Re: [EnergyPlus_Support] heat recovery by IC generator

["Michael J. Witte" <mjwitte@xxxxxxxx>]

It is difficult to guess what is happening without seeing the input file.  It 
appears that nothing is placing a load on the heat recovery loop.  So, the loop 
temeprature has risen to 100C during the simulation warmup days and the 
generator can no longer add heat to the loop, so it reports zero heat recovery. 
 Check the connections and the controls.  If you cannot solve the problem, 
please upload your input file (idf) to the yahoo group files area or send as a 
zipped attachment to energyplus-support@xxxxxxxx
