Overview of Spiral Electric Heat Tracing
Electric heating is the process of converting electrical energy into thermal energy. Since the discovery that electric current passing through a conductor can produce a thermal effect, many inventors around the world have been engaged in the research and development of various electric heating appliances. The development and widespread application of electric heating, like other industries, follows a pattern: gradually spreading from advanced

countries to the rest of the world; from cities to rural areas; from collective use to household and then personal use; products evolving from low-end to high-end. In the 19th century, electric heating appliances in their infancy were mostly crude. The earliest electric heating appliances were for domestic use. The prototype of the electric iron first appeared and was used in the United States in 1893, followed by the electric stove in 1909, which involved placing an electric heater in the stove, meaning heating shifted from firewood to electricity, i.e., from electrical energy to thermal energy. However, the rapid development of the electric heating appliance industry truly began
