Evacuated solar hot water systems

Apricus is an industry leader in solar hot water heating, utilising cutting edge technology to maximise use of the sun’s energy to heat residential and commercial water. The Apricus hot water system makes use of evacuated technology to maximise its effectiveness and minimise heat loss. Evacuated tube technology is a highly efficient, reliable solution suitable for the diverse conditions of the Australian climate.

One of the primary benefits of the Apricus evacuated solar hot water system is its ability to work in varied climates. The collectors perform well in winter conditions with temperatures below freezing because they have both glass wool and vacuum insulation. The cylindrical collectors are able to passively track the sun, allowing them to absorb energy throughout the day, rather than only during the midday hours. The tubes sit close to one another, so the unit does not require a reflective panel, and it also has minimal gaps between tubes to allow lost energy.

Cutting Edge Technology

What makes this system so innovative is its use of evacuated tube technology. Similar to an insulated flask used to keep hot beverages or soups warm in a lunch box, the tubes in the Apricus solar collectors are comprised of two glass cylinders fused together, with a vacuum in between the tubes. The outer layer of the glass is coated with an energy absorbing material, and the vacuum protects the system from heat loss, even in below-freezing temperature.

Inside of these tubes is a smaller copper tube that works as a heat pipe. It contains pure water inside a vacuum. The low pressure allows the water to boil at a low temperature, converting the liquid to steam which rises to the top of the heat pipe. This is where the heat transfer occurs, and the steam then condenses and runs back down the tube to begin the process again.

In addition, Apricus uses a unique spring assembly design, which keeps the contact between the heat pipe and the header pipe firm, allowing the unit to operate more efficiently in the heat transfer portion of the process.

Efficient, Effective Solution

The Apricus evacuated solar hot water system makes the most of solar energy to heat water for both residential and commercial buildings. Its innovative technology combined with its ability to work effectively in cold weather make it the leading choice for solar water heating for customers throughout Australia.
