adding a vent to homes forced air system

[nonhog]

Have a 1700 sq ft home and in the middle is a 15x15 unheated atrium.
My furnance is 110,000 BTU propane furnace. Any reason I should not add a
heater vent to the atrium?
Its got very high ceiling (all glass skylights 15x15) so it wont be real effective but should help right?
Being a smaller house the 110,000 should have no issues throwing out heat while adding another vent (or 2?)

My thought is the furnace has no idea where its "forcing" heat. It just goes till the thermostat says stop. Right?

thoughts?

I would check temp at the ceiling. Since hot air rises it's probably got plenty of heat up at 15 foot but needs a ceiling fan to get the heat down where you can feel it. That would make the most sense.

Depending on your ducting, adding vents may cut down on heat supplied to other rooms on the same duct line. Check with a HVAC specialist to ensure the additional vent(s) won't negatively affect your entire system.

Adding another vent IS going to reduce the airflow somewhere else. Is there a particular issue you're trying to 'fix' by doing this?
