PURPOSE: A hot water tank having a removable hot water boiler is provided to improve manufacturing property and productivity by independently adopting a hot water tank and a hot water boiler for a large building, an apartment or a public bath. CONSTITUTION: A hot water tank(100) adopts a connecting pipe(110), an inlet(102) and a return pipe(120). The connecting pipe has a vertical cylindrical form and penetrates the front and rear side horizontally. The inlet is communicated with a water storage tub(101) at the rear side and connected with a hot water boiler(200). The return pipe includes a circulating pump(121) and a valve(122) for circulating hot water in the water storage tub into the hot water boiler with force. In the hot water boiler, a connecting pipe(210) is inserted into the connecting pipe of the hot water tank and connected with the inlet of the hot water tank at the rear side. The connecting pipe is used to guide and supply hot water into the water storage tub. A spiral heat exchanger is connected with a boiler(221) to boil water with high-pressure high-temperature steam. The hot water tank and the hot water boiler are assembly simply at a large building, an apartment or a public bath. Therefore, productivity is enhanced and manufacturing cost is reduced.
