Are solar tube collectors more efficient than flat plate collectors?
Most solar water heaters use “flat plate” technology which has been around for many years. It works, but now there is a better alternative. Aeodexia Solar water heaters use state-of-the-art technology based on evacuated glass tubes and highly efficient heat transfer techniques. Flat plate solar water heaters are only at their maximum efficiency in the middle of the day. A great deal of the sun’s energy is simply reflected off the flat glass panels, especially in the morning and afternoon. Because the evacuated tubes in an Aeodexia Solar water heater are cylindrical, they are always facing the sun and therefore they can absorb more of the sun’s energy. In fact, an Aeodexia Solar collector will absorb up to 40% more of the sun’s energy than a comparably sized flat plate solar collector. The tubes consist of 2 layers of borosilicate glass with a vacuum between these 2 layers. This evacuated layer in the tubes acts much like a thermos flask, retaining about 97% of the energy absorbed from
