When you enter winter, first check the condition of the solar water heater pipes. Pay attention to check whether the screws of the pipe fittings are loose and whether the pipes are cracked, disconnected or leaking.
For solar pipes, it is better to wrap them with foam, cotton and linen fabric, plastic, etc., which can play a role in insulation thermal.
Solar water heaters have electric heating tapes When the temperature is below freezing, electric heating tapes should be turned on to protect the solar water heaters.
When the temperature is extremely low or when solar energy is not used for a long time, the original water from the solar water heater should be recovered in a bucket and drained. This way there is no water in the water pipe and it will naturally not freeze.
Points to note when usingn of solar water heaters in winter: 1. Determine the amount of water supplied based on weather conditions. In winter, the sunlight is not strong and the lighting duration is short, so the amount of solar radiation that the vacuum tube can absorb is greatly reduced in order to obtain a relatively high water temperature. satisfactory and maximize the benefits of solar energy. Water supply can be determined based on weather forecasts. After exhausting the water at night, if there is still half of the hot water left in the water tank, in order to prevent the heat from dissipating too quickly, if the weather is good the next day, refill -water if it rains; or snowy the next day, fill it with only 1/3 of the water.
2. Use water from the water heater wisely. In winter, you can use the solar water heater normally on sunny days. When the temperature is lowerabove -5°C, use water from the water heater in small quantities and several times a day.
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 certainly crack and need to be replaced. the news.
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 ch jointsaque insulation pipe should be tightened with tape to prevent them from becoming disconnected. 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 energymic.
2. If the temperature is relatively low, get into the water after getting up the next day. And put a little water before going to bed or the next morning to prevent the pipes from freezing. Blockage.
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.
