This article includes a practical assessment of a novel design of the domestic solar collector and verification of its home uses, where the proposed model can be utilized as a water tank instead of the usual cubic and cylindrical tanks utilized in homes. This design is inspired by cutting the cylinder with two levels: a first level is a vertical plane and the second level is inclined with 45°. The experiments were conducted in two locations, the first in the Iraqi Kirkuk city (35.47 N o , 44.39 o E), and the other in the Turkish van city (38°.5 N o , 43.33 o E). Two identical practical models were built for this purpose. The results of the article confirmed the average water temperature of the model under Iraqi weather conditions is higher than the water temperature of the collector in Turkish weather conditions. The results of the model under Iraqi weather conditions showed that the average water temperature reached about 53 °C at 5 p.m. Under load condition, the highest water temperature leaving the new collector was 47 o C at 4 p.m. in Kirkuk. The results confirmed that the average water temperature leaving the collector depends on the volume flow rate of water and the surrounding climatic conditions.
