Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Revolutionize your water heating experience! Thanks to its unique and innovative design, our vacuum boiler offers dual hot water outputs, providing versatility with different temperature settings. Whether you prefer a dual-circuit system or a single-circuit operation, both options work independently, ensuring that you receive the precise combination of hot water you need, exactly when you need it.
High thermal efficiency: Step into the future of energy efficiency! With heat exchange processes occurring within a fully sealed vacuum chamber crafted from premium imported stainless steel, our heat exchanger promises unmatched heat transfer efficiency. This results in remarkable energy savings, making it not only a smart choice for your home but also an environmentally friendly one.
Absolute safety: Safety is our top priority. The boiler operates under a constant negative pressure, eliminating any risks associated with explosions. Equipped with state-of-the-art safety features like temperature sensors, safety valves, overheat protection, and vacuum control switches, we have meticulously addressed every potential safety concern to ensure your peace of mind.
Intelligent control: Experience the pinnacle of user-friendly technology with our cutting-edge digital control system. Featuring an LCD screen with a Chinese display, it allows for effortless customization of temperature settings. Real-time displays of furnace temperature, vacuum levels, and operational statuses keep you informed, while automated fault recording and no-operator-needed functionality streamline your experience.
Eliminate the trouble of registration procedures: Simplify your installation journey! Our boiler, which functions under negative pressure, bypasses the need for extensive supervision and inspection. Relieve yourself from cumbersome registration procedures, reducing costs and expediting the installation process, bringing you convenience without compromise.
Energy saving: Embrace efficiency and sustainability with our cutting-edge design! Utilizing a minimal amount of heat medium water and conducting heat exchange in a vacuum chamber with negative pressure steam, our boiler quickly delivers warm water at your desired temperature within just ten minutes, minimizing preheating losses and maximizing energy conservation.
Long life: Invest in durability with our stainless steel heat exchanger, renowned for its superior heat transfer capabilities and resistance to corrosion. The flange-connected pipe ends facilitate easy maintenance, while a vacuum-sealed furnace body prevents corrosion and scaling. The design ensures the heated tube bundle avoids direct contact with flames or flue gases, significantly extending the boiler's service life.
Insulation structure: Our boiler boasts a 100mm double-layer insulation structure that keeps its external surface at room temperature, enhancing safety while significantly boosting thermal efficiency. Enjoy the perfect combination of safety and performance in one innovative design.
Imported low-nitrogen burner: Optimize your heating system with our imported low-nitrogen burner, featuring high-efficiency combustion. Enjoy the benefits of minimal noise and low exhaust emissions, ensuring compliance with the stringent standards of first-class national environmental regulations.
