[Equest-users] PVVT vs. PSZ

[Nicholas Couture, LEED AP]

Hello,
 
I'm comparing a PVVT against PSZ systems in the DD wizard mode.  On the
heating side I'm keeping everything the same, that is furnaces at 80%
AFUE and baseboard, all heating settings including the boilers are set
up the same.  I'm getting more fuel use for the PVVT system than the PSZ
system.  Can anyone explain why that is?
 
thanks,
