1. Vacuum tubes heat water and storage the hot water in the tank. But we don't use water from tank directly. The tank is just works as a warmer for the copper coil.

 2.You can connect your tap water with the cold water inlet of the copper coil. And outlet is pressurized hot water. The pressure is same as your tap water.

3.You should close the drain openings, if there is dirty or scale inside the tank for a long time, you should open the drainage and clean the tanks.

 4.Please also make sure the vent open, otherwise it will damage tank sometimes later.
