Product Description

Gas Vacuum Hot Water Boiler
One machine for multiple purposes: This innovative vacuum boiler, with its meticulously crafted design and structure, is your versatile solution for dual hot water needs. Featuring dual hot water outputs, it can simultaneously deliver water at varied temperature levels, thanks to its dual-circuit system. The ingenious design allows for a single-circuit system to work independently, offering you unparalleled flexibility and convenience.
High thermal efficiency: Experience the pinnacle of heat exchange with our boiler's completely closed vacuum chamber. Crafted from top-tier imported stainless steel, it ensures superior heat transfer efficiency. The heat exchanger is an engineering marvel, designed for back-and-forth circulation that maximizes thermal efficiency while delivering remarkable energy savings.
Absolute safety: Safety is our utmost priority. Our boiler operates in a consistent negative pressure state, eliminating any risk of explosion. Equipped with an array of safety measures like temperature sensors, safety valves, overheat protection, and vacuum control switches, it ensures comprehensive protection from potential hazards, providing peace of mind with every use.
Intelligent control: Step into the future with our advanced digital control system. With an easy-to-read LCD screen and Chinese display, you have complete control to set temperatures freely. Real-time parameters such as furnace temperature and vacuum degree are displayed, while combustion times and operation faults are automatically logged. Simple operation means you can enjoy a hands-free experience.
Eliminate the trouble of registration procedures: Skip the hassle of tedious registration procedures. Our boiler operates under negative pressure, ensuring no risk of expansion or explosion, freeing you from supervision and inspection requirements. Enjoy a streamlined installation process that minimizes costs and maximizes efficiency.
Energy saving: Revolutionize your energy consumption with minimal heat medium water. The efficient heat exchange in our vacuum chamber, using negative pressure steam, quickly produces warm water at your desired temperature in under ten minutes, significantly reducing preheating loss and boosting energy savings.
Long life: Built for longevity, the heat exchanger is crafted from stainless steel, known for its outstanding heat transfer and corrosion resistance. Flange-connected pipe ends simplify maintenance and replacement. The vacuum state of the furnace body and absence of corrosion or scale, along with protected heated tube bundles, ensure an extended service life.
Insulation structure: Our advanced 100mm double-layer insulation structure enhances both safety and thermal efficiency. By reducing the boiler's external touch temperature to room levels, it provides a safer environment while boosting the boiler's overall performance.
Imported low-nitrogen burner: Our imported burner is designed for high-efficiency combustion with minimal noise and emissions. It meets the stringent standards of first-class areas, ensuring compliance and environmental responsibility with every operation.
