RE: [EnergyPlus_Support] Something about the water heater: mixed

Where in the I/O Ref does it say that?   Plant loops can also be connected to the Domestic Hot Water.  Stand alone won't work for this. 
 
It is difficult to give a full discription of how to do this in a text email.  But for this system you'll have to set up two PLANT LOOPS connected together by the Water Heater:Mixed object.   One loop for heat recovery will add heat to the Water Heater on its source side, the other loop for hot water will serve the coil and domestic water.  I would suggest studying the plant-related input objects in the example file  SolarCollectorFlatPlateWater.idf,  then swap out your IC engine for the solar panels. On the demand side of the hot water plant loop, use a splitter/mixer to put the hot water coil and the Dometic Hot Water on parallel branches .

Subject: [EnergyPlus_Support] Something about the water heater: mixed



	Dear all
	
	I am using a water heater to recover the heat from an IC engine. In the winter, the water 
	heater will supply hot water to the fan coil unit for heating.
	But I want the heater to supply domestic water during the summer rather than supply hot 
	water to the fan coil unit. How can set up the water heater for the purpose?
	Since the I/O reference says that only the stand-alone mode of the heater can supply the 
	domestic water, how can I make the heater use the exhausted heat from the engine?
	Thank you in advance.
