The heating tank is equipped inside a case. A heat transfer medium in a liquid or gas state is stored inside the heating tank. The electric heater is equipped inside the heating tank and heats the heat transfer medium. The radiator is connected to the heating tank and generates heat by circulating the heat transfer medium heated in the heating tank. The circulation pump is equipped on a circulating pipe(43) connecting the heating tank and the radiator. The ventilation fan is equipped on one side of the radiator and compulsorily circulates air to pass through the radiator. |
