The thermal insulation effect is not good. Split solar is different from rooftop solar. Additionally, the state-specified temperature for split solar is only about 70 degrees. it is usually 40 to 50 degrees in winter. In summer, the temperature is 50 to 60 degrees. This temperature can fully meet the hot water demand of the bath. Split solar energy does not mean that the higher the temperature the better. under high pressure for a long time, which will impact the life of the water tank liner. If it is outdoors, the temperature in winter is very low, which is not conducive to heat preservation.

As the name suggests, the wall-mounted solar water heater is a collector installed on the balcony, and the water storage tank is placed inside. Connecting the fluidThe working unit transfers the heat absorbed by the collector to the water storage tank, thereby heating the entire water tank to obtain the hot water needed for daily life.
The advantages and disadvantages of ordinary wall-mounted solar power are also very obvious:
Advantages: flexible installation location, perfect integration with the building;
p>Disadvantages: 1. On the market Many wall-mounted solar water heaters have the problem of rapid heat collection and rapid heat dissipation to varying degrees, that is, there is no hot water in summer/day, but no hot water in winter/night. Additionally, overheating issues will occur. Generally, wall-mounted solar water heaters will be equipped with exhaust valves, but the high temperature liquid discharged may damage the building decoration;
2. If the exterior sensors are not installed in place, on this one. From aOn the other hand, this will affect the collection. Thermal effects and, more importantly, violent incidents such as falls from high altitudes, car accidents and injuries;
3. Solar water heaters have water tanks that work for a long time in high temperature and high humidity environment, if the anticorrosion of the water tank is not done well, it will corrode and leak within a few years. Wall-mounted water tanks are usually installed indoors, and the consequences can be imagined.
So be careful when buying a wall-mounted solar water heater.
Last year, the series of bloody examples in the solar power industry exposed at the Huangming Exposure Conference raised alarms among consumers. So, how to choose a wall-mounted solar water heater?
First of all, be careful to avoid overheating. It must be a valve combination dexhaust and expansion tank to avoid overheating. Otherwise, if the heat transfer fluid leaks out and you have to ask someone to refill it frequently, it will be a minor problem, but the high temperature fluid splashed out will cause damage to the house and burn people.
Second, consult the installation situation in detail. In order to achieve the best heat collection effect, the collector inclination angle of a wall-mounted solar water heater is generally +10 degrees from the location dimensions, and it is fixed with a specially designed bracket. personalized instead of an ordinary angle;
Third, it is necessary to understand whether the anticorrosion of the water tank is a double anticorrosion process of electronic anode and magnesium rod to ensure the safety of the water tank and the service life. entire machine life.
The above is just my humble opinion, I hope it can help youhelp !
