Nowadays, when many families choose water heaters for their bathroom, they tend to choose solar water heaters. Because they are energy-saving, environmentally friendly and easy to use, they are favored by many homeowners and are mainly used. among residents of high-rise buildings. What is the approximate price of wall-mounted solar power for balconies? What are the advantages and disadvantages of wall-mounted solar energy? Today, the editorial team will explain to you the price of wall-mounted solar energy for balconies, let’s find out together!
Balcony wall mounted solar power price
Usually, the selling price is around 4000-4500 yuan for an 80L unit. The reason why it is so dear is its interior. the cost of parts is very high. For example, it uses the principle of heat transfer by natural circulation through tubesU-shaped. The water tank uses enamel as the inner tank and is made of 50mm thick polyurethane foam. The production cost is 2,000 yuan. Costs do not include company management fees, scrap rate, etc.
Advantages and disadvantages of wall-mounted solar energy
Advantages:
1. It is equipped with a pressurized water tank and can be connected to tap water, so it won't. There is a situation where the water pressure is not enough and the water does not come out.
2. It uses thermal cycle method, even if the weather in winter is below minus 30 degrees, there will be no frost, and its system is relatively safe, so we don't need to worry. on this subject. Security Question.
3. Its installation is relatively practical. Even if we install it on the first floor or ground floor, it can still supply water to upper floors without any devices.f external power supply.
4. Even if there is no sun and it is a cloudy and rainy day, we do not have to worry about its use, because it uses both light and electricity, and can also be heated by electricity. energy, so you can enjoy hot water even in winter when there is no sun.
Disadvantages:
1. Its price is relatively high, so its installation cost is also relatively high for ordinary solar power of about 100L, its price is about four to five thousand.
2. As its water tank is relatively small, if we use it alone, it is more suitable for solar energy. If we are a family, it is more suitable for electric or gas water heaters.
3. Its regional character is relatively obvious. Because it is directly affected by the sun, it is more widely used and more frequently used in the south, while it is moins used in the south.
4. If we encounter cold weather, we need to regularly replenish the antifreeze or replace it as soon as possible, which will practically increase the after-sales costs a lot.
5. Its installation is complicated and requires very high manual technology and installation level.
6. Its practical effectiveness is not very high.
Is the wall-mounted solar water heater good?
Useful.
Very useful, solar water heaters can provide domestic hot water. However, wall-mounted solar water heaters are not widely used and their maturity is relatively low.
This type of solar water heater is specially designed for high-rise buildings, used to hang on the wall outside the balcony. If a pipe bursts during use, the suction pipe bursts and the water splashes will fall directly into the lower part of the large building.uter, easily causing a dangerous accident.
The reasons why the wall mounted solar power is not hot:
1 Once the water in the wall mounted solar power is not 's hotter, you. First you need to check whether the installation angle is correct. Generally, the installation angle of wall mounted solar power is around 60 degrees. If the installation angle is greater than 60 degrees and forms a right angle of 90 degrees, wall-mounted solar power. will probably not receive solar radiation, which will therefore pose a hot water problem.
2. If there is a relatively large blockage in front of the wall-mounted solar panel, it will directly affect the sunlight. If the water is not hot because of the blocker, it needs to be cleaned. far in time.
3. If the heat collection area of the wall mounted solar power is not directly proportional to the capacity of the water tank, it will also cause the pproblem that the water is not hot when using wall mounted solar power. Solar energy. Right now we have to adjust it manually. Thermal collection area and water tank capacity of the wall mounted solar system.
4. After long-term use of wall mounted solar power, the indoor tank shows signs of damage very easily. If the indoor tank is damaged, the wall mounted solar will not be heated. In this case, it is necessary to act quickly. The problem can be solved by replacing the inner tank of the wall-mounted solar panel.
Do all residents of high-rise buildings use wall-mounted solar water heaters? They look good, but are they really good?
Okay, here they are. advantages and disadvantages.
Advantages of wall-mounted solar water heaters
1. Wall-mounted solar water heaters are equipped with pressurized water tanks. .This water tank can be connected to tap water and does not require problems such as traditional solar water supply and the water pressure is guaranteed.
2. Wall-mounted solar energy uses a thermal cycle method, so even if the weather is as cold as minus 30° in winter, there will be no freezing phenomenon, and the safety 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 high-rise buildings without any external power devices.
4. Photoelectricity is used together. If there is no sunshine, electric energy can be used for heating, so you can enjoy hot water in winter without sunshine.
Disadvantages of wall-mounted solar water heaters
1. High price and high installation cost.
2. The water tank is relatively small. If used by one person, it can only be heated by solar energy. be heated by electricity. The water tank is 120 liters.
3. Regional restrictions are relatively strong. Generally, they are more practical in the south but basically useless in the north.
4.If it is too cold, antifreeze needs to 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.
When I was passing through a community recently, I saw that many families had wall-mounted solar water heaters installed on their balconies, as shown below
Looks great, doesn't it? But is this wall mounted solar water heater real?iment good? Let me tell you about it below.
What are the advantages
The biggest advantages of wall mounted solar water heater? solar water heaters It does not take up space, which is great news for residents of high-rise buildings. And everyone knows that much solar energy cannot be used in winter. There is no need to worry about the wall-mounted type. , hot water can be used all day.
Another point is that solar energy cleaning is very troublesome. If mounted on the wall, it can convert solar energy into thermal energy. There will rarely be problems with scale or water leaks, and this is not the case. it must be maintained frequently. It's super practical.
What are the disadvantages
1 Before laying it, you must first lay hot and cold water pipes on the balcony, because this requires two pipes to enter and exit some water. If youthink about it later, you won't. Fortunately, the balcony is hidden.
2. The price of wall-mounted solar power is higher than the ordinary price, so everyone should consider it carefully when choosing.
Finally, the editor would like to remind everyone to pay attention to the quality of the water tank when purchasing. If the quality of the water tank is not good, the service life will be very short, so everyone. You have to keep your eyes open when buying. Meanwhile, there are two main types of wall-mounted water heaters on the market: vacuum tube and flat panel. You have to weigh which one to choose when buying. In fact, the effects of the two are similar in summer. but in winter, flat panel water heaters are not as efficient as vacuum ones.
