How to choose a solar water heater storage tank Http:// 1 . Water tank capacity. Some unscrupulous manufacturers have made an article on reducing the cost and the capacity of the internal water tank. The standard ratio of the water tank is: @47mm , length 1 . 2m vacuum tube each ≥5 . 5kg ; 4 47mm , length 1 . 5m vacuum tube each ≥7ks ; &58mm , length 1 . The 8m vacuum tube is ≥10k8 each . For example, a noisy 47nma , 1 . The storage capacity of 5m~18 vacuum tube solar water heaters should be 18X 7ks / support ≥ 126ks , but some products are only about 95kR , the capacity is greatly reduced, the cost is only 180 ~ 300 yuan for the water tank. . Consumers should know the size of the tank and calculate it according to the relevant mathematical formula. 2 . Grade and thickness. The selection of the tank of the solar water heater tank is very important. In order to extend the service life of the tank and protect the health of consumers, materials that are non-toxic, odorless and can ensure clean water should be used. The quality products should be SUS304-2B food grade. Stainless steel, thickness should be 0 . 5mm , the thickness of the pressure type should be 1 . 0mm or more. At present, the top ten well-known Dayangeng water heater brands in China can meet this requirement, while the inferior products use 0 . 3 ~ o . 4mm thickness of stainless steel plate, the cost is greatly reduced, and some manufacturers simply use other grades of stainless steel plate to make the liner ( containing toxic substances and radioactive elements ) , which will directly affect the user's health.

Characteristics and Advantages
(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;
(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.
(3) Anti-clamping function: automatically reverse when meeting barriers;
(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)
(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;
(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;
(7) Bi-doors inter-locking: one of the door leaves always remains closing;
(8)Safety sensor terminal: sensor stops working when door closed;
(9)Unique coating technology: never rusty;
(10)Easy and convenient to install;
(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:
(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;
(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;
(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.
(4)Feet sensor switch applied to avoid contagion;
