Core Technology Advantages
Proprietary Cast Aluminum Heating System
Featuring an advanced M-shaped heating tube and optimized vertical water channel design, the system delivers efficient heat transfer, stable performance, and enhanced durability. The extended heating path increases water-to-heating contact for more effective heating while reducing localized thermal load, helping extend product lifespan. Combined with a streamlined 11–12 circuit vertical flow structure, the design minimizes water resistance, improves flow rate under consistent pressure conditions, and provides a more comfortable and stable hot water experience.
Intelligent Temperature & Flow Control System
Intelligent stepper motor technology dynamically adjusts water flow and heating power based on inlet temperature and set temperature. It automatically optimizes flow to maintain stable hot water output, eliminating the need for manual mixing valve adjustment. This ensures precise temperature control, maximum usable flow within available power, and a more consistent shower experience in all conditions.
Easy-to-follow installation diagrams and wiring layouts designed for fast, safe, and efficient product setup. Includes water connection, electrical configuration, and mounting guidance for different application environments.
Comprehensive technical data covering product dimensions, power options, heating performance, water flow capacity, and electrical requirements to support accurate product selection and project planning.
Detailed operating instructions and maintenance guidance to ensure safe operation, optimal performance, and long-term reliability. Includes safety precautions, troubleshooting information, and daily usage recommendations.
