PROBLEM TO BE SOLVED: To increase the quantity of radiation by efficiently transmitting heat of combustion gas to a radiation surface in a radiation heater. SOLUTION: This heating system is composed of a heat gathering surface 34 heated by heat of high temperature gas, a radiator heated by the high temperature gas, having the radiation surface 35 for generating radiation energy, and provided with a hole 36 penetrating through the radiation surface 35 from the heat gathering surface 34, a heating duct 19 for introducing the high temperature gas to the heat gathering surface 34, and conducting heat of a high temperature gas generating means to the radiator, a guard 20 such as a wire net for passing at least a part of radiation generated by the radiation surface, and a deflecting plate 22 for deflecting wind sent by an air blowing means to a guard surface. The radiation surface is heated from both surfaces of a radiation surface 25 and the heat gathering surface 34. A heat transfer coefficient of the radiator is improved by breaking a boundary layer by the hole 36. High temperature heat of the high temperature gas generating means is transmitted to the radiator 33 by conduction, and the radiation surface 35 becomes a high temperature, and increases a radiation quantity generated by the radiation surface.
