PROBLEM TO BE SOLVED: To provide a portable heat conveying device for a combustion heat to perform fluctuations in operation and stable regulation of a catalyst temperature. SOLUTION: This device is of a constitution that by using gas feed opening closing means A15 and B21 using ferrite to increase and decrease a magnetism absorption force at a given temperature, two gas feed opening closing means A15 and B21 are switched by a gas passage switching means 22. Reproducibility is provided, stable regulation of a heating medium temperature is made practicable, and regulation temperature is also made variable.
