— the heating coil is a high-resistance metal wire covered with a thin layer of insulating material. The advantages of such a heater are high efficiency and a minimum of thermal inertia — in other words, it heats up and cools down almost instantly. This facilitates precise temperature control. In addition, the heating coil is not subject to scale. At the same time, the service life and overall reliability of such heaters are much lower than those of heating elements.
