A refrigeration appliance with a hot water dispenser includes a refrigerated cabinet having a dispenser area, a cabinet water inlet in the refrigerated cabinet connectable to a premises water line, and a hot water storage tank. The tank has a tank body, a heater in the tank body, an inlet for admitting water into the tank body supplied via the cabinet water inlet, and an outlet for providing water via a dispensing conduit to a dispenser in the dispenser area. The inlet includes a venturi portion for creating a reduced pressure within the hot water storage tank via flow of water into the hot water storage tank. The reduced pressure communicates with the dispensing conduit via the outlet so that, after dispensing water remaining in the dispensing conduit is drawn toward the tank body. Refrigeration devices with premises line pressure water distribution systems are also disclosed.

1. A refrigeration appliance with a hot water dispenser comprising: a refrigerated cabinet having a dispenser area;a cabinet water inlet in the refrigerated cabinet connectable to a premises water line; anda hot water storage tank having a tank body defining an interior volume, a heater in the interior volume of the tank body, an inlet for admitting water into the interior volume of the tank body supplied via the cabinet water inlet, and an outlet for providing water via a dispensing conduit to a dispenser in the dispenser area, the inlet including a venturi portion for creating a reduced pressure within the hot water storage tank via flow of water into the hot water storage tank, the reduced pressure being in communication with the dispensing conduit via the outlet so that, after dispensing operation is completed, water remaining in the dispensing conduit is drawn toward the interior volume of the tank body, the hot water storage tank also having an evacuation chamber in communication with the inlet via a conduit extending from the venturi portion, the evacuation chamber positioned above the interior volume of the tank body and having a vent opening such that the evacuation chamber is vented to atmosphere, air within the evacuation chamber being in contact with water in the evacuation chamber,wherein water flows into the evacuation chamber via the conduit and air flows out of the evacuation chamber via the vent opening when the reduced pressure draws water from the dispensing conduit toward the interior volume of the tank body,wherein water flows out of the evacuation chamber via the conduit and air flows into the evacuation chamber via the vent opening when water from the cabinet water inlet flows through the venturi portion. 2. The refrigeration appliance of claim 1, wherein the water storage tank outlet is located in the refrigerated cabinet below the dispenser. 3. The refrigeration appliance of claim 1, wherein the evacuation chamber has a float valve therein for selectively closing a liquid opening in an end of the conduit, a that body in the float valve floating upward to open the liquid opening and to allow water to enter the evacuation chamber via the liquid opening when pressure in the interior volume of the tank body is higher than in the evacuation chamber. 4. The refrigeration appliance of claim 3, wherein the float body seals the liquid opening when water has been removed from the evacuation chamber by flow of water through the venturi portion. 5. The refrigeration appliance of claim 3, wherein the evacuation chamber is configured large enough to receive an amount of water remaining in the dispensing conduit after dispensing. 6. The refrigeration appliance of claim 3, wherein the float body seals the vent opening if sufficient water flows into the evacuation chamber. 7. The refrigeration appliance of claim 1, further including a heat transfer element for removing heat from the hot water storage tank. 8. The refrigeration appliance of claim 7, wherein the heat transfer element includes at least one of a metallic tape and a foil adhesive. 9. The refrigeration appliance of claim 1, wherein the tank body includes a descaling inlet port for receiving a descaling agent. 10. The refrigeration appliance of claim 9, further including a fill port accessible to a user, descaling agent placed in the fill port being transmitted to the tank body via the descaling inlet port. 11. The refrigeration appliance of claim 1, wherein the hot water storage tank is configured to dispense steam for cleaning the dispenser area. 12. The refrigeration appliance of claim 11, further including a cover for covering the dispenser area before steam is dispensed. 13. The refrigeration appliance of claim 12, further including a sensor located for detecting whether the cover is covering the dispenser area, and further including a controller in communication with the sensor, the controller allowing steam to be dispensed only if the sensor detects that the cover is covering the dispensing area. 14. The refrigeration appliance of claim 11, further including a supplemental heater for creating the steam. 15. The refrigeration appliance of claim 1, further including a valve between the cabinet water inlet and the hot water tank inlet, the valve being selectively openable to provide water from the premises line to the interior volume of tank body at the premises line pressure without further pumping. 16. The refrigeration appliance of claim 1, wherein the tank body is made of a plastic, and further including a metallic liner within the tank body to shield the tank body from the heater. 17. The refrigeration appliance of claim 1, wherein the tank body is located on a door covering a refrigerated compartment of the refrigerated cabinet.
