<p>A heat exchanger is designed for building-in in a floor (4) of a shower arrangement. Viewed in built-in operating condition, the heat exchanger (1) comprises:
- a drain trough (5) lying recessed in the floor for collecting waste water, which drain trough has a substantially horizontally extending trough longitudinal direction (L);
- a heat exchanging separation construction (7), via which heat transfer between the waste water and tap water takes place, and which is substantially located in a vertical projection space (8) of the drain trough, located under the drain trough, and extends in the projection space substantially both in the trough longitudinal direction and in vertical direction; and
- a waste water distributing construction (9) which, viewed in the built-in operating condition and in the sense of the flow of the waste water, is situated upstream of the separation construction and guides the waste water collected by the drain trough in a manner distributed in the trough longitudinal direction to the separation construction.</p> |
