I am in the process of finishing my basement, about 800 sq ft consisting of a bedroom, bathroom, and rec room. There are three existing heating vents, one in the bedroom and two in the rec room. I am thinking of adding a vent in the bathroom and another in the rec room near a window. This is heating only, does it sound adequate? Do I need to add cold air returns? Perhaps one in the bedroom and a second in the rec room?
Thanks,
-John
