<p><P>PROBLEM TO BE SOLVED: To provide a water heater system increasing capacity without using more consistent large additional energy in a point of a water temperature in a used portion with increased capacity of high temperature water, increasing capacity in a state minimizing addition of complexity, and providing additional capacity in a state minimizing additional maintenance demand. <P>SOLUTION: The replenishing water heater tank, and system are characterized by a replenishing tank provided with an inner vessel surrounded by an outer jacket. In a space between the inner vessel and the outer jacket, almost all air is evacuated so that the inner vessel is vacuum insulated. The replenishing tank is provided with a water inlet port and a water outlet port. Water is heated in a water heater, and it is transferred from an upper portion of the water heater tank to a lower portion of the vacuum-insulated replenishing tank through an insulated line and a dip tube extending between a water inlet port and a bottom of the inner vessel. The high temperature water is withdrawn from the upper port 8 on of the inner vessel of the replenishing tank for use in a home or the like. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
