The above site gives overall description of basic thermos principle. Electric thermos is merely one that has an electric heating coil inside.

The thermos or vacuum flask is simple in operation: The inner container has a silver reflective coating on its outer surface and is inside a vaccum chamber that prevents conduction and radiation heat from getting into or out of the inside container.

Hope this covers the subject, but if still you have questions, let me know.
