ABSTRACT:
A heating device for heating an item such as a carburetor uses a first PTC heating element 12 positioned compactly within a housing 10 which is directly adjacent the item to be heated. A Second PTC element 14 having a great electrical resistance increase at a prescribed temperature level is also compactly contained in the housing and is electrically connected in series to the first PTC element 12. This second PTC element 14 restricts the electric current flow through the device when the ambient temperature exceeds the prescribed temperature level.
