Abstract
A heating unit for use in heating a fluid conduit is disclosed. The heating unit includes first and second pliable cover layers. A pliable electrical heating element is disposed between the first and second cover layers. The pliable electrical heating element includes a heat generating element for converting electrical energy to heat energy and a heat spreading element that is attached to the heat generating element. The heat spreading element comprises carbon that is thermally coupled to the heat generating element for distributing the heat energy. A thermal insulation layer is attached to a second side of the pliable electrical heating element and is positioned adjacent the first cover layer. Additionally, a receiving power connector is electrically connected to the heat generating element and is configured to couple to an electrical power source. The heating unit is sized to substantially cover the fluid conduit.
