How much does a glass tube for solar water heater cost? Are they universal?
Of course.
Of course you can, but it is better to install a solar panel with electric heating. Use solar power when the sun is shining and use electric heating when there is no sun. Solar panels now have this function. Previously installed solar panels did not have this. Is it easy to use?

Common vacuum tubes on the market have two diameters, 47 mm and 58 mm. Almost all major brands of solar tubes have a diameter of 58mm. Attention should be paid to the length of the vacuum tube. For example, if you use a vacuum tube with a length of 1.6 meters, you can insert a vacuum tube with a length of 1.8 meters. the tube inserted into the water tank is too long, the circulation of water inside the water tank will be restricted, causing the water temperature to be too low, etc. Therefore, when replacing the vacuum tube, the diameter and length should be the same as the original tube size.
