The diathermic fluid heat generator comprises a plurality of pipe nests for fluid circulation, which define the internal walls of a combustion chamber, where the diathermic fluid is heated directly by radiation; and at least a pipe nest in a conveying path for the combustion gas, where the fluid is heated in countercurrent by convection. A fluid distributing header unit comprises an inlet header section, an outlet header section and a main header section having an annular form, positioned at the front side of the combustion chamber. The pipe nest of the gas conveying path is connected in series to the pipe nests of the combustion chamber, by the main header section. Moreover temperature and pressure control means are provided for controlling the fluid circulation; the control means comprise a temperature and pressure detecting device in each section of the fluid distributing header, and an electronic control unit fed by temperature and/or pressure control signals generated by each detecting device to monitor and control the generator operation.
