The wrapped en heating assembly includes an outer insulation sleeve and a pocketed heating system that is fixed to an inner surface of the outer insulation sleeve in a manner that forms longitudinal pockets that extend between a first end of the outer insulation sleeve and a second end of the outer insulation sleeve. One or more heater strips are each respectively inserted longitudinally into a corresponding one of the pockets, wherein heat is generated by the heater strips when electrical current flows through the heater strips for heating the tubular member in a wrapped position. Multiple wrapped heating assemblies may be daisy chained together by electrical connectors into a heating system with a single thermostat and linked to a single power source to accommodate a wide range of configurations of tubular member systems. ## Claims ### Claim 1 A wrapped heating assembly that may be wrapped around a tubular member for heating the tubular member, the wrapped heating assembly comprising: an outer insulation sleeve; a pocketed heating system that is fixed to an inner surface of the outer insulation sleeve in a manner that forms one or more longitudinal pockets that extend between a first end of the outer insulation sleeve and a second end of the outer insulation sleeve opposite from the first end; and one or more heater strips, with each one of the heater strips being respectively inserted longitudinally into a corresponding one of the pockets, wherein heat is generated by the heater strips when electrical current flows through the heater strips. ### Claim 2 (depends on 1) The wrapped heating assembly of claim 1, wherein the pocketed heating system is fixed to an inner surface of the outer insulation sleeve in a manner that forms a plurality of pockets. ### Claim 3 (depends on 2) The wrapped heating assembly of claim 2, wherein a number of heater strips differs from a number of pockets. ### Claim 4 (depends on 1) The wrapped heating assembly of claim 1, wherein the outer insulation sleeve is made of a carbon fiber material. ### Claim 5 (canceled) ### Claim 6 (depends on 4) The wrapped heating assembly of any of claim 4, wherein the outer insulation sleeve includes a protective coating material applied to an outer surface of the carbon fiber material. ### Claim 7 (depends on 6) The wrapped heating assembly of claim 6, wherein the protective coating material is a urethane coating. ### Claim 8 (depends on 4) The wrapped heating assembly of any of claim 4, wherein the insulation sleeve further includes an aluminum E-glass layer on an inner surface of the carbon fiber material. ### Claim 9 (depends on 1) The wrapped heating assembly of any of claim 1, wherein the pocketed heating system is stitched to an inner surface of the outer insulation sleeve by a thread material. ### Claim 10 (canceled) ### Claim 11 (depends on 1) The wrapped heating assembly of any of claim 1, wherein the pocketed heating system comprises a multi-layered material including a mesh inner layer and a heat reflective outer layer. ### Claim 12 (canceled) ### Claim 13 (depends on 1) The wrapped heating assembly of any of claim 1, wherein the insulation sleeve has an edge portion including a fastener element, wherein the fastener element joins opposing edge portions of the insulation sleeve together to secure the wrapped heating assembly in a wrapped position. ### Claim 14 (depends on 13) The wrapped heating assembly of claim 13, wherein the fastener element is a double mechanical strip fastener that extends longitudinally along at least one of the opposing edge portions of the insulation sleeve. ### Claim 15 (depends on 1) The wrapped heating assembly of claim 1, further comprising an electrical connector to provide an electrical connection to the one or more heater strips. ### Claim 16 (depends on 1) The wrapped heating assembly of claim 1, further comprising a thermostat including control circuitry that controls a flow of electrical current through the one or more heater strips. ### Claim 17 (depends on 16) The wrapped heating assembly of claim 16, wherein the thermostat is a bimetallic disc thermostat. ### Claim 18 (depends on 1) The wrapped heating assembly of claim 1, wherein the wrapped heating assembly is flexible when in a wrapped position. ### Claim 19 (depends on 1) The wrapped heating assembly of claim 1 comprising a plurality of heater strips respectively inserted into a plurality of pockets. ### Claim 20 (depends on 19) The wrapped heating assembly of claim 19, wherein at least two of the heater strips have a different heat output capacity. ### Claim 21 (canceled) ### Claim 22 (canceled) ### Claim 23 (depends on 1) A daisy chained heating system of a plurality of wrapped heating assemblies comprising: a plurality of wrapped heating assemblies according to claim 1, wherein adjacent wrapped heating assemblies each has a complementary electrical connector that are connected to each other to permit current flow between heater strips of adjacent wrapped heating assemblies. ### Claim 24 (depends on 23) The daisy chained heating system according to claim 23, further comprising a thermostat including control circuitry that controls a flow of electrical current through the one or more heater strips of all of the plurality of wrapped heating assemblies. ### Claim 25 (depends on 23) The daisy chained heating system according to claim 23, further comprising a connector for connecting one of the plurality of wrapped heating assemblies to a power source, wherein the power source supplies current to each of the plurality of wrapped heating assemblies via the electrical connectors.
