Evacuated glass tube technology is a revolutionary solar water heating system designed specifically to provide maximum free energy to heat hot water. Its design has come about due to worldwide concerns with global warming and government programs to cut greenhouse emissions into the atmosphere. In the last decade, we have seen dramatic advances in solar collector performance and energy efficient building designs as well as a shift in people's awareness and expectations of energy efficient products. As a company, our objectives are to provide and develop energy free water heating solutions and re-educate the public on how to use these products to maximize efficiencies and comfort levels. - Basics of Evacuated Tube Technology An evacuated tube is a double glazed vacuum sealed tube. Borosilicate glass is used in the manufacturing process due to its ability to handle the stress caused by extreme temperature differences. Most of you know this as 'Pyrex' kitchenware. The vacuum seal in between the inner and outer tubes forms excellent insulation keeping 97% of the heat gain in. This is much like a Thermos flask. The inner tube has a special 'Novel Sputtering' which was developed and patented at Sydney University. Light energy, even on cloudy days, is absorbed and turned into heat energy. On a Global level, evacuated tubes are the highest performing and biggest selling systems due to their ability to absorb solar energy even on cloudy days, which in turn, provide excellent efficiencies over the winter period. When averaged out over an entire Australian year, evacuated tube collectors can increase efficiencies at least 40% more than a standard flat plate hot water system. Because of these design principles, it makes evacuated tube solar systems ideal for use with hydronic heating. |
