Provided is a warm air circulator using waste heat of exhaust gas comprising: a natural exhaust pipe for naturally exhausting some of exhaust gas introduced from a water heater; a forced exhaust pipe which is connected in parallel with the natural exhaust pipe and through which the remaining exhaust gas except the naturally exhausted gas is introduced; a heat exchanger which is disposed above the forced exhaust pipe and to which exhaust gas of high temperature is supplied; an air blower for forcibly exhausting the exhaust gas to inhale and discharge the exhaust gas from the forced exhaust pipe; a main body part in which the heat exchanger is mounted and which has an outside air circulating part for circulating the inside air of low temperature into the heat exchanger; an air blower for circulating warm air which supplies the inside air of low temperature toward the outside air circulating part and circulates the inside air of low temperature so as to carry out heat exchange of the exhaust gas; and a control part for operating and stopping the air blower for forcibly exhausting and the air blower for circulating warm air. The warm air circulator according to the present invention exchanges heat with the forced exhaust pipe connected in parallel with the natural exhaust pipe of the water heater in order to resupply air by exchanging heat between the exhaust gas introduced through the forced exhaust pipe and the inside air, thereby reducing heating costs by minimizing power consumption for supplying warm air to the inside. |
