1. Unveiling the World of Ceramic Heaters
Ceramic heaters, also known as grommet heaters, are innovative devices utilizing ceramic material for efficient heat transmission. These heaters employ a flat ceramic disc to generate heat. As the fan operates, the heated disc, connected to a metal element, conducts warmth through convection, releasing the soothing warmth into the surrounding environment.

2. Structure and Working Principles of Ceramic Heaters
The ceramic element within a ceramic heater takes the form of a flat ceramic disc, known as the grommet disc. This disc is connected to a metal component. As the ceramic disc heats up, it transfers heat to the metal wire, and the resulting thermal convection gradually radiates warmth outward, effectively raising the room temperature without causing thermal shocks.

This machine operates without causing fatigue to individuals with lower joints, making it suitable for users of all ages, from children to the elderly.
The heating element is often made of non-corrosive aluminum, ensuring the ceramic heater's durability over prolonged use.
This is a stylish and modern heater, featuring a youthful design. It utilizes an air suction mechanism from the back, heating up through the ceramic element inside, and then expelling warm air outward to effectively warm up the room.
3. Pros and Cons of Ceramic Heaters
Advantages
- Compared to halogen heaters, ceramic heaters provide superior heating efficiency. Thanks to the convection heat mode, the fan circulates hot air evenly throughout the room, ensuring better and more even heating coverage.
- Ceramic heaters boast a compact size and modern design, making them easy to move around. They are not bulky or heavy like oil heaters, offering an elegant appearance suitable for various spaces.

- When heating, ceramic heaters do not burn oxygen or emit light like halogen heaters. This provides a comfortable and safe sensation, especially for the elderly and young children, without concerns about dry skin or respiratory issues.
- Ceramic heaters can effectively warm up room spaces ranging from 25 to 40 square meters, suitable for bedrooms, living rooms, personal workspaces, and more.
- Some models come with a humidifying feature to balance air moisture, creating a cozy and safe atmosphere in the room.
- Ceramic heaters include overheat protection and automatic shut-off when knocked over. They also feature remote control and a timer function for safe and convenient usage.
- Ceramic heaters warm up quickly, faster than oil heaters. They provide gentle warmth without the intense heat of oil heaters, distributing even heat throughout the room.
Drawback
- If the air temperature is below 10 degrees Celsius, the heating efficiency of ceramic heaters is not as high, and they are less effective compared to oil heaters.
- The price of ceramic heaters is relatively high, ranging from 1.5 million to 3 million VND.
- Ceramic heaters have received feedback for generating noise, similar to the sound of running a loud air conditioner. They are not as quiet as oil heaters.
4. Why are Ceramic Heaters Pricier Than Other Types of Heaters?
- Ceramic heaters do not deplete oxygen, maintain humidity balance, reduce eye strain, feature a safe power-off mode, emit gentle and even heat throughout the room. Ideal for use with children, the elderly, and individuals with health conditions.
- High aesthetic appeal, compact and user-friendly. Ceramic heaters with a tall design take up minimal space, available in neutral colors like black, white, and gray, suitable for any space.
- The control panel can be touch-sensitive or have LED-backlit buttons for a modern display, providing easy control over the fan's operating modes.
