Introduction of Non-Pressure Solar Water Heater:Non-pressure Solar Heater is one of the most economical solar water heating device with pretty high efficiency at the same time. It consists of hot water storage tank, solar vacuum tubes with mouth plug in storage tank, and bracket supporting tank and tubes.When cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to storage tank and colder water goes downward to glass tubes. through this continuous circulation, the cold water in storage tank will be gradually heated till sunset.ÿSpecialty:1.ÿÿÿ High thermal performance and working temperature: the heat exchanging rate even in winter can up above 55%.2.ÿÿÿ Heat collecting efficiency is at least 20% above common solar systems.3.ÿÿÿ Work in all day and all season: no matter any corner of the world, this system can work well even -40?ÿto avoid the tube freezing problem.4.ÿÿÿ Reliability: No water following through the tube, so water scale can not generate and tube cracks could be avoided, the system still can keep working even with some damaged tubes.5.ÿÿÿ It can connect with water tap and work automatically with pressure0.6Mpa, bring enjoyable washing experience.6.ÿÿÿ Safety: P/T valve would release pressure and temperature to protect tank..ÿÿTechnical Specification:1.ÿÿÿ Outer tank material: SUS304ÿstainless steel or powder coated color steel2.ÿÿÿ Inner tank material:ÿ1.2mmÿthick SUS304 food grade stainless steelÿÿ( Optional material SUS316L)3.ÿÿÿ Vacuum tube material: borosilicate glass 3.3; AL-SS-CU absorb coating, with copper heatÿÿ pipe inside4.ÿÿÿ Frame material: 1.2mm thickness stainless steel5.ÿÿÿ Insulation material: 55mm thickness polyurethane6.ÿÿÿ Suitable for mains pressure water(up to 8 bar/116psi)7.ÿÿÿ Easy plug-in installation8.ÿÿÿ Install the T/P valve on the pressurized tank9.ÿÿÿ Seal material: Stabilized High Temperature SiliconOuter tank material: SUS304ÿstainless steel or powder ÿ ÿ ÿcoated color steelInner tank material:ÿ1.2mmÿthick SUS304 ÿ ÿ ÿfood grade stainless steelÿÿ( ÿ ÿ ÿOptional material SUS316L)Vacuum tube material: borosilicate glass 3.3; AL-SS-CU absorb ÿ ÿ ÿcoating, with copper heatÿÿ pipe insideFrame ÿ ÿ ÿmaterial: 1.2mm thickness stainless steelInsulation ÿ ÿ ÿmaterial: 55mm thickness polyurethaneSuitable for mains pressure water(up to 8 bar/116psi)Easy ÿ ÿ ÿplug-in installationInstall ÿ ÿ ÿthe T/P valve on the pressurized tankSeal material: Stabilized High Temperature Siliconÿ19.
