<p>The invention relates to a water heating module and to an installation comprising the same, intended for the preparation of heating medium and/or household water. According to the invention, the module comprises a tank (1) wherein an internal cylindrical electrode and an external helical electrode (2 and 3), respectively, are centrally and axially located, respectively, with a functional gap therebetween, which are connected to an upper rod (4), the external electrode (3) being in connection with a lower rod (5), both rods (4 and 5) having electrical conduction properties and being connected to a transformer (6) belonging to a power supply subassembly (A), a temperature sensor (9) being placed in a lateral cylindrical wall (a) of the tank (1) and an adjustable overpressure valve (10) being mounted in an upper wall (b) of the tank (1). The installation, as claimed by the invention, comprises at least two water heating modules (B) which are serially connected by means of a hot water delivery pipe and a cold water supply pipe (11 and 12), respectively, each module (B) providing water heating while allowing temperature regulation depending on information received from a microcontroller (77) for the operation of the subassembly (A) which is in connection with the motor of a pump (13), where each subassembly (A) is placed within a general panel ( C) which also ensures the power supply of the pump (13) and of a temperature and pressure selection module (87) which comprises an AC transformer (93) connected to an electric network of 220 V.</p> |
