[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.
