The electric vacuum hot water boiler, is a heat exchange equipment that converts electrical energy into thermal energy. It relies on the boiling evaporation and condensation heat exchange of the heat medium to transfer heat, thereby heating the feed water. The micro-pressure phase-change boiler operates under micro-pressure and can supply hot water above 80°C for users with such requirements. The product is characterized by no pollution, no noise, small floor space, convenient installation and use, full automation, safety and reliability, and a thermal efficiency of up to over 98%, making it a green environmental protection product.
