Yes indeed, the heat (energy) generated in the wire by the collision of electrons with nuclei ("resistance" to the flow of said electrons) is then (conserved) but transferred to the changing of liquid into steam; thus, vaping. The electrons which are moving along the wire take some time/distance of travel before a sufficient number of them collide with nuclei to generate sufficient heat to, say, glow, or generate steam for that matter. If you look at any glowing coil (see previous picture, or do an image search), you will note that the ends don't glow, and furthermore, that the center glows brightest. The only way to change this pattern is to interfere with the flow of electrons in some other way; say, for example, wrapping it too tightly around a tube of stainless steel mesh.
