Compact Non pressurized Solar Water Heater
Features:
This type is a compact non-pressurized system. The design of this type uses the all-glass evacuated solar collector tubes as the heat absorb element. There is a natural circulation system that works on a light absorption principle. Depending on the different density between hot water and cold water, a water flowing cycle is created in the tubes. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from this natural circulation.
