An improved theoretical model to predict the thermal performance of a natural-recirculation (thermosiphon-flow)solar water heater system is presented. The model considers the entire system to be broken up into a finite number of sections, each individual section having a uniform mean temperature. By considering an energy balance over each section, finite difference equations were written to enable the mean section temperature to be evaluated. Mass flowrate was evaluated from the temperature distribution of the whole system. Good correlation was obtained between predicted and experimental results during the main part of the day. The effect on thermal performance of height of storage tank with respect to absorber unit was examined.
