The Devotion fully premixed low-NOx condensing hot water boiler features an integrated inline tube structure with a compact design and small footprint. The heat exchanger is made from 316L stainless steel, known for its corrosion resistance and long service life. With an operating efficiency of up to 108%, this boiler employs fully premixed combustion, reducing nitrogen oxide emissions to below 30mg/m³. The atmospheric design eliminates the need for regulatory inspections, making it suitable for installation in basements, rooftops, or green spaces. It is widely used in projects like "coal-to-gas" conversions and "low-NOx retrofits," as well as for heating and hot water in small and medium-sized businesses.

Low-NOx Retrofit:
Ideal for small to medium-sized central heating retrofits in urban areas where low-NOx boiler replacement is required.

Commercial Applications:
Perfect for hotels, restaurants, commercial buildings, and leisure facilities.

Public Institutions:
Provides heating and hot water for small-scale applications in schools, hospitals, and office buildings.

Product Structure

• Intelligent Controller:
  Offers intelligent control and a multi-stage system that automatically adjusts load proportionally for energy-efficient operation.

• DC Variable Frequency Fan:
  Automatically adjusts speed and airflow according to load changes, ensuring stable output that matches load fluctuations.

• Zero Gas Pressure Valve:
  Automatically adjusts gas flow based on load changes to maintain a constant air-fuel ratio, even during a variable load operation.

• Stainless Steel Finned Tube:
  Maximizes heat exchange area and enhances thermal conductivity. The design prevents corrosion and scale buildup.

• Heat Exchanger:
  Made from 316L stainless steel, known for high heat transfer efficiency, superior corrosion resistance, and long service life.

• Metal Fiber Burner:
  Utilizes fully premixed surface combustion technology, which distributes the flame into numerous small, evenly spaced flames, lowering combustion temperature and reducing NOx formation.

Product Features

• Compact Design, Small Footprint:
  The integrated system is easy to transport and quick to install, reducing setup time.

• Modular Design:
  The modular design allows for easy disassembly and reassembly, making it suitable for spaces with restricted access. It can be installed close to the point of use, eliminating the need for a dedicated boiler room and reducing flue investment.

• Lightweight Design:
  The lightweight equipment is easy to transport and install, ensuring quick setup while maximizing overall project efficiency.

• Comprehensive Installation Documents:
  Comes with complete installation guides and pre-adjusted settings for easy on-site adjustments after installation.

• Strict Factory Testing:
  The boiler undergoes extensive testing before shipping, including pressure stability, gas circuit sealing, and a 30-minute full-load burn test.

Full Premixed Surface Combustion Technology

• NOx Emissions Below 30mg/m³:
  Fully premixed natural gas and air combustion ensures optimal efficiency and reduces NOx emissions to below 30mg/m³, far surpassing stringent national emission standards.

High-Efficiency Multi-Stage Heat Exchange / Condensing Technology

• 108% Efficiency, More Hot Water:
  After fully premixed combustion, the high-temperature flue gas passes through multiple heat exchange stages, reaching a low-temperature condensing zone where finned tubes absorb both sensible and latent heat, achieving 108% efficiency.

Stainless Steel Finned Tube Heat Exchanger

• Corrosion Resistant, Anti-Scaling, Long Lifespan:
  Made from 316L stainless steel, this heat exchanger offers three times the thermal conductivity of regular steel. Its surface forms a protective film that enhances corrosion resistance, making it long-lasting and durable.

Multiple Safety Protection Systems

• Flameout Protection:
  Monitors the burner for flame loss using ion probes, ensuring the system shuts off the gas supply if no flame is detected.

• Over-Temperature Protection:
  Automatically shuts down the boiler if water temperature exceeds 95°C to prevent damage.

• Flue Gas Temperature Protection:
  Shuts down the system if flue gas temperatures exceed safe limits.

• Gas Pressure Protection:
  Ensures stable flame conditions by monitoring gas pressure, preventing flame loss or re-ignition failures.

• Gas Leak Protection:
  Automatically shuts off the gas supply in the event of a gas leak.

• Anti-Freeze Protection:
  Automatically heats the boiler to prevent freezing when water temperature drops to 4°C (requires boiler to remain powered).

Intelligent Touch Control System

• Timed and Constant Temperature Control, 24/7 Hot Water:
  Features a modern 7-inch color touchscreen that simplifies control with an intuitive interface.

• Constant Temperature Technology:
  Automatically adjusts boiler output power based on heating demand, saving 20-30% more energy than traditional systems.

• Automatic Fault Alarms:
  Real-time alerts and error messages help prevent accidents and ensure safe operation.

• Remote Monitoring:
  The system offers real-time monitoring and remote control capabilities via the Internet, ensuring optimal performance at all times.

Multi-Unit Linkage Control System

• Smart Operation for Energy Savings and Safety:
  Multiple boilers can be linked together for modular operation, automatically adjusting output based on demand to avoid overproduction and improve efficiency.

• Balanced Workload:
  The system balances workloads across all units, ensuring stable operation even during maintenance.

• Remote Monitoring and Alarms:
  Real-time monitoring and alerts enhance safety and flexibility, ensuring efficient and reliable operation at all times.
