The first solar water heaters were heated entirely by solar energy. In order to solve the problem of low water temperature caused by cloudy or winter seasons, weather conditions and other reasons, many solar water heaters have added the assistance of electric heating. the basis of solar heating. The heating function can be used when the water temperature is low, and the electric heating is to compensate for the low water temperature.

How to heat a solar water heater without sun?
With the continuous improvement of environmental awareness, more and more families begin to use solar water heaters. The solar water heater is a device that uses solar energy to heat water. It is not only environmentally friendly and energy efficient, but also pgot expensive to use. However, in rainy weather, the performance of solar water heaters will be affected. So we need a solution to solve this problem. At present, electric heating of solar water heater becomes a good choice.
1. The principle of electric heating of solar water heater
The principle of electric heating of solar water heater is very simple, that is, adding an electric heating tube to the water tank 'water. of solar water heater when solar energy is insufficient, it can be heated by electric heating tubes to heat water. In this way, the hot water supply can be guaranteed in rainy weather.
2. Solar water heater electric heating operation steps
1. Buy electric heating tubes
First of all, you need to buy electric heating tubes. There are many types of electric heating tubes. ChChoose the appropriate electric heating tube according to the model and specifications of the solar water heater.
2. Install the electric heating pipe
Install the electric heating pipe into the water tank of the solar water heater. For specific installation methods, please refer to the installation instructions of the electric heating tube or ask a professional to install it.
3. Connect the power supply
Connect the electric heating tube to the power supply. It should be noted that the voltage of the power supply and the rated voltage of the electric heating tube should be the same, otherwise the service life of the electric heating tube will be affected.
4. Use solar water heater for electric heating
In rainy days, you can heat the water in the water tank by turning on the power to ensure hot water supply.
3. Advantagees of electric heating with solar water heaters
1. Improve hot water use efficiency
In rainy weather, the solar water use effect radiators will be affected and through the heating of electric heating pipes, the The hot water supply can be guaranteed and the efficiency of hot water use can be improved.
2. Save energy
Solar water heater is an energy saving device, and the use of electric heating tubes is also very environmentally friendly because its energy consumption is relatively low and its use cost is relatively low.
3. Convenient and practical
The electric heating of solar water heaters is very convenient to install and use. You just need to buy an electric heating tube, install it in the water tank. of the solar water heater and connect it to the power supplyCan.
IV. Precautions for electric heating of solar water heaters
1 Choose the appropriate electric heating tube
When purchasing electric heating tubes, you should select the appropriate electric heating tube depending on the model and specifications of the solar water heater, otherwise the use effect will be affected.
2. Pay attention to safety when connecting the power supply
When connecting the power supply, pay attention to safety to avoid electric shock accidents.
3. You should pay attention to energy saving when using it
Although the power consumption of electric heating tubes is relatively low, you should still pay attention to energy saving when using it. to avoid wasting energy.
How to use electric heating for solar water heaters when it is notthere is no sun.
Without sunlight, solar water heaters are generally heated with electricity. Heating time depends on the capacity of the water tank and the water level in the water tank.
Generally, when the weather is bad, do not fill the water tank, just fill it halfway. This way the heating time will be faster. The water temperature is around 60 degrees. The temperature at which people take a bath is 41 to 45 degrees. If the water tank is full, it will take approximately 3 hours to heat it. If it is half a tank of water, it will take 1 hour to heat it.
The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet the use of hot water by people in life and production.
Solar water heaters are divided into solar water heatersres to vacuum tube and flat solar water heaters depending 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 of solar energy into 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.
Solar water heaters cannot be heated electrically. Working principle of solar water heater: In the hot water system, the fins inside the flat collector convert the absorbed solar radiation into thermal energy, causing the temperature to rise continuously.rature of the working fluid in the heat exchange tube of the collector. Advantage of the low density of hydrothermal liquid, the cold liquid has the characteristics of high density;
Through the circulation pipeline, a natural circulation of cold water up and down and hot water from bottom to top is formed between the collector and the water tank. Thanks to this cycle, the water in the water tank gradually heats up. Since the working fluid in the flat collector is a low temperature resistant liquid, it can be maintained at minus 40 degrees without freezing. So even in alpine and cold areas it can operate normally all year round.
The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet the use of hot water by people in life and production. Solar water heaters are dividedinto evacuated tube solar water heaters and flat plate solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used.

Precautions for using solar water heaters:
1. Install the sun When the water heater is turned on, there may be a smell of dust or oil in the water line. 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. Keep the surface of theClean water heater can get higher heat. collection efficiency.
4. 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 turn on the cold water. 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.
