The invention concerns a method and a device for operating a heating and cooling machine that functions on the basis of a regenerative gas cyclic process, in particular a Vuilleumier heat pump, having a burner (34) as the source of the thermal driving, in which, to increase its efficiency or to maximize the output number of the heating and cooling machine, the combustion air conveyed to the burner (34) is preheated in the heat exchange with the exhaust gases. It is proposed that, for increasing the output performance of the heating and cooling machine, the preheating of the combustion air is forestalled at least partially, whereas in response to a simultaneous increase of the burner output, the hot exhaust-gas mass-flow is conveyed to an exhaust-gas-water heat-exchanger (50). In this manner, the output of the heating and cooling machine system is increased in an advantageous manner, without having to change the design data or the size of the heating and cooling machine.
