1. Innovation in Materials and Processes
Popularization of High-End Materials: In demanding environments (such as instant water heaters, dishwashers), the proportion of materials with better corrosion resistance and anti-scaling properties (such as 316L stainless steel, titanium tubes, Inglise 800) has increased to extend lifespan and enhance reliability.
Surface Treatment Technology: Utilizing technologies like Teflon coating and ceramic coating to enhance anti-corrosion and anti-scaling capabilities, especially suitable for areas with hard water.
Structural Optimization: Developing more precise fin-like and corrugated structures to increase heat dissipation area and improve heat exchange efficiency (particularly important in heaters and instant products).
2. Enhancement of Energy Efficiency and Power Density
Higher power density: Achieve higher power output while maintaining or even reducing the volume, to meet the ultimate demand for “instant hot water” of instant heating products (such as instant water dispensers and faucets).
Energy efficiency design: Optimize the layout of internal heating wires and heat-conducting media to reduce heat loss, enabling more efficient conversion of electrical energy into effective heat energy, in line with increasingly strict energy efficiency standards worldwide.
3. Integration of Intelligence and Precise Temperature Control
Integration of Sensing and Control: The heating tube is no longer an independent component; instead, it is deeply integrated with NTC temperature sensors, MCU (microcontroller), and solid-state relays. This enables precise PID temperature control, real-time power adjustment, and multiple temperature protection.
Application of Variable Frequency Technology: In high-end electric water heaters and instant heating products, the heating power can be adjusted continuously by regulating the input current frequency, achieving “on-demand heating”, avoiding temperature fluctuations, and being more energy-efficient and comfortable.
Internet of Things Connection: As part of smart home appliances, users can remotely control or set heating modes, and the system can also perform self-diagnosis and fault warning.
4. The Ultimate Pursuit of Safety
Standardized multiple protection: Besides the basic thermostat and thermal fuse, features such as anti-dry-burn sensors, leakage protection, pressure switches, and water and electricity separation technology have become standard equipment for mid-to-high-end products.
Essential safety design: For instance, the promotion of the use of PTC ceramic heating elements (with self-limiting temperature characteristics, the temperature will not continue to rise indefinitely) to replace traditional metal heating tubes in certain areas (such as air-cooled bathroom heaters and some warm air blowers) has improved the safety level from a fundamental principle.
5. Specialization and Scene Segmentation
Develop specialized heating tubes for specific operating conditions of different household appliances. For example:
Silent type: Suitable for environments sensitive to noise (such as humidifiers used in bedrooms).
Explosion-proof type: Suitable for special environments where there may be flammable gases (such as certain industrial-designed water heaters).
Quick-start type: Suitable for steam products that require instantaneous high temperature.
