PURPOSE:To facilitate to control the temperature or the like of fluid to be heated by a method wherein heat is deprived from heating fluid by the evaporating section of a heat exchanger arranged in a heating fluid line while the heat is given to the fluid to be heated by the condensing section of the heat exchanger arranged in the line of fluid to be heated. CONSTITUTION:The evaporating section 11 of the separate type heat pipe heat exchanger is arranged in the line of one kind of heating fluid discharged from the boiler 1 and the condensing sections 16-18 of said heat exchanger are arranged in respective lines for the plural kind of fluids to be heated which are supplied to the boiler while said evaporating section 11 and the condensing section 16-18 are connected respectively so as to circulate the fluid by pipelines 12-15, 19-21, 23. According to this method, heat is deprived from the heating fluid by the evaporating section 11 and the heat is given to a plural kind of fluids to be heated to retrieve the waste heat, the control of temperatures, flow amounts or the like of respective fluids to be heated may be facilitated and, further, the combustion of the boiler is stabilized and the safe operation may be effected, whereby the efficiency may be improved.
