Automatic water supply: No need for human supervision. After the controller is set, it will automatically fill the water according to time or water level, and it will automatically stop when the water is full, which is more convenient to use.
Disadvantages: The reason why water is automatically supplied is because a sensor, commonly known as a probe, is installed in the solar water tank, which can sense the temperature and level of the water. This probe has been in a high-temperature water tank for a long time. After a long time, it will be coated with a layer of scale, thus losing the sensitivity to sense temperature and water level. Therefore, the disadvantage of automatic water filling is that there are certain after-sales hidden dangers.
Manual water filling is beneficial: The disadvantage of automatic water filling is the advantage of manual water filling. There is no need to worry about after-sales problems.
Disadvantages: Contrary to the automatic water filling, you need to take care of it when the water is filling. When the water is full, you need to manually close the valve. There is another one. If you install it manually, you need to install an overflow pipe indoors. If water comes out of the overflow pipe when filling the water, it means that the water tank is full of water. To a certain extent, it is also a waste of water resources.
