I have the need to model a loop in openstudio that will provide the heat to my VAV heat loop, the domestic hot water and the a baseboard radiator, via a U pipe heat exchanger. I have read here that there is no heat exchanger in E+ that can be operated with steam (causing errors in OpenStudio simulations), and I need to use a hot water boiler. Has this feature been included in any of the latest releases of E+?
