摘要

The device has a plate heat exchanger (1) arranged at an exterior side of a distribution tank (2), where the device produces the sanitary hot water by using the plate heat exchanger and heats the sanitary hot water in the distribution tank having capacities of 200, 300 or 500 liters. A daily time indicator is manually programmed with an operating time slot based on seasons. A primary solar circuit (6) drains the sanitary hot water from a retaining beaker (3) when the device is turned off.
