Abstract
A vaporizer that adjusts to the conductivity of the water used in the vaporizer, and that also adjusts to changes in the conductivity of the water while in operation, thereby decreasing warm-up time and maintaining a relatively constant boiling rate and rate of steam production. The vaporizer includes hardware circuitry or other logic that maintains constant power supplied to the electrodes of the vaporizer to decrease warm-up time, and adjusts the current supplied to the electrodes while the vaporizer is in operation and after the warm-up period to maintain a relatively constant boiling rate and rate of steam production.
