working principle of APG appliance

Heater core principle is that energy conversion, the most widely used is converted into heat energy. Such as electric heaters, the use of metal in an alternating magnetic field generated in the swirl itself leaving the heat absorbed light energy is converted into electrical energy; such as solar water heaters, absorb sunlight and solar heat radiation photoelectron energy (photoelectric effect) is converted into heat both both; bio-energy is an energy vector organism is in the form of storing solar energy to chemical energy, which directly or indirectly from the photosynthesis of plants. In addition, there are ceramic infrared heater,nuclear energy, wind energy conversion mode these, but generally need to be converted into electrical energy use.
