Abstract
The present invention provides for a mobile heating apparatus for heating an enclosed space to a temperature sufficient to kill bed bugs. The mobile heating apparatus has a recirculation chamber having a fresh air inlet configured to receive fresh air from a fresh air area and a recirculation air inlet configured to receive recirculation air from a heated air area. The fresh air area is located outside of the area to be heated. The heated air area is located within the area to be heated. The apparatus also has an air mixture/circulation apparatus configured to mix the fresh air and the recirculation air and an air heating chamber having a heat exchanger. A mixed air inlet is in communication with the air mixture/circulation apparatus. A heated air outlet is configured to route the heated air into the heated air area. A heating apparatus is configured to provide heated combustion flow to the heat exchanger. The present invention also provides for a related method.
