Commercial Vacuum Hot Water Boiler D6 Product Advantages

  • High Efficiency and Energy Savings

    The D6 series uses fully premixed surface combustion, ensuring optimal fuel-air mixture for efficient combustion. Its compact design, combined with a short combustion chamber, ensures even heat distribution and superior heat transfer, maximizing overall efficiency.

  • Low Emissions and Environmental Protection

    The dual combination of a condenser and deep cooler reduces flue gas temperature to 20°C, significantly lowering CO₂, SO₂, and nitrogen oxide emissions. It eliminates the white smoke issue common in gas boilers, making it eco-friendly and ideal for residential areas.

  • Reduced Installation and Operating Costs

    The compact design and winged tube technology reduce the boiler’s size and lower construction costs. The low exhaust temperature allows the use of PVC chimneys, saving on installation expenses, and treated condensate can be reused, minimizing water consumption.

  • Smart and Modular Control

    The D6 series features advanced intelligent controls with high automation and a user-friendly interface. The modular design allows for multi-boiler control, optimizing heating load and ensuring efficient operation, while the vacuum maintenance system enhances performance.
