1. Heater, in particular heating radiator, to which the thermal energy to be conveyed is supplied by a heating fluid which passes through the heater, in the flow path of the heating fluid in the area of the heater there being provided a reaction turbine (4) in which the heating fluid passes over fluid guiding surfaces to a runner (14) carrying blades (23), and a fan (5) being arranged at the heater which fan is rotatably driven by said turbine intensifies the air flow passing said heater and thus increases the heat dissipation of the heater surfaces, characterized in that an exchangeable insert (21) is arranged ahead of the runner (14) of the turbine, said insert being provided with flow guiding surfaces (22) and directing the flow of the heating fluid. |
