[EnergyPlus_Support] Water flow issue

["aymericnovel" <aymericnovel@xxxxxxxxx>]

Hi,

I am still working on my model using the WATERHEATER:MIXED as a 
connection to the hot water loop for my DX:COIL:HEATPUMPWATERHEATER 
object.

I have a problem of water flow rate that I cannot figure out!

Before there was a boiler and the installation was working perfectly 
as a varying water flow rate type, ie nothing in the bypass on the 
demand side.
Now, since I connected the water tank instead, I still have a 
variable speed pump and I have the same water flow and temperature 
going at the coils level BUT the water flow remains constant at the 
maximum allowed! As a result I have a lot of useless water flowing 
through the demand side bypass, which is not what I seek at all.

Does anyone have an idea why the water flow rate is constant? I 
didn't find anything on the WATERHEATER:MIXED definition that says it 
is operating only in constant flow mode...

Thank you very much for your help
Regards
Aymeric
