SolarVenti blows new air in. Where does the air come out again?
The air will automatically be drawn to the places where it is easiest to get out, e.g. to vents in kitchens and bathrooms or other vents and openings in the house. If possible, let the air blow directly into the most important room and open the doors to other rooms. You should be aware that a chimney damper in a chimney which is not in use will create an outlet for the air in the room.
