Anonymous users2024-01-24One. What are the advantages and disadvantages of balcony wall-mounted solar water heaters.
Advantages: 1. The balcony wall-mounted solar is equipped with a pressurized water tank, which can be connected with tap water, and there will be no problems such as traditional solar water and the water pressure is also guaranteed.
2.The balcony wall-mounted solar adopts the thermal cycle method, so even if the weather is cold to minus 30° in winter, there will be no freezing, 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 on the ground, it can supply water to the upper floors without any external power unit.
4. Photoelectric and photoelectric can be used together, if there is no sun, it can also be heated with electric energy, so that you can enjoy hot water in winter without sun.
Disadvantages: 1. The price is high, the installation cost is high, and the price of about 100 liters is about 4,000-5,000 yuan.
2. The water tank is relatively small, if one person uses hot water that can be used with solar energy, if a family can only use electricity to heat, the water tank is below 120 liters.
3. Regional restrictions are relatively strong, generally in the south and more practical, while in the north it is basically like chicken ribs.
4. If the weather is too cold, the antifreeze should be replenished or replaced regularly, which increases the after-sales cost.
5. The installation is complicated, but this is generally installed by workers.
6. The functional and practical efficiency of solar water heating is not very high.

1. Balcony wall-mounted building integration: The collector and water tank of the wall-mounted solar water heater are separated from each other, which is suitable for the installation of modern high-rise buildings, and can be flexibly installed on the roof, skylight, balcony and wall, without location restrictions, to achieve the perfect combination with the building. >>>More
Summary. 1. Before installation, you first need to determine the location, which can be based on latitude. >>>More
