The cylinder (1) has a cold water inlet (3) at the bottom, an outlet (4) at the top, and an inlet (5) at the side for the return of circulated water. The side inlet is connected to an auxiliary chamber (7) inside the cylinder, designed to maintain an appropriate water temperature inside the cylinder when no hot water is being used. The auxiliary cylinder is elongated in form and situated vertically. Its walls are formed by a sector of the cylinder wall, and an additional partition (8) which is fixed to it and has holes for the passage of returned water. It can also be open at one of its two ends (11,12). During operation the circulated water returned to the cylinder is distributed in layers by the auxiliary chamber, so that the water in the cylinder remains in its appropriate temperature layers. ADVANTAGE - Maintains supply of hot water by preserving temperature layers inside cylinder.
