    vacuum tube solar water hater

    1.Water outlet    2.Air vent   3.Over flow vent   4.Water inlet   5.Sensor hole    3.Over flow vent

    Feature:

    1.Glass vacuum tube solar collector, high temperature,antifreeze,vacuum insulation.2.Food-grade stainless-steel SUS304 2B inner tank,full-automatic welding technology,under 

    the protection of magnesium rod,it can increase of service life.

    3.High pressure polyurethane foaming insulation,as the prefect density and 

    the thermal conductivity coefficient is small, so it can provide effective heat preservation 

    4.The outer tank adopt color steel plate,and it has good double anti-corrosion function.
