In this research work, a transient model of solar water heating system integrated with a phase change material (SWHS-PCM) is proposed to study the effect of solar collector area, the mixed capacities of water and PCM and heat exchanger effectiveness of the SWHS-PCM for heating the fish pond during winter. The simulated results showed that the fishpond with SWHS integrated PCM-Type1 can maintain the water temperature between 28 and 30 °C. The optimum parameters to provide the fish pond temperature between 28 and 30 °C are 1.77 m2 of the solar collector area, water and 0.4 and 0.007 m3 of water and PCM-Type1 capacities and 0.5 of the heat exchanger effectiveness. Moreover, it was found that PCM-Type1 heated the fish pond in form of sensible heat. However, with PCM-Type2, the studies revealed that 1.77 m2 of the solar collector area with water and PCM-Type2 capacities of 0.4 and 0.2 m3 and the heat exchanger effectiveness of 0.8 gave the maximum temperature of the pond. It was observed that PCM-Type2 heated the pond in form of latent heat.
