How to solve the problem that solar energy can't produce hot water in cold weather

1, water pressure problem. If the water pressure is too low, you can't supply water. Wait until the water pressure is high before draining water or buying a booster pump to ensure water supply.

2. Check whether the pipeline temperature is too low in winter, resulting in ice jam. In this case, sufficient sunshine can replenish water.

3. If it is a very old-fashioned solar water heater, such as a float, and there is no control instrument in the room. So floating may not work. At this point, the float valve or ball valve needs to be replaced. Instead, it is a new type of automatic water cut-off system of solar water heater, which does not need to change the original solar pipeline.

4. Check whether the solenoid valve is blocked, turn off the water switch and open the water inlet end of the solenoid valve. In this case, the very fine needle part can be carefully cleaned.
