Characteristics：The tank for this model is a kind of closed type, the one with normal working pressure- 6bar, so it can be connected with city water directly. It will relief the pressure automatically, when the pressure is more than 6 bar inside the tank. And the water is heated rapidly by heat pipe which will transfer the heat energy into the tank (can refer the page 3 about heat pipe vacuum tube). This model can heat the water much faster than non-pressure and pre-heat models. The pressure of this model will be decided by the pressure of the tap water.
