How to model Domestic Hot Water loop (WaterHeater) with HB 1.8.1

How can one model Domestic Hot Water loop using HB?
In particular, I need to model the WaterHeater:Mixed object.

I tried to achieve that by using Service Hot Water system component, but it seems not doing anything (I can’t find the object name in the .idf file).

And this is the result I am looking for:

Hi @mrbro ,

You are assigning the SHW system correctly but the Generic Office Program that is assigned to your single-room model does not have any hot water usage associated with it. If you assign a program that has hot water demand like 2019::MidriseApartment::Apartment, you will get the hot water heater and loop in your OSM and IDF.
