热水器出水不热原因:真空集热管和反光板表面沉积较多灰尘或有遮挡物;真空集热管漏气失掉真空度;热管失效:天气不好,日光辐射能量不足,气温偏低;水阀件关闭不严,处于缓慢上水或泄水状态。解决办法:根据以上原因分别采取以下办法:擦去真空集热管及反光板表面的灰尘,移走遮挡物;更换真空集热管;更换热管;使用电辅助加热装置;拧紧阀门,使其不漏水或检查阀门质量, Water heater water is not hot Cause: the vacuum tube and reflector surface deposition of more dust or shelter; vacuum tube leaks lost vacuum; heat pipe failure: the weather is not good, solar radiation energy is low, the temperature is low; water valve Close lax, in the slow water or discharge status. The solution: According to the above reasons, respectively, take the following measures: Wipe off the vacuum tube and the surface of the reflector dust, remove the cover; Replace the vacuum tube; Replace the heat pipe; Use of electrical auxiliary heating device; Tighten the valve so that it does not leak or Check the valve quality,
