RE: [EnergyPlus_Support] A great deal of problems with "Water Heater"

That error is a known issue that has already been fixed for the next
release.  It comes from mixing hard sizes with autosizes.  To get past
this error with version 2.1, you'll need to either hard size the water
heater connections or autosize the plant loop flow rates.  

 

This kind plant system for cogeneration should be working for the next
release, but with Version 2.1, it is going to be difficult and may not
work well.  For starters, the generator will need to be moved to the
demand side and the water heater source side to the loop's supply side.

Subject: [EnergyPlus_Support] A great deal of problems with "Water
Heater"

 

Hi, my name is Stefano and I'm working on EP for completing my Master 
Thesis in Mechanical Engineer, but I have some problems to simulate 
my house-plant!
I try to show you the plant:

|-----------[baseboard]--------------------------|
| | Use
| _________________ | Side
|-pump->----| |-----[boiler]-------|
| Water Heater |
|-----------|_______________|-[microCHP]-<-pump--|
| | Source
| | Side
|------------------------------------------------|

I try to simulate and EP found 2 errors:
1 - User entered Plant Sizing name for Use side does not match plant 
description in Water Heater: SERBATOIO (=in English is a "water tank")
2 - User entered Plant Sizing name for Source side does not match 
plant description in Water Heater: SERBATOIO
Now...I don't understand what they mean because there aren't fields 
called "Use side" and "Source side" in the "Plant Sizing" array.
How could I work this out?
I'm uploading the input file on the forum. The file name is 
"01 DEC 110308.idf".

Thanks a lot, bye!
Ste & Teo
