This reduces the amount of water sent into the vaporization chamber when the electrical resistance does not provide energy to vaporize the water, which reduces the risk of ejection of water droplets with the steam flow. . Conversely, when the electric resistance is supplied electrically, the available power is taken advantage of to increase the pump flow rate and produce a larger quantity of steam without the risk of water accumulating in the instantaneous vaporization chamber.
