A heating device (1) which includes: an assembly (2-4) made of a heat-conducting material and has a heating resistor (5) and has a defined passage (7a, 7b) close to the resistor (5), for a flow of water to be heated. The assembly (2-4) includes a central body (2) having two main opposite surfaces (2
A heating device (1) which includes: an assembly (2-4) made of a heat-conducting material and has a heating resistor (5) and has a defined passage (7a, 7b) close to the resistor (5), for a flow of water to be heated. The assembly (2-4) includes a central body (2) having two main opposite surfaces (2a, 2b) to which respective closing shells (3, 4) are connected in a liquid-tight manner. Between each main surface (2a, 2b) and the associated shell (3, 4) there is defined a passage following a serpentine path (7a, 7b). The serpentine passages (7a, 7b) communicate with each other by a through-hole (10) provided between the main surfaces (2a, 2b) of the central body (2). The heating resistor (5) is provided in the central body (2), between the main surfaces or faces (2a, 2b) such that it is in a heat-exchanging relationship with both the serpentine passages (7a, 7b).

1. Electric heating device (1) for the production of hot water and/or steam, comprising: an assembly (2-4) which is made of a heat-conducting material and has at least one associated heating resistor (5) and in which, between inlet and outlet orifices (12), there is defined a passage (7a, 7b) which
1. Electric heating device (1) for the production of hot water and/or steam, comprising: an assembly (2-4) which is made of a heat-conducting material and has at least one associated heating resistor (5) and in which, between inlet and outlet orifices (12), there is defined a passage (7a, 7b) which follows a predetermined path, close to said resistor (5), for a flow of water intended to be heated and/or converted at least in part into steam;wherein said assembly (2-4) comprises:a central body (2) having two main opposite surfaces (2a, 2b) to which respective closing shells (3, 4) are connected in a liquid-tight manner;between each main surface (2a, 2b) of the central body (2) and the associated shell (3, 4) there being defined a respective passages which follows serpentine paths (7a, 7b);said serpentine paths (7a, 7b) communicating with each other by means of a through-hole (10) provided between said main surfaces (2a, 2b) of the central body (2);said heating resistor (5) being provided in the central body (2), between said main surfaces (2a, 2b), such that it is in a heat-exchanging relationship with both said serpentine paths (7a, 7b); andwherein the surface of each shell (3, 4) to be applied in a liquid-tight manner against a corresponding main surface (2a, 2b) of the central body (2) has a convex profile. 2. Heating device according to claim 1, wherein each of said serpentine paths (7a, 7b) comprises a groove (7a, 7b) with a channel-like cross-section provided in a main surface or face (2a, 2b) of the central body (2), said cross-section being transversely closed in a liquid-tight manner by a portion of the associated shell (3, 4). 3. Heating device according to claim 1, wherein said inlet and outlet orifices (12) are provided in the lateral surface (2c) of the central body (2). 4. Heating device according to claim 1, wherein at least one of said inlet and outlet orifices (12) is provided in the aforementioned closing shells or covers (3, 4). 5. Heating device according to claim 1, wherein the central body (2) and said shells (3, 4) are made of metallic material including aluminium or alloys thereof, and their surfaces configured to come into contact with water are provided with a coating including a ceramic material. 6. Heating device according to claim 1, wherein on each main surface or face (2a, 2b) the central body (2) has at least one positioning and centring formation (13) cooperating with a corresponding formation (14) of the associated closing shell (3, 4). 7. Heating device according to claim 6, wherein the positioning and centring formations (13) of the central body (2) are plastically deformed onto the corresponding closing shells (3, 4) such as to clamp and fasten said shells (3, 4) against the central body (2). 8. Heating device according to claim 1, wherein the central body (2) comprises two superimposed parts, and the heating resistor (5) is a resistor comprising a silkscreen-printed resistive material, following a serpentine, on one face of one part (2x) of the central body (2) facing the other part of said central body (2).
