Abstract: The invention relates to a heating module comprising a resistive heating element placed in a frame. The heating module constitutes a ready heating subassembly for heating a gas or a liquid, in particular for heating the air. The heating element is mounted to the frame by means of the at least two contacts arranged at opposite side walls of the heating element, wherein each contact comprises at least two brackets releasably coupled to a side wall, and at least one resilient element connected to the brackets and to at least one catch releasably coupled to the frame, wherein each resilient element, arranged in contact with a side wall of the heat ing element, is tensioned and exerts an expanding force acting on the connection of the contact with the frame and the heating element.

Abstract: The heater characterized by the fact, that is being determined by at least one segment (1) which in side-view resembles letter “L” in upside-down position and each segment (1) is created from the housing, where heating element is fixed, at the same time the housing improvingly consists of parietal part (2) as well as upper part (3). Parietal part (2) of the housing comprises full partition, whereas the upper part (3) of the housing is equipped with slits (6, 7), improvingly rectangular in shape.

Abstract: The cover of the container has the hollow (2) with an elliptical outline pointed towards the inside of the container; the hollow has the spherical projection (3), pointed upwards, and the projection has the cylindrical cavity (4) with the opening housing the valve head. The valve head has the form of a circular plate and has an edge with a triangular outline; cooperating with the gasket of the valve. The head valve is installed loosely in the opening by means of the sleeve ending with the flange with distancing projections in the form of radial ribs.
