Abstract (en)
[origin: EP0405136A2] A pipe run (9, 10, 3) starting from a hot-water supply installation (6) ends at a switchable hot-water preparation installation (1), to which a tapping point (4) is directly connected. The water heating installation (1) is only switched on when water is tapped and at the same time the water temperature, for example detected by a thermostat (5), at the end of the pipe run (9, 10, 3) is not hot enough. The aim is immediate hot-water preparation irrespective of the respective degree of cooling of the water contained in the pipe run (9, 10, 3). <IMAGE>
