This technology uses phase change materials to store excess heat or unused heat energy generated in the process of heat consumption through phase change energy storage materials, and wait until the heat demand is high and the system is charged during peak electricity consumption, so as to achieve the effect of shifting peaks and filling valleys by transferring energy in time.

[0003] A Chinese patent with publication number CN208794732U discloses a bathroom cabinet with an integrated phase-change energy storage water heater. The cabinet stores a large amount of heat energy through material phase change during the low-power period at night. When hot water is needed, cold water exchanges heat with the phase-change heat storage material to displace the heat stored in the phase-change heat storage material. However, in this solution, the heat generation method is unique, and heating is only performed through the water heater, and a heating working medium circulation cannot be formed, resulting in low heat storage efficiency.
