Abstract
A heater for heating a rigid fluid line or hose for freeze protection. The heater has a base made of an outer base layer, a middle base layer attached to the outer base layer; and an inner base layer attached to the middle base layer. The inner base layer can be uncured silicone (before assembly processing). A resistance wire is wound around an electrically non-conductive core and located on the inner base layer. The resistance wire can be a high gauge wire providing for a small moment of flexure. A cover includes an inner cover layer covering said resistance wire. This inner cover layer can be uncured silicone (before assembly processing). A middle cover layer is attached to the inner cover layer, and an outer cover layer is attached to the inner cover layer. The outer cover layer protects the heater from abrasion.
