The power unit preferably includes a thermostat and a power cord. The thermostat controls the flow of electrical current to the heating blanket portion. If the heating blanket portion gets too hot, the thermostat will stop the flow of electrical current to the heating blanket portion. The heating blanket portion preferably includes a heating element and a flexible outer cover. The heating element is retained within the flexible cover. The fastening device extends from a middle of one edge of the heating blanket portion. The power unit is located adjacent the one edge of the heating blanket portion. ## Claims ### Claim 1 A PVC heating blanket, comprising: a power unit includes a thermostat, said thermostat receives electrical power from a source of electrical current;
