Low NOx Condensing Gas Boiler

Baedin factory's China Low NOx Condensing Gas Boiler Six ratings: 20 kW, 24 kW, 28 kW, 32 kW, 36 kW, and 40 kW, covering heating areas from 80 m² to 250 m². Select based on floor area, heat load, and local emission standards.

Applicable Environments & Operational Superiority

Baedin's China Low NOx Condensing Gas Boiler is widely suitable for residential heating, underfloor systems, and radiators – especially in first-tier cities and key environmental protection zones with strict boiler emission requirements. With regulations tightening across China – Beijing now requires NOx ≤70 mg/kWh, and some areas demand ≤30 mg/m³ – this boiler is specifically designed to meet such standards, ensuring easy compliance. The condensing effect peaks with low return water temperatures, making underfloor heating the ideal match for maximum savings.

Core Advantages

Ultra-Low NOx Emissions – Low-NOx combustion technology reduces emissions to ≤30 mg/m³, far exceeding national limits – cutting NOx by over 58% against the strictest standard.
High Efficiency – Fully premixed condensing technology delivers 107%–108% thermal efficiency, recovering latent heat from flue gas and saving over 20% gas compared to conventional boilers.
Clean & Green – CO emissions are drastically reduced. A single unit cuts annual NOx by ~79% and CO₂ by 576 kg – equivalent to planting 208 pine trees per year.
Stable & Comfortable – Low NOx Condensing Gas Boiler is fully premixed proportional modulation ensures precise temperature control, rapid hot water response, and ±1°C accuracy even during multi-point use.
Flue Gas Recirculation – A portion of low-temperature flue gas is reintroduced for secondary combustion, further lowering flame temperature, suppressing NOx, and improving efficiency – a key feature distinguishing this model from standard condensing boilers.
Smart Safety – LED display, heating/DHW priority, frost protection, anti-lock, dry-burn, over-temperature, low-pressure, flame-out, and 3Bar relief valve ensure comprehensive protection.
