A temperature sensor (4) and a timer are provided for controlling the solar charge pump at the solar panel in the hot water outlet. The solar charge pump turns off after a preset of its running time and the temperature change is determined by the temperature sensor. The solar charge pump is operated by the temperature rise and remains switched off by the temperature drop.</p> |
