The heating element is considered the leading component of the electric kettle. Its type affects the duration with which the liquid boils, the degree of noise accompanying the process of work.
Modern options for electric teapots are supplied either with open spirals, or more light in care and effective hidden discordant heating elements.
In the devices in which the open heater is built -in, the water has contact with the spiral, which is usually made of stainless steel. Such teapots do not make a lot of noise, and their cost is relatively affordable. In order to prevent corrosion processes and reduce deposits of lime plaque leading to scale, some manufacturers offer models with a titanium covered with nitride, which is due to this “golden” shade.
When operating electric ketters with an open heater, it is important to take into account only the nuance and follow the useful advice – always pour water until the spiral is completely hidden under it.
The area of contact of the flat heating element with a liquid is much larger. Under such a disk on outdated samples, a spiral is usually hidden, the latest developments have a disc heater with contacts connected to it. Water in such devices begins to boil faster, in addition, its number can be any. The central contact is due to the presence of a stand for the kettle, on which it can rotate in the circular. From the positive aspects, the simplicity of the removal of the scale from the heater, maximum efficiency and almost absolute noiselessness can be noted, but these electric photographs are more expensive.
However, in the end, they will cost you cheaper in operation.
