I saw this post a while ago, and it may shed some light on your heat exchanger question:

[Bldg-sim] Boiler with heat recovery

Dear Group,

I have modeled an office building which is heated by boiler, however I would like to model the boiler with heat recovery for energy efficiency. I have investigated example files of energyplus but I couldn't find any examples for this type of boiler. Therefore I would like to learn if it's possible to model a boiler with heat recovery?

Ece,

What you are looking for is the WaterHeater:Mixed object. This boiler has four ports, one source side inlet and source side outlet for a heat recovery loop or solar hot water heating loop, and one use side inlet and outlet for the demand loop. There is also a heating coil of either natural gas or electric type in order to meet the heating demand when the source side heat transfer is inadequate to serve the load.

Hope this helps.

Dear members ,
i want to model a heat exchanger that one side of it is from hot water plant loop , and another side of heat exchager is from domostic water ,

could you please how i can model it?
i try to model it by using watreheater:mixed , and put tank volume fiels zero but i dont know what setpoint temperature schedule i must enter because my heat exchanger doesn have setpoint ,

Any help would be appreciated,
