Make heat pump model with hot gas heat exchanger #1621

Several new heat pumps are having hot gas heat exchangers to provide hot water in parallel with room heating with high efficiency. However there is no heat pump model in the Building library that can model this functionality of modern heat pumps.

Do you have good literature that shows how such a model could be implemented without having to model the refrigerant cycle, which would computationally be expensive and rather be avoided if not needed.
