Abstract (en)

A storage-type hot-water supplying system (1) comprising hot-water storage tanks (7A, 7B, 7C) connected in series between a hot-water outlet pipe for high-temperature water (4), extending from a heat source unit (2), and a water supplying pipe for low-temperature water (5), leading to the heat source unit (2); wherein a most-upstream hot-water storage tank (7A) closest to the hot-water outlet pipe (4) serves as a hot-water-supplying hot-water storage tank for high-temperature water, and a most-downstream hot-water storage tank (7C) serves as a water-supplying hot-water storage tank for the heat source unit (2); and a hot-water supplying system (9A) for high-temperature water is connected to the most-upstream tank (7A), and at least one hot-water supplying system (9B, 9C) that allows hot water of different temperatures to be supplied via a mixing valve (10B, 10C) is connected to a top portion of a tank (7B, 7C) at the downstream side thereof.
