Xunji instant electric water heater, inspired and guided by the school motto of Tsinghua University "Self-improvement and Integrity", a safe and efficient instant electric water heater with a new non-metallic heating element was born in China. This is an epoch-making event in my country's electrical industry and a revolutionary innovation in China's electric heating industry. The core heating element of the Xunji instant electric water heater is smelted with natural crystal ore, which is made by a scientific and rigorous Western with a special process. Its unique natural hydroelectric separation structure is a major technological innovation to improve heating efficiency and safety performance. Its outstanding advantage of non-scaling is the technical guarantee that is not subject to the boundaries of regional water quality.

Xunji instant electric water heater has always been based on wisdom, elegance and innovation, abiding by the cultural concept of Seiko Tao, committed to product innovation and new technology research and development, insisting on quality, and pursuing the perfection of quality and design. It deeply affected the development of the industry and led a change in bathing culture.
Xunji Technology carries the weight of people's happiness and stands proudly between heaven and earth. Think: Your happiness is our pursuit. For the sake of our original intentions, we only strive to be the first. Seiko quality is what we abide by, and technological innovation leads the green, low-carbon and intelligent future. Xunji Technology is the creator of dream life.

QNH non-metallic heating element is made of high-purity thermal conductive silicon crystal tube made by smelting natural crystal ore. A layer of uniquely formulated nano-scale heating material is attached to the outer wall of the tube by a high-temperature sintering method and a series of sophisticated processes. The outer wall of the silicon transistor is integrated. The heat energy is quickly transferred to the water in the tube through the silicon transistor with high insulation, high thermal conductivity and high grade, and the ideal water outlet temperature can be obtained through adjustment.

QNH silicon crystal heating element has better quenching and heat resistance and high pressure bearing performance. The high-purity thermally conductive silicon crystal tube with a silicon dioxide content of up to 99.99% guarantees the natural hydroelectric separation of the heating structure, faster heat conduction, and higher thermal efficiency High, no scale, longer service life. The application of QNH silicon transistor heating technology will further consolidate the advantages of non-metallic hydroelectric completely separated heating technology in the instant electric water heater market, allowing consumers to truly feel the safety and bathing pleasure of a new heating era.
