Abstract: Provided is a hot-water supply device which stabilizes hot-water supply even at low water pressure. A process performed by a hot-water supply device includes: a step (S510) of detecting that hot-water supply performed by the hot-water supply device is stopped; a step (S520) of reading a set temperature of the hot-water supply from a memory; a step (S530) of calculating a target opening degree of a total water amount servo based on the read set temperature; a step (S540) of sending, to the total water amount servo, a command for setting an opening degree of a passage through which water flows from the total water amount servo into a heat exchanger to the target opening degree; and a step (S550) in which a stepping motor of the total water amount servo moves in response to the command.

Abstract: A hot water supply device includes: a first pipe connected to a water inlet; a flow detector detecting a flow of water in the first pipe; a heating mechanism heating the water; a second pipe through which warm water flows, connected to the first pipe via a third pipe; a circulating pump disposed in a path of the first pipe, sending the warm water in the third pipe toward the heating mechanism during operation; and a control device. Based on acceptance of an execution command of an instant hot water circulation mode, the control device operates the circulating pump, and, in response to a set hot water output temperature exceeding a limit temperature, adjusts a heating temperature of the heating mechanism, so that the temperature of the warm water becomes equal to or lower than the limit temperature.
