A thermal management system for gas flow from an on board high pressure vehicle gas storage tank comprising an on board heat source operatively interconnected with a heater disposed in proximity to the metal component gas outlet flow control system of the on board tank; a thermostat regulating the flow of heat to the heater such that the thermostat regulates the temperature of the metal component outlet flow control system of the tank to a temperature corresponding to at least the minimum lower limit temperature permitted by the temperature tolerance range of metal component outlet flow control system of the tank; and an optional insulating shroud circumferentially disposed surrounding the gas flow heater installed in the system.
