Electric heating

Electric heat and electric heating are provided in the heat and electrical engineering collective terms for heat or thermal energy generated by conversion from electrical energy.

In particular, since the beginning of the 20th century continued in many areas, from household appliances to industrial applications, the heating by electric heat over direct heating by firing with a fuel such as wood, coal, gas or oil through. The reasons were varied, they ranged from economic considerations as well as fire protection and security to better handling and more comfort and convenience. A disadvantage is the low efficiency, which results from the conversion between different types of energy: Since the power supply is fed in large part by thermal power plants, thermal energy in the power plant is first converted into electrical energy, and finally converted back into thermal energy in the electric heating to become. This fact has been given wider attention only in recent decades.
