Woory Electric Heat is a leading manufacturer of cartridge heaters in Korea.
To understand the principle of a radiator, you need knowledge of heat transfer. There are three types of heat transfer, heat conduction, convection, and radiation. Each method does not transfer separately, but works comprehensively to achieve heat transfer.
Depending on the fuel used to operate the heater, there are largely an electric type that uses electricity and a fuel type that uses gas or oil. Since it is the most commonly used fuel, it is easy to purchase heaters that can run on that fuel.
|Quartz tube||affordable price, Excellent heat efficiency||High power consumption, Slow fever rate|
|Carbon||Immediate fever possible, Pay less electricity bill||The heating element material is expensive|
|Near infrared||Medical near-infrared application||high price|
|ceramic||affordable price, The temperature rises rapidly||Slow fever rate, High electricity usage|
|halogen||affordable price, Long life||Risk of lamp breakage, Weak to shock|
The quartz tube is a heater that generates heat because a heater is built into the glass tube. The heat efficiency is excellent, but the heating rate is slow, so you need to wait. However, it is also available in a mini size at an affordable price, so it is suitable for easy use.
Carbon heater is a product made with carbon fiber. It emits light rays harmless to the human body and does not heat the air, making it suitable for indoor use. However, there is a disadvantage that the heating element material itself is expensive compared to other heaters.
The near-infrared heater uses a special coating to emit near-infrared rays on the lamp and uses it as a heating element. It is also a heater that acts directly on the human body rather than heating air.
Ceramic heaters are the easiest heaters to find around. It is said to have high efficiency as heat reaches a large area by winding a heating element, which is a heating element, to generate heat. It reacts with the moisture in the skin and the temperature rises quickly, so you can feel even warmer. However, it heats up slowly and it takes a while to warm up.
Halogen heater is a heater that creates a heating effect by converting light from a halogen tube made by injecting halogen gas into heat. Compared to other heaters, it is a type that is sold a lot recently because it is cheaper and has a longer life. However, since the lamp is used, it is vulnerable to impact and the risk of damage is high.
|rank||Degree of waterproof protection||rank||Degree of waterproof protection|
|X||No protection||5||Protection against low pressure water jets from all directions|
|1||Protected against vertically falling water rain||6||Protected against high pressure water jets from all directions|
|2||Protected against water droplets falling in the vertical 15˚ range||7||Immersion from 15CM to 1M|
|3||Protected against water droplets falling in the vertical 60˚ range||8||1M or more immersion|
|4||Protected against water droplets falling from all directions|
There is also a heated bathroom heater, not a heated type. Although the burden of electricity bills is relatively small, a warmer is a little more suitable for bathrooms that require short-time heating because preheating is required. Although this product is used in the bathroom, of course, it can also be used outside the bathroom. Conversely, some electric heaters and air heaters also contain waterproof features, but for safety, it is recommended to use a product exclusively for the bathroom.
Radiator and convector are products using convection. They both use natural convection, but the difference is that they work fundamentally.
