The defogging is concentrated in the area of the heating element, but may spread out as the mirror warms up over time. There are too many variable atmospheric conditions that make it impossible to quote a fixed distance of heat spread away from the element. That is why the defogger must be placed in the area of the mirror that requires defogging.
