CONSTITUTION: An engine coil cooler(2) is connected with an engine(1) for circulating engine oil and engine cooling water to exchange heat. A temperature of the cooling water is increased by absorbing high heat of engine oil in circulating through the engine oil cooler. A heater core(31) of a heating apparatus(3) is connected with the engine for circulating the engine cooling water in the increased temperature to exchange heat. A cooling water pipe line(4) is installed to return the engine cooling water firstly circulated through the engine oil cooler and secondly circulated through the heater core to the engine.
