Re: [EnergyPlus_Support] Re: Connection hot storage to absorption chiller



Change the boiler object in the example I made 
(IndirectAbsorptionChiller_HotWater) to a WaterHeater:Mixed object. This 
object has auxiliary connections (source nodes) where you can connect 
the solar collectors. The nodes where the boiler is connected in the 
loop should be connected to the use nodes of the WaterHeater:Mixed object.
