The water that goes up to the solar energy is filtered with a water purifier, can it reduce the dirt

Formation of limescale in solar water heaters :

1. The continuous evaporation and concentration of water by heat causes the concentration of calcium, magnesium and salts in the water to increase, and when their concentration is exceeded, it will precipitate from the water to form a precipitate; 2. Water is heated, and bicarbonates are heated and decomposed, forming insoluble precipitates; 3. As the temperature increases, the solubility of some salts gradually decreases, and precipitates out. Impurities in tap water and dirt formed by the death of microorganisms in the long-term use of solar energy. These sediments, impurities, and dirt stick to the vacuum tube wall, forming insoluble scale.

Solar Water Heater Descaling Method:

1. You can buy a special solar water heater cleaning liquid on the market, its main components contain, food acid, synergist, metal material protector, etc., in fact, the most important thing is white vinegar, white vinegar is an aqueous solution containing acetic acid, acetic acid reacts with calcium and magnesium compounds to form soluble calcium acetate, magnesium acetate, so as to remove scale, other components are mainly to improve efficiency and protect the inner tank, in fact, the inner tank is a stainless steel product, as long as the acidic substance does not soak for a long time will not be harmed, Generally, soaking for about 10 minutes is enough, and the effect is better with warm water. 2. When using solar water heaters, it should be noted that when the water temperature in the water tank is lower than 75 degrees, it is not easy to produce scale, so in summer or spring and autumn, water should be added according to the weather conditions, if the sun is good, the water in the water tank should be added with use, so that the water temperature will drop with the addition of tap water to avoid the generation of scale.

It can be reduced, but there will still be solar temperatures in the 100s during the day.

There are only benefits and no harm to solar water heaters after cleaning.

Benefits::

1. Shorten the heating time.

If the solar water heater is not cleaned for a long time, thick dust will accumulate on the collector pipe, and there will be scale inside the water tank. The solar water heater mainly absorbs the heat of the sun to work, so the dust will affect the heating efficiency of the water heater, and the heating time of the solar water heater will be longer and longer. If you wash it regularly, the heating efficiency is improved, and the heating time is shortened.

2. The water quality is healthier.

Solar water heaters that have not been cleaned for a long time will have scale in the tank liner, water pipes, and sprinklers, which will affect the water quality. In the long run, the water quality will deteriorate, which is not good for the human body and the world. Users clean the solar water heater regularly, and if they are not at home for a few days, drain all the water in the solar water heater to ensure clean and flowing water.

Healthy water quality is good for health and maintenance. <>

Precautions for using water heaters:

1. Precautions for using solar water heaters - do not replenish water immediately.

Even in the severe winter, the water tank must not be replenished immediately after the water is empty, because the vacuum tube can reach about 2500C when the vacuum tube is empty, so there is no water in the water tank or the water must be carried out before sunrise or half an hour after the sun sets, in order to prevent the pipe from exploding.

2. Precautions for using solar water heaters - pay attention to prevent dry burning when using electricity-assisted heating.

If an auxiliary heat source is installed, the auxiliary heat source device and heat exchanger should be checked regularly to see if they are working properly. For the auxiliary heat source is heated by an electric heating pipe, it is necessary to ensure that the leakage protection device works reliably before use, otherwise it cannot be used. Special attention should be paid to water supply when using auxiliary electric heating, and the water volume in the water tank should not be less than 50% to prevent dry boiling without water.

When taking a bath, special attention should be paid to unplugging the power plug, and it is strictly forbidden to use it with electricity.

3. Precautions for using solar water heaters - correct use of electric heat tracing.

When installing heat tracing, we must pay attention to choosing products with good quality to ensure that they can be used normally and reduce hidden dangers. When using the heat tracing, pay attention to turn off it in time after thawing, and try not to use it when the voltage is unstable.

4. Precautions for using solar water heaters - make sure that the water heater can withstand strong winds.

In winter, solar water heaters are installed outdoors, so the water heater and roof should be installed firmly to resist the invasion of strong winds. In case of windy weather, the solar water heater can be filled with water to increase the wind resistance and load-bearing capacity of the water heater, and disconnect the power supply such as electric heating and instrumentation.

The scale of the solar water heater is of no use value. The main hazards of scale to solar water heaters are: 1. Scale adheres to the inside of the solar collector tube, resulting in the heat absorbed by the collector tube cannot be transferred to the water in time, resulting in the local temperature being too high and it is easy to blow up the pipe; 2. The scale adheres to the surface of the inner tank, causing corrosion under the scale, resulting in water leakage in the water tank; 3. The scale adheres to the wall of the electric heating pipe, causing the internal temperature to be too high, burning the heating wire or cracking the electric heating pipe sleeve, and causing accidents such as leakage; 4. Due to the small aperture of the shower head, the scale will block the shower head, causing the water heater to fail to produce hot water; 5. The scale is attached to the sensor, and the water temperature and water level can not be correctly perceived, so that the sensor probe in the water storage tank fails, which is easy to cause misoperation, so that the auxiliary heating electric heating pipe is dry burned or the water solenoid valve is not closed, and there are problems such as running water, in addition, the scale contains harmful substances such as nitrate and nitrite, which seriously endangers people's health.

6. The heat conductivity of scale is very poor, only less than 1% of iron, copper metal or glass, the heat absorption of water decreases, and the heat absorption of water is insufficient due to the thermal barrier of scale on the side of the water in the vacuum tube, and the temperature of water is difficult to rise;

Yes, cleaning a solar water heater is not only a hygienic habit, but more importantly, it is more important to extend its service life. If it is not cleaned for a long time, the scale accumulated in the vacuum tube will affect the heating efficiency and hot water quality, and if the scale is too thick, it will cause the heat in the vacuum tube to be difficult to dissipate, and even have the risk of bursting.

Cleaning steps: 1. Open the water inlet of the solar water heater and pour in an appropriate amount of descaling liquid.

2. Let the water heater automatically heat cycle for about 30 minutes, so that the descaling liquid can fully contact all parts.

3. Open the drain and drain the cleaning liquid.

4. After the water tank is filled with water, it will automatically circulate for 2-3 minutes.

5. Drain the circulating water and complete the cleaning work.

Here's how:

Method 1: If you know a little basic skills, you can remove the solar vacuum tube according to the instructions, pour an appropriate amount of white vinegar (the high white vinegar made by the factory is poured into the water tank) and soak for 10 minutes, and then pull back and forth with a brush, toothbrush, etc., to remove the remaining scale, and then pass the water twice.

Method 2: 1. Remove the vacuum tube (be careful, it is more difficult), or open the water inlet of the solar water heater and pour the white vinegar into the water storage tank.

2. Automatic thermal cycle for 30 minutes, so that the white vinegar solution fully touches all parts to clean the scale, and then open the drain to drain the white vinegar that has been cleaned and scaled.

3. After filling the water tank with water, recirculate it for 2 minutes, and then drain the circulating water, then the cleaning and descaling will be completed.

Note: The vacuum tube soaked in white vinegar or the vacuum tube washed by the circulation method will have some sour and unpleasant smell, if you hate it, you can scrub it with lemon juice or add some lemon juice to remove the smell after cleaning. However, the sour white vinegar smell is not a big fecal smell, don't be afraid.

The molecules that waft into the house with white vinegar can also prevent colds, killing two birds with one stone. 】

How it works

Principle of heat collection. Solar water heaters convert sunlight energy into heat energy and heat water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, and vacuum tube solar water heaters are the mainstay, accounting for 95% of the domestic market share.

The vacuum tube household solar water heater is composed of a collector tube, a water storage tank and a bracket and other related accessories, which mainly rely on the collector tube to convert solar energy into heat energy. The heat collector tube Sono uses the principle of hot water floating and cold water sinking, so that the water can produce microcirculation and achieve the required hot water.

The scale in the solar can be removed with acetic acid or citric acid.

The main components of scale are calcium carbonate, basic magnesium carbonate, magnesium hydroxide, etc., and strong acids such as hydrochloric acid are not recommended, and metal parts and seals of solar energy are easily damaged with strong acids. Weak acids such as acetic acid or citric acid can be used, and its calcium salts and magnesium salts are soluble in water, which not only cleans up the scale, but also does not damage the parts of the solar energy, even if it is not clean, there is no harm to the human body.

Completely removing limescale from a solar water heater is so easy, saving money and trouble!

1. Solar water heaters don't cost money to clean! With just a small method, the limescale can be removed quickly and effortlessly.
