A heating fan has a fastening means for fastening of said fan to a first surface. A stem connects the fastening means to a hub. The hub has a motor unit. The motor unit rotates a plurality of wings extending radially from said hub. The wings have upper and lower surfaces. Each wing has a leading edge and a trailing edge, defining upper and lower surfaces therebetween. At least one wing has electrical heating means integrated or connected to the upper surface. At least more than half the length of the leading and/or trailing edge is bent downwards relative to the surface of the wing. |
