Filed: 2001-06-20
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in a hot-water storage-type water heater. SOLUTION: A low-temperature tank T1 and a high-temperature tank T2 are connected in series through a connecting pipe 6. The tank T1 and the tank T2 are provided with hot-water outlets 5 and 9, respectively, and an inlet 3 of the tank T1 is connected with a feed water pipe 1.

The capacity of the tank T2 for a high temperature is set at a smaller value than that of the tank T1 for a low temperature. Since only a portion of the entire storage of hot water is kept at a high temperature, the time required for boiling can be shortened, and the power consumption rate for boiling and reserving heat can be reduced. Further, since the high-temperature hot water is not consumed when using the low-temperature warm water, the high- temperature hot water can be reserved.  When all the high-temperature hot water has been consumed, the warm water in the tank T1 is supplied, and thus the time required for boiling is shortened. The tank T1 may be made of synthetic resin.
