Just curious, is your chimney on the main or upper level?

1st (and only) floor.
I have a
fireplace in a basement rec-room, and have assumed heatloss wasn't too
bad,
since it is in a basement. Maybe I should re-think that.



You would if you saw this film moving around. Today is only mildly
breezy, and the film just never stops moving.

Tape a sheet of newspaper from the top edge & let it hang down across
the fireplace opening. I'd bet that newspaper never stops swaying around.

Damn you. You just made me add yet ANOTHER thing to my list of annoyances to
deal with! :-)
