The paper deals with the study of thermal properties of materials used for heat storage based on phase change (PCM). Specifically, the study focuses on the PlusICE A118 product of the PCM Products Ltd. company, whose phase change temperature is about 118 °C and whose specific heat reaches the value of 2.70 kJ.K–1kg–1. Thermal properties of the PlusICE A118 product in both solid and liquid phase were investigated for this purpose in terms of potential applications. Temperature dependences of its thermal parameters (thermal diffusivity, thermal conductivity, and specific heat) were determined using a transient (step-wise) method. A fractal model of heat transport was used for determination of the above thermal parameters. This model is independent of geometry and type of sample heating. Moreover, it also considers heat losses. The experiment confirmed the formerly declared value of phase change temperature, about 120 °C.
