Abstract: A hot-water appliance capable of resisting at least the pressure of the public water supply system, comprising at least one hot-water vessel with a supply conduit connectable to the public water supply system and a discharge conduit connectable to a draw-off tap, wherein the hot-water vessel further comprises a substantially cylindrical jacket wall and two end walls, characterized in that a vacuum insulated jacket (2) surrounds at least the cylindrical wall part (1a, 9) of the hot water vessel, with said vacuum insulated jacket consisting of wall(s) composed of a solid non-plastic material composition and a thickness of less than ca. 2 cm, the wall(s) enclosing a hollow vacuum space whereupon at a temperature difference between the hot water vessel and the ambient atmosphere of at least 90° C. the vacuum insulated jacket will retain an internal absolute pressure in the vacuum space of less than 10−2 millibar, corresponding to a vacuum of less than 0.

Abstract: A water tap for the purpose of dispensing hot water intended for arrangement on a horizontal face (3), comprising a shut-off cock (8) which is connectable, by an inlet (8a) thereof, to a hot-water source and connected, by an outlet thereof and via a water supply (12), to a pivotable discharge (2), of which discharge in inlet side comprises a straight length of tubing (5), the straight length of tubing (5) being clampingly arranged in a guide (1a, 1b, 16) of a tube guide housing (1) so that the discharge (2) is adjustable in the direction of the longitudinal center line of the straight length of tubing (5) and retains this position in any adjusting position under the influence of the clamping guide (1a, 1b, 16).
