Solar water heater does not water what is the reason

There may be several reasons: 1. If the control panel shows no water, you can put hot water to see if it is actually empty, because sometimes the sensor will fail to send the wrong signal to your control panel, it looks like there is no water, but there is water. 2. If the actual water is not released, it must be that the water tank has been empty, and the water has not gone up, it may also be a solenoid valve failure, and the solar water must be fed through it, and it will not be watered without work. 3. After the water is found that the solenoid valve is good, you can suspect that there is a leak point, and stick your head out of the window to see if there is a waterfall, because it is estimated that the water does not go up, either it is a huge leak (the reason for the waterfall), or the solenoid valve does not go up at all. 4. If your home is a very old-fashioned solar energy, float type water, the kind of indoor control instrument. There is also the possibility that the float is bad and the water is not filled. 5. The last one may be the internal failure of the water heater, so that the system can not work normally, it is recommended to take to professional maintenance. Solar water heater is a heating device that converts solar light energy into heat energy, heating water from low temperature to high temperature to meet people's hot water use in life and production. Solar water heaters are divided into vacuum solar water heaters according to the structural form plate solar water heaters, mainly vacuum solar water heaters, vacuum heat collection using the principle of hot water floating cold water sinking, so that the water generated microcirculation and get the required hot water.
