Hot water supply piping constructed according to this device can also be extremely effective in preventing freezing in winter, and compared to conventional hot water supply systems in which a heat storage device is placed near the hot water faucet, it is possible to make effective use of the thermal energy of the hot water stored in the piping, thereby greatly improving energy conservation. Furthermore, by connecting the water heater and the faucet with a circulation pipe,
In comparison with a hot water supply system in which a circulation pump is connected to the return line of the circulation line, the hot water supply pipe of the present invention has extremely little heat radiation loss. In addition, in the present invention, since the heat storage body P is composed of many independent heat storage material storage chambers 6 separated by partition walls 4, even if the heat storage body P is cut when installing the hot water supply pipe 3, the amount of leakage of the latent heat storage material 7 from the heat storage material storage chambers 6 can be kept to a minimum, and good workability can be ensured.
