A combined heat and electricity generating unit is suitable for use in class 8 trucks and the like. When it is operating it provides heat for keeping the engine and cabin warm and electricity for use by the electricity consuming devices in the cabin. It is a closed cycle system that includes a radial inlet turbine driven by a low pressure vaporized and superheated working fluid, an oil fired heater for vaporizing the working fluid, a pump for pumping condensed working fluid, a heat exchanger for heating engine coolant with heat from the condensing working fluid and an electric generator for converting energy produced by the turbine to electricity.
