There may still be water in the pipe and the dynamic temperature is too low. The water freezes easily and the water pipe bursts. In winter, it is better to drain water from solar water heaters that are not in use, because in freezing weather, if the winter temperature is lower than ℃, the flat panel system needs to drain water from the circulation system ; simply start the antifreeze system without draining the water from the system.
Detailed information:
To clean the exterior of the gas water heater, simply wipe it with a damp towel frequently. Be careful not to use a series of cleaning agents such as acids and alkalis to wipe the water heater;
The burner part of the gas water heater should regularly remove carbon deposits and eliminate them. Put the parts covered with carbon depositsne in a cleaning solution containing carbon remover, soak them until the carbon deposits soften, then wipe them with a brush or cloth. old cloth, then rinse them with hot water and let them dry;
Carbon remover cannot be used to clean carbon deposits on the heat exchanger in order to avoid damage the heat absorption and heat reflection coating layer on the heat exchanger. Simply wipe the heat exchanger with a cloth;
It is necessary to check the power supply frequently. Check if the air line (rubber hose) is in good condition and if there are signs of aging. , cracks, leaks, etc. If undesirable phenomena are observed, they must be treated quickly.
1. Reason 1: There is no water in the water tank. When the solar vacuum tube is exposed to sunlight, the temperature at iThe interior of the tube can reach around 2500°C. it's easy to explode. In winter, the pipes are exposed to the outside. When the weather is very cold, the inside of the pipes freezes and the water cannot be filled. To solve this problem, simply wrap a thick layer of sponge over the water tank pipe. or solar pipe, which can effectively prevent water from not flowing and draining the pipe and bursting the pipe.
2. Reason 2: The temperature difference between day and night is large. During the day, the solar water heater is more likely to explode when water is supplied to the solar water heater. The tube alternates between hot and cold, and there is significant local pressure, which can cause the tube to burst.
In short, whether it is an electric heating tube for solar water heater or an electric heating tube for other liquids, it should not be separated from the liquid and burneddry, otherwise the internal temperature of the liquid will be changed. The electric heating tube will be too high and the electric heating tube will burn out, causing safety hazards.

Daily maintenance
1. When using a solar water heater, there may be a smell of dust or oil in the water pipe. When using it for the first time, you can first open the faucet to remove debris.
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get more heathigh. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high when using a solar water heater. Please turn on the cold water first, then hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth the flow.
6. In winter, it is very common for pipes to be frozen. If the pipe is found to have frozen but not yet cracked, it can usually be cleared automatically after the temperature rises. You can also use a hair dryer to blow on the water line, or wrap a towel around the water line and then slowly pour warm water over it. Do not cook itu fire, do not hit the water pipe or scald it with boiling water, because. this will cause the pipe to burst. Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
