No matter where solar energy is used, there will be scaling problems. Under normal circumstances, tartar should be removed once a year. Otherwise, the temperature of solar energy will be worse from year to year. the quality is poor, do not choose a three-cavity tube (Tube within a tube). There are currently three ways to prevent and eliminate solar scale (1) Add a magnesium rod with scaling function during installation. no effect. Even the magnesium rod itself will be chalky. Installation and there is no difference if it is not installed. (2) Simply add descaling agent. General descaling agents are acidic or alkaline and will corrode the. inner tank of water tank. In addition, the scale in the vacuum tube cannot be removed. After 24 hours, remove the tube and pour out the tartar. (3) Physical descaling method: remove the vacuum tube and dry it. on the groundeil for two days, then install it. Before installing the tube, pour water into the solar panel inside, in order to remove the scale in the water tank. This method will not cause damage to solar energy, will save money and will completely eliminate scale. I highly recommend it.
1. Clean with white vinegar: first drain all the water from the solar water heater, then remove all the vacuum tubes, pour an appropriate amount of white vinegar into the vacuum tubes, and let them soak for about 10 minutes. , then scrub them back and forth with a brush. Just cross the clear water on both sides. But be sure to handle it with care, because the vacuum tube is very fragile; 2. Use professional solar descaler for cleaning: buy special solar descaler, open the water inlet of the solar water heater, add the descaler into the water tank. , and let itsolar power automatic heat cycle for 30 minutes, then the descaling liquid will penetrate all parts of the water heater evenly. Then open the drain outlet and drain the water, then fill it with water and circulate it for two minutes. Once the water is drained, the scale can be completely removed.
