An electrical energy at generating station then transmitted to a load centers. The electrical energy use for various applications such as heating, lighting, welding etc. The conversion of electrical energy into other suitable for is very simple and convenient. When an electric current passed through a high resistance wire heat is produced. In simple words we can say that when heat is produced by flow of current though a wire having high resistance, the production of heat in such a way that is called a Electric Heating. This is the definition of electric heating. This is the most suitable methods over other methods of heating.

In the absence of dust and ash of the fuel, charge never gets contaminated.
Absence of Flue Gases
There is a absence of flue gases in case of this type of heating that is why atmosphere is not polluted.
buy avalide Ease of Control
We can easily control the temperature of appliances either manually as made fully automatic.
Better Working Conditions
Radiation losses are low. The operation of heating furnace is noiseless.
High Efficiency of Utilization
In electric heating, source of heat can be brought directly to the point where heat is required thereby reducing losses and increasing efficiency.
In this method, material can be heated uniformly. Uniformity of heating is closely achieved by electric heating only.
Heating of Non-Conducting Materials
It is possible. Only with electric heating to get non-conducting materials heated very uniformly through out the section.
Different Methods of Electric Heating
Requirements of a Good Heating Material
- Heating material should have high resistance so that small length of wire may be required to produce given amount of heat.
- It should have high meting point.
- It should have low temperature coefficient of resistance.
- Heating material should be free from oxidation. It means if should not oxidize at the temperature of the furnace.
