The vacuum boiler is a vacuum environment with negative pressure formed inside the closed furnace body, and the heat medium water is filled in the body. The heat medium water is heated by combustion or other means, and then the heat medium water evaporates - condenses to the heat exchanger, and then the heat exchanger heats the water that needs to be heated. It has the advantages of reasonable structure, safe and reliable operation, high efficiency and energy saving, no explosion risk, no scaling, no corrosion, long service life, multi-purpose, easy installation and maintenance, beautiful appearance and so on. The system operates safely under negative pressure, and is suitable for hotels, restaurants, schools, enterprises and institutions, residential buildings, etc. It can provide heating and domestic hot water at the same time.
1. Safe and reliable operation.
The vacuum water heater always operates under negative pressure and has multiple protection functions. With normal pressure and pressure boiler incomparable safety and reliability;
2, start fast.
Due to the negative pressure, the hot water is generated quickly, and the full load can be reached in a short time;
3, a multi-purpose machine.
Through the configuration of multi-channel heat exchanger, multi-channel heating can be realized at the same time.
4. Save space.
Small appearance, small footprint, low investment costs;
