A latent heat thermal energy storage (LHTES) material stores heat by undergoing phase change isothermally and meets the heating requirements [2, 3]. It is the main form of heat storage due to its high energy storage density compared to sensible heat storage materials [4], [5], [6]. For instance, in the solar water heating systems, PCM stores thermal energy for later
