Water heater

A water heater, comprising:

• a heat-conducting assembly including:
• an outer casing including a bottom wall that is formed with a bottom hole and that has an outer periphery and an inner periphery confining said bottom hole, a hollow flue tube that extends vertically from said inner periphery, and an outer surrounding wall that extends uprightly from said outer periphery and that cooperates with said flue tube to confine a receiving space with a top opening, and
• a heat-conducting unit mounted inside said receiving space of said outer casing so as to configure said receiving space with isolated first and second chambers, said first chamber being filled with a thermal superconductor material, said second chamber being adapted for holding water therein, said heat-conducting unit including a plurality of interconnected upright tubular members that cooperate with said outer casing to confine said first chamber therein, said second chamber being disposed externally of said tubular members, each of said tubular members having a closed upper end;
• and
• a heat-generating source mounted below said heat-conducting assembly for heating the water inside said second chamber.
