Abstract:
1. A system for keeping a medium in a container warm, comprising; a container having a heatable surface through which heat may be conducted into a medium within a container; a supply of hydrogen; a thermostatic valve having a temperature responsive member disposed in proximity with said container and operable to open in response to said temperature responsive member being below a first temperature and to close in response to said temperature responsive member being above a second temperature, said second temperature being higher than said first temperature, said valve connected to said supply to provide, when said valve is open, a source of hydrogen for combustion to heat said heatable surface; and a hydrogen/oxygen catalytic combustor selected from said heatable surface in contact with one of said heating surfaces, whereby hydrogen passing through said valve is catalytically combusted to heat the medium within said container.
