Description of the Related Art Conventionally, in equipment using high temperature water, high temperature water is directly generated by a high temperature water boiler as a high temperature water generator, or steam for heating from the boiler is returned from a demand side by a cascade heater. The method of directly contacting the hot water and reheating it to the hot water is adopted. In this case, in order to obtain high-temperature water at the required temperature in a stable state, it is necessary to pressurize above the saturated vapor pressure of the hot water temperature anywhere in the system, and this pressurizing pressure, pump head, hydrostatic head, etc. Since pressure is applied, it was necessary to consider in advance the design and consider the piping material and wall thickness of the entire system. Further, since it is a large-scale device for generating high-temperature water, the heat capacity of the system becomes large, and it is difficult to rapidly raise the temperature of the high-temperature water. Even when the high-temperature water on the demand side is indirectly heated by the heat generated by the steam from the boiler via the heat exchanger, the steam temperature on the primary side becomes high due to the saturated steam pressure, which limits the facility. However, there was a limit to the temperature of the hot water supplied to the demand side.
