こませて成形している。In order to reduce the loss of stored heat, for example, as shown in FIG. 3, it is common to provide a unit panel 5 with a heat insulating layer 15 and a cover 16. Normally, the heat insulating layer 15 and the cover 16 are attached in a factory in the state of the unit panel 5 and only assembled at the installation site, and workability is good. In order to facilitate the assembly, the heat insulating layer 15 is thinned or the cover 16 is dented in the vicinity of the joining edge 7 for fastening the bolt 10.

りして、断熱効果が小さいという課題がある。By the way, such a conventional panel-assembled heat storage tank has good workability, but the place where the bolts and nuts are fastened is made by thinning the heat insulating layer 15 or attaching the cover 16 to the cover. There is a problem that heat is radiated from that portion or dew is formed during storage of cold water due to the compaction, so that the heat insulating effect is small.
