250L with 30tubes solar water heater
 
 
           Non-pressure vacuum tube solar water heater depends  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.
