Abstract:

A hot-water supply system comprising: a switching valve (35) to which a water supply pipe (P1), an inlet pipe (P3) connecting to a hot-water supply device, and a return pipe (P4) returning from a water softening device (30) are connected and which has a bypass circuit bypassing the water softening device (30) and formed by directly connecting the water supply pipe (P1) and the inlet pipe (P3) connecting to a hot-water supply device; and a control means (50) for switching, by means of the switching valve (35), between a mode for supplying water from the water supply pipe (P1) to the water-softening device (30) and a mode for supplying water from the water supply pipe (P1) to the hot-water supply device (1) through the bypass circuit. The control means (50) is provided with: a switching valve drive circuit for switching, on the basis of the determination of the timing of salt replenishment, the switching valve (35) to the mode for supplying water from the water supply pipe (P1) to the hot-water supply device (1) through the bypass circuit; and a display drive circuit for displaying on the display (51) of a remote controller (RC) that salt replenishment is required.
