Abstract: A liquid tank device comprises a tank housing for storing a liquid within a tank volume inside of the tank housing, whereby the tank housing comprises at least one conduit opening that can be connected in a liquid-tight manner to at least one conduit for the liquid such that the liquid can be supplied to or removed from the tank volume within the tank housing through the conduit opening. A method for warning of and avoiding critical operating conditions of a liquid tank device comprises the detection of a tilting of the tank housing by means of a tilt detection device. The tank volume is shut off from the at least one conduit by means of a closing device if a tilt information from the tilt detection device exceeds a preset tilt value, resulting in avoiding further flow of liquid into or from the tank volume through the at least one conduit after detecting the tilting of the tank housing.

Abstract: A hot water heating device includes a heating chamber with a water inlet for feeding water into the heating chamber and with a water outlet for removing hot water from the heating chamber. The water outlet includes an outlet duct with a suction opening arranged within the heating chamber at a distance to a bottom of the heating chamber and facing a top side opposite of the bottom of the heating chamber. The hot water heating device further includes a heating element arranged within the heating chamber for heating the water within the heating chamber. The water outlet further includes a steam bubble retention device that forms a water intake duct that runs into the suction opening of the water outlet and that prevents steam bubbles to flow through the suction opening of the outlet duct. The steam bubble retention device includes an intake duct with an intake opening and with a muzzle opening that runs into the suction opening of the outlet duct, whereby a cross-sectional area of the intake opening of the intake duct is larger than the cross-sectional area of the suction opening of the outlet duct.

Abstract: A method for controlling a temperature of a liquid in a liquid container filled with at least a first predetermined amount of the liquid using a heating device. The temperature of the liquid in the liquid container is measured and controlled by adjusting the heat output of the heating device. If the liquid container is filled with less than the first predetermined amount of liquid until the liquid container is filled with a second predetermined amount of the liquid, wherein the second predetermined amount of the liquid is equal to or greater than the first predetermined amount of the liquid, cool liquid is fed into the liquid container from a liquid reservoir, the heating device is permanently activated, and the temperature of the liquid in the partially filled liquid container is controlled.

Abstract: A method of operating a water tap, in particular a hot water tap, including a dispensing step in which water is dispensed from the water tap. Initiation of the dispensing step requires several preceding steps, including an actuation of a first actuating element and an actuation of a second actuating element. Within an actuation step, the actuation of a first actuating element is detected by a control unit. The actuation step also includes an unlocking step, in which, upon detection of the actuation of the first actuating element, an unlocking time window is started by the control unit. The actuation step also includes an activating step in which the actuation of the second actuating element activates a dispensing switch. The dispensing step is only initiated in case that the activating step is triggered within the unlocking time window.
