HOT WATER STORAGE UNIT AND HOT WATER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a hot water storage unit which inhibits movement of a water heat exchanger and prevents damage of the water heat exchanger.SOLUTION: A heat insulation material 16 includes a support part 60 and a lid part 65. The lid part 65 has a facing surface 65c facing an upper surface of a water heat exchanger 12. The facing surface 65c inclines so that its position becomes higher in a direction that the lid part 65 is inserted into an opening part 62 of the support part 60. The lid part 65 contacts with the water heat exchanger 12 on the facing surface 65c and thereby fixes the water heat exchanger 12 with the support part 60.
