Baedin: Your Source Manufacturer for Secondary-Heat-Exchange Condensing Combi Boilers.As the original source manufacturer of Baedin secondary-heat-exchange condensing gas combi boilers, we fully support OEM/ODM customization. Powered by our proprietary dual-stage heat exchange structure, our boilers recover latent heat from flue gases to achieve a thermal efficiency of over 107%. Meeting the highest Tier-1 energy efficiency standards, they perfectly fulfill dual needs for whole-house underfloor heating and constant-temperature domestic hot water.

We offer flexible cooperation models including bulk purchasing, customized power ratings, bespoke appearance panels, and tailored control systems.

Our products feature low-NOx premixed combustion and multiple safety modules (anti-freeze, dry-burn protection, overheating protection, and water pressure monitoring). Compatible with mainstream natural gas sources, they are ideal for residential homes, homestays, and small commercial heating scenarios.

By cutting out middleman markups, we provide direct factory pricing, technical drawings, inspection reports, and private-label (OEM) services. With a stable supply chain and support for large-scale engineering projects, we offer a one-stop, high-cost-performance sourcing solution for domestic and international buyers across diverse heating projects and retail channels.
