ABSTRACT:
An electric heating device for warming liquid propane gas (LPG) bottles includes a flexible heat resistant belt adapted to be secured around the outer peripheral surface of the bottle. The belt has embedded therein an electric resistance heating element with end portions of the belt being heating element-free. A dual safety system is provided on the belt for controlling the heating element and includes a low temperature (60.degree.-80.degree. F.) thermostat secured to a heating element-free end portion of the belt so as to be responsive to the temperature of the bottle and a high temperature (180.degree.-200.degree. F.) thermally-responsive device, such as a thermostat, fuse or circuit breaker located, on the portion of the belt in which the heating element is embedded, for controlling maximum temperature of the belt.
