The water in the water heater is frozen and cannot be connected for heating.
Usually, the order in which solar water heaters freeze is: water pipes, collector pipes and water tanks. In the first two cases of freezing, since the location is lower than the electric heater, the effect of using electric heater to thaw is very small, especially when the water pipe freezes, the temperature of the tank d The water is no longer high.
Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion ofsolar energy in thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.

Remarks
1. The water tank of the Gree air heater is placed indoors or on the balcony. A standard floor drain should be preset. near the water tank to keep it normally open and install water isolation facilities around the water tank;
2. If the water pressure in your house is ≥ 2 kg, please install a pressure reducer
3. Tap water pressure in your area. There are many impurities and a filtration system must be installed.
4. Preset hot water lines require insulation.on, especially hot water systems with return lines. Well-insulated ducts will save you a lot of money on energy.
What to do if solar freezes?
The method to prevent water from freezing on the solar panel is: directly open the electric heating tape to defrost the solar panel.
If your home's solar is frozen, you should not use hot water to melt it directly. This will cause uneven heating of the glass tube and make it fragile. Cover the solar panel with a plastic sheet and place it in direct sunlight. After 30 minutes, pour warm water from top to bottom and wait 30 minutes. Remove the plastic sheet, dry the glass tube and place it in the sun.
Many solar systems are equipped with electric heating tapes. If so, the gel will slowly melt after turning on tension for a few minutes. Note that solar water must be refilled in winter, otherwise it will increase the risk of freezing.
Detailed information
The description of solar defrost is as follows:
When the temperature is below zero, turn on the anti-freezing device to freeze the solar water heater Preheat without worrying about power consumption. Especially in cold northern regions, when the temperature is always below zero, the heater and antifreeze device will sometimes be activated. In other areas, antifreeze equipment may be turned on at night if the temperature is low at night.
When taking a bath, be sure to unplug the plug and cut off the power supply to avoid loss of thermal balance. Pipe Freezing Treatment: It is very common for pipes to freeze during the winter. If it turns out that the piasphalt peline has frozen but not cracked, it can be automatically dredged once the temperature is raised. You can also use a hairdryer.
1. Defrost naturally.
When the temperature is high and the sun is shining, let it melt naturally.
For solar water heaters that have been frozen, do not forcibly flush the solar vacuum tubes with hot water. Try not to rinse naturally at the peak of the sun. the solar tube with hot water, otherwise it will damage the vacuum tube.
2. Use electric heating tape to heat.
Each solar hot water pipe is equipped with a heating tape, and when the heating tape is turned on, the solar energy can thaw.

Energy use and maintenance precautions solar in winter: < /p>< p>1. Pay attention to the warningsweather conditions in winter to get a more satisfactory water temperature if the sunlight is not strong that day, you can add half a tank of water, or more than half a tank of water. , 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.
2. Perform a complete inspection. Check for disconnected, leaking, cracked, etc. pipes. and use good quality insulation materials or anti-freeze 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 protecteffectively manage the pipeline and prevent. frozen.
