The quality of Jingpu Solar can be used with confidence. The support is made of cold rolled steel, the same as the highway guardrail! The inner tank is made of food grade stainless steel that meets international standards, and the insulation layer is 55-60mm. The temperature error is guaranteed to be around 5 degrees every day! Vacuum tubes include national standard tubes, and three-tube tubes also have the most advanced "polar tubes" on the market!
The quality of Jingpu Hot Water King solar water heater series is not bad. I just bought one after hearing from a friend. The price listed here is around 1400. Nowadays there are very few at 47 tubes. . I suggest you buy one. Those with 58 branches and those with 58-16 are only 2,200, and can also benefit from a 13% subsidy.
