Abstract
Provided is a hot-water supply device. A process performed by a control device of the hot-water supply device includes: a step of shifting an action mode of the hot-water supply device to an instant hot-water mode; a step of measuring an amount of water X; a step of determining that another tap interruption occurs when the amount of water X is equal to or greater than a basic flow amount Y+α; a step of stopping action of a circulation pump; a step of re-learning the amount of water X when the amount of water X is less than a basic flow amount Y−β; a step of ending the instant hot-water circulation mode when an end condition of the instant hot-water mode is satisfied; and a step of measuring the amount of water X when the end condition of the instant hot-water mode is not satisfied.
