How do I model a Multifamily Central Heat Pump Water Heating (CHPWH) system?

You can review two sample files we provide, the Multifamily Example.bld, we also provide a file  Multfamily Electric.bld Both are modeled at the Plant level of the tree, Domestic Hot Water tab.  The inputs for the CHPWH are at the bottom section of the input screen, you can choose the type of Heat Pump, quantities, etc, as well as tank volumes, and supplemental loop capacities, tank locations and locations of condensers.  The water heater input at the top of the screen is used to supply Nonresidential spaces.  You CANNOT assign those spaces to the CHPWH, CBECC does not allow for that circumstance, so you will have to assign those spaces to a standalone WH.  Create a dummy electric WH if necessary.
