Abstract
In a water heater, an outer casing includes a hollow flue tube that extends vertically from an inner periphery of a bottom wall thereof, and an outer surrounding wall that extends uprightly from an outer periphery of the bottom wall and that cooperates with the flue tube to confine a receiving space. A heat-conducting unit is mounted inside the receiving space so as to configure the receiving space with isolated first and second chambers. The first chamber is filled with a thermal superconductor material. The second chamber is adapted for holding water therein. The heat-conducting unit includes a plurality of interconnected upright tubular members that cooperate with the outer casing to confine the first chamber therein. The second chamber is disposed externally of the tubular members. A heat-generating source is mounted below the outer casing for heating the water inside the second chamber.
