<DIV><SPAN class=074081120-27042010><FONT face=Arial size=2>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?</FONT></SPAN></DIV>
