18. A fan assembly as claimed in any of the preceding claims, wherein the interior passage extends about the heating means.

19. A fan assembly as claimed in any of the preceding claims, wherein the heating means partially defines the interior passage.

20. A fan assembly as claimed in any of the preceding claims, wherein at least part of the heating means is located downstream of the mouth.

21. A fan assembly as claimed in any of the preceding claims, wherein the heating means extends at least partially across the opening.

22. A fan assembly as claimed in any of the preceding claims, wherein the nozzle comprises an elongate annular nozzle.

23. A fan assembly as claimed in claim 22, wherein the heating means comprises a plurality of heaters located along opposing elongate surfaces of the nozzle.

24. A fan assembly as claimed in claim 23, wherein the plurality of heaters comprises a plurality of sets of cartridge heaters, each set of cartridge heaters being located along a respective side of the nozzle.

25. A fan assembly as claimed in any of claims 1 to 16, wherein the heating means is located at least partially within the interior passage of the nozzle.

26. A fan assembly as claimed in any of the preceding claims, wherein the nozzle comprises a surface located adjacent the mouth and over which the mouth is arranged to direct the air flow.

27. A fan assembly as claimed in claim 26, wherein the surface comprises a Coanda surface.

28. A fan assembly as claimed in claim 27, wherein the heating means comprises the Coanda surface.

29. A fan assembly as claimed in claim 27 or claim 28, wherein the nozzle comprises a diffuser surface located downstream from the Coanda surface.

30. A fan assembly as claimed in claim 29, wherein the heating means comprises the diffuser surface.

31.
