Vacuum Hot Water Boiler is safe and energy saving heating equipment. Work under negative pressure condition (vacuum), lowers the boiling point of water, greatly reduce the gas temperature, the boiler work under low temperature and low pressure conditions with high thermal efficiency.
Vacuum structure make oxygen corrosion, scaling small and service life longer. Suitable for hot water supply, heating and industrial hot water heating equipment.
Feature
1、Vacuum operating, Low pressure and low temperature
2、Energy saving, less heat loss
3、Anti scaling and anti-corrosion prolong service life
4、Compact structure, easy installation and use
5、Suitable for automatic control system
