Although water heaters are very common now, there are still some differences in the water heaters we use.

Lack of light is indeed a major enemy of solar water heaters, but with the progress of heat absorption and insulation technology, solar water heaters can still appear where there is lack of light. The heat absorption performance of solar water heater is closely related to its vacuum collector. The collector tube shall be able to absorb visible light to the greatest extent, and the heat collection performance and stability can be compared.

2. Step 2. The upper valve is damaged or not closed in place, so that the water tank is in a slow upward or downward leakage state, and the hot water in the water tank overflows or leaks.

For the water supply time of solar water heater, the best choice is to supply water before sunrise or two hours after sunrise when the non high temperature air is dry. This is because the collector plate of the solar water heater can quickly collect heat and keep warm. Therefore, if the solar water is heated in high-temperature air, it is easy to cause failure because the water temperature is relatively low and the solar temperature is high, because f temperature difference is large.
