Abstract

A liquid fuel air heater (10) comprises a housing (14) defining a motor housing portion (22) and a grip portion (30) extending from the motor housing portion (22). An electric motor (24) is positioned in the motor housing portion (22). A combustion chamber (18) is at least partially positioned within the motor housing portion (22). A fan (26) is driven by the motor (24) when activated for generating an axial airflow through the combustion chamber (18). A battery pack (32) containing a plurality of battery cells connected to each other in a series or parallel arrangement is removably coupled to the grip portion (30) of the housing (14) for supplying power to the motor (24).
