First: The solar sewer pipe is frozen.
Two: Maybe the water line is blocked.
The water coming out of the solar water heater is not hot
Reason: There is a lot of dust deposited on the surface of the vacuum collector tube and the plate reflective or there are obstructions; the vacuum collector tube leaks and loses vacuum; the heat pipe fails, the weather is not good, the solar radiation energy is insufficient, the water valve is not closed tightly, and the water fills or flows slowly; .
Solution: Take the following measures according to the above reasons: wipe off the dust on the surface of the vacuum collector tube and reflector, remove the obstruction; replace the vacuum collection tube; replace the heat pipe; use an electric auxiliary heater; to squeeze. Seal the valve or check the quality of the valve and replace the water valve parts.
