Product Description

solar water heater Work principle: High quality vacuum tubes absorb sunshine and heat cold water in the vacuum tubes. According to the density difference of cold and hot water, when absorbing sunshine, cold water in vacuum tubes turning to hot water rises to tank, meanwhile, cold water in tank sinks to vacuum tubes. That is the circulation in this type of solar water heater. The whole system is always circulating continuously. Specification: 1.
