FIELD: instrument engineering.
SUBSTANCE: present invention relates to a device comprising main tank (4) for containing water and intermediate tank (7), configured to supply water from said main tank (4) to it, while intermediate tank (7) contains cathode (10) and anode (11; 211) for the precipitation of calcium carbonate, as well as the filter (8), which forms the filter septum, separating the internal volume of intermediate tank (7) into primary chamber (71) accommodating cathode (10), which is adapted to supply water from main tank (4) into it, and includes secondary anode (11; 211) chamber (72), which accommodates the extraction of water from it for use in device (5), and anode (11; 211) has two longitudinal ends (11A, 11B; 211A, 211B), between which it passes in the longitudinal direction along the X axis, characterized in that it is possible to take water from secondary chamber (72) at the level of at least one intake opening (92; 92A, 92B; 292), located in the projection orthogonal to the X-axis between two ends (11A, 11B; 211A, 211B) of the anode.
EFFECT: present invention relates to a device comprising a main tank for containing water and an intermediate tank configured to supply water from said main tank.
