To ensure correct and reliable use of the electric heater, it must be installed and used by qualified personnel, and the heater must be carefully maintained. Only when used by qualified personnel familiar with the installation, startup, use, and maintenance of similar heaters can the electric heater operate well. The operator must read this instruction manual carefully. The safety instruction manual is included in the accompanying materials of the electric heater, containing relevant safety specifications and effective electrical installation and operation content. This electric heater is manufactured and tested according to standards. The electric heater has intact protective devices when leaving the factory. To protect and ensure the safe use of the electric heater, the user must pay attention to the relevant descriptions in the instruction manual. If not operated according to the instruction manual, it may lead to personal injury or even death, or damage to equipment and facilities connected to the electric heater. In any case, if the content designed in the instruction manual is incorrect, please contact the manufacturer at the address in the following manual. If the electric heater is obviously damaged, faulty, or improperly stored, the electric heater cannot be operated safely.

Working Principle:
For example, an electric heater uses the eddy current generated by metal in an alternating magnetic field to heat itself and absorb energy, converting electrical energy into light energy; for example, a solar water heater absorbs solar radiation heat energy and solar light energy (photoelectric effect) and converts them into thermal energy, both; bioenergy is a form of energy that stores solar energy in chemical form using organisms as carriers, directly or indirectly derived from plant photosynthesis. In addition, there are nuclear energy and wind energy, these energy conversion modes, but generally need to be converted into electrical energy for use.

Difference between heater and frequency converter:
The frequency converter can only change the frequency of AC power, thereby changing the rotation speed of the motor to achieve the purpose of changing the output power of the motor. The heater does not rotate, so frequency conversion cannot control the heating speed.
