STORAGE TYPE HOT WATER SUPPLY DEVICE

PROBLEM TO BE SOLVED: To provide a storage type hot water supply device having a hot water supply booster pump and a bath booster pump, preventing negative pressure breakage caused by simultaneous use of both pumps, and failure caused by air biting. SOLUTION: This storage type hot water supply device includes the hot water supply booster pump 31 disposed on the way of a hot water supply pipe 29 and supplying hot water/water to a faucet 4 by raising a pressure, and further includes: a bath mixing valve 34 for mixing the hot water from a hot water supply pipe 35 and the water from a second water supply bypass pipe 36; a bath flow sensor 39 disposed on the way of the hot water supply pipe 35, and detecting hot water supply flow from the bath mixing valve 34; and the bath booster pump 41 disposed on the way of the hot water supply pipe 35, and supplying the hot water/water to a bathtub 6 by raising the pressure of the supplied hot water/water. When the hot water supply booster pump 31 and the bath booster pump 41 are simultaneously used, the hot water is supplied with priority, and the driving of the bath booster pump 41 is stopped, thus usability is improved, and the storage type hot water supply device can be used in ease without worrying about trouble in actual use.
