The TRNSYS program is implemented to simulate a thermosyphon solar water heater (SWH). The effect of the volume of the hot water storage tank and the configuration on efficiency is investigated in this paper. The efficiency of the system can be improved by employing larger storage tanks. Similar efficiencies and useful solar heat are given by horizontal and vertical storage tanks. The performance of the SWH is better described by the supplied heat to the load rather than the gained useful solar energy.
