The heat exchanger for drain water has a water drying gutter (1) for the drain water, in which there is at least one heat exchange element (2) in direct contact with the drain water. This element has a circuit for a separate heat exchange medium. By this means, heat is taken via at least one heat-conducting exchange surface (20) from the drain water. This heat is transferred to the other heat exchange medium and is then taken by the circuit to a heat pump. |
