PURPOSE: A solar water heater is provided to perform the easy heat exchange, thereby maximizing the efficiency of the collector. CONSTITUTION: A solar water heater is composed of a collector(11), a thermal accumulator(12), a recovery tank(13), and an auxiliary tank(14). The collector(11) has an air valve(23) at the end. The thermal accumulator(12) provides a hot water heat exchanged at the collector(11) to the certain place. The recovery tank(13) is connected to the collector(11) via a connecting pipe. The recovery tank(13) is connected with the thermal accumulator(12) via a circulating pipe(17) and a recovery pipe(18). The auxiliary tank(14) is connected to one end of the thermal accumulator(12) to provide a refilling water.
