A heater is a device that can generate or produce high temperature. Generally, the maximum temperature is about 70-300°C. It consists of three parts: heating, heat dissipation, and temperature control. From small household water heaters to large industrial boilers, they are all derivatives of heaters. The heater is just a general term for these products. There are thousands of different types of products, which are used in various fields and play an important role.
A heater is an energy conversion device. The energy input into the heater includes chemical energy from fuel, electrical energy, thermal energy from high-temperature flue gas, etc. After conversion by the heater, it outputs thermal energy at a certain temperature, thereby heating air or other media to achieve the desired purpose. The high temperature generated by the heater can directly provide the required thermal energy or heating for industrial production and public life. Large heaters are mainly used in industry, while small fan heaters are mainly used in daily life.
In fact, a heater is just one type of heating device. As early as World War II, heaters first appeared abroad. At that time, they were not particularly popular due to high prices and lack of energy. Manufacturers mainly supplied them to large enterprises and the military.But in the 21st century, this product experienced a blowout, rapidly occupying the market in various industries and fields such as factory production, engineering construction, and agricultural heating, replacing many bulky and restrictive products like boilers and heaters.

The core of the heater principle is energy conversion, with the most common being the conversion of electrical energy into thermal energy. For example, electric heaters use metal to generate eddy currents in an alternating magnetic field, causing self-heating and absorption, converting electrical energy into light energy; for example, solar water heaters absorb solar radiation thermal energy and solar light energy (photoelectric effect) and convert them into thermal energy, sometimes both; bioenergy is a form of energy stored as chemical energy using organisms as carriers, directly or indirectly derived from plant photosynthesis. In addition, there are other energy conversion modes such as nuclear energy and wind energy, but they generally need to be converted into electrical energy for use.
