaps MMBTU, M=1,000) rate structure
This is similar to how you do this in TRACE as well, if anyone was wondering.

Hello All,
I have a project with water loop heat pump system and district hot water as heating source. Different from regular configuration of boiler, I have trouble getting the district hot water loop into the water loop heat pump in DOE2.2. Does anyone have any idea how do I configure the loops?
Any suggestion is appreciated. Thank you,
David
