A heating apparatus for a liquid includes a vessel (1) having a base and a side walls (2, 3), and a planar electrical element (5) integrated in the base wall (2). In order to render the apparatus efficient when only a small quantity liquid is to be heated, the base wall (2) of the vessel (1) surrounding the element (5) is inclined towards the element (5) so that the liquid retained in the vessel (1) is directed on to the element (5). Preferably, the portion of the base wall (2) of the vessel (1) surrounding the element includes a lip (9) whereby the element (5) is stepped downwardly from the base wall (2) to form a well whereby a small quantity of liquid is retained either in direct contact with or directly above the element (5). The angle ( alpha ) of inclination of the base wall (2) of the vessel (1) to the element (5) is preferably at least 5 DEG .
