Abstract:
PURPOSE:To provide an automatic hot water supply device capable of eliminating troubles which increase hot water supply time by repeating water injection and minimizing errors between a bath tub water level and a setting water level in terms of an automatic hot water supply device which starts hot water supply based on a hot water supply command and continuously supplies an additional amount of hot water supply after having reached the set value of water level and drives a circulation pump based on a circulation command. CONSTITUTION:When a bath tub water level has not reached a setting water level after having driven a circulation pump, a first setting volume is added to the additional hot water supply volume so as to set the resultant value.
