Abstract: The invention provides a device (200, 300, 400) for heating a continuous flow fluid. Said device (200, 300, 400) consists of a steel conduit (3, 3′, 3″) through which the fluid to be heated flows and of at least one sheathed resistor (2, 2c, 2d, 2e, 2f) that is parallel to the steel conduit (3, 3′, 3″) and that is in thermal contact therewith. The steel conduit (3, 3′, 3″) and the at least one heating element (2, 2c, 2d, 2e, 2f) are incorporated in a die-casting element made of an aluminium alloy.
