PROBLEM TO BE SOLVED: To obtain a vacuum steam heating apparatus capable of reducing waste of cooling water as much as possible. SOLUTION: A steam supply pipe 3 is connected to a jacket part 11 of a reaction kettle 1. A steam pressure regulating valve 7 and a vapor-liquid separator 4 are fitted to the steam supply pipe 3. A fluid supply pipe 6 and a surplus fluid discharge pipe 9 are connected to pipes branched from a circulation line 16 of a suction means 2. A pipeline 18 is connected to the surplus fluid discharge pipe 9 and communicated with a unit 17 for forcibly sending a liquid. A liquid outflow port of the unit 17 for forcibly sending the liquid is connected to the steam supply pipe 3 by a pipeline 35. The superheated steam to be supplied from the steam supply pipe 3 to the jacket part 11 is cooled to the predetermined temperature by the cooled fluid to be supplied from the fluid supply pipe 6 and from the surplus fluid discharge pipe 9 and the pipeline 18.
