A heated air circulating device 10 comprises a housing 12 defining an internal chamber provided with an inlet, through which air heated by the radiator enters the chamber, and an outlet, through which air is expelled from the chamber. The inlet includes a continuous slot 32 which extends along the full length of the housing. The device is preferably positioned above and at least partially behind a wall mounted radiator (40, fig.2) such that the slot locates above the area between the radiator and the wall (42, fig.2). In use, as the radiator heats up, warm air generated behind the radiator rises and passes through the slot and into the chamber, where since the slot extends for the full length of the housing the rising warm air is not restricted from entering through the slot. The device may include a fan 14 located towards one end which draws air along the chamber and expels the air out to the side. Preferably, the slot includes guide means which increases the pressure of the warm air as it passes through the slot and the pressure then falls once the air enters the chamber. In further aspects, the device comprises thermal sensor means. |
