Abstract

A heating block for use in a water heater for heating water, having a heating block body, in particular made of plastic, for forming a cavity for conducting the water and for receiving at least one heating element. The heating block body includes a first partial shell having a first sub-cavity and a second partial shell having a second sub-cavity. The first and the second partial shells are assembled in a joining region and form between them the cavity from the two sub-cavities. The joining region is not formed, at least partially, in a joining plane and/or the first and the second partial shells are welded together by the supply of heat via a medium, in particular, an essentially abrasion-free and/or vibration-free welding process, and/or the first partial cavity has a greater depth than the second partial cavity or vice versa.
