To clean the solar tubes, we can follow the following steps: first pour the water into the collector tube, and at the same time pour out the scale. Remove one, shake it lightly, and pour it in while it's still hot. Then pour water with a spoon, shake and rinse several times until clean.
Remove the rubber sealing ring inside the water tank mouth. After removing them all, rinse them with water, especially on the inside, to ensure a good seal with the collection tube. Clean the scale from the water tank. Use a curved tool to remove large areas of tartar, then rinse with plenty of water.
Finally install the rubber seal. Use your hands to facilitate installation from the two holes and place it on the stainless steel edge of the water tank. After installing the heat collecting tube, prepare some detergent thinner,Rinse the top of the solar tube with water, apply a little detergent solution and slowly push the top into the water tank. Be careful not to damage the lower vacuum glass nozzle.
After using a solar water heater for a period of time, a large amount of scale will be produced, which is related to water quality. Once scale is generated, thermal efficiency is significantly reduced. The water used to heat up very quickly, but now the water temperature no longer increases because the scale forms an insulating layer between the inner wall of the heating tube and the water. , blocking heat transfer. After using ordinary solar water heater for 3-4 years, the hot water temperature drops significantly, the sensor fails, the electric heating tube ruptures, and the hot water turns yellow and mixes. The reason is due to tartar. Indeed, a small amount of sediment and imPurities in tap water settle inside the vacuum tube and inner tank; the solubility of calcium and magnesium salts in water decreases during heating, forming crystalline precipitates and precipitating water in the solar water heater; heats up slowly and a large number of bacteria reproduce and form dirt with scale. If you want to clean it yourself at home, you need to prepare solar appliance descaler and some common tools needed.
