Compact non-pressurized solar water heater
Working Principal
Compact non-pressurized solar water system of all-glass evacuated tubular collector integrated with storage tank, are ideal for use in small units, houses and other applications where cheap, reliable hot water supply is required. Simple, economic and practical.
As we know the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
When cold water in vacuum tubes is heated it become lighter and flows to the water tank while cold water in the tank goes down to the vacuum tubes. With this circulates the cold water in water tank will be hotter and hotter.
Vacuum tube
Achieves the National Standard GB/T 17049-1997
Excellent solar-thermal conversion and low heat loss
Highly reliable, using borosilicate glass 3.3
Long vacuum life time

Insulation layer
With high pressure constant temperature and fixed
quality integrated polyurethane foaming technology,
the insulation efficiency is perfect and durable.
Foaming density: 35g/cm³
Closed-cell foam rate: 95%

Mechanical automatic filler
Optional filler makes your
operation much more easily,
especially convenient for those
where the water pressure is not regular.
Anode magnesium rod
Equipped with anode alloy magnesium
rod to protect the heater and inner tank from corrosion and scaling.
Thermistor
It will shut off the power if the temperature reaches the pre-set point, so as to protect the users from scalding
