A high efficiency heating apparatus of a boiler is provided to regenerate waste heat by absorbing waste thermal energy from the thermal energy supplied from electric heaters and permitting the absorbed thermal energy to contact the heat medium guided along a heat medium guide pipe. A high efficiency heating apparatus of a boiler, comprises a main body(10), electric heaters(20), and a heat medium guide pipe(30). The main body has an upper side with an inlet(11) and an outlet(12), and an interior with a hollow portion for accommodating a heat medium. The main body is covered with a heat insulation material. The electric heaters are arranged at a predetermined interval in the hollow portion of the main body. The heat medium guide pipe is spaced apart from the electric heaters, and arranged to surround the peripheries of the electric heaters. The heat medium guide pipe guides the heat medium sequentially from one electric heater to the next electric heater. |
