<p>The heated air circulating device 10 comprises a housing 12 defining a chamber therein. The lower face of the housing provides a slot 32 which extends for the full length of the housing 12. In use, the device is positioned above and at least partially behind a wall mounted radiator 40 such that the slot 32 locates above the area between the radiator 40 and the wall 42. As the radiator 40 heats up, warm air is generated behind the radiator 40 which rises and passes through the slot 32 and into the chamber. The device 10 includes a fan 14 located towards one end which draws air along the chamber and expels the air out to the side. Since the slot 32 extends for the full length of the housing the rising warm air is not restricted from entering through the slot 32. In addition, the slot 32 includes guide means which increases the pressure of the warm air as it passes through the slot 32 and the pressure then falls once the air enters the chamber. This thereby draws the warm air upwardly and significantly increases the efficiency of the heated air circulating device 10.
