Should the solar water heater be emptied when it is sunny but freezing?

Yes.

In windy weather, make sure the water heater is full of water to prevent the solar water heater from being knocked over or even knocked over. During very cold winters, drain the water heater properly to avoid damage from freezing and expansion of the water heater. In addition, the solar water heater should also be cleaned regularly and the magnesium rods should be replaced regularly to prevent excessive scale from damaging the water heater and pipes and affecting its use.

< p>Notes:

Before winter, carry out a comprehensive inspection of the solar host and pipe connections, and replace the damaged parts in time to avoid cold accidents in winter. Users who do not use solar energy in winter should ensure that the water tank is full of water to prevent tvacuum tube explodes and the rubber ring is damaged by heat and aging due to prolonged air drying.

When the weather is extremely hot and the water temperature is extremely high, it is strictly prohibited to add water immediately after running out of water, because the water supply to this moment can easily cause the pipe to burst. The best time to fill the solar water heater is two hours before sunrise in the morning or two hours after sunset in the evening, to ensure the life of the solar water heater.

People's Daily Online - 99 ℃! High temperature solar water heater “explodes” (photo)

In winter, the temperature is minus ten degrees Celsius. If the solar water heater is not used, water needs. to empty; If the solar water heater is used normally, the water should be drained accordingly.ion of the weather. You can add water appropriately if necessary, and it is best to use water from the water heater in small quantities and several times. every day.

1. In sunny weather, the solar water heater can be used normally. When the temperature is below -6℃, it is best to use water from the water heater in a small amount and several times a day. day. Especially before going to bed and after getting up, put a small amount of water to flow the water into the pipe, and rely on the water temperature to increase the temperature of the pipe. The lower the temperature, the more water must be drained to prevent water pipes from freezing and clogging.

2. If the temperature is below -6℃ the next day, fill the water tank with water after running out of hot water the day before. Loosen the hot water tap a little and let it drip slowly to maintain thewater flow in the pipe. Generally, the flow of one basin of water per night can prevent the pipe from freezing and clogging.

3. If it's cloudy or snowing, try draining the water from the solar water heater and leaving the mixer on so the pipes don't freeze.

4. If it is not used for a long time, the water in the water tank should be drained to avoid freezing damage to the solar water heater.

Energy use and maintenance precautions solar in winter: < /p>< p>1. Pay attention to the weather forecast 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. water reservoir. , 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 islow, it is better to fill the water tank tomorrow morning. It is advantageous to avoid freezing of the pipes at the outlet of the solar water heater.

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 effectively protect the pipeline and prevent. frozen.

3. The exhaust port of the solar water heater water tank should be kept clear if it is blocked, this may cause the water tank to swell or collapse. If the outdoor temperature is too low, it is recommended to stop using the solar water heater and drainall water from the water heater and pipes to prevent freezing and cracking of water pipes due to low temperatures and lack of circulation.
