Eco XL

Hotels, hospitals, schools, sports clubs and centres; industry performance with domestic economy


Minimum of CO2 Emissions (Kyoto Protocol)


Hot water up to 60oC 24 hours a day, 365 days a year

Solar Thermodynamic solution to heat water for industrial use


Dramatically reduced water heating costs for sporting clubs, schools, hotels, gyms, retirement villages or other commercial/industrial operations with ENERGIE Australia’s ECO XL Thermodynamic Solar System. Eco XL is the latest generation in water heating. Using a high performance innovative technology that allows the user to benefit from substantial reductions in water heating costs while receiving a short return on investment (ROI). Users can heat water up to 60o C on rainy days or even during the night, thanks to the ECO XL innovative operating principle. The maintenance of the thermodynamic solar system is practically non-existent. the only requirement being an annual check the tank’s sacrificial anode. ECO XLs do not lose performance over extended years of operation. The capacity of ECO XL tanks range from 1000 to 6000 liters , with it being possible to link multiple tanks together for higher consumption needs.

Commercial ECO XL Installation

Solar Block 40 (40 Thermodynamic Solar Panels) with two 3000 litre tanks

This installation is a great example of not only the flexibility of the thermodynamic solar panel, but also how they can be visually integrated into the aesthetics of commercial buildings and structures.

  • Possibility of adapting into existing infrastructure without the need for civil construction works
  • Heat is captured through solar radiation and environmental temperatures
  • ECO XLs are able to provide commercial quantities of hot water at night and on cold days with little sunlight
  • The thermodynamic solar panels are light, discreet and are very versatile
  • ECO XLs contain an extremely efficient compressor, keeping energy consumption to an absolute minimum. This can be completely eliminated with integration into Solar PV systems
  • 3rd generation solar energy
  • Solar hot water up to 60ºc
  • Almost non-existent maintenance
  • Up to 3 cycles of ECO XL system’s hot water capacity per day

The Thermodynamics Solar System joins two incomplete technologies, the heat pump and the solar thermal collector.
Heat pumps are quite efficient equipment but the heat they produce from their renewable component varies only according to changes in the temperature of the environment.
Thermal solar collectors are the best source of heat on hot and sunny days but they are totally inefficient whenever there is no sun.

The Thermodynamic Solar Technology manages to surpass the limitations of both the heat pump and solar collector technologies.
Through the cooling liquid (R134a or R407c) which covers a closed circuit, the liquid goes into the solar panel and suffers the action of sun, rain, wind, environment temperature and other climate factors. During this process the liquid gains heat in a more favourable way than a heat pump. After this stage, the heat is transferred to an exchanger with the help of a small compressor, which heats the water. The liquid cools down and the circuit is repeated.

As the fluid has a boiling temperature of approximately -30ºC, the system works even when there is no sun, providing hot water at 55ºC, day and night, rain, hail, wind or shine, unlike the traditional solar thermal collectors.
The energy consumption of the system is basically the same as a fridge compressor that makes the liquid circulate. There are no ventilators that help the evaporation process, or defrost cycles, which lead unnecessary energy consumption.

The Solar Block controller is the interface between the equipment and the user. Among other functionalities, it gives access to:

  • System status
  • Temperature information through respective sensor
  • Programming (daily/weekly/etc)
  • Date and time information
  • Simplified parametrization
  • Outlets test
  • 12 predefined configurations
  • Integration in 3 circuits
  • 4 temperature sensors
  • Chrono-thermometre
  • 6 languages
