Once the solar water heater is frozen, the problem can be solved by using the solar defrost function.
This means keeping the water heater warm, melting ice and defrosting. This is used in winter. Click this button to activate the antifreeze belt to prevent the upper and lower water pipes. freezing and blocking. This means installing heating tape on the solar water supply and drainage pipelines, and using the heating tape to heat the pipeline to keep the pipeline at about 10 degrees, which not only prevents the pipeline from freezing and block, but also thaws the frozen pipeline. .
Solar Antifreeze Methods:
1. Antifreeze by running water
As long as the water continues to flow, the risk of freezing is very low. Before going to bed at night, you can turn on the hot water tap slightly and drip it slowly to ensureer that water flows through the water pipes. Remember to put a bucket to collect the water so you can use it the next day. Don't waste water.
2. Drain and prevent freezing
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.
3. Anti-freeze heating tape
Solar water heaters installed in the north all have electric heating tapes When the temperature is below freezing, remember to turn on the electric heating tapes. , which can effectively protect solar water heaters from freezing.
When the solar water heater is used in winter, due to the low temperature, it is easy to freeze, causing the water heater to fail to operate properly and supply water chauda. water. So, what should you do when your solar water heater freezes and no longer produces water? Here is a solar water heater winter maintenance guide to help you solve this problem.
Winter maintenance guide for solar water heaters
1. Pay attention when installing solar water heaters
When installing solar water heaters, you should consider climatic factors and choose. Suitable installation location. Try to choose a location that is sufficiently sunny, well ventilated and avoid accumulation of snow. At the same time, attention should be paid to the inclination of the water heater to facilitate drainage in winter.
2. Preparations before use in winter
Before using the solar water heater in winter, the water in the water heater should be drained to prevent freezing of the water pipes. At the same time, the inlet and outlet valves of the solar water heater should be closed to prevent water fromwater pipes from freezing in a low temperature environment.
3. Precautions when using in winter
When using solar water heaters in winter, you should pay attention to the following points:
(1) Maintain sufficient sunlight: Solar water heaters require enough sunlight to function properly and prevent freezing.
(2) Drain the water pipes regularly: Drain the water pipes of the solar water heater regularly to prevent freezing of the water pipes.
(3) Use insulating materials: Use insulating materials around water pipes and water tanks of solar water heaters to prevent heat loss and improve the efficiency of the heater water.
4. Handling the freezing problem of solar water heaters
If the solar water heater breaks down in winterIf there is a freezing problem, the following should be done:
(1 ) Close the valvewater inlet and outlet valve: to avoid further damage to the solar water heater.
(2) Wait for natural thaw: In sunny conditions, wait for natural thaw.
(3) Use a hot towel to defrost: Wrap the water pipe of the solar water heater with a hot towel and wait for defrosting.
(4) Use a hair dryer to defrost: Use a hair dryer to blow the water pipe of the solar water heater and wait for it to defrost.
