The vacuum phase change boiler is an eco-friendly hot water heating unit. Its boiler body is open to the atmosphere, maintaining zero gauge pressure at the water level throughout operation.
Model codes for atmospheric hot water boilers are composed of three sections separated by hyphens. Yongxin Boiler is a national Class B boiler manufacturer and a reliable supplier of hot water boilers.
- Operating under negative pressure, the vacuum boiler is explosion-proof and is classified as an inspection-exempt product in my country.
- It utilizes a corrugated furnace liner structure, which increases the heat transfer area while allowing for free thermal expansion.
- The overall design is scientific, rational, and compact, saving 50–70% of floor space.
- It features a built-in stainless steel heat exchanger, ensuring no contamination of the water supply.
- High efficiency, rapid heat supply, and excellent heat exchange performance result in fuel cost savings of over 20–30%.
- The successful separation of high-temperature and high-pressure zones within the boiler’s structural steel components extends its service life.
- Fully automatic control enables intelligent, unattended operation or remote network-based control.
- The heating system configuration (boiler + external heat exchanger + circulating pump + materials + installation) reduces installation costs by over 30–40%.
- Heat exchange occurs within the boiler body itself, achieving an overall system efficiency of over 98%, which significantly shortens the preheating period and minimizes energy waste.
