How do the Hills ESTEEM TM Solar evacuated tubes work?
Most Australians are familiar with flat plate technology when it comes to solar heating of water. Evacuated tubes are not as new as you might think, in fact they were developed over 30 years ago by an Australian at the University of Sydney! The technology was snapped up by Europe for very obvious reasons – it works extremely well in the cold! The Hills ESTEEM TM evacuated tubes are basically long cylinders – meaning no matter what time of the day, they face the sun and as long as there is light in the sky they will be absorbing the sun’s energy, in contrast to a flat panel which will only reach maximum efficiency in the middle of the day as well as sustain considerable efficiency loss due to reflection off the flat glass panel. The Hills Hills ESTEEM TM evacuated tubes have reached efficiency comparisons in winter of up to 160% greater performance than a standard flat panel.
