Abstract: The target of this work is to examine the performance of an integrated solar water heater with corrugated absorber surface. An integrated solar water heater was built and experimentally tested outside so as to observe the temperature variation of water in the storage tank. The present solar water heater capacity is 140 L. Two cases have been studied, which are with and without flow rate. In case of without flow rate, the maximum value of stored water temperature obtained is 58 °C and 78 °C during winter and spring seasons, respectively. The stored water temperature got in the present work is higher than for the previous work principally attributable to the corrugated absorber of the storage tank. In case of with load, the daily thermal efficiency values of the solar collector were 59%, 65%, and 67%, when the mass flow rate values were 0.005 kg/s, 0.0091 kg/s, and 0.013 kg/s, respectively. The outcomes demonstrate that a large thermal losses from the system was observed during the night hours. In addition, the present integrated solar water heater is success to provide hot water suitable to use by the human during the winter and spring seasons of Iraq.
