The water heater () or steam generator comprises a chamber () in two sections () formed in particular by stamping. Inside this chamber a heating element () is arranged, which has a spiral-shaped main section () and two end sections () passing through two circular openings of the chamber. The two end sections are welded to the chamber by a laser beam such that the weld obtained is continuous and ensures a good mechanical fixture of the heating element and an adequate tightness for the water heater or steam generator. For this purpose, a flange () is arranged at the periphery of each opening. Moreover, the two sections of the chamber have a widened edge () to allow them to be welded effectively.
