The invention discloses an energy-saving fired stove, which is provided with a smoke tube and an outer water tank, wherein a middle layer water tank and an inner layer water tank are arranged above an internal hearth of the stove; the outer water tank consists of an inner layer and an outer layer between which a heat conducting layer is arranged; superconductive liquid is arranged in the heat conducting layer; the bottom of the middle layer water tank is provided with an ash cleaning port; an ash cleaning door is arranged on the ash cleaning port; the outer water tank is communicated with an upper water tank above the outer water tank; and the inner layer water tank is communicated with the upper water tank. After the scheme is adopted, heat of smoke of a combustion chamber is fully absorbed due to the arrangement of the heat conducting layer; as measured, the utilization rate of the heat of the fired stove is obviously improved; and in addition, the structure is low in manufacturing cost.
