How to clean the solar tube
Cleaning steps are as followsFirst, open the solar water heater inlet;The second step, then put 1 bottles of detergent (300 grams) added to the storage tank;The third step, automatic thermal cycle 20-30 minutes, so that the full access to all parts of detergent solution;The fourth step, open the drain, drain cleaning fluid;The fifth step, the tank filled with water after recycling for two minutes;The sixth step is to clean the circulating water.
When the water is heated, calcium, magnesium salts, solubility decreased, the formation of crystalline precipitate precipitation; solar water heater in the water slowly hot, bacteria multiply, after the death of sediment, and scale together to form dirt. If you do it yourself at home cleaning, home appliances need to prepare solar detergents and some necessary tools, so you can quickly and thoroughly clean the scale, solar water heater and vacuum tube wall.
After the scale of the thermal efficiency greatly reduced, the original hot water quickly, and now the water temperature is not on the whole, because the scale in the heat pipe wall and water to form a heat insulation layer, blocking the heat transfer. Ordinary solar water heater, with 3-4 years later, the hot water temperature decreased significantly, the sensor failure, electric tube burst, hot water yellowing, mixing phenomenon, the reason is the scale caused by. This is because of the small amount of sediment and impurities in the tap water
First understand the formation of the solar water heater dirt, solar water heater re-use after a period of time, will produce a lot of scale, which is related to water quality.
