Flat casing water-heater

Abstract

A water-heating device ( 1 ) includes a water tank and a heating unit ( 4 ). The tank has a plurality of separate and juxtaposed pipes ( 5 ) communicating via the main end thereof with a hot-water intake section and in that the secondary ends of the pipes ( 5 ) communicate with a common water-heating portion. The invention is suitable for home water-heating.

1 . Apparatus ( 1 ) for heating water comprising a water tank and heating means ( 4 ), the tank consisting of multiple separated and adjoining conduits ( 5 ) whose primary extremity ends in a common part for collecting hot water and secondary extremity ends in a common part for heating the water characterised in that
 conduits ( 5 ) have a rectangular section and the common part for heating the water is capable of receiving heating means ( 4 ) arranged perpendicular to the conduits ( 5 ).   
   
   
       2 . Apparatus ( 1 ) according to  claim 1  in which the conduits ( 5 ) are made from rectangular section tubing joined side by side. 
   
   
       3 . Apparatus ( 1 ) according to  claim 1  in which conduits ( 5 ) are formed of a series of rectangular section tubes separated one from the other by inter-tube spaces. 
   
   
       4 . Apparatus ( 1 ) according to  claim 1  in which conduits ( 5 ) are formed from partitions ( 10 ) spaced apart and extending transversally between two walls ( 11 ). 
   
   
       5 . Apparatus ( 1 ) according to  claim 4  in which partitions ( 10 ) are equipped at their periphery with at least two opposite sides of projecting tenons that are able to cooperate with receiving slots placed on the walls ( 11 ). 
   
   
       6 . Apparatus ( 1 ) according to  claim 1  in which common parts ( 2 ) ( 3 ) for collecting hot water and heating water are roughly symmetrical and have identical dimensions. 
   
   
       7 . Apparatus ( 1 ) according to  claim 1  in which at least one of common parts ( 2 ) ( 3 ) has an outer wall that overlaps the outer wall around conduits ( 5 ). 
   
   
       8 . Apparatus ( 1 ) according to  claim 1  in which the two common parts ( 2 ) ( 3 ) for collecting hot water and heating the water have at least one pluggable orifice that is able to receiving the heating means. 
   
   
       9 . Apparatus ( 1 ) according to  claim 1  in which apparatus ( 1 ) is entirely enclosed by an insulating material. 
   
   
       10 . Apparatus ( 1 ) according to  claim 1  in which the apparatus is reversible.
