なりエネルギーが大変に無駄になるという問題がある。In this operation, the relief valve 18a on the water supply side is used.
If the heater operates first, the low-temperature hot water is discarded, and the loss of energy by the heater 16a can be reduced. On the other hand, if the hot water supply side relief valve 18b operates first, the high-temperature hot water is discarded. In some cases, the warm water heated by the heater 16a is discarded, and there is a problem that energy is wasted very much.

ある。Further, since each of the hot water can bodies 11a, 11b, etc. is fixed to the foundation by three support legs 13a ..., 13aa ..., the fixing operation can be performed relatively easily. Since the number of water supply pipes, connecting pipes or wirings of the bodies 11a, 11b, etc. is larger than that of one hot water can body, it is very troublesome to perform these in the gaps between the support legs 13a ... and 13aa ... There is a problem that accompanies.

, 16b at the same time, and each hot water can 11a, 11b
When the stored water is heated at the same time, since all the stored water in the hot water can 11a on the water supply side is water as shown in FIG. 7, the boiling temperature rises over a relatively long time in accordance with the gradual temperature rise characteristic Ta. go.

出する。The hot water can 11a on the water supply side and the hot water can 1 on the hot water supply side correspond to the rise in the water storage temperature due to the boiling.
The 1b reservoir expands. When the internal pressure of one of the hot water cans 11a and 11b becomes 0.95 kgf / cm2 or more due to the expansion, the relief valve 31a on the water supply side operates. By this operation, the expansion water or the like of the hot water can 11a or the hot water can 11b is supplied to the branch drain 32a, the water distribution pipe 33a, or the water supply pipe 2.
7. Discharge from the connecting pipe 26, the branch drain pipe 32a, and the water distribution pipe 33.

して排出する。When the water in the hot water can 11b is further boiled and expanded, the set pressure is low and the low-temperature expansion water at the lower part of the hot water can 11b is fed to the relief valve 31a which operates before the relief valve 31b. Then, the water is transferred to the hot water can 11a via the connecting pipe 26 and discharged through the branch water pipe 32a and the water pipe 33.
