ABSTRACT

A Built-in-Storage Solar Water Heater of 4.5 × 10^-3 m³ liter was designed, constructed and tested for its efficiency. It was observed that the highest temperature of the water obtained is 48^oC. This temperature was achieved between the hours of 16.00 and 16.30 hours local time. The efficiency of the kettle was found to be 1.65%, which is very small due to the construction size. When compared with previous work, the solar water heater that produces up to efficiency of 30% has surface area of 2.6m² while in this work surface area is 0.15m².Keywords: Temperature, Heater, Solar radiation, Efficiency, Absorber plate
