<p>The heater has connectors (7, 10) for hydraulic connection of a storage container (1) with a cold water inlet line and a hot water outlet line (8). An internal heat exchanger has partial heat exchangers (2, 3) connected in rows. The heat exchanger (3) e.g. helical tube, works based on principle of natural convection. The heat exchanger (2) e.g. plate-type heat exchanger, is arranged in the supply line after a connector (4), and woks based on principle of forced convection regarding secondary side heat transmission to drinking water.</p> |
