The main reasons for the failure of solar energy insulation are:
1. The insulation layer of the water storage barrel is broken. Solar water is mainly stored in water storage barrels, relying on solar vacuum tubes to absorb heat. Hot water rises and cold water falls, completing the heat exchange and causing the water temperature to increase. prevent heat loss and cause a drop in temperature, so that the barrel insulation. Damage to the insulation layer will prevent solar energy from retaining heat.
2. The vacuum collector tube is damaged. It is very simple. As mentioned above, the collector tube is the main source of solar energy. If the collector tube is damaged, the solar energy will not exchange heat, so the water will not be hot at all, and of course. will not be isolated.

Solar water heater precautions:
1. Carry out a complete inspection before winter
Before winter, carry out a comprehensive inspection of the solar host and pipe connections, and replace the damaged parts in time to avoid cold accidents in winter. Users who do not use solar energy in winter should ensure that the water tank is full of water to prevent the vacuum tube from exploding and the rubber ring from being damaged by the heat and aging due to prolonged air drying.
2. Determine the amount of water supplied based on weather conditions.
In order to avoid excessive heat loss, it is necessary to look at the water in the sky, i.e. determine the quantity of water supplied based on the weather forecast, in order to obtain a more satisfactory water temperature. If the weather is nice tomorrow, fill-the water; if it's cloudy or cloudy, fill it with half a tank of water; if it rains all day, keep the original water without adding cold water;
3. When using an electric supplementary heater, be careful to avoid dry burning.
If a supplementary heat source is installed, you should regularly check whether the supplemental heat source device and the heat exchanger are working properly. For auxiliary heat sources heated by electric heating pipes, you must ensure that the leakage protection device works reliably before use, otherwise it cannot be used. When using the electric auxiliary heater, special attention must be paid to filling the water. The volume of water in the water tank should not be less than 50% to avoid dry burning without water. When taking a bath, take special carePlease be careful to unplug the power plug, and it is strictly prohibited to use it when it is energized.
4. Make sure the water heater can withstand strong winds
No matter how windy in winter, solar water heaters are installed outdoors, so the water heater and roof must be installed securely to withstand strong winds. In windy weather, the solar water heater can be filled with water to increase the wind resistance and bearing capacity of the water heater, and the electric heating, instruments and other power sources can be disconnected.
