Compact Non-pressure solar water heater system

The compact Non-pressure solar water heater relies on the natural circulation of water between the collector and the tank or heat exchanger. As water in the vacuum tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system.Compact Non-pressure Solar Water Heater (SJK series) relies on density of the water, cold water down, hot water up, a cosmical physics. To circulate water through the collectors and the tank. When water in the collectors is heated up, it becomes lighter and naturally rises into the tank. Meanwhile, cooler water in the tank flows down to the collectors.In this type of installation, the tank must be together with the collectors. These systems are reliable and relatively inexpensive but be careful with the installation, because the water tank is much heavier than that you thought.
