PROBLEM TO BE SOLVED: To provide an industrial heating system with high energy efficiency. SOLUTION: The industrial heating system is equipped with a heat pump device (12) passing a first fluid, a heat exchange device (14) transferring heat from the first fluid to a second fluid, and a heating chamber (16) transferring heat from the second fluid to an object. The heat pump device (12) is equipped with a multi-stage compression part (22) including a first compression part (22A) and a second compression part (22B) and compressing the first fluid, a heat radiation part (23) with at least one part disposed in the heat exchange device (14) and passing the first fluid from the multi-stage compression part (22), an expansion part (24) expanding the first fluid from the heat radiation part (23), an endoergic part (21) including a first endoergic part (21A) and a second endoergic part (21B) and wherein the first fluid from the expansion part (24) absorbs heat from the outside, and a regenerator (28) including a first regenerator (28A) and a second regenerator (28B) and transferring one part of heat of the first fluid compressed by the multi-stage compression part (22) to the first fluid heading toward the multi-stage compression part (22).
