A steam generator for a wallpaper stripper includes a member of heat conductive metal in which is cast an electrical heating element of generally W-shape. Water is supplied to an inlet chamber in the member. Leading from the chamber to spaced steam outlets in the member is a series of extended passageways formed by channels between adjacent limbs of the element and ribs that extend both along and across the channels. The nozzles are located in walls.

A steam generator, comprising: a body of heat conductive material, the body being recessed to form a chamber; an electric heating element located within the chamber and having a series of spaced, parallel limbs embedded in spaced, raised parts of the floor of the chamber to form channels between adjacent raised parts; barriers dividing up some at least of the channels into separate sections and allowing communication between the sections via passages which pass over the raised parts; a water inlet chamber located between the adjacent raised parts and in communication with the passages; a plurality of steam outlets also in communication with the passages; the steam outlets being nozzles whose entrances are located above the floor of the chamber; the body being recessed at one end to form a recess and a thermally responsive element being located in the recess; and the recess having an inner wall with an opening through which is exposed a part of the heating element.
