Choose a fan that will best address your needs. There are many types available from large and small plug-in fans, room-to-room doorway fans and even fans that are made to rest on top of a pellet stove that use no electricity.
Place the fan where you want the heat circulated. A non-electric pellet stove fan will blow hot air directly off the top of a burning pellet stove and provide whole room heating. A desk or floor fan will blow heated air from one room to another. A room-to-room doorway fan gets attached near the top of the door jamb and blows heated air unobtrusively into any room it is pointed at.
Turn the fan on and direct the airflow to the room or rooms where you want heated air circulation. A ceiling fan works much the same way. Since hot air rises, by blowing the air downward, you will achieve total warm airflow circulation in that particular room.
