Abstract
An object of the present invention is to provide a hot air space heater that is capable of blowing hot air out of a whole wide hot air outlet provided at a front plate of a frame of the heater while making the heater smaller in depth. A burner is arranged so as to be close to one side of the frame. A heat-discharge portion is constructed on the burner. On the other side of the frame, an accessory-receiving space is defined side by side with the heat-discharge portion. Between the hot air outlet provided at the front plate of the frame and a wall portion positioned in front of the accessory-receiving space, an extended air feed space is defined. Air fed by a fan into a duct structure is heated while passing through between a plurality of heat-exchange pipes. The air is blown against a front wall of the duct structure and a plate-like member of an air guide provided on a rear side of louvers. Heated air blown against the front wall flows out forward through a first air flow path above the plate-like member. Heated air blown against the plate-like member is guided into the extended air feed space and flows out forward through the louvers.
