    I'm going to take a look at this question and just make a personal opinion:

    1.The market is immature at the moment. After more than 20 years of development, vacuum tube solar energy has today's brilliant achievements, it is very popular in the city, but in rural areas and marginal cities, it has only been developed in the last 3 years, and the promotion of wall-mounted solar energy is also a matter of the last 2 years.

    Its scope of use is also relatively limited, can only be used in the new community, before the house has been renovated, unless the house has a pipe to the balcony, it is good to install the balcony wall-mounted solar water heater. For example, we currently have 2,400 households installed in a community in Changzhou, and only more than 1,000 households have been installed at present, and a community of more than 200 units has just been signed in Suzhou. I think after a few years of market testing, high-rise residential areas will use more and more wall-mounted products in the future.

    2.Short run times. The implementation of anything is a process, and it takes a period of time to implement.

    Even if the society is developing rapidly now, it also needs a process, just like the designation of a law and regulation takes a long time, although the transmission time is very short, everyone knows about this matter, but it takes a long time to implement, a new traffic law comes out, everyone's habit, there will definitely be a lot of drivers who violate it, but after running for a period of time, you will get used to it.

    3.**High. Wall-mounted solar water heater is more expensive than ordinary household solar water heaters, and the cost of pressurized water tanks and pressure-bearing collectors is much higher than that of non-pressurized vacuum tubes.

    To sum up, I think that wall-mounted is the development direction of solar water heaters, but it still needs a period of promotion before it will gradually become popular.

    Wall mounted solar hot water triumph pros and cons.

    1. Advantages of wall-mounted solar water heaters.

    1) Thermal insulation and anti-freezing: The wall-mounted solar water heater is driven by the temperature difference induction to open the hot water pump circulation, so it will never freeze, and its water tank is made of polyurethane foam as the insulation layer, so its thermal insulation effect is very good, and hot water can be guaranteed all year round.

    2) Beautiful appearance: The water tank of the wall-mounted solar water heater is cylindrical, with simple and smooth lines, beautiful and generous, so it can be adapted to the needs of the indoor installation position of each house.

    3) Economical: Wall-mounted solar water heaters save 90% energy compared with traditional electric water heaters, and the energy-saving effect is excellent.

    2. Disadvantages of wall-mounted solar water heaters.

    1) When the wall-mounted solar water heater is laid, it is necessary to install hot and cold water pipes on the balcony, and two pipes are needed to enter and exit the water, so if it is not done in the early stage, you can only go through the open pipe in the later stage, not the dark pipe, which will affect the appearance.

    2) In winter, wall-mounted solar water heaters need electrical assistance because they are limited by temperature. In other words, if you want to use hot water, you need to add electricity to boil, so it is more expensive.

    Now that science and technology are developed, everyone used to boil hot water for bathing, and now not only water heaters have appeared, but also constantly updated, and different types of water heaters have been introduced, and wall-mounted solar water heaters are one of them, so some people can't help but ask, what is the difference between this water heater and others? Let's take you to the end.

    1. What is a wall-mounted solar water heater.

    1. It belongs to the detached solar water heating system, the water tank is placed in the balcony, and the collector is placed on the balcony of the south façade of the building.

    2. Working principle: The flat plate collector tube is used to convert the absorbed solar radiation into heat energy. Using the siphon principle, the heat energy reaches the water tank and exchanges heat with the water, so that the water temperature in the whole tank gradually increases.

    3. Types of wall-mounted solar water heaters: one is that the water tank is placed in the balcony, and the collector is placed on the balcony of the south façade of the building. The other is a stuffy solar water heater that integrates heat storage and heat collection.

    2. Advantages and disadvantages of wall-mounted solar water heaters.

    Advantages: 1. Split installation: the collector part of the hot water system is completely separated from the water tank, the collector is installed outside (or inside) the balcony, and the water tank makes full use of the outdoor space of the balcony, which solves the problem that users of high-rise buildings cannot install solar water heating systems, and realizes the perfect combination of solar energy and buildings.

    2. Pressure operation, the water outlet pressure is sufficient (the cold water pressure must be sufficient), the water supply can be more pointed, the cold water can be released less, and the distance between the water inlet pipes is short.

    3. Less external insulation, relatively speaking, it is necessary to save a little bit of the cost of using electric heat tracing.

    Disadvantages: 1. The installation position of the wall-mounted solar water heater water heater is limited, and the wall-mounted solar water heater on the market is generally produced by natural circulation, due to the large resistance of the fine circulation of the natural circulation solar pipeline, the cold and heat exchange speed is slow, coupled with the harsh installation conditions of the pipeline, so the water tank must be higher than 50cm, if the collector is installed on the balcony railing, then the water tank must be hung high on the wall, and the height difference is small, resulting in slow heat exchange and low efficiency.

    2. The temperature is low, the maximum temperature will not exceed 75, and the auxiliary electric heating is basically maintained at 30-40 in winter.

    3. It costs electricity, because the wall-mounted solar energy is not hot in winter, it completely needs electricity assistance, so if you want to use hot water, you have to add electricity to burn.

    The above is the introduction of wall-mounted solar water heaters, wall-mounted solar water heaters are placed on the balcony due to the water tank being placed in the balcony, and the collector is placed on the balcony of the south façade of the building. It is very convenient for residents on high floors, and it is very popular, but this is also its limitation. At the same time, it also has the disadvantages of low temperature, electricity consumption, etc., even if it has so many shortcomings, it cannot hide its benefits, it has achieved the perfect combination of solar energy and building to a certain extent.

Wall-mounted solar energy is still not very popular, due to the fear of high-altitude projectiles smashing glass tubes, vacuum tube heat collection area is limited and other factors, and wall-mounted solar energy is more expensive than ordinary vacuum tubes. So it's hard to promote it in Shanghai. You can choose an air energy water heater, which can generally save about 75% of the electricity bill throughout the year. >>>More

I have been engaged in the research of split wall-mounted solar energy since 2005, during which I have also experienced 5 brands in Jiangsu and Zhejiang, all of which have been pitted by manufacturers and have to solve a series of after-sales problems, after countless failures and nearly 5 years of market testing, after many technical improvements and system upgrades, it has now reached the implementation stage of production and promotion and application. Although there are many wall-mounted products on the market now, but the real effect is almost minimal, limited by the installation conditions and light, most of their hot water is secretly heated by electricity (after the conclusion of the performance tracking test of more than ninety percent of the products on the market), which also includes well-known brands that come from behind (the key depends on what their profession does, if the cows come to do solar energy, they are fucking bullshit), in fact, most manufacturers are not their own production, It is OEM processing, and perhaps even they themselves still don't understand how to install and apply, so they have already been pushed to the market, often blinding dealers and cheating consumers. When you see several well-known brands of wall-mounted products like twin brothers at the exhibition, you will sigh at the imitation ability of our people. >>>More
