200L Pre-Heated Solar Water Heater

High pressure solar geyser with copper coil heat exchangerThe main working principle adopts heat exchanging technology.1. Cold water inside the vacuum tube heated by sunshine, and then hot water go up to tank, cold water in tank flow into collector, cold and hot water form a natural circulation in solar water heater, the whole tank water will be hot water gradually.2. Then hot water inside water tank transfer heat to water inside copper coil, people use hot water directly from copper coil.  Specialty:1. Hot water inside copper coil is fresh without secondary pollution; it can be used as portable water2. Copper coil inside tank can take pressure and connect tap water directly.3. Working principle is more advanced than thermosyphon solar water heater.4. Economical type in compact pressure systems.5. Simple structure and easy installation.6. Stable operation and quality. Technical specification:Outer tank material: SUS304-2B /316L stainless steel or powder coated color steelInner tank material: 0.5mm thick SUS304/316L food grade stainless steelHigh purity copper for the heat exchanger coilFrame material: 1.2mm thickness stainless steel or galvanized steelInsulation material: 55mm thickness polyurethaneReliable, efficient, twin-glass Al-SS-CU solar vacuum tubesDesigned to accept mains pressure cold waterCopper coil heat exchanger can be used as part of a closed or open loop system, providing heating to a main hot water tankEasy plug-in installationProduction flow:Packing details:solar water tank 1 carton, stand frame 1 carton, solar vaccum tubes , 10pcs / carton . For sample order, MOQ less than 2pcs , packed by wooden box . Customer installations :For any inquiry, please feel free to contact us !  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
