Water wouldn't run in the tube, so the heat delivery efficiency wouldn't be affected and no incrustion and no burst. The whole system would run normally if some of vacuum tubes broke.
The unique carbonic coatingis more reliable than the traditional AL-N/AL coating, and its ageing persistenceis better, the coating property is longer.
Manifold Solar Collector adopts Nanometer molecular engineering which is applied to greatly improve the absorption function,the heat collecting ability increase 18%, the water temperature is higher;the same sunshine makes different hot water efficiency.
