The tube (7) surrounding the heating element (13) is connected secured to the inside (5a) of the container base (5). The heating element is arranged so that it can be withdrawn from the tube (7), and in the tube is surrounded by an exchangeable electrically insulating heat storage medium (19). The container base (5) has a screwed connection (5b), to which the heating element is fixed across a screwed connection. The opening (5c) in the container base for the heating element (13) is designed for its frictional contact plug connection (15a). ADVANTAGE - Heating element and heat storage medium are fitted at container base so that they can be removed without any loss of liquid.
