The installation comprises an insulated container mounted on a transport device with the container receiving the vessel holding the medium with a cover which is also insulated. The insulation is fitted between the wall of the container and a metal coating (16) is fitted coaxially in the container. The metal coating carries an electric heating element (25) on its rear side and there is a box like construction (22, 23, 24) fitted to an insulation (17) on the container floor containing at least an accumulator (26) with a control circuit (27).
