ABSTRACT:
A heater for heating elongated objects includes an elongated strip of flexible material having first and second ends and elongated opposite side edges defining a width therebetween. The strip of material comprises a fiber reinforced elastomeric material having at least a first portion that is set in a spiral. The heater also includes at least one elongated electrically conductive heating element imbedded in the elongated strip of elastomeric material. A thermostat is operably coupled to the heating element, and the thermostat is encapsulated in an elastomeric dielectric material that is bonded to the elastomeric material of the strip to provide a waterproof seal around the thermostat. The heater further includes an electrical power line extending from the thermostat for supplying power to the heater.
