A system to generate a vapor from a liquid includes an electric heater and an elongate wick. The electric heater defines an interior void having an inner surface and a plurality of apertures, and it is formed of an electrically resistive material contained within a heat diffusing material. The elongate wick is formed of a durable elongate structure having a plurality of liquid-conducting features on the outer surface. At least a portion of the liquid-conducting features of the elongate wick proximate the first end engage at least a portion of the one inner surface of the electric heater and are capable of conducting a the liquid from a source proximate the second end of the wick along the outer surface of the elongate wick to the electric heater.
