Design and Performance Testing of a Solar Water Heater

This work combines flow by natural convection and forced flow in the design of a solar water heater. The solar water heater was designed such that the entire process was powered by solar energy. This study is focused on the efficiency of the system and the output temperature obtained in Edo State, Nigeria, at Latitude 6.540N of the equator. Experimental tests were conducted in the mid rainy season, through the month of June 2017. The result showed the maximum heat rise of 110C and a minimum of 60C . However, the results displayed are the average of each week of the month of June 2017. The overall efficiency of the system was found to be 54.54%, indicating that more improvement is required for increased efficiency and optimum heat supply
