When the water in the water tank is completely drained, hold each vacuum tube back and forth with both hands, loosen the sealing ring on the vacuum tube and the water tank, and push it into the water tank. When the bottom of the vacuum tube can be removed from the fixed base, pull the vacuum tube out of the water tank; take the water out of the vacuum tube and pour it out, so that the scale is poured out.
The limescale mixes with the water in the vacuum tube and doesn't stick around the vacuum tube like the water bladder of a thermos. Then add some clean water to the vacuum tube and rinse it so that the vacuum tube will be cleaned a few times. Clean each vacuum tube one by one, and check one by one whether the sealing ring on each vacuum tube installation hole of the water tank is in good condition.
If it is damaged, it should be replaced with a new sealing ring to prevent the water in the water tank from leaking from the sealing ring of the vacuum tube. As a new type of energy-saving and environmentally friendly energy, solar water heaters have been chosen by many families. It can not only meet people's needs for hot water in life, but also be a renewable resource.
This economical and environmentally friendly function is the reason why many people choose solar water heaters for solar cleaning. After using the solar water heater for a long time, some problems will be found, the water output becomes smaller and the temperature rises slowly. This time may be because you did not clean the water heater. Here's how to clean your solar water heater.
The thermal conductivity of scale is much lower than that of metal, and the thermal conductivity of metal steel pipe is 6 to 1000 times that of scale; scale on vacuum tubes will seriously affect the temperature of hot water; hard scale will reduce or even make the heat conversion rate of solar energy invalid. This is why the water temperature of the solar water heater decreases and the water supply decreases.
Scale contains a variety of chemical components, and the long-term accumulation of precipitation is the increase of harmful substances in the water, which may cause skin irritation. Mud, microorganisms and bacteria also produce many harmful substances in the long-term continuous renewal and alternating reactions. It can cause a variety of skin diseases. Some women and children sometimes experience itching and erythema after bathing.
