The solar water heater is efficient, and there is a large merit in energy saving. However, installation expense of the solar water heater is expensive, and the solar water heaters do not spread very much. Ability for collection of heater enlarges the solar water heater by installing a cheap light reflector. In this study, the enhancement of insolation on the collector by the reflector was predicted by simulation. The insolation was maximized at the aspect ratio was 4, the area ratio was 4, the collector angle was 65 degree and the reflector angle was 20 degree. The insolation at the maximum condition was 1.45 times of that at the optimum without the reflector. In addition, the annual fuel saving was 1.37 times in comparison with that without the reflector.
