ABSTRACT:
A electric heating apparatus for de-icing pipes includes a flexible hose with a closed bottom end and a top end. The hose has a pair of insulated wires situated within an interior of the hose and a plug coupled to the top end of the hose. The plug has a pair of contacts connected to the wires and adapted to be inserted within a conventional electrical receptacle for providing electrical power to the wires. By this structure, the hose is adapted to be passed within a pipe connected to a source of water. Next provided is a thermostat having an input connected to the insulated wires and is adapted to allow the transfer of power to an output thereof upon the detection of a temperature below a predetermined degree. The thermostat is situated within the interior of the hose adjacent the bottom end thereof. Also included is a heating coil formed within the hose, wherein the coil is connected to the output of the thermostat for radiating heat upon the receipt of power. Finally, a lead weight is coupled to the hose at the bottom end thereof for facilitating the passing of the hose through the pipe.
