The end cap has one or four screws. Just remove the screws. Pay attention to the living. The end cover is connected with electrical appliances and wires. When prying, first insert the metal plate into the gap between the end cover and the barrel, so that the metal plate forms an acute angle with the barrel. Pull the metal plate along the arc of the barrel and turn it evenly. The operation method is as follows:

First of all, it is best to remove the solar water heater on cloudy days, in the morning or at night, because all the hot water in the solar water heater must be discharged before removal. At this time, if it is noon, strong sunlight will damage the vacuum tube, because the water in the vacuum tube has been exhausted, which will shorten the life.

Second, when disassembling, it is best to lubricate the vacuum tube with water soaked with detergent or washing powder. At the same time, pay attention to the angle of the vacuum tube, avoid cross-angle stretching, and prevent the vacuum tube from bursting and hurting people. After the vacuum tube is disassembled, it is packed with a special foam polyester frame and put into a special carton to prevent bumping during transportation.

3. Unscrew the four roses installed on the bracket, and the solar water tank can be disassembled. Then the bracket can be completely disassembled, and the accessories of the solar water heater only need to disassemble the probe, thermostat and solenoid valve.

Working principle of solar water heater;

Solar water heaters convert solar energy into heat energy and heat water from low temperature to high temperature to meet people's hot water use in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, with vacuum tube solar water heaters as the main one, accounting for 95% of the domestic market share.

Vacuum tube household solar water heater consists of heat collecting tube, water storage tank, bracket and other related accessories. The conversion of solar energy into heat energy mainly depends on the collector tube. The collector tube uses the principle of hot water floating and cold water sinking to make the water produce microcirculation and reach the required hot water.

When the vacuum tube water heater absorbs heat, the solar radiation passes through the outer tube of the vacuum tube, is absorbed by the heat collecting coating, and then is transmitted to the water in the tube along the inner tube wall. After absorbing heat, the temperature of water in the pipe rises, and the specific gravity decreases and rises, forming upward power and forming a thermosyphon system. As the hot water moves upward, it is stored in the upper part of the water storage tank, and the water with lower temperature is continuously replenished along the other side of the pipeline, and finally the whole tank of water rises to a certain temperature.

Flat-panel water heaters are generally split-type water heaters. The medium naturally circulates in the heat collecting plate due to thermosiphon, and the heat irradiated by the sun on the heat collecting plate is transferred to the water tank in time, and the heat in the water tank is transferred to cold water through heat exchange (jacket or coil). The medium can also realize heat transfer through pump circulation.
