Advantages and disadvantages of balcony wall-mounted solar water heaters

Everyone knows the advantages and disadvantages of balcony wall-mounted solar water heaters very well, because solar energy is almost universal in all homes. . But what do you know about wall-mounted solar water heaters for balconies? Let's take a look at the advantages and disadvantages of balcony wall-mounted solar water heaters.

Advantages of wall-mounted solar water heater for balcony

1. Wall-mounted solar water heater for balcony The water heater is equipped with a pressurized water tank, which can be connected to tap water, there will be no problems such as traditional solar water supply and the water pressure is guarantee.

2. The balcony wall-mounted solar energy adopts thermal cycle method, so even if the weather is cold up to minus 30 degrees in winterer, there will be no freezing phenomenon and the security performance of the system is relatively high.

3. The installation location is convenient Even if it is installed on the first floor or ground floor, it can supply water to upper floors without any power devices external.

4. Photo and electricity can be used if there is no sunshine, electric energy can be used for heating, so you can enjoy hot water in winter without sun.

Disadvantages of balcony wall-mounted solar energy

1. The price is high and the installation cost is pupil. The current price of an ordinary 100 liter is about 4. It ranges from about 1,000 to 5,000 yuan.

2. The water tank is relatively small. If used by just one person, it can be heated by solar energy. If it is used by a family, it can only be heated by electricityricity. the tank is less than 120 liters.

3. Regional restrictions are relatively strong, generally more practical in the south, but basically useless in the north.

4. If it is too cold, antifreeze must be replenished or replaced regularly, which increases after-sales costs.

5. The installation is complicated, but it is usually installed by workers.

6. The functional efficiency of solar hot water is not very high.

Product type

Flat panel balcony wall hanging: high thermal efficiency, metal tube plate structure, maintenance-free and cost-effective. The heat collection area is large and the heating is 360 degrees, so no sunlight is wasted.

U-shaped tube balcony wall hanging: there is no water leakage or scale in the vacuum tube, and long-term use term nwill not affect the efficiency of heat collection used by the system; steel connections, and there is no problem caused by silicone sealing rings Aging

Wall tower type balcony: large capacity, more energy storage.

Installation Precautions

1. Before installation, first choose the installation location, make sure the location installation site of the solar water heater is not a place of residential activity, and the installation site meets the product requirements.

2. If there is a wall bracket or extension part outside the wall and it faces the sun, the sensor can be fixed on it and reinforced with a plastic tripod. stainless steel and extended expansion nails. The length must exceed. The thickness of the wall;

3. If there is no wall bracket, you can use stainless steel brackets to fix the sensor to the wall on the wall insoleillé.

1. What is the working principle of solar water heaters. It mainly involves three processes: heat absorption, circulation and insulation.

2. Heat absorption. Firstly, the solar water heater passes through a special coating on the collector surface to well absorb solar radiation and prevent the emission of long-wave radiant heat. a hole. The heat pipe converts absorbed solar radiation into thermal energy, which can heat cold water.

3. Circulation, solar water heater reuses the characteristics of cold water being denser than hot water, cold water flows and hot water rises, forming cold water in the vacuum tube from top to bottom and heat The natural circulation of water from bottom to top makes the water temperature in the entire tank gradually increase.water and reach a certain temperature.

4. Insulation, then insulate the hot water through the outer tank, the polyurethane foam layer and the stainless steel inner tank of the insulated water tank. It will be convenient for everyone to use hot water at night.

Can solar water heaters be used in winter?

1. Can solar water heaters be used in winter? As shown in the working principle of solar water heater above, the answer to this question is yes. But if you want your solar water heater to work better in winter, there are some techniques. The principle is that the lower the temperature, the more water must be released several times and in small quantities, relying on the water temperature to increase the temperature of the pipes and prevent the pipes from freezing and close up.

2. If the temperature is notnot very low, turn on the hot water immediately after using it that night, this will reduce heat loss that night and make full use of thermal energy.

3. If the temperature is relatively low, get into the water after getting up the next day. And put a small amount of water before bed or the next morning to prevent pipes from freezing and clogging.

4. If the sunlight is not strong that day and it is raining or snowing, you can add half a tank of water or more than half a tank of water according to actual needs.

5. If the water consumption is large, consider starting the electric heating of the solar water heater or putting the water from the solar water heater into the electric water heater to heat it slightly .

6. When the temperature is below 0 degrees Celsius, be sure to activate the anti-freeze device. After mastering these tips,you will be able to use your solar water heater well in winter.

Safety Tips

1. When taking a bath, if the water in the solar water heater is used up and the person does not has not rinsed, you can apply cold water for a few minutes, use the principle that cold water flows and hot water floats, and the hot water in the vacuum tube is discharged and you can take a bath.

2Using principle A, if after taking a bath, there is still some hot water left in the Huangming brand solar water heater of Huangming Company and cold water is applied for a few minutes, the resulting hot water can wash an additional person. . (Each vacuum tube produces 6.5 liters or 8 liters of hot water)

3. Determine the amount of water supplied based on the weather forecast to obtain a more satisfactory water temperature: if the weather is nice, the water canbe filled, and on cloudy or cloudy days If it rains, the water in the tank will be filled with half a tank of water; if it rains, the original water will be retained and no cold water will be poured.

4. After taking a shower at night, if there is still half of the hot water near 70°C in the water heater tank, in order to avoid loss of excessive heat (the less water, the faster the heat loss), you should also adjust the temperature depending on the weather. The forecast determines the amount of water supplied. On clear days, the water supply will be full, and on cloudy and rainy days, 2/3 of the water supply will be. completed.

5. Hot and cold water adjustment: The steps for adjusting the water temperature of the Huangming brand solar water heater are as follows: open d first the cold water valve, adjust the cold water flow appropriately, then open the hot water valveto adjust until the desired bath temperature is obtained. Additionally, the amount of cold water can be determined empirically based on weather conditions. Be careful not to point the nozzle towards the human body to avoid burns.

6. Wind resistance measurements: Since the parts of Huangming brand solar water heater are reliably connected, the wind resistance performance mainly depends on its installation method and fixation. Currently, the solar water heater is fixed. with 8# galvanized iron wire and extended expansion bolts, forming a figure-eight shape at the front and rear, with good wind resistance. In addition, in areas with strong winds such as coastal areas, the effect will be better if the support is used. the structure is modified, or the backplate is removed and secured with steel strands used to secure telephone poles.

7. How to extendService life: In order to extend the service life of Huangming brand solar water heater, Huangming Group users should pay attention to the following points when using:

1). Water heater After installation and fixing, non-professionals should not move or disassemble easily to avoid damage to key components.

2) There should be no debris around the water heater to eliminate the hidden danger of hitting the vacuum tube.

3) Check the exhaust hole regularly to ensure that it is smooth to avoid inflation or deflation of the water tank.

4) When cleaning the vacuum tube regularly, be careful not to damage the end of the vacuum tube.

5) For solar water heaters equipped with auxiliary electric heating devices, special attention should be paid to water supply to avoid dry burning without water.

Some influence.

When a solar water heater is installed on a balcony, the duration and intensity of light received will be greatly affected, resulting in deterioration of the water heating capacity of the water heater solar.

After placing it on the balcony, a small hot water circulation pump should be installed on the hot water pipe to pressurize the hot water outlet of the solar water heater.
