Vacuum boilers operate under negative pressure conditions, hence they are prone to explosions and are *unqualified for spot inspections.

2. The successful separation of the high-temperature and high-pressure areas of the boiler's load-bearing steel plate, which extends the boiler's lifespan by 2-3 times, with a designed lifespan exceeding 30 years.

The overall design is scientifically, reasonably, and flexibly structured, saving up to 50-70% of land space.

4. Heat transfer is conducted within the boiler's body, resulting in an overall efficiency of over 91%. Once activated, the system can produce 70-80℃ hot water within 2-3 minutes, significantly reducing the pressure build-up time and energy waste.

5. Fully automated control, capable of implementing intelligent, unmanned operation, or remote network control.

6. Equipped with a stainless steel heat exchanger, ensuring zero water pollution. 7. Compared to indirect heating methods (boiler + external heat exchanger + circulating pump + materials + additional costs), the additional costs are reduced by 30-40%. 8. High efficiency, rapid heating, and excellent heat exchange result in fuel cost savings of over 20-30%.
