No. Solar energy must absorb light and convert it into thermal energy to heat water. Without strong light, there would be no hot water.
If you want to install it in your home..That's the case. It is preferable to install an auxiliary water heater. Usually use solar energy. If there is a problem, use an electric water heater.
This is the case in my house...haha.
< p>. First of all, wall-mounted solar water heaters have slightly lower heat collection performance than evacuated tube solar water heaters.
If the wall-mounted solar water heater maintains a temperature of 8 degrees for a long time, it is definitely an abnormal phenomenon.
Check if the wall sensor is protected from sunlight or covered in dust and should be treated immediately.
The internal heat collection circulation pipe should be checked for blockages or blockages.
Finally,check if there is any error between the temperature displayed on the temperature monitor and the actual water temperature to rule out if the temperature monitor is wrong.
Simple judgment:
There is an obstruction in front of the water heater and the sunlight time is short.
The water valves are not closed properly. ?
The water quality is not good and there is scale in the vacuum tube, which reduces the efficiency of heat collection.
The local air pollution is serious, and there is dust on the surface of the vacuum tube, which affects heat collection.
All the hot water in the water tank is used up, that is, there is no base water temperature, the capacity of the water tank water is small and water consumption is large.
Affected by weather conditions. Troubleshooting methods:
①Remove obstructions or relocate solar;?
②Replace faucet atwater ball;?
③Clean the vacuum tube;?
< p>④ Scrub the surface of the vacuum tube;⑤ Replace a large-capacity water heater or install an electric heating system
⑥ Analyze weather conditions and pay attention; the amount of water supplied to the water heater
