Abstract
A temperature measuring device and a flowrate measuring device are both connected to a regulating unit, thus enabling the mixing temperature of the mixing water flowing through a supply line and the flowrate to be determined. The regulating unit serves for controlling a mixing valve and a shut-off valve. At the end of the filling operation, the overall volume introduced into a container and input via a control apparatus has the likewise input desired temperature, the regulating unit continuously determines, based on the flowrate and the measured mixing temperature, since a starting time point, the actual heat quantity contained in a part volume which has already flowed out. By virtue of this determination, and based on the target heat quantity to be stored in the respectively predetermined overall volume in the case of the predetermined desired temperature, if appropriate, the regulating unit causes the mixing temperature to be increased or reduced by changing the mixing ratio between the hot water supplied to the mixing valve via a first supply line and the cold water supplied via a second supply line.
