Abstract

Water heater which container is provided with an essentially horizontal partition wall with at least one opening which forms communication between an upper compartment for consumption water and a lower compartment for storage water surrounding a heating element. The pressure inlet and outlet are formed in the upper compartment.

Claims

1. Water heater comprising a heat-insulated container having direct inlet from a pressure water pipe and outlet for hot pressure water, and an electric heating element for heating water in said container, characterized in that:

said container, in the lower part thereof, is provided with an essentially horizontal partition wall which separates the container into an upper compartment and a lower compartment, said compartments being substantially co-extensive in a horizontal direction;

said wall having at least one opening which establishes communication between said upper compartment and said lower compartment;

said heating element being disposed in said lower compartment so as to be submersed in water contained therein;

said inlet and said outlet both being formed in said upper compartment, such that water in said upper compartment constitutes consumption water and water in said lower compartment constitutes storage water surrounding said heating element.

2. Water heater according to claim 1, characterized in that said at least one opening in the partition wall is provided with a downwardly directed downwardly open pipe having a volume which is sufficient to receive the volume of heat expansion of the storage water.

3. Water heater according to claim 1, characterized in that said at least one opening in the partition wall is provided with an upwardly directed, upwardly open pipe with a volume which is at least sufficient to receive the volume of heat expansion of the storage water.

4. Water heater according to claim 3, characterized in that the pipe at top is provided with a downwardly directed extension.

5. Water heater according to claim 4, characterized in that the extension is an upwardly closed cap arranged with passage over the end of the pipe and the skirt of which extending downwardly along the pipe and forming the open end of the extension.

6. Water heater according to claim 4, characterized in that the extension is formed by the open end of the pipe being bent 180°

so that the open end is extending downwardly.

7. Water heater according to claim 5, characterized in that the open downwardly directed end of the cap is provided with a conical screen the open wide end of which is directed downwardly.

8. Water heater according to claim 6, characterized in that the downwardly directed open end of the pipe is provided with a conical screen the open wide end of which is directed downwardly.
