Claim:
1. An apparatus configured to generate steam comprising: at least one water inlet, an evaporation surface, a heater, disposed adjacent to the evaporation surface and configured to; heat said evaporation surface to a predetermined temperature, and a controller configured to direct a flow of water through the at least one water inlet onto multiple spaced regions of the evaporation surface, wherein a temperature of the water fed onto the evaporation surface is lower than the predetermined temperature, so that a scale formed on the evaporation surface, caused by an evaporation of the water in contact with the evaporation surface, to which water is fed cools at a different rate than a scale, formed on a remainder of the evaporation surface, cools, thereby causing the scale formed on the multiple spaced regions on the evaporation region and on said remainder of the evaporation surface to break apart and be dislodged from said evaporation surface.
