Abstract (en)
[origin: DE19824034A1] A heating system for non-drinking water has a heat-exchanger (1), the primary part (2) of which is supplied with a heat transfer medium and the secondary part (6) of which is connected to a circulation pipe (9). The circulation pipe comprises at least one draw-off point (12) for hot non-drinking water, a circulation pump (13) and a cold water in-feed (15). A control device (19) comprises a first temperature sensor (20) at the initial section (10) of the circulation pipe (9) and a primary-side adjustment means (motorized valve 23), influenced by the temperature sensor, for the amount of heat transfer medium to be let through. A second temperature sensor (21), which influences the adjustment means, is arranged at the end section (17) of the circulation pipe (9) downstream of the cold water in-feed (15). In particular, the second temperature sensor (21) is a significant distance (a) from the heat exchanger inlet (8). The temperature of the non-drinking water is therefore subject to fewer fluctuations.
