本发明涉及提供温水，特别是热水，与包括至少一个热发生器和至少用于循环流体的第一泵的热水处理植物的方法，特别是水，第二次在至少一个主电路和至少一个热水箱和至少一个 泵用于循环流体，特别是水，特别是饮用水，包括在至少一个次级电路，其中至少一个热交换器设置发热体和所述热水箱之间。 与第一泵，所述流体通过所述热交换器（28）的初级侧泵送。 与所述第二泵，所述流体通过所述热水箱和通过热交换器的二次侧泵送。 此外，所述至少一个泵的旋转速度被限制。 所以建议温度的实际值是在所述热交换器的二次侧输出被检测到，该限定的热水存储目标值的热水贮存箱的温度或计算中考虑的控制策略。 接着，将至少一个可控制泵的速度被控制基于在这样的方式的控制策略中，提出的是，实际的值高于或等于所述热水箱的设定点，其中，所述至少一个泵，如果需要以减小的速度进行操作。 本发明还涉及一种系统，用于提供其中上述方法运行温水和用于此目的的热发生器。

The invention relates to a method of providing warm water, especially hot water, with a hot-water treatment plant comprising at least one heat generator and at least a first pump for circulating a fluid, in particular water, second in at least one primary circuit and at least one hot water tank and at least one pump for circulating a fluid, in particular water, in particular drinking water, comprising in at least one secondary circuit, wherein at least one heat exchanger is arranged between the heat generator and the hot water tank. With the first pump, the fluid is pumped through a primary side of the heat exchanger (28). With the second pump, the fluid is pumped through the hot water tank and through a secondary side of the heat exchanger. Further, the rotational speed of the at least one pump is regulated. It is proposed that an actual value of the temperature is detected at the secondary side output of the heat exchanger, and is that defined a hot water storage target value for a temperature of the hot water storage tank or calculated in consideration of a control strategy. Next, the speed of the at least one controllable pump is controlled based on the control strategy in such a manner, it is proposed that the actual value is higher or equal to the hot water tank setpoint, wherein the at least one pump, if necessary at reduced speed is operated. The invention further relates to a system for providing warm water in which the above process is running and a heat generator for this purpose.
