For heating of silicon in semiconductor industries, the inductive heating principle is used. This process is used in inductive furnaces for to heat metal to its melting point. As this is a contactless heating process, vacuum furnaces make use of this process for making specialized steel and alloys that would get oxidized when heated in the presence of oxygen.
How Do Heaters Work? Unveiling the Mechanics
Heaters work by harnessing different methods to generate and distribute heat, providing warmth during colder periods. Electric heaters employ resistance heating through heating elements, while gas heaters rely on combustion of natural gas or propane to produce heat. Wood-burning heaters, on the other hand, generate warmth by burning firewood.

Active Solar Heating | Department of Energy
Active solar heating systems use solar energy to heat a fluid -- either liquid or air -- and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat. Liquid systems are more often used ...
