<p>PURPOSE:To enable hot water having such a temperature as one corresponding to an object of use and hot water such as additional hot water to be got in a low cost and within a short period of time by a method wherein the second hot water discharg ing port is located between a lower heater and an upper heater and disposed in a tank. CONSTITUTION:A cold water supplying port 12 is disposed at a bottom part of a tank and a hot water discharging port 13 is disposed at a top part of the tank. Heaters 14 and 15 are built in a tank 11. This electrical hot water heater has a hot water discharging port 16 in addition to the hot water discharging port 13. This hot water discharging port 16 is positioned between the lower heater 14 and the upper heater 15, for example, located just below the upper heater 15 and further disposed at a circumferential wall of the tank 11, the cold water supplying port 12 is connected to a water source by a pipe, the hot water discharging port 13 is connected to a water plug 19 placed at a bath room, for example, by a pipe 17, the hot water discharg ing port 16 is connected to a water plug 20 installed at a kitchen or a toilet room by a pipe 18. As the water plug 20 is opened, hot water of 35 to 55 deg.C below the heater 15 is discharged through the hot water discharging port 16. As the water plug 19 is opened, hot water of 85 deg.C over the heater 15 is discharged out of the hot water discharging port 13.</p> |
