COMPACT ohne Druck Solarwarmwasserbereiter

Characteristic:1). Material of inner tank: SUS304-2B stainless steel with 0.31mm or 0.41mm thickness. 2) Material of outer tank: 202stainless steel with 0.31mm thickness 3) .Frame: 201 stainless steel with 1.2mm 4)With freeder tank .it can ascend water atomactilly. 4) Insulation: 50mm polyurethane 5)Vacuum tube: 58mm*1800mm 47mm*1500mm Features: Compact non- pressured solar water heater system is a kind of solar water heating systems that solar collector and water tank are connected together with the cylinder storage on the top and collector on the bottom .There is no need of pump to push the fluid and no need of pipeline between the collector and water tank. It is a sample and safe solution to get heat power from the sun. The principle of the system Compact solar water heater relies on density of the water , cold water down, hot water up . To circulate through the collector and water tank. When water in the collector is heated up, it becomes lighter and naturally rises into the water tank. Meanwhile, cooler water in the tank flows down to the collectors
