[Equest-users] Replacing baseboard with heat pump results in higher space heating

Yes, it is rough.  Where does one begin?  I generally like to look at 
the results in the .SIM file.  First look at the SV-A reports - one 
model has no outside air, the other has 10000 cfm outdoor air.

Then look at the SS-D report.  The one has a peak heating of 339 
KBTU/hr and the other has 1200 KBTU/hr.   This could be due to adding 
outdoor air to the other.

If I still don't have an inkling, I will add some hourly reports to 
compare the total supply cfm vs outdoor air ratio at different hours 
of the year.  I didn't have to do that in this case.

And if all else fails, I would then ask for help from the egroup.
