A digital benchmark recognized by CCTV, and a digital factory with an annual output of 500,000 units — a hidden champion in gas water heater manufacturing nestled on the West Bank of the Pearl River Estuary.

Located in Zhongshan, there is an enterprise that sells no products under its own brand yet acts as the technical partner behind the product lines of many mid-to-high-end kitchen and bathroom brands nationwide. This enterprise is Zhongshan Yangzi Electric Industry Co., Ltd.

I. Who Is Yangzi? We Have Focused on One Single Business for Over 20 Years

Zhongshan Yangzi Electric Industry Co., Ltd. is situated in Zhongshan, the heart of the Guangdong-Hong Kong-Macao Greater Bay Area. Unlike consumer-facing brand operators, Yangzi holds a clear and focused positioning: a professional OEM/ODM manufacturer specializing in large-capacity gas water heaters.

Starting from export OEM in the early days, then strategically focusing on customized production for domestic mid-to-high-end brands, and later certified as a National High-tech Enterprise and one of the first batch of enterprises in the industry to pass mandatory 3C certification, Zhongshan Yangzi has consistently adhered to the path of specialized development and continuous upgrading. At present, its new factory boasts an annual production capacity of 500,000 units, with a full range of large-capacity models from 18L to 28L. Supported by stable and reliable manufacturing capabilities, it serves as a solid backing for numerous kitchen and bathroom brands competing in the high-end gas water heater market.

II. Cutting-edge Technologies: Breaking Core Barriers of Large-capacity Gas Water Heaters

Large-capacity gas water heaters are not merely scaled-up versions of ordinary units. They require comprehensive reconstruction of core technologies including combustion systems, constant temperature control, heat exchange efficiency and safety protection, resulting in extremely high R&D thresholds.

For more than 20 years, Zhongshan Yangzi has concentrated on this field and assembled an experienced R&D team, over half of whose members have more than ten years of industry experience. The team keeps making breakthroughs in four core areas: high-efficiency combustion, precise constant temperature control, efficient heat exchange and all-round safety protection, forming a complete, mature and stable proprietary technical system. Every performance indicator, including stable high water flow output, zero interference during simultaneous multi-point water use, low-noise operation, efficient heat exchange and long service life, has undergone repeated verification and iteration. The products effectively address core pain points of large-capacity units in scenarios such as high-rise residences, large apartments and simultaneous hot water supply for multiple bathrooms, boosting market competitiveness at retail terminals.

III. Digital Intelligent Manufacturing: Six Major Systems Build Full-Chain Quality Barriers

In 2022, CCTV-13 Morning News covered the high-quality development of manufacturing in Zhongshan and featured Zhongshan Yangzi Electric as a benchmark enterprise for digital transformation in a special report.

Taking this as a new starting point, Yangzi has further deepened its layout of digital intelligent manufacturing. Six major information management systems — CRM, ERP, PLM, APS, MES and WMS — have been fully deployed to realize data connectivity and intelligent collaboration across the whole industrial chain covering R&D, production, supply, sales and after-sales services. With deeply integrated systems, traceable production processes and verifiable data, the company strictly complies with the ISO9001 quality management system. Every product follows standardized procedures and leaves complete traceable records from design to delivery, laying a solid foundation for quality through digital capabilities.

IV. Foundation of Quality: Reliable Products Built on Stringent Standards

Quality is the lifeline of manufacturers, and Zhongshan Yangzi always prioritizes quality control throughout R&D, supply chain, production and testing. In terms of regulatory compliance, 3C certification has entered its strictest supervision era in 2026. Years ahead of the tightening policies, Yangzi has long adhered to the highest certification standards: compliance assessment at the early R&D stage, 100% certified core components, online real-time inspection in full production procedures and standardized in-house certification management. The company voluntarily accepts supervision and inspections, turning compliance capacity into a core guarantee of consistent product quality.

On this basis, the factory is equipped with professional testing equipment for gas pipeline leak detection, water circuit leakage inspection and combustion performance evaluation, implementing multiple rigorous inspection procedures. Safety, stability and durability are embedded into every product, making our quality not merely meet certification requirements but surpass them.

V. Win-win Cooperation with Brands: More Than an OEM, Your Technical Partner

Easy sales promotion, low after-sales failure rate, complete qualification certificates, stable delivery and controllable profit margins — these constitute the core value Yangzi delivers to partner brands. Unlike basic label pasting OEM services, we position ourselves as your dedicated technical partner and offer full-lifecycle support: At the front-end, we share our mature large-capacity water heater technologies to cut your R&D costs and speed up product launch; During mass production, a dedicated team strictly controls production progress and delivery schedules to ensure consistent bulk supply; At the back-end, we provide systematic technical training and after-sales support to reduce your operating expenses.
