Evacuated tube solar hot water
These high efficiency systems uses the latest Technology Evacuated Tube Solar Collectors available, and are
manufactured to Australian Standards AS/NZS 2712 and AS 3498.
Each solar collector module integrates 16 all-glass evacuated tubes, 16 U
shaped copper heat absorbers, and 16 aluminum fins, into the solar collector frame.
The solar collector module is located separately from the Hot Water tank and the capacity
of the tank is ‘sized’ to the number of solar collectors installed, and the expected water
usage profiles.
There are many variables to consider before choosing the optimum system, it's a specialist job so please let us do that for you.

Note: Not suitable for bore water conditions |
Features and operational principle
The solar collector module is the most efficient, reliable and maintenance-free type of evacuated
tube solar collector on the market today and does not require a high mounting angle
of the solar collector frame (just greater than 5 degrees on a flat roof). The selective coating inside the inner glass of the evacuated tubes ensures high energy
absorption and a low heat radiance loss, which converts solar energy into heat energy.
This heat energy is then transferred via the copper tubes and the
aluminum fins to the solar collector manifold (There is over 48 metres of copper tube heat absorber in each module. The Water in the
collector manifold is recirculated through the
storage tank and back into the collector module(s).
Temperature sensors
in the solar collectors on the roof and the water in the storage tank feed data into the controller. The controller starts the pump when it determines that there is sufficient differential temperature to heat the water in the tank, and stops it when the solar gain has been harvested.
When the solar gain is insufficient to raise the water temp to 60oC, the system will operate its heater (This process is necessary to kill harmful bacteria in the water)
GAS/LPG systems When hot water is required, the hottest water is drawn from the top of the storage tank, another sensor determines if the water is above 60oC, if it is not it will operate the inline gas water heater.
Electric Systems
The solar-electric system is different as it needs to heat all the water in the tank to 60oC (usually at night). It is cheaper to buy and install than the GAS model but our heat pumps offer a more efficient solution. Our heat pumps will generally use less electricty per year than an electric solar unit, operating its electric element to maintain adequate water temperature. The solar-electric should only be considered if there is some other reason why a heat-pump will not be suitable. |
A note about Electric/Solar Units
It is commom practise to turn off the electric element "as it is not needed", and only turn it on when the water temperature delivered is considered too low. This practise is not recommended - the heater element is only ever activated when required and if it wasn't needed it would not operate. If you turn it off you open yourselves to bacterial infection - ONLY TURN OFF THE ELEMENT IF YOU ARE AWAY, AND TURN IT BACK ON AS SOON AS YOU RETURN.
Split solar system features:
- The higher heating efficiency is obtained by flowing the water into the manifold, down and up each and every U Tube, unlike other evacuated tube solar collectors.
- Frost tolerant, certified down to Minus 25oC
- over 3 metres of copper heat absorber in every tube !!
- Marine Grade Stainless Steel tank. (ideal for solar storage tanks as water from the solar panels in summer can be above 90°C. The stainless steel will not break-down from the high heat, providing a much longer lifespan and therefore a better return on investment. Vitreous enamel (glass-lined) tanks will crack and rust out typically in 5 to 7 years - just as the warranty runs out!) We only recommend Stainless steel tanks for Solar (Not suitable for bore water)
- The Gas heater provides continuous hot water, regardless of whether the tube boosters provide any solar gain.
- Insulation properties of the vacuum in these solar evacuated tubes allow up to 97% of the heat from the sun to be retained. (12 sputted layer, tri-chlor coating.)
- Each manifold and all copper U pipes are solidly constructed and welded as one completely sealed unit, and then pressure tested to 1,700 kpa (more than 3 times the maximum operating pressure).
- Made to withstand high pressure mains water systems. No water directly inside the
evacuated tubes. Can continue to operate even with broken tubes. (obviously with reduced performance)
- Systems can be set up with ring mains for domestic or commercial applications.
Key Benefits of these LATEST TECHNOLOGY Solar Hot Water Systems
- The storage tank can be located internally or externally.
- The gas unit and storage tank are fitted at ground level, and only the solar booster collector tubes on the roof.
- Smaller profile, lighter collectors than others means less weight on the roof, so no reinforcing of the roof structure is required.
- No removable connections, so no possible leaks, and they are maintenance free.
- In NSW for example, these units can save you up to 83% of your hot water heating costs.
- Individual tubes can be replaced if required, at cost of approx $25 per tube (+ delivery & labour)

Overall installed cost of individual models will vary in accordance with, state, territory & zone rebates, existing conditions, delivery and installation costs.
Systems are available with 2 or 3 collector modules (each with 16 tubes), and either 264Lt or 327Lt stainless steel storage tank with Natural GAS heater (LPG and Electric systems are also available, however we do not recommend these systems as our 264-SS and 327-SS heat pumps offer a superior alternative): |
