The Vacuum Hot Water Boiler utilizes a closed vacuum environment created through pre-vacuuming and filling with heat medium water. By heating this medium, the boiler generates negative pressure steam. The heat released during the condensation of this steam effectively heats cold water within the heat exchange tube, providing a continuous and efficient hot water supply.
