Abstract
A flexible hose assembly for conveying gas comprising an inner tube member having a reinforcing spring coil that selectively functions as an electric heater engaging the inner surface and an outer flexible tube member having its head and outlet ends closed upon those of the inner member. A second reinforcing spring coil surrounds the outer surface of the outer member such that a dead air space or insulating chamber is formed between the two flexible tubes. Superior insulation, flexibility, energy consumption, weight and strength characteristics are achieved. A temperature responsive electrical device can be mounted near the outlet end of the inside wall of the inner tube with leads extending through the hose exiting the head end for connection to a controller for controlling an external heating or cooling system or for controlling electric power applied to the inner spring coil for directly heating the flowing gas for delivering temperature controlled heated gas to the end user system. The air in the chamber can be less than one atmosphere to enhance the insulating function.
