Pre-heated Copper Coil Solar Water Heater

 Materialof inner tank: Stainless steel SUS304Materialof outer tank: Color steelOperational pressure: 6barInletand outlet sizes: 1/2'' or 3/4”Tubecoating: Al-N/Al or SS-ALN-CuStagnation temperature:250 CInsulation: Polyurethanewithout freonMaterialof Stand: Color steelWorkingTemp.: From -40 °C to 100 °C How itworks:1,Connect the copper inlet /outlet with tap water piping directly.Water is feed automatically by the water pressure. The vacuum tubeabsorb the sun energy and transfer the heat to the tank .Then tankwater warm the water of coil in a short time.2, Solarabsorption: solar radiation is absorbed by the vacuum tubes andconverted into heat.3, Solarheat transfer: The tank water conduct the heat from within thesolar tube up to the coil.
