How to choose a solar water heater storage tank

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.
