The use of Liquefied Petroleum Gas (LPG) as an energy source for cooking in Indonesia is estimated at 63.1 MBOE in 2020. One form of LPG utilization is generally heating air, both conventional and using water heaters. Limited domestic supply requires substitution to other types of energy specifically renewable energy. The intensity of solar radiation reaching the earth at 1367 W/m2 provide great potential for the utilization of solar energy through solar water heater as a source of water heating. The study was conducted with serpentine tube arrangement and using 0.5 liters/minute continuous flow rate which is analyzed by the 2nd law of thermodynamic. This study also aims to analyze the effect of solar intensity to differences temperature of collectors, the amount of exergy gain for heating the water and the effect of solar intensity to exergy destruction. From the research, it was found that the higher solar intensity, the higher the temperature difference between input and output and exergy destruction. The highest efficiency is 3,2%. The low efficiency of collectors is caused by the higher exergy destruction.
