Vacuum hot water boiler is a kind of hot water boiler with vacuum negative pressure inside. Most of them use gas fuel and oil fuel. Compared with ordinary hot water boiler, vacuum hot water boiler has higher operating efficiency and will be more efficient. Safe, basically no safety risks such as explosion.
The vacuum hot water boiler is already very safe, do I still need to conduct an annual inspection? Let Zhengzhou Fangkuai Boiler Factory answer for you.
According to the "Notice on Implementation of Safety Technical Supervision Regulations for Small and Atmospheric Hot Water Boilers" issued by the General Administration of Quality Supervision, Inspection and Quarantine in 2002, it is mentioned that the vacuum phase change boiler has a pressure lower than atmospheric pressure because of its medium circulation system. Therefore, there will be no explosion accident. Manufacturers should manufacture vacuum phase change boilers according to standards, and bear the legal responsibility of informing users (including boiler installers) of safe use and ensuring that the boiler system is always in a vacuum state during use. The installation unit of the vacuum phase change boiler shall be responsible for the quality of the installation meeting the installation requirements specified by the manufacturer.
After installation, the vacuum phase change boiler that meets the above requirements does not need to be confirmed by the boiler and pressure vessel safety supervision agency of the administrative department of quality and technical supervision, nor does it need to go through the registration procedures for use. Therefore, the vacuum boiler does not need to be confirmed by the administrative department of quality and technical supervision after installation, and there is no need to go through registration procedures.
