The appliance, in particular a coffee machine, comprises three boilers (1, 2, 3). In addition a heating element (10, 11, 12) is disposed in each boiler, which element can be switched on and off through one switching means each (20, 21, 22) which are provided in a control mechanism (16).

The appliance, in particular a coffee machine, comprises three boilers (1, 2, 3). In addition a heating element (10, 11, 12) is disposed in each boiler, which element can be switched on and off through one switching means each (20, 21, 22) which are provided in a control mechanism (16). In each of the boilers moreover there is one temperature sensor (13, 14, 15) to measure the temperature of the hot water. The control mechanism (16) has in addition computational means (17) as well as memory means (18, 19). Among other things predetermined desired temperatures for the water in the individual boilers as well as the maximum available power supply of the coffee machine can be stored in the memory means (18, 19). The control mechanism is designed in such a way that, based on the water heating pattern in the individual boilers, the heating capacity can be apportioned to the boiler which needs it most according to a certain order of priority. At the same time the is a control so that the heating capacity accepted by the coffee machine does not exceed the available power supply. Through this variable distribution of heating capacity to the individual boilers, a large number of drinks can be supplied when the maximum available power does not suffice to supply all the heating elements with energy at the same time. The distribution of heating capacity takes place in the appliance according to the invention depending upon the energy supply and depending upon the required power of the individual boiler.
