How to use solar energy for a long time
4, and then into the water tank, when the water from the water tank to install a vacuum tube after the outflow of the hole, and then one by one to install the vacuum tube to the water tank, cleaning the scale of the work is completed.5, clean solar water heaters in the water tank should be carried out regularly, generally according to the local water quality situation, do not need frequent cleaning.6, usually should pay attention to the use of solar water heaters, water temperature inside the water tank below 75 degrees, is not easy to produce scale, so the summer or spring and autumn, add water according to the weather conditions, if the sun is good, the water in the water tank should be used with, this temperature will decrease with tap water to avoid filling. The generation of the scale. As long as there is water in the water tank, the water at any time can not cause the vacuum tube burst damage, unless the water in the water tank is discharged, for several days without water, the vacuum tube in the water evaporates, the water is not in the daytime when the sun, because the vacuum tube has no water at this time, if the temperature is high, with tap water, tap water and the water temperature is very low, it is easy to cause the vacuum tube burst.
2, when the bottom of the vacuum tube can be removed from the fixed base, then the vacuum tube out of the water tank out;3, take out the vacuum tube in the water drained, the scale is poured out, the scale is mixed with water in the vacuum tube, not like that in the thermos bottle water bile paste around the vacuum tube, and then into the vacuum tube add some clean water, rinse clean, so repeated several times the vacuum tube clean up, one by one to each vacuum tube is clean, check each tank vacuum tube is arranged in the hole of the sealing ring is intact, if damaged, should be replaced with a new sealing ring, to prevent the water in the water tank is leaking from the vacuum tube sealing ring;
The method is very simple, but the operation should be careful, can not use brute force, so as not to cause damage to the vacuum tube. Specific method is:1, when all the water in the water tank is completed, each vacuum tube with both hands to hold back and forth rotation, so that the vacuum tube and the water tank on the loose ring, and then pushed into the tank;
