alt Hacker NewsMy dad and his father built the house my family grew up in. The fireplace had two vents on either side of the fire box that drew air from the floor and vented near the ceiling. The ceiling fans in the room would circulate the air in the room. It was the only place I've spent time that a fireplace actually was useful.
When those work well they're fine but be very careful. It's not uncommon of for smoke to go out what you think is the in intake and often those aren't correctly built as a chimney and so you can burn your house down.
