Summary:To provide a solar water heater capable of heating water in a shorter time than before.SOLUTION: Since a metal outer pipe 15 is provided outside an injection pipe 14 and an air layer A is formed between the injection pipe 14 and an outer pipe 15 with both ends closed by waterproof plugs 16, even when the outer diameter of a heat collection pipe 12 is increased, the capacity of a return flow path B formed between the outer tube 15 and the heat collection pipe 12 does not increase. Therefore, by expanding the diameter of the heat collection pipe 14, increasing its surface area, and absorbing more energy of sunlight L, it is possible to heat water W in a short time.SELECTED DRAWING: Figure 3 【課題】従来よりも短時間で水を加温することができる太陽熱温水器を提供する。【解決手段】注入管１４の外側に金属製の外管１５を設けると共に、注入管１４と外管１５との間に両端が防水栓１６で塞がれた空気層Ａを形成したため、集熱管１２の外径を大きくしても、外管１５と集熱管１２の間に形成される戻り流路Ｂの容量は大きくならない。そのため集熱管１４の径を拡大して、その表面積を増大させ、太陽光Ｌのエネルギーをより多く吸収することにより、水Ｗを短時間で加温することが可能となる。【選択図】図３
