Electric heating film, as a modern innovation, evolved from carbon crystal heating film technology. Carbon crystal-based systems were widely adopted in Europe and North America as early as the 1970s, and introduced into China in the 1990s. However, due to their high energy consumption and China’s energy constraints at the time, their development was relatively slow.
The emergence of graphene, a revolutionary material with exceptional physical properties, has reshaped the industry and opened new possibilities for innovation. Graphene-based heating films are now widely applied in various sectors and increasingly recognized by customers worldwide.
What is Graphene Heating Film?
Graphene heating film is a type of composite film that generates heat when electricity is applied. In a heating system, the film acts as the core heat source, radiating warmth evenly into the space. Unlike traditional point or line heat sources like water pipes, heating cables, or carbon fiber wires, graphene heating film offers a much larger heating surface—resulting in more efficient and consistent radiant heating.
At CCT, we control the entire manufacturing process in-house—from graphene powder preparation to conductive ink formulation and film production—backed by numerous patented technologies. But what sets graphene heating film apart?
Key Advantages of Graphene Heating Film
1. Fast & Even Heating
Graphene offers outstanding electrical and thermal conductivity. The heating film made from it distributes heat across its entire surface quickly and evenly. It creates a vertical temperature gradient—warmer at the feet, cooler near the ceiling—optimizing comfort while keeping both temperature and humidity within the most comfortable range for the human body.
2. Exceptional Stability & Longevity
Traditional electric underfloor heating systems often suffer from significant heat decay within 1–2 years, increasing electricity costs. Water-based systems, too, degrade over time due to pipe quality and scale buildup, requiring regular maintenance. Graphene heating film, by contrast, is highly stable, requires no maintenance, and can last over 50 years—essentially matching the building’s lifespan.
3. Energy Efficiency
Our CCT graphene heating film achieves a heat conversion efficiency of over 99.99%, significantly higher than conventional floor heating systems. That means nearly all input electricity is converted to heat with minimal loss. Compared to traditional water heating with centralized control, graphene heating allows for zoned, room-by-room scheduling, reducing overall energy usage by up to 30%.
4. Healthy & Comfortable Environment
Conventional systems like hot water heating or resistive heaters often lead to dry indoor air—causing discomfort such as dry throat, dizziness, or chest tightness. Some mistakenly assume that all electric heating causes dryness, but this is not scientifically accurate.
Graphene heating film uses low-temperature far-infrared radiation, promoting even warmth without drastically reducing indoor humidity. It provides a comfortable, healthy heating experience—without the side effects of air drying or thermal imbalance.
How to Choose a True Graphene Heating Film?
Not all products labeled as “graphene” in the market actually contain genuine graphene materials. To ensure product quality and authenticity, consider the following:
-
Request official test reports: Look for certifications from recognized authorities such as CCC, CE, UL, and RoHS.
-
Choose reputable brands: Select suppliers with technical backgrounds and a proven track record. Be cautious of low-priced, inferior alternatives.
-
Check after-sales support and warranty: Reliable companies offer clear service policies and technical support.
It’s easy to verify: simply ask the manufacturer for valid third-party testing documentation.
Smarter Way to Heat
Graphene electric heating film represents not only a technological upgrade, but a shift in how we think about indoor heating. If you’re considering underfloor heating, it’s crucial to understand the material behind it, and evaluate factors like performance, certifications, and brand strength.
Choosing graphene heating film is more than a heating solution—it’s a commitment to a smarter, greener, and healthier lifestyle.
