Disclosed is a heating pipe installed in buildings or in agricultural greenhouses (vinyl houses) as heating equipment or used for drying agricultural and marine products. The heating pipe has a dual pipe, structure, which maintains a vacuum state after working fluid is filled in a pipe body. The heating pipe has a heat source pipe having a predetermined length and installed in the pipe body and a sealing cap coupled to both ends of the pipe body in order to seal both ends of the pipe body. The heat source pipe passes through the sealing cap. The heating pipe can be easily fabricated by improving a cap coupling structure at both ends of the pipe body, while maximizing heat transfer efficiently of working fluid by directly installing the heat source pipe in the heating pipe, thereby reducing energy loss of a beat source and improving an energy consumption rate.
