A heat recovery device is provided for recovering thermal energy from a fluid medium, in particular for use in a waste-water system of a dishwasher. The heat recovery device comprises at least one heat exchanger with at least one heat exchanger surface. The heat recovery device further comprises at least one heating device, which is thermally coupled to the heat exchanger surface, and also at least one controller. The controller is designed to carry out a self-cleaning process for the heat exchanger, with the heat exchanger surface being briefly heated by means of the heating device during the self-cleaning process. |
