How does the 650-2000W 3 Power Heating Levels Outdoor Electric Patio Heater generate heat? Does it use infrared radiation?

Principle of heat generation
The 650-2000W 3 Power Heating Levels Outdoor Electric Patio Heater is equipped with electric heating elements inside. These electric heating elements are usually made of materials such as resistance wire or electric heating film. When the power is turned on, the current passes through the electric heating element, causing the resistance inside the element to generate heat. This is based on the principle of Joule's law (the heat generated by the current passing through the conductor is proportional to the square of the current, the resistance of the conductor, and the power-on time).

Infrared radiation
As the temperature of the electric heating element increases, it begins to radiate heat outward in the form of infrared rays. Infrared rays are a type of electromagnetic wave with a wavelength between visible light and microwaves. Unlike traditional convection or conduction heating methods, infrared heating directly radiates heat to the object, that is, after the infrared rays are absorbed by the object, they are directly converted into heat energy, causing the temperature of the object to rise.

Advantages of infrared heating
High efficiency: Infrared heating has very high thermal efficiency, because infrared radiation can directly act on the surface of objects, reducing the loss of heat in the air, thereby improving heating efficiency.
Uniformity: Infrared heating can ensure uniform heating, because infrared radiation can penetrate the surface of objects and heat the inside of objects, avoiding the problem of overheating of the surface and insufficient internal temperature of objects that may be caused by traditional heating methods.
Environmental protection: Since infrared heating does not require the burning of fuel, it does not produce harmful gases or greenhouse gases, which is environmentally friendly.
Safety: The design of infrared heaters usually includes safety features such as overheating protection and dumping power off to ensure the safety of use.
Comfort: Infrared heating can give people a warm and comfortable feeling, because infrared radiation is similar to the wavelength of far infrared rays naturally emitted by the human body and is easily absorbed by the human body.
Practical application
This outdoor electric terrace heater can provide a warm environment for outdoor spaces such as terraces and gardens in a short time through infrared radiation. It is very suitable for outdoor gatherings, barbecues, open-air dining and other occasions. At the same time, its waterproof and wear-resistant design also enables it to work stably in a variety of weather conditions, providing users with a long-lasting heating experience.
