Missing DHW loads

1 post / 0 new


I need a bit of help.

I input my Proposed Building first which used traditional split systems.

I then did a "Save As" and started changing things to get my 90.1
Baseline building.

After I added the central boiler for heating and changed my systems to
PTACs, my DHW usage went to Zero. The only thing I changed with the DHW
system was the efficiency.

Any clues as to what happened?
