Hot water dispenser

Abstract

A hot water dispensing system includes a water tank having a heat source for heating water in the tank. The tank has a cold water inlet and a hot water outlet. An expansion chamber is connected to the water tank and situated above the water tank for receiving heated water from the water tank.

1 . A water heating system, comprising: 
 a water tank having a heat source for heating water in the tank, the tank having an inlet and an outlet; and    an expansion chamber connected to the water tank and situated above the water tank for receiving heated water from the water tank, such that water flows from the expansion chamber to the water tank when water is expelled from the water tank via the outlet.    
   
   
       2 . The water heating system of  claim 1 , wherein the water tank is made of stainless steel.  
   
   
       3 . The water heating system of  claim 1 , wherein the expansion chamber is made of stainless steel.  
   
   
       4 . The water heating system of  claim 1 , wherein the expansion chamber includes a generally funnel-shaped portion having a check ball situated therein.  
   
   
       5 . The water heating system of  claim 4 , wherein the funnel-shaped portion is connected to the inlet of the tank such that water flows from the expansion chamber, though the funnel-shaped portion to the inlet and into the tank.  
   
   
       6 . The water heating system of  claim 5 , further comprising an aspirator connected to the inlet, such that water flowing into the tank through the inlet draws water into the tank from the expansion chamber.  
   
   
       7 . The water heating system of  claim 1 , wherein the expansion chamber includes a vent tube.  
   
   
       8 . The water heating system of  claim 1 , wherein the hot water inlet is situated at the top of the tank.  
   
   
       9 . The water heating system of  claim 1 , further comprising a faucet connected to the outlet.
