A hot water heating device using waste gas heat of a boiler pipe is provided to reduce fuel cost by using hot water stored in a conventional heating without operating a boiler for additional fast hot water. A hot water heating device using waste gas heat of a boiler pipe includes a hot water tub(10), an inner flue(50b), a water introduction pipe(40), a connection pipe(20), and a vortex generation film(51). Exhaust gas flows through the inner flue. A combustion portion of a boiler generates the exhaust gas and discharges it to an inside of the hot water tub. The water introduction pipe is installed at a lower side of the hot water tub, and supplies water to an inside between the inner flue and a body. The connection pipe supplies a hot water of the hot water tub. The inner flue functions as a path in which the exhaust gas moves. The vortex generation film is formed inside the inner flue and generates vortex to suppress a flow of the exhaust gas. |
