As the name suggests, a wall mounted solar water heater means that the collector is installed on the balcony and the water storage tank is placed inside. Both are connected via a specific working fluid to transfer the heat absorbed by the sensor. to the water storage tank, thereby heating the entire hot water tank 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 valvesexhaust, but the high temperature liquid discharged may damage the decoration of the building;
2. If the exterior sensors are not installed in place, on this one. On the one hand, this will affect 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 energy industry exposed at the Huangming Exposure Conference raised alarm bellse among consumers. So, how to choose a wall-mounted solar water heater?
First of all, be careful to avoid overheating. It should be a combination of exhaust valve and expansion tank to prevent 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, inquire about 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 location. It is also attached with a specially customized bracket instead of a regular bracket; angle iron.
Third, it is necessary to understand whether the anticorrosion of the water tank is a double antic processorrosion of electronic anode and magnesium rod to ensure the safety of the water tank and the life of the whole machine.
The above is just my humble opinion, I hope it can help you!
It takes several hours to half a day for the balcony wall solar panel to conduct heat to the water tank after adding fluid. According to relevant public information, after the middle of the balcony wall-mounted solar equipment absorbs solar energy, it takes a certain time to transfer it to the water tank. This process must overcome interference and resistance to heat transfer caused by factors such as air and materials, so it takes some time. The intensity and duration of sunlight are important factors that affect the heat transfer efficiency of solar equipment. In case of bad weather or insufficient sunshine, the effectHeating from sunlight on the equipment will be reduced, thereby affecting the speed and efficiency of heat transfer. The distance between the water tank and the balcony wall-mounted solar device will also affect the heat transfer rate. If the water tank is too far away, heat transfer takes longer and longer pipes, resulting in slower heat transfer.
