De-humifiers work on the principle of cooling heat exchange fins, blowing air
through them to condense water from the humid air.  For every BTU of cool air
out the front (or rear depending upon your model) there is an equal amount of
hot air out the other end.  A small additional amount of hot air is made to
equal the compressors inefficiency.  If the unit is old, low on freon or the
condensing coils are dirty, the unit will make more heat than it should.  On
_balance_, the unit might not be making that much heat ... unless it is
faulty (hmmm 3 years old? ... bet it is OK).
Perhaps, I should have said warmer (in the winter) than the outside ... since
the ground is in the mid 50's and that heat is going to help warm the
basement up from the below zero outside.  I'd rather heat my basement than
the upstairs, more efficent.  Suspect the same is true for yours.
Sheese, I'd find some other way of heating your bird room than using electric
heat.  $$$$. Can't you duct upstairs heat ducts to them?  The air return
would need to be filtered or you would get more bird dust upstairs. I use an
electric heater as a backup to our gas furnace in the basement.  This is to
prevent pipes freezing in the event the pilot goes out while we are away, the
bird room is the first beneficiary of this heat insurance.
BTW, we have a 'Florida' type of sun room full of mostly tropical plants.
Exposed on 3 sides on a concrete pad, attached to our home.  It is warm in
the winter ... sometimes even warmer than the upstairs bedrooms ... when the
sun is out.  In summer it is at times too warm for Zonker.  She has been
spending the last 2 weeks in our living room ... also good for a change of
habit for her as well as heat avoidance.
