Advantages of Four-cavity Evacuated Glass Tube
The spring holder does not touch the outer tube and the heat transmission through the spring holder is cut off. Its workability is upgraded by 30-35%.
Water temperature rises much faster. As there is an Interior tube inside, the water in the Four-cavity EGT is 1/5-1/4 less than that in the normal EGT and can be heated up faster. So there is a faster exchange of the cold water and the hot water, producing more hot water.
The neck of the EGT is narrowed at the open end. Tubes in the manifold are closer to each other. More solar energy is absorbed.
