Devotion's fully premixed low-NOx condensing hot water boiler features an inline tube structure that is compact and space-saving. The heat exchanger is made from 316L stainless steel, offering excellent corrosion resistance and long service life. With an efficiency of up to 108%, the fully premixed combustion system emits NOx levels below 30mg/m³. Its atmospheric design eliminates the need for regulatory inspections, allowing for installation in basements, rooftops, or green spaces. This boiler is widely used in "coal-to-gas" conversions, "low-NOx retrofits," and for heating and hot water in small and medium-sized enterprises.

  The lightweight equipment is easy to transport and install, ensuring quick setup and project completion.

• Complete Installation Documentation:
  Comes with comprehensive installation manuals for easy assembly. Pre-adjustments are made before shipping, allowing for quick on-site tuning.

• Rigorous Factory Testing:
  Every unit undergoes extensive testing, including pressure stability, gas circuit sealing, and a 30-minute full-load burn test before leaving the factory.

Fully Premixed Surface Combustion Technology

• NOx Emissions Below 30mg/m³:
  Fully premixed natural gas and air combustion ensures optimal combustion, effectively reducing NOx emissions to below 30mg/m³, well below the strictest national emission standards.

High-Efficiency Multi-Stage Heat Exchange / Condensing Technology

• 108% Efficiency, More Hot Water:
  After combustion, the high-temperature flue gas undergoes multiple heat exchange stages before reaching the low-temperature condensing zone. The finned tubes absorb both sensible heat and the latent heat released from steam condensation, achieving an efficiency of up to 108%.

Stainless Steel Finned Tube Heat Exchanger

• Corrosion Resistant, Anti-Scaling, Long Lifespan:
  Made from 316L stainless steel, this heat exchanger provides excellent heat transfer and corrosion resistance, extending its service life.

Multiple Safety Protection Systems

• Flameout Protection:
  Detects the absence of a flame using ion probes and automatically shuts off the gas supply.

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

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

• Gas Pressure Protection:
  Monitors gas pressure to ensure stable flame conditions, preventing flame loss or re-ignition issues.

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

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

Intelligent Touch Control System

• 24/7 Constant Temperature Hot Water:
  The system features a 7-inch color LCD touchscreen, providing an intuitive interface and simplifying control. Functions include variable speed pump control, multi-loop control, time programs, and temperature settings.

• Constant Temperature Technology:
  Automatically adjusts boiler output according to heating demand, saving 20-30% more energy compared to traditional boilers.

• Automatic Fault Alarms:
  Real-time monitoring detects abnormal system parameters, triggering alarms to prevent accidents.

• Real-Time Monitoring:
  Monitors boiler temperature, pressure, flow, and pump status, allowing for remote control and monitoring via the internet.

Multi-Unit Linkage Control System

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

• Balanced Workload:
  The system balances workload across all units, ensuring stable operation even during maintenance, with uninterrupted heating.

• Remote Monitoring and Alerts:
  Real-time monitoring and alert systems enhance safety, ensuring flexible and efficient operation at all times. Remote management is available via the IoT platform.
