As an efficient and convenient heating device, electric heating film is gaining increasing popularity. However, proper installation and usage are critical to its performance and safety. Below is a detailed overview of relevant knowledge regarding electric heating film installation and usage. 

 I. Pre-Installation Preparation 

**Environmental Assessment** 

Before installation, conduct a comprehensive inspection of the installation environment. Ensure the surface is flat, dry, and clean, free of cracks, holes, or other defects. For floor installation, the ground bearing capacity must meet requirements; for wall installation, the wall structure must be stable. Meanwhile, the ambient humidity should be within a suitable range to avoid excessive moisture affecting performance and service life. 

**Tool and Material Preparation** 

- **Tools**: Essential heating film cutter for precise cutting to size; insulating tape for insulation treatment of wire connections (preventing leakage); wire strippers for easy wire insulation removal. Auxiliary tools such as tape measures and levels are also needed to ensure accurate installation positions. 

- **Materials**: Electric heating film (select specifications and power based on installation space); thermostat (key component for temperature control, requiring reliability and precision); sensor (for ambient temperature sensing and feedback to the thermostat); wires (compliant with safety standards and current-carrying capacity); terminal blocks (for secure connection between wires and heating film). Additionally, structural adhesive (for fixing the heating film), expansion screws (for wall mounting), and cable trays (for wire organization and protection). 

**Safety Protection** 

Equip with insulating gloves (to prevent electric shock), safety helmets (to protect against falling objects), and anti-static shoes (to avoid static damage to the heating film) for safe installation. 

 II. Installation Process 

**Layout Design Planning** 

Based on room size and usage needs, carefully draw a heating film layout design. Determine placement and routing to ensure uniform heat distribution, avoiding heating dead zones. For example, in bedrooms, lay around beds; in living rooms, align with furniture layout. 

**Wall/Floor Preparation** 

For wall installation: Clean the wall with detergent to remove dust and oil, then check flatness; level uneven areas with structural adhesive. For floor installation: Clean the ground, then lay insulation material (e.g., polystyrene foam board, 2-5 cm thick) to reduce downward heat transfer and improve thermal efficiency. 

**Thermostat and Sensor Installation** 

Fix the thermostat at an accessible and observable position, typically 1.3-1.5 meters above the ground. Install the floor temperature sensor as per instructions, usually 10-20 cm from the heating film edge, then perform initial wiring. 

**Heating Film Laying** 

Lay the heating film carefully on insulation material (floor) or walls per the design. Avoid folding or scratching; maintain a 5-10 mm gap between films. 

**Fixing and Wiring** 

Secure the heating film with fasteners (e.g., dedicated clips or structural adhesive). Connect wires to the heating film and thermostat per the circuit diagram, ensuring tight joints, which are then tightly wrapped with insulating tape to prevent leakage. 

**Inspection and Testing** 

After installation, conduct a comprehensive circuit test. Use a multimeter to check for continuity, ensuring no short circuits or open circuits. Inspect for surface damage on the heating film and secure connections. 

 III. Usage Methods and Precautions 

**Proper Startup** 

For first use, set the thermostat to a low temperature (e.g., 18℃), then power on. Wait and observe if the heating film heats normally and the thermostat displays accurately. If normal, gradually increase the temperature as needed. 

**Temperature Adjustment** 

Adjust the thermostat flexibly based on season, time, and personal comfort. Generally, a comfortable indoor temperature in winter is 18-22℃. Lower the temperature when away or sleeping to save energy. 

**Usage Taboos** 

Prohibit placing heavy objects on the heating film (to avoid damage); prevent water splashing on the surface (to avoid leakage); do not disassemble or modify the heating film/thermostat—contact professional maintenance for faults. 

 IV. Maintenance Essentials 

**Regular Inspection** 

Inspect the heating film and temperature control system quarterly. Check for surface wear/cracks, wire aging/damage, and thermostat sensitivity/accuracy. 

**Cleaning and Maintenance** 

Periodically wipe the heating film surface with a clean soft cloth to remove dust. Avoid corrosive cleaners to prevent damage. Keep the installation environment clean to avoid dust accumulation affecting heat dissipation. 

**System Monitoring** 

Daily, observe operation (e.g., uniform heating, normal heating rate). Investigate abnormalities promptly. Record power consumption data to analyze performance and detect potential issues early. 

Proper installation, rational usage, and careful maintenance of electric heating film can fully leverage its advantages, providing a warm, comfortable, and safe living environment. It is hoped this guide helps users utilize electric heating film effectively.
