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.

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: The invention relates to method for conveying a liquid into a container by means of a conveying device. The conveying device comprising a liquid reservoir, a pump and a tap. The liquid is supplied by the pump from the liquid reservoir via a tap inlet to the tap. The liquid emerges from a tap outlet of the tap and flows into the container arranged below the tap outlet. An outlet volume flow rate of the liquid flowing from the tap outlet is controlled in such a way that at first the liquid is conveyed with an initial volume flow rate until an initial delivery volume has been conveyed and then the liquid is conveyed with a final volume flow rate, the final volume flow rate being greater than the initial volume flow rate.

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: An apparatus for providing hot water, wherein the apparatus includes: a water storage container; a heating element for heating water positioned within the water storage container; and a tap, wherein the tap is positioned above the water storage container, wherein the tap is fluidically connected to the water storage container via a pipeline, wherein the pipeline comprises a pump, wherein the pipeline is at least partly formed as a riser within or through the water storage container.
