Method of water heating and distribution

Abstract

A method of storing water at two temperatures, the method comprising: providing a tank divided into first and second chambers; storing water in the first chamber at a first temperature; storing water in the second chamber at a second temperature; heating water in the second chamber when the second temperature is below a predetermined second value; pumping water from the second chamber to the first chamber when the first temperature is below a predetermined first value, the first values being less than the second value; and permitting water flow from the first chamber to the second chamber while pumping water from the second chamber to the first chamber.

1 . A method of storing water at two temperatures, the method comprising:
 providing a tank divided into first and second chambers;   storing water in the first chamber at a first temperature;   storing water in the second chamber at a second temperature;   heating water in the second chamber when the second temperature is below a predetermined second value;   pumping water from the second chamber to the first chamber when the first temperature is below a predetermined first value, the first value being less than the second value; and   permitting water flow from the first chamber to the second chamber while pumping water from the second chamber to the first chamber.   
   
   
       2 . The method of  claim 1 , wherein heating water in the second chamber includes receiving water from the second chamber in a boiler, heating the water from the second chamber in the boiler, and returning the heated water to the second chamber. 
   
   
       3 . The method of  claim 1 , further comprising providing a baffle dividing the tank into the first and second chambers, the baffle including an aperture through which water from the first chamber flows to the second chamber when water from the second chamber is pumped to the first chamber. 
   
   
       4 . The method of  claim 1 , further comprising providing a first outlet for supplying water from the first chamber to a first recipient. 
   
   
       5 . The method of  claim 4 , further comprising providing a cold water inlet for receiving cold water in the first chamber, and replenishing water drawn from the first chamber via the first outlet with cold water from the cold water inlet. 
   
   
       6 . The method of  claim 5 , further comprising providing a second outlet for supplying water from the second chamber to a second recipient, and replenishing water drawn from the second chamber via the second outlet with water from the first chamber through the aperture in the baffle and replenishing water in the first chamber with water from the cold water inlet.
