What is a wall-mounted solar water heater for balcony and what are its advantages and disadvantages

Balcony wall-mounted solar water heater is a new type of solar water heater invented by Beijing Solar Energy Research Institute (Samp Solar) and launched in 2004 to address the disadvantages related to the installation of high temperature solar energy. -raise residents and solve the problem of installing solar water heaters in medium and high-rise buildings. Compared with traditional solar water heaters, wall-mounted solar water heaters not only improve the thermal efficiency of balcony wall-mounted products, but also greatly eliminate the hidden dangers of traditional solar water heaters such as freezing, easy explosion pipes and easy leaks.

Advantages:

The wall-mounted solar power on the balcony is equipped with a pressurized water tank. This water tank can be connected to tap water. There will be no problem such as the traditional one. the supply ofSolar water and water pressure are guaranteed. Balcony wall-mounted solar power uses a thermal cycle method, so even if it is as cold as minus 30° in winter, there will be no freezing, and the safety performance of the system is relatively high.

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 external power devices. Photo and electricity can be used; if there is no sun, electric energy can be used for heating, so you can enjoy hot water even in winter when there is no sun.

Disadvantages:

The price is high and the installation cost is high. The current price of an ordinary 100 liter ranges from around 4,000 to 5,000 yuan. The water tank is relatively small. If used by one person, it can be heated by energysolar. If it is used by a family, it can only be heated by electricity.

Regional restrictions are relatively strong. Generally it's more convenient in the south, but in the north it's basically useless. If it is too cold, antifreeze must be replenished or replaced regularly, increasing after-sales costs.

Detailed information

When taking a bath, if the water in the wall-mounted solar water heater runs out and the person does not has not rinsed off, you can use it at that time. After a few minutes of cold water, through the principle of cold water flowing and hot water floating, the hot water in the vacuum tube is expelled and you can continue to take a bath. The quantity of water can be determined according to weather conditions to obtain a satisfactory water temperature. If the weather is good, you can fill the water slowly if it is cloudy or cloudyux, half a tank of water is enough if it rains; just keep the original water and do not add cold water.

When you take a shower at night, it appears that half of the hot water in the water heater tank is almost 70°C. At this time, in order to avoid excessive heat loss, the amount of water should be adjusted. be determined based on weather forecasts. On sunny days it is full of water; in cloudy and rainy weather, it is 2/3 filled with water. For hot and cold water adjustment, you can open the cold water valve, then adjust the cold water flow, then open the hot water valve to adjust and wait until the required bath temperature is reached .
