Since the starting of an engine at a lower temperature is troublesome, the temperature of the engine is measured by a sensor. When the measured temperature is lower than a reference temperature, the pump is first switched on for circulating a thermal medium. This permits the thermal medium to transfer heat of the hot water stored in a hot water storage tank to the engine, hence warming the engine, decreasing the viscosity of the oil, and preventing the generation of dew in the engine to ease the start up of the engine.

1. An engine waste heat recovering apparatus which circulates a thermal medium through a heat recovery section of the engine to recover waste exhaust heat from the engine, comprising:an exhaust gas waste heat exchanger in an exhaust gas conduit for exchanging exhaust gas waste heat to a thermal medium; a conduit for circulating the thermal medium across a heat exchanger in an external hot water storage tank; a pump mounted across the conduit, a means for measuring the temperature of the engine; and a controller for switching on the pump before starting the engine when the temperature of the engine at the start up is lower than a reference temperature predetermined for permitting the engine to be started.
