HOT solar heater

Solar heater 1. Working Principle: Compact Non-pressure Solar Water Heater relies on desity of the water, cold water down, hot water up, a cosmical physics, to circulat water through the collector and the tank. When water in the collectors is heated up, it becomes lighter and naturally rises into tank. Meanwhile, cooler water in the tank flows down to the collectors. 2.Specification: Material of inner water tank: 0.31mm,/ o.4mm/ 0.5mm / 0.6mm, 304-2B(food-level stainless steel) Material of outer water tank: 0.31mm, 0.4mm, 0.5mm stainless steel,or colorful armor plate, or PVDF Heat preservation: 55mm,60mm imported PU Vacuum tube: single target vacuum tube, coating: AL/N/AL, or Three-target vacuum tube,coating:ALN/ALN-SS/CU Bracket: 1.2mm/ 1.5mm thickness stainless steel or galvanized steel plate or alumminum alloy.
