. 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 exclude 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 water tubevacuum, 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 water ball valve;?
③Clean water tube vacuum;?
< p>④ Rub 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
What temperature can wall-mounted solar thermal oil reach?
The method of radjusting the temperature of this water heater The water heater is as follows:
1. When turning on the water heater After turning on the power, the water temperature will be displayed on the water heater.
2. When the water heater is turned on, if the water outlet switch is turned on, it is heating at that time, the water temperature will be displayed on the water heater.
3. If you want to adjust the water temperature during heating, simply adjust the water heater temperature increase button from 1 degree to 9 degrees. If you still want to adjust the temperature, wait until the water is adjusted. The water heater temperature is displayed. Set again.
4. If the set temperature is 4 degrees higher than the temperature at which the water enters, the water heater will start working.
5. Every 99 minutes of water heater use, the water heater time will be reset and recalculated.
6. If the buttonOn/Off is pressed while the water heater is heating, the water heater will stop heating.
Can reach 180 degrees. Solar water heaters heat thermal oil. Thermal oil absorbs heat quickly and has a high temperature. The maximum temperature can reach 180 degrees, which is much higher than the water temperature. thermal oil can quickly transfer heat to water. The heat transfer efficiency is high and the heating capacity is strong, which improves the heating effect.
