I spent ten years of solar energy, just a few days ago to find someone to deal with the scale, but still not hot, some people know what the reason
This requires the actual view to know, to find a good weather, it is estimated that the water in the solar water tank under normal circumstances should be hot, then go upstairs to the actual view, touch the vacuum tube
Used for so long, the efficiency is certainly low, clean up the scale, not hot, then the problem is the insulation cylinder, a long time, poor thermal insulation, the temperature can not be retained. Suggest you change a new set of,
In addition, if the water feeding mode is automatic, to see whether there is water tank Water Leakage problem, if there is Water Leakage fault, the tank slowly go out Water Leakage, and tap water has continued to add cold water to the water tank, the water in the tank will not hot.
If you feel the temperature, and the color white, the vacuum tube has been lost since the insulation function should be better for the new vacuum tube.
