摘要

PURPOSE: A device for automatically controlling water level and discharging hot water for a hot-water tank is provided to improve thermal efficiency by automatically controlling the position of an inlet in a hot-water discharge extension pipe according to water level. CONSTITUTION: In a hot-water tank, a hot-water discharge extension pipe(6a) is connected to the inner end of a hot-water discharge pipe(6). An automatic control unit(100) controls the position of an inlet in the hot-water discharge extension pipe according to water level.
