PROBLEM TO BE SOLVED: To provide a governor heater system capable of controlling quantity of supplied heat following fluctuation of gas communication quantity in a governor, and providing economical operation of a governor heater even when heat exchange efficiency is high. SOLUTION: In the governor heater 3 heating gas cooled by decompression of the governor 4, the governor heater 3 composed by arranging a heat exchange part 3D communicating gas is provided in a sealed vessel 3 circulating hot water, a plurality of water heaters 10 controlling the quantity of supplied heat to the hot water by changing the number of operating water heaters in response to the communication quantity of gas is arranged in a circulation passage of the hot water, and the quantity of supplied heat to the hot water is made to follow the fluctuation of the gas communication quantity. A gas flow rate detecting means 30 is provided in a gas piping 1C in a governor 4 downstream side, a recirculation amount adjusting means 13 is provided in the circulation passage of the hot water for adjusting a flow rate of hot water returning to the water heaters 10, the recirculation amount adjusting means 13 is adjusted by an output of the gas flow rate detecting means 30, and the number of operated water heaters 10 is controlled in response to the flow rate of the hot water returning to the water heaters 10.
