Are there heater vents that can open and close as the air passes through them; this way being closed when off so the warm air won't escape back into the vent. My heater is located outside meaning the vent being always open is a straight line out.

Automatic dampers exist that could be installed on the vent at the HVAC, but you'll have to find one that isn't wired to default to open. – BMitch♦ Jan 24 '12 at 11:27
