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 ( ) surrounds at least the cylindrical wall part ( ) 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 millibar, corresponding to a vacuum of less than 0.0075 torr, such that the heat loss per unit area of surface area to be insulated is not more than 200 watts per square meter.
