It can be damaged by frost. When the temperature is below minus 8 degrees in winter, it will freeze and crack. Solar tubes damaged by frost will permanently break and need to be replaced with new ones.
Particular attention should be paid to the antifreeze of solar water heater pipes, especially the connection between the water tank and the water pipe. This place is easy to shake when the wind is strong. If the connection is not good, the water pipe will be easily exposed. If there is no drainage of the solar water heater, it is easy to freeze and block, which will prevent hot water from coming out and cold water from coming out.
Therefore, water pipe insulation work must be carried out well. Generally, the length of an insulation pipe is two meters. The joints of each insulation pipe should be tightened with tape to prevent them from coming loosetent. when the wind is strong or the water is flowing.
Generally, solar water heaters are equipped with anti-freeze heating devices. Many users often use it to defrost the pipes after they are frozen, which damages the lifespan of the solar water heater. The correct usage method is that when the temperature remains below 0°C, the antifreeze device should be turned on to carry out preheating protection. If the nighttime temperature is relatively low in winter, the antifreeze device can be activated at night and turned off during the day.
Detailed information
Methods to prevent pipes from freezing
1. If the temperature is not very low, after using hot water, Night, refill the water immediately to reduce heat loss that night and make full use of thermal energy.
2. If the temperature is relatively low, get into the water after getting upthe next day. And put a small amount of water before bed or the next morning to prevent pipes from freezing and clogging.
3. If the sunlight is not strong that day and it is raining or snowing, you can fill half a tank of water or more than half of a tank of water as needed real.
4. If the water consumption is large, you can consider starting the electric heating of the solar water heater or putting the water from the solar water heater into the electric water heater to heat it slightly.
5. When the temperature is below 0℃, be sure to turn on the antifreeze device. After mastering these tips, you will be able to use your solar water heater well in winter.
