Water heaters are relatively common household appliances in our daily lives. Since electric water heaters consume a lot of energy, they don't burn electricity but money, so most people will choose other types. water heater. Evacuated tube water heaters and flat plate water heaters are two of the most common solar water heaters we have.
The difference between flat panel solar energy and evacuated tube solar energy: anti-scaling and anti-freezing performance
Using flat panel solar water heaters a double circulation system, which basically solves the problem. It eliminates the freezing problem caused by low temperature. On the other hand, because the whole cycle process is a closed cycle, the water heater has less scale, which can well guarantee the water quality. and create a good bathing environment for us.
The working temperature of vacuum tube solar water heaters is relatively high and the load capacity is relatively small, so it is easy for the tubes to explode. And because the bottom end is sealed, the water heater is prone to scaling and is difficult to clean. Even in the most difficult climatic and water quality conditions, efficient and stable operation can be guaranteed.
The difference between flat panel solar and evacuated tube solar: thermal efficiency
For water heaters, thermal collection efficiency is crucial. The national standard requires the instantaneous efficiency intercept of vacuum tube collectors to be greater than 0.62, while the instantaneous efficiency intercept of flat plate collectors is greater than 0.72. It can be seen that the heat collection efficiency of flat panel solar water heaters is better.
The difference between flat panel solar power and vacuum tube solar power: aesthetics
Due to its own limitations , the vacuum tube solar water heater is a semi-finished product and needs to be installed on site, which makes it difficult to transport and install. Additionally, a space must be set up on the roof to be used, so it cannot be integrated into the whole buildingand is therefore not very aesthetic.
However, the flat panel solar water heater can be perfectly integrated into the whole building. It looks great and is a complete product in itself. It is easy to transport and install, and is not easily restricted. by the site, and is more convenient to install.
The difference between flat panel solar energy and vacuum tube solar energy: the water temperature is stable
Because that the flat panel solar water heating system adopts the top water outlet method, the hot water and the tap water network are in collusion. The hot water pressure and cold water pressure are always consistent, and the water temperature is relatively stable.
Evacuated tube water heaters mainly use drop outlet and the pressure is very low and stable. However, cold water is affected by network pressureu of tap water. The water temperature after mixing is warm. and cold, especially in winter, which is very uncomfortable to use.practical.
The above is the difference between flat panel solar power and vacuum tube solar power. Taking a bath can improve the happiness of our lives, so when we buy a water heater, we should also choose suitable water. radiator according to their characteristics.
