Need to make a short circuit. If the solar water heater is not used for a long time at minus 15 degrees, the water supply valve should be closed and the water in the water heater as well as the upper and lower pipes should be drained to avoid prevent the pipes from freezing.
If you normally use a solar water heater, it is best to use water from the water heater in small quantities and several times a day. Especially before going to bed, you can connect a basin of water under the nozzle or faucet, loosen the hot water valve a little and let it drip slowly to maintain the water flow in the heater smooth solar water and effectively avoid freezing and blockage of the pipeline. .
When using, water should be supplied according to weather conditions. If the temperature is low, water should be supplied the next morning to prevent freezing of the pipes leaving the heaterwater. If it rains or snows the next day, you can add half a tank of water, or more than half a tank of water according to actual needs, if the water consumption is large, you can consider starting the solar electric heating device; water heater.
Detailed informationIn winter, you should pay attention to the weather forecast to get a more satisfactory water temperature. If the sun is not strong that day, you can add half a tank of water, or even more than half. a water tank, according to actual needs. If the weather is good the next day, the water tank of the solar water heater can be filled. If the temperature is low, it is better to refill the water tomorrow morning, which will avoid pipes at the solar water outlet. heating of the gel.
Perform a complete inspection. Check for disconnected, leaking, cracked, etc. pipes. and use good quality insulating materialsé or antifreeze devices for protection. If there is a heating tape during installation, the pipe heating tape will automatically heat the pipe according to the outside temperature. When the temperature reaches a certain temperature, the heating tape will automatically cut off the power, which can effectively protect the pipeline and prevent. frozen.
How to maintain solar water heaters in winter if they are not needed?
Antifreeze methods for solar water heaters include the use of antifreeze, draining water pipes and insulation measures.
1. Use antifreeze
In winter, especially in cold regions, the water in the solar water heater may freeze, causing water pipes to break. Using antifreeze can effectively lower the freezing point of water to prevent freezing. Antifreeze is usually a special chemical mixed withthe water. When choosing antifreeze, make sure it is compatible with your solar water heater and follow the manufacturer's instructions for adding it.
2. Drain the water lines
Another way to prevent freezing is to drain the water from the solar water heater. During the coldest periods of winter, the water in the water heater can be drained to prevent freezing. This method requires installing a drain valve on the water line so that it can be easily drained when needed. Of course, the downside to this method is that you have to wait for the water heater to heat up before you can use hot water.
3. Insulation measures
Effective insulation measures for solar water heaters are also key to preventing freezing. For example, wrapping insulation around your water heater's pipes and storage tank can reduce heat loss and prevent water from freezing. EnsureAlso ensure that the seals and vents of your solar water heater are intact to prevent cold air from entering the interior of the water heater.
Recommended daily maintenance of solar water heaters:
1. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then the hot water. water to avoid burns.
2. There is usually a filter device at the outlet of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase the amount of water and smooth. exit.
3. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises. You can alsot use a hair dryer to blow on the water line, or wrap a towel around the water line, then slowly pour it with warm water. Do not cook it on fire, 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.
If the solar water heater is not used in winter, the water must be drained.
If there is no sun in winter, you can use a water heater. You need to drain the water in the sun, close the valve and remove the interior plugs to keep the water out of the top and top. lower water pipes against freezing. Prevents water pipes from freezing and cracking due to low temperature and insufficient water circulation.
If the heaterSolar water heater is filled with water in winter, when the temperature is too low, the water in the pipes can easily freeze, freeze the pipes, or even crack the solar water heater. In sunny weather, you can use the solar water heater normally; When the temperature is below -5°C, it is best to use the water heater several times a day.

Maintenance methods of solar water heaters in winter:
1. When the temperature continues to be below 0℃ in winter, it is necessary to turn on antifreeze devices such as electric heating tapes for preheating protection. Especially in cold northern regions, when the temperature is always below zero, it is necessary to always turn on the heater and antifreeze device.
2. When using solar water heaters in winter, the water filling time should bebe determined according to the degree of cold.
3. If there is no solar water heater installed in tropical areas, etc., if the weather is cold, you can turn on the sprinkler or hot water faucet, place a basin underneath, relax the 'Hot water. outlet valve, and let it go down slowly, in order to maintain the flow of water in the pipes and avoid frostbite in the pipes.
