Product Description

Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Thanks to the innovative design and advanced structure, our vacuum boiler is engineered to deliver dual hot water outputs. Experience the convenience of dual-temperature hot water supply simultaneously, facilitated by a versatile dual-circuit or an independent single-circuit system.
High thermal efficiency: In a fully enclosed vacuum chamber, the heat exchange process circulates seamlessly. Constructed from premium imported stainless steel, this ensures superior heat transfer efficiency. Our heat exchanger is not only highly efficient but also remarkably energy-saving.
Absolute safety: Our boiler operates at a consistent negative pressure, eliminating any explosion risks. Equipped with an array of safety features such as temperature sensors, safety valves, overheat protection, and vacuum control switches, we prioritize comprehensive protection against safety hazards.

Intelligent control: Featuring cutting-edge digital control with an intuitive LCD screen displaying in Chinese, our advanced control system allows for precise temperature settings. Real-time display of parameters such as furnace temperature and vacuum degree, automatic logging of combustion time and operational faults, ensures simplicity in operation and facilitates autonomous functioning.
Eliminate the trouble of registration procedures: Our pre-assembled boiler, designed to function under negative pressure, is inherently safe from expansion or explosion, thus exempting it from supervisory inspection. This advantage significantly minimizes your installation costs by bypassing complex registration processes.

This advantage significantly minimizes your installation costs by bypassing complex registration processes.
Energy saving: Featuring a minimal heat medium water volume and efficient heat exchange within a vacuum chamber using negative pressure steam, our system achieves desired water temperatures in under ten minutes without preheat losses, showcasing remarkable energy efficiency and savings.
Long life: Crafted from top-grade stainless steel for optimal heat transfer and corrosion resistance, our heat exchanger ensures rapid heat conduction. Flanged pipe ends facilitate easy maintenance, while the vacuum-sealed furnace body prevents corrosion and scaling, extending the service life considerably.
Insulation structure: With a robust 100mm double-layer insulation, our design minimizes the boiler's external touch temperature to that of the room, enhancing safety and significantly boosting thermal efficiency.
Imported low-nitrogen burner: Delivering efficient combustion with low noise and minimal exhaust emissions, our burner meets the stringent standards of the country's top-tier environmental requirements.
