Zusammenfassung:	PROBLEM TO BE SOLVED: To improve fuel consumption by suppressing electric power consumed to supply cooling water in a heat storage tank to an engine. SOLUTION: An engine ECU executes a program including a step (S100) of detecting an engine cooling water temperature THW(1) and a heat storage tank water temperature THW(2); a step (S104) of forbidding the drive of an electric water pump when a value obtained by subtracting the engine cooling water temperature THW(1) from the heat storage tank water temperature THW(2) is smaller than a threshold value ΔTHW before the start of the engine(Yes in S102); a step (S106) of allowing a port A on the engine side and a port C on the heat storage tank side to communicate with each other by a three-way valve provided between the heat storage tank and the engine; and a step (S112) of cranking to start the engine for driving a mechanical water pump.
