A room heat circulation system for circulating warm air from the top of a room to the bottom of the room using a wall of the room as a duct. A do it yourself kit including a fan and upper grill connected to a housing is adapted to be inserted into an upper opening in the wall and a bottom grill is adapted to be inserted into a lower opening in the wall. The upper grill has upwardly directed louvers and the bottom grill has downwardly directed louvers for drawing in warm air from the top of the room by the fan and exhausting the warm air into the bottom of the room. Retractable and expandable connecting means are connected to the housing and the lower grill and operable from the front whereby each of the connecting means may be retracted for installing the units into the openings and then extended for engaging the edges of the opening.
