We just put a 12x18 room off of the living room with a 14' cathederal ceiling. I had planned to run two 8" round ducts from the furnace/ac in the basement, in the floor joists in the addition, and come up/out of the floor about 6" from the far wall. This would send the air straight up from the floor in front of about a 12'x12' area of windows.

The question is this: Someone pointed out to me that I really should be using 2¬Ω" x 14" baseboard vents rather than floor vents. I agree in the sense that floor vents tend to catch a lot of dirt over the years, but I was wondering about the issue of sending the air up versus out into the room. Maybe it's not really an issue.

Summers are in the 80's but rarely hit 90. Winters are long and cold. Usually in the 20's. The wall of 12x12 windows on the side of the addition where the vents will be, faces the sun, meaning that we will get some (good) heat value from a sunny day in the winter, but the potential for a cold room as we don't get much sun in the winter. As for the summer, the AC would be cooling the room.

We have a 52" ceiling fan as well.

So. Vents, straight up .vs vents mounted on the baseboard that blow straight out....

Hmmmm......

Thanks

Thanks for the excellent comments on the situation. As a result, I rushed home during lunch to instruct the contractor to install the vents in the floor, like I had originally planned. To me, it makes total sense to direct the air flow upward to kill any window drafts and then use the ceiling fan to help temper the mixed air. Good thinking. Also, in the summer months, it will serve to blow the cold air straight up as well, again, mixing with the warm air and using the ceiling fan.

Much appreciated!

So the choice is a "chill", versus "breezy" (from your first post)? I'm wondering now if I made the right choice...Seems like "breezy" might be better?
