Evacuated Tube
Solar Hot Water Systems

Hills Solar Evacuated Tube Solar Hot Water Systems use the latest high-efficiency technology, which is now used overseas in millions of systems per year. Enviro Friendly is proud to promote this 'new' technology, in association with Hills Industries, suppliers of the Hills Solar range.

We are all familiar with the flat-plate solar hot water systems seen on roofs all over Australia, collecting the radiant heat from the sun to heat water. The collection plates are flat, which produces one limitation to efficiency- they can only operate at maximum efficiency when the sun is directly overhead at midday. At other times, the sun's rays are striking the collector at varying angles, reducing efficiency.

Hills Solar Esteem Evacuated Tube Solar Hot Water Systems overcome this problem. Because the collector consists of a series of tubes, the sun's rays are perpendicular to the tubes for most of the day, allowing the system to operate at high efficiency for much longer than flat-plate units. The diagram on the left illustrates this.

Another advantage of the evacuated tube technology, is that the weight problems caused by standard flat plate systems are eliminated.

Most flat plate systems weigh over 200kg. With an integrated 300l. water tank, this can place a 500-plus kilogram load on a roof- often requiring expensive modification. A standard 22-tube Hills Solar system weighs just over 80 kg on your roof, making it easy to position and instal.

Whether you are planning a new installation, or a retro-fit, Hills Solar Esteem Evacuated Tube Solar Hot Water Systems from Enviro Friendly World are a versatile, highly-efficient, low-maintenance solution to your solar hot water needs.

You can personalise your system, and choose from;

- your choice of storage tank sizes- from 250-330 litres

Just How Efficient Is Evacuated tube technology?
Evacuated tubes are far better at exchanging heat into water than flat plate technology. As the temperature of the water increases, the ability for any system to exchange that heat decreases. Evacuated tubes suffer much less from this issue.
