Graphene Far Infrared Convection Electric Heater
Natural convection physics heating with graphene mica heating plate. No oxygen consumption, no fan noise, and warm air without dryness — delivering comfortable, evenly distributed warmth throughout your space.
Natural Convection. Silent Warmth. Even Heat.
The graphene convection electric heater features an internal graphene mica heating plate. Under alternating electric fields, carbon atoms vibrate and collide to generate heat, releasing far infrared radiation. With extremely high electrical-to-thermal conversion efficiency and minimal heat loss, the device operates without ultraviolet or visible light emission and produces no high-frequency radiation.
Emitting 8–18 μm far infrared light waves, it delivers a warm, gentle heating sensation. The unit consumes no oxygen during operation and produces no fan noise — quiet and serene. Relying on natural convection physics, air circulates and exchanges heat, with warmth diffusing from top to bottom, enabling the entire room to reach a comfortable, balanced temperature uniformly and rapidly within 20–30 minutes.
Equipped with a microcomputer intelligent control system supporting smart variable frequency, the LCD digital display integrates temperature control and timer functions. Users can freely set scheduled on/off times and enjoy 7×24-hour smart programming for pre-scheduled heating.

Multi-Layer Safety Protection
1. Constant Temperature Auto-Stop
When the set temperature is reached, the device automatically stops heating and maintains the temperature. Once the temperature drops below the threshold, it resumes heating automatically.
2. Cover Detection Auto-Shutdown
If the upper part of the unit is covered or blocked, and the temperature reaches the limit, the device automatically shuts down to prevent overheating and fire hazards.
3. Tip-Over Auto-Shutdown
In case of accidental tipping or falling, the unit immediately cuts off power. The system automatically shuts down when the heater is tilted, ensuring comprehensive safety protection.
High-Temperature Alloy Thin-Layer Heating Technology
The unit adopts a nickel-chromium alloy thin-layer heating structure. It heats up rapidly upon startup. The alloy base material is corrosion-resistant and oxidation-resistant, maintaining stable power output over long-term operation without degradation. The heating components are highly durable.
Compared to traditional electric heating components, this technology offers higher heat utilization efficiency and greater energy savings for daily use.
Installation is flexible and convenient — choose between freestanding placement or wall-mounted installation. Simply connect to a power outlet for immediate use.
