I'm sure it's not the same company
Tsinghua Sunshine has big advertising efforts, high commissions for sales staff, and agent profits are also relatively large (from after what others have said), so the retail prices are ridiculously high, even higher than the previous ones. Huang Ming understands that they also have cheap ones, but the vacuum tubes are either small or short. I think the quality of Tsinghua Little Doctor's is quite good and the water temperature is good. quite high, reaching over 90 degrees in two days. The insulation is also good and the temperature did not drop overnight.
When I bought, I also weighed between these two brands, and finally chose Tsinghua Junior Doctor, an 18-year-old senior manager, 2,200 yuan, cheap
Certainly! Don't buy it! Otherwise, in case of problem, the after-sales costs will be almost lare the same as the purchase price!
At present, under the condition of ensuring quality, the price in the external market is generally between 110-180 yuan/tube. Because the dealers are different, the prices are also recommended. refer to several companies. Personally, I think it is better to buy For solar water heaters, it is recommended to look at the vacuum tube type, bracket thickness, water tank material and sturdiness of the buyer! Particular attention should be paid to the solidity of the buyer, as this implies after-sales service. Currently, the maintenance rate of single-warehouse solar power is still relatively high, while that of three-warehouse solar power has dropped a lot!
